What does metallurgical industry include?

Metallurgy can be divided into ferrous metallurgy industry, nonferrous metallurgy industry, rare metal metallurgy industry and powder metallurgy industry.

Metallurgical industry refers to the industrial sector that explores, mines, selects, smelts and rolls metal minerals into products. Including ferrous metallurgical industry (that is, iron and steel industry) and non-ferrous metallurgical industry.

Therefore, metallurgical industry should refer to industries related to smelting metals and providing ores (including mining, mineral processing and foreign trade exploration, etc.). ), metal material processing, metallurgical equipment (such as refractories), foreign trade related to metallurgy (such as concentrate import and metal export).

Main harmful factors in metallurgical industry production;

1, high temperature and strong radiant heat.

In metallurgical production, the processing, sintering, coking, ironmaking, steelmaking and steel rolling of mineral powder are all high-temperature operations, which are more prone to heatstroke. A large number of infrared rays radiated by hot objects are easy to cause occupational cataracts.

2. Dust.

In production, there are high concentrations of dust from underground mining, transportation, crushing to mineral processing, mixing and sintering. Long-term exposure will lead to pneumoconiosis, mostly cinnamon lung.

3. Carbon oxides.

The content of carbon monoxide in gas is about 30%, and carbon monoxide poisoning may occur if you don't pay attention to protection in the post where you are in contact with gas.

4. others.

Strong noise generated by air compressors, fans, rolling mills, etc. It is likely to cause occupational noise deafness; Because there are many chances of contact with flame, molten steel, steel slag and steel ingot, it is very easy to burn.

Workers exposed to high temperature radiation are prone to diseases such as fire erythema, pigmentation, folliculitis and skin suppuration; Because of the high temperature, intestinal activity is inhibited, which increases indigestion and gastrointestinal diseases, and the incidence of hypertension is higher than that of ordinary workers.
