The occurrence and treatment of solid waste in iron and steel enterprises were introduced. In view of the existing problems in solid waste treatment in iron and steel enterprises, it was proposed to use the melting pyrolysis process for solid waste treatment. The furnace body of the melting pyrolysis furnace adopts a vertical structure, in which the high temperature melting treatment and slagiron separation of the hazardous waste and partially hazardous waste such as slag steel, inferior metallized pellets, some inferior social scrap steel, machined scrap and waste oil barrel, waste asbestos and waste cloth bag of the iron and steel enterprise were carried out to realize the solid waste treatment and resource recovery. And the cost of molten iron produced by the melting pyrolysis furnace was lower than that produced by blast furnace, and had good economic benefits. Melting pyrolysis furnaces can also coordinate the disposal of social solid waste, realize the coordinated development of steel plants and cities, and have good social benefits.
