Explanation

continuous casting refers to the energy-saving technology that is transported and loaded into soaking pit in hot state, which can make full use of heat energy of slab. The necessary conditions for adopting hot charging technology are: no macroscopic defects in the casting billet; Capacity matching of continuous caster and rolling mill: there are insulation, storage and transportation facilities from continuous caster to soaking pit; steelmaking - continuous casting and rolling processes shall be uniformly scheduled and coordinated; The soaking pit can both heat and maintain insulation. According to the charging temperature of continuous casting slab, the hot charging technology can be divided into: direct emulsion (charging temperature shall not be lower than 950-1000 ° C, and rolling can be carried out after proper temperature equalization); High temperature hot charging (charging temperature at As-900 ° C); Warm charging (charging temperature above 400 ° C but below A3). Obviously, the higher the furnace loading temperature. The greater the energy-saving effect.
