The introduction of steel foundry products (part 2)

Where appropriate, the code draws on relevant parts of existing ILO instruments already, including: occupational safety and health in the iron and steel industry (Geneva, 1983); Safety in the use of chemicals at work (Geneva, 1993); Management issues and drugrelated alcohol in the workplace (Geneva, 1996); Technical and ethical guidelines for workers’ health surveillance (Geneva, 1998); Guidelines on safety management systems and occupational health (Geneva, 2001); Safety in the use of synthetic vitreous fiber insulation wools (glass wool, rock wool, slag wool) (Geneva, 2001); Ambient factors in the workplace (Geneva, 2001); HIV / AIDS and the world of work (Geneva, 2001); and Safety and health in non-ferrous metals industries (Geneva, 2003).

The annexes include information on hazard identification, risk assessment and control and, from relevant ILO instruments, information on workers’ health surveillance, surveillance of the working environment and establishment of OSH management system. As these instruments are updated, the references to them in electronic versions of this code adjusted accordingly. Information on exposure limits and on chemicals used in the iron and steel industry as well. The practical recommendations codes ILO practice intended for the use of all that, in the public and private sectors, responsible for the management of health and safety hazards of occupational specific (eg chemicals, heat, noise and vibration), sectors of activity (eg forestry, mining), or equipment. Not intended Codes of practice to replace national laws or regulations or accepted standards. They are drawn up with the objective of a directive, in accordance with the provisions of national laws and regulations, to all those who may be engaged, through social dialogue, in the framing of provisions of this kind or in programs layout prevention and protection at the national or enterprise levels.

They are addressed in particular to governmental and public authorities, employers and workers and their organizations as well as management and safety and health committees in related enterprises. Codes of practice are primarily designed as a basis for prevention and protective measures and are considered as ILO technical standards in occupational safety and health. They contain general principles and specific guidance which concern in particular the surveillance of the working environment and the health of workers; education and training; record keeping; the role and duties of the authorities, employers, workers, manufacturers and suppliers of competent; and consultation and cooperation. Should the provisions of this code of practice to read in the context of the conditions in the country proposing to use the existing guidance, the scale of operation involved and technical possibilities. In this regard, the needs of developing countries are also included.

The iron and steel making

For making iron-most, are the essential features of coke ovens and the blast furnace, where coke is produced from coal and iron ore is melted (reduced) to produce pig iron, respectively. The furnace is charged from the top with iron ore, coke and limestone; A hot air, frequently enriched with oxygen, blown in from the bottom; and the carbon produced from the coke transforms the iron ore into pig iron containing carbon, with the generation of carbon monoxide and carbon dioxide. The limestone acts as a flux. At a temperature of 1,600 ° C, the pig iron melts and collects at the bottom of the furnace. The furnace is tapped (ie the pig iron is removed) periodically, and pig iron is cast into pigs for later use (eg in foundries), or is poured into ladles where it is transferred, still molten, to the steel making plant. The waste gas from the blast furnace, which is rich in carbon monoxide, burned in blast furnace stoves to heat the air blown into the furnace and may be used as a fuel elsewhere in the steel plant.

Some pig iron is also produced in foundry cupola furnaces. Various processes exist or are under development for producing iron through the direct reduction of iron ore, using reducing gases. Such processes may be more important in the future.
The purpose of operations aa steel refine the pig iron which contains large amounts of carbon and other impurities. The need to reduce carbon content, the impurities oxidized and removed, and the iron converted into a highly elastic metal that can be forged and fabricated. Alloying agents may be added at this stage. Different types of melting furnace used in this process.

Some steel is produced directly from scrap or other materials containing iron, most often in electric arc furnaces, without the need for iron ore or coke.

Steel is cast into slabs, billets, bars, ingots and other shapes. A scarfing, pickling, annealing, hot and cold rolling, extrusion, galvanizing, surface coating, cutting and slitting, and other operations designed to produce a variety of steel products including subsequent steps.

