Forged workshop heat treatment process is mainly responsible for the heat treatment of special steel forgings. Since heat treatment furnace seal is lax and other reasons, Lead to forging material heat treatment rejection rate is higher, and add the workshop production of products are the high value-added products, so that caused large economic losses.So, the forged steel workshop heat treatment QC team will make reduce the forging material heat treatment rejection rate as this year's QC activity subject. Through the development of QC activity to make the forging material heat treatment rejection rate reduced to 2% from 3.33%.
