Iron and steel production process (1) ironmaking: It is the process of reducing the iron in the sinter and block ore. (2) Shuo steel: It is to remove excessive impurities in the raw materials (hot metal and scrap steel, etc.) and add an appropriate amount of alloy components. (3) Continuous casting: the molten steel is then injected into the water-cooled junction by the intermediate tank. (4) Steel rolling: rolling into various types of steel by hot rolling. In the manufacturing process of each process will produce waste gas, mainly carbon monoxide, carbon dioxide, sulfur dioxide, nitrogen, hydrogen sulfide, hydrogen, methane and other gases, these have flammable, harmful gases, causing a great threat to production safety.
Dangerous goods such as acetone, methanol and alcohol used in pharmaceutical factories have buried great safety risks. In the production process will also produce hydrogen sulfide and ammonia and other harmful gases, harmful to human health.
In the process of power pipeline transmission, heating is easy to produce sparks, and the centralized setting of gas pipeline is easy to explode. The toxic gas leaking from the gas pipeline will cause harm to the inspection and maintenance personnel in the comprehensive pipeline gallery and cause poisoning phenomenon.
The oil field is mainly for oil and natural gas exploration and development; The combustion of oil and crude oil in the atmosphere will produce a variety of toxic and harmful gases. Mainly nitrogen oxides, carbon monoxide, carbon dioxide, sulfur dioxide and other gases.
Steel manufacturing process will produce waste gas, mainly carbon monoxide, carbon dioxide, sulfur dioxide, nitrogen, hydrogen sulfide, hydrogen, methane and other gases, these flammable, harmful gases, pose a great threat to production safety.