The application of iron and steel foundry industry

This code of practice should provide guidance, in accordance with the provisions of the laws and national regulations, to:
(a) all those government authorities, associations of workers and employers organizations and industry, whether legislative or advisory, whose activities influence the safety, health and welfare of workers in the iron and steel industry;

(b) all persons at the iron- and steel-making facilities, ie employers, persons in control of premises, and workers and contractors, as appropriate to their duties and responsibilities for safety and health;

(c) all operations in the iron and steel industry.

OSH can implement some measures of health and safety to protect workers in the iron and steel industry would be affected, directly or indirectly, on the general environment. This relationship should be taken into account by the competent authorities and employers both in design and their respective policies and programs to implement.

Should the provisions of this code at least consider. It is not intended to replace the laws, regulations or accepted standards laying down higher requirements. Priority should be stricter requirements applicable beyond the provisions of this code. In the absence of laws and regulations on national OSH particular issue, should draw guidance from the code of practice, as well as other relevant instruments are recognized nationally and internationally. 1.2.4. References to the institutions responsible for the delivery and award of vocational education the code. Such institutions are advised to review existing curricula in the light of the recommendations of the code for training and allocation of responsibilities at work.

The introduction of steel foundry products (part 1)

In accordance with the decision taken by the Governing Body of the ILO at its 288 session in November 2003, held a Meeting of Experts on Safety and Health in the Iron and Steel Industry in Geneva from February 1 to 9 of 2005 to draw up and adopt a revised code of practice on safety and health in the iron and steel industry. The meeting was composed of seven experts appointed after consultation with Governments, eight experts appointed after consultation with ‘group and eight experts appointed after consultation with the Workers’ group of the Governing Body of Employers. Adopt original code of practice on safety and health in the iron and steel industry at a meeting of experts in 1981.

This new code, which reflects the many changes in the industry, its workforce, the roles of the competent authorities, employers, workers and their organizations, and the development of new ILO instruments on occupational safety and health focuses on the iron and steel and iron and steel basic products, such as rolled and coated steel, including from recycled content. It does not deal with the mining of raw materials for iron and steel production, which is covered by the Safety and Health in Mines Convention, 1995 (No. 176), and codes of practice on safety and health in coal mines (1986) and safety and health in surface mines (1991), nor does it deal with the fabrication of commercial steel products. The code of conduct is based on principles established in international instruments relevant to the protection of workers’ safety and health.

The first two chapters deal with the objectives and implementation of the code. The next two chapters address, within a national framework, the responsibilities, duties and rights of the competent authority, the labor inspectorate, employers, workers and their organizations, suppliers, manufacturers and designers, and contractors, and occupational safety and health (OSH ) management systems and services and OSH reporting. Part II of the code addresses different operations commonly used in the production of iron and steel – from coke ovens to steel furnaces and foundries, to rolling mills, coating lines and recycling. It also covers transport, competence and training, personal protective equipment, emergency preparedness, and special protection issues and hygiene. Each section describes hazards, risk assessment and provides guidance on eliminating or controlling risk.

The Special Steel Foundry

steel foundry (1)steel foundry is widely used in today modern industries. If we need shock resistant casting products, between the iron casting and steel casting, the steel foundry has more advantages. It finished pieces has many much more good properties. There are many kind of steel foundry products. Like heat resistant steel foundry works, corrosion resistant steel foundry, high tensile strength steel foundry. Based on different industrial need, we have a wide range selection of foundry products.

Steel foundry works are adopted in many industries that need more strength and shock resistant property. Also we use the different steel to make steel foundry finished products. Based on the different content of alloy, it can be divided into two types: high alloy steel foundry product and low alloy steel foundry product. Different industry need different type of steel foundry works. We can make many kinds of steel foundry parts with many kinds of size and shape.

We manufacture special steel foundry finished products by mixing special alloy into casting mixing compound. So that we can get special steel foundry with strong strength, fire retard property. In building material manufacturing, we widely adopt many kinds of steel foundry works due to their such good properties.
