今年以来,在公司、四厂两级的正确领导下,炼钢分厂在确保钢锭质量的前提下,积极推广代用料炼钢,对降低钢锭成本起了巨大作用.1995年1—9月做了以下工作:用硅铝钡代铝进行钢液终脱氧;喂铝线代替加铝操作;用钛材代钛铁冶炼20CrMnTi及ICr18Ni9Ti钢包中钛的合金化,钛的收得率两种大致相当;用镍渣、不锈钢屑经重熔处理作配料用;EF+VOD冶炼SUS304合理控制Cr和Ni成份;EF+VOD冶炼1Cr18Ni9Ti用高碳铬铁;用兰晶石不烧砖取代烧成高铝砖以及提高VOD钢包精寿命等.一共取得588.55万元显著经济效益,为长钢走出困境做出了重大贡献.1 电炉铁合金代用料应用
Since the beginning of this year, under the correct leadership of the Company and the fourth plant, the steelmaking branch has actively promoted the substitution of raw material steelmaking on the premise of ensuring the quality of steel ingot, which has played a significant role in reducing the cost of steel ingot. Do the following work: Si-Al barium substitution of liquid steel for final deoxidation; Al-fed aluminum instead of aluminum operation; with titanium on behalf of titanium iron smelting 20CrMnTi and ICr18Ni9Ti ladle titanium alloying, titanium yield roughly two Equivalent; using nickel slag, stainless steel scrap remelting ingredients for the preparation; EF + VOD smelting SUS304 reasonable control of Cr and Ni components; EF + VOD smelting 1Cr18Ni9Ti with high carbon ferrochrome; Aluminum brick and improve the life of VOD ladle, etc. A total of 5.8545 million yuan made a significant economic benefits for the steel out of the predicament made a significant contribution .1 electric furnace ferroalloy alternative materials application
