薄板坯连铸和轧制薄规格产品均要求钢中残余元素含量低 ,而用一般的废钢冶炼很难达到其要求 ,必须用废钢代用品进行稀释 .本文通过对国内废钢及废钢代用品资源的调查研究 ,并通过配料计算 ,提出了珠钢 15 0t电弧炉冶炼在保证钢水质量并考虑成本的前提下的用于指导配料的炉料模型 .
Thin slab continuous casting and rolling thin specification products all require low content of residual elements in steel, but it is very difficult to meet the requirements by ordinary scrap smelting and must be diluted with substitutes of scrap steel.Through the analysis of domestic scrap and scrap substitute resources Through the investigation and calculation of the ingredients, the charge model for guiding the ingredients under the premise of ensuring the quality of the molten steel and taking the cost into consideration was proposed.
