1. Through optimization of steelmaking process, including optimization of new EAF lining preheating, oxygen supply, slag making, power supply curve, and optimal hot heel, current comprehensive production capacity is 60000 tons \/ month, future output will be hugher than 6000t\/m, but due to the shortage of Anshan scrap supply, sometimes it is forced to stop production;<\/p>\n
2. under a good quality refractory, we optimized laying type of refractory , avoided electrode fracture when charging the block, and electricity consumption is significantly reduced comparing with before, but there is still great room for improvement. If scrap management is strengthened, the life of EAF lining can reach more than 400 heats. The previous two EAF linings killed 32 hours of production time. According to average outpup 30 heats per day and single output 80 t\/h, company can raise output of 3200 tons according to EAF lining life reaching 380 times.<\/p>\n
3. Help to improve slag-making process and power supply process, and the life of EAF center block has been greatly enhanced. However, it is still difficult to promote the life to thousands times due to the use of low-grade corundum. If high-grade corundum is used, the life can reach more than 1000 Heats.<\/p>\n
4. If process is further optimized and the overall management of equipment and production is strengthened, EAF should reach designed capacity soon.The consumption of each index decreased evidently.<\/p>\n
5. The production efficiency has been significantly improved, and the production capacity has been increased by more than 30%.<\/p>\n
6. The comprehensive economic benefits have been significantly improved.<\/p>\n<\/div><\/div>
