我厂从1983年开始,应用赣州有色冶金研究所生产的稀土硅铁合金试制新型的耐热材料——稀土耐热钢,不久取得了成功。该产品于1985年11月通过鉴定。到会代表一致认为:“稀土耐热钢产品的试制是成功的,在目前我国热处理领域的应用中,从材质和制作产品本身的可靠性、经济性等方面属国内先进,应予推广”。目前我厂用它制造的各种热处理炉用的工装吊挂具近500 I plant from 1983, the application of Ganzhou Institute of Nonferrous Metallurgy rare earth ferrosilicon alloy trial production of new heat-resistant materials - rare earth heat-resistant steel, and soon achieved success. The product passed the appraisal in November of 1985. Delegates to the meeting agreed: “Rare-earth heat-resistant steel products trial is successful, in the current application of heat treatment field, from the material and the reliability of the product itself, economy and other aspects of the domestic advanced, should be promoted.” At present, I plant with it to create a variety of heat treatment furnace with tooling hanging nearly 500
