本文介绍一种生产中硅耐热铸铁的新工艺,对中硅蠕墨耐热铸铁的化学成份、稀土加入量、性能、生产工艺等,在理论和实践两个方面作了较详细地探讨和阐述。可以认为,用本工艺生产梳形卡、挡风板、喷咀等耐热800℃的另件,可以获得良好的综合经济技术指标,且工艺简便可行,一般冲天炉都能生产。 This article describes a new production of heat-resistant silicon in the heat of the new technology, heat-resistant silicon cast iron in the silicon componentry, the amount of rare earth, performance, production technology, in theory and practice in two aspects made a more detailed discussion Explain. It can be considered, with the production of comb cards, windshields, nozzles and other heat-resistant parts of 800 ℃, you can get a good comprehensive economic and technical indicators, and the process is simple and feasible, the general cupola can produce.
