The main sources of waste gas in the iron and steel industry are: (1) the transportation, loading and unloading and processing of raw materials and fuels produce a large amount of dusty waste gas; (2) The process of reproduction of various kilns in iron and steel plants will produce a large amount of dust and harmful vapor gas; (3) Waste gas emitted from chemical reactions in the production process, such as the waste gas generated during smelting, burning, chemical products and steel pickling. The main gases produced by the steel industry are: carbon dioxide, carbon monoxide, sulfur dioxide, hydrogen sulfide, etc. For this reason, "Shenyang Anshide Technology" provides a one-stop gas detection alarm control system for your safe production escort.
