In order to solve the problem that the steel is too hard when the cold rolled strip is rolled and cast, the method and new technical scheme are analyzed to reduce the chemical composition of carbon, manganese, silicon and raise the final rolling temperature. In order to solve the problem of hot rolled coiling crack, reduce the inclusion content in steel, strengthen the deoxidizing and degassing analysis of hot rolled coiling crack, and explore the new influencing factors. The difference of composition control between hot rolled coil and medium thick plate for hull structure: the new dry clinker production line of 2×4800 tons/day and the professional casting of 2×12MW waste heat power generation project under construction in Hebei Province were put into operation in September 2010. After completion, the project will produce 5 million tons of new-type dry cement clinker and 3 million tons of high-quality cement annually, generating 200 million kWh of electricity annually, and strive to become the production base of new-type dry cement clinker and high-quality cement and the demonstration enterprise of energy conservation and emission reduction and circular economy in the Central Plains. Wu 'an develops steel, coking and other heavy industries, with large industrial waste residue discharge, large stock and low actual utilization rate. How to make full use of these industrial wastes to reduce pollution and protect the environment.
