为了进一步提高特钢生产的工艺技术和装备水平,以提高产品质量和竞争能力,一九八一年特钢生产技术工作会议确定:重点推广八项新工艺、新技术,即:炉外精炼、喷射冶金、电炉内工艺改革、铸锭绝热帽口和保护渣、氮基保护热处理、滚动导板、中速中负荷修磨及精密轧制。一年来各厂都做了大量工作,取得了一定的成绩,其中有些项目取得了较明显的经济效果。基本情况如下:1.炉外精炼:几年来一直受到各厂的极大重视。八一年各厂原有的精炼设备都进行了批量生产和工艺、炉衬材料的研究工作,
In order to further improve the technology and equipment of special steel production to improve product quality and competitiveness, the special steel production technology conference in 1981 decided to focus on the promotion of eight new processes and technologies, namely: furnace refining, Spray metallurgy, electric furnace process reform, ingot insulation cap and slag, nitrogen-based heat treatment, rolling guide, medium-speed load grinding and precision rolling. In the past year, all the factories have done a great deal of work and made some achievements. Some of these projects have made obvious economic results. The basic situation is as follows: 1. Furnace refining: Over the past few years has been the great attention of the factory. In 1981, the original refinery equipment of each factory had carried out batch production and process, the research work of lining material,
