FUCHS Systemtechnik自1989年开发竖炉技术以来,由于废钢在坚炉中预热的环保效应,其在电炉炼钢方面取得的收益在不断提高。为了满足最终产品残余元素含量越来越严的要求,同时由于简单的经济原因,使用DRI(直接还原铁),HBI(压铁)或铁水装料的交、直流技术已在全世界28个坚炉中得到了应用和验证。竖炉已证明是最为经济的冶炼工艺炉子这一,每天出钢可达到40炉。本文将在几个方面进行论证,重点集中在DRI/HBI选用和铁水装料上。依据铁水所占的百分比,电炉电耗可降到160kWh/t钢水以下。预热竖炉的投资用不了一年即可回收。
Since the shaft furnace technology was developed in 1989 by FUCHS Systemtechnik, the benefits of electric steelmaking have been steadily increasing due to the environmental benefits of scrap preheating in strong furnaces. In order to meet the increasingly stringent requirements for the residual content of the final product, AC and DC technology using DRI (Direct Reduced Iron), HBI (Ferroalloy) or hot metal charge has been adopted for 28 simple reasons The furnace has been applied and verified. Shaft furnace has proved to be the most economical smelting furnace, which can reach 40 furnaces per day. This article will be demonstrated in several areas, with a focus on DRI / HBI selection and hot metal charging. Based on the percentage of hot metal, electric furnace power consumption can be reduced below 160kWh / t molten steel. Preheat shaft furnace investment can not be recovered within a year.
