电炉行业“七五”科学技术攻关项目——控制气氛热处理炉的重要配套材料抗渗碳砖,已由江苏省东台市耐火器材厂研制成功,并于1989年12月6日通过了省建筑材料工业局主持的技术鉴定。抗渗碳砖经过该厂两年多的实验室试验,工业性试制和试用以及测试,取得了预期的效果。已试制成功的KST-0.5、KST-0.8、KST-1.0、KST-2.0四种型号的抗渗碳砖,氧化铁含量小于0.7％,重烧线收缩率小,耐压强度高,导热系数低。有关专家认为,该砖在高温还原性气氛中能抵抗H_2、CO等强还原性气体的侵蚀,并具有较高的高
Electric furnace industry, “Seventh Five-Year” scientific and technological project - the control atmosphere heat treatment furnace supporting material impermeable carbon brick, fire-resistant equipment factory in Dongtai, Jiangsu Province, the successful development of the plant, and on December 6, 1989 passed the provincial building materials Industrial Bureau presided over the technical appraisal. Anti-carburizing brick after more than two years of the plant laboratory tests, industrial trial and trial and testing, and achieved the desired results. The KST-0.5, KST-0.8, KST-1.0 and KST-2.0 anti-carburizing brick have been successfully made, the content of iron oxide is less than 0.7%, the shrinkage of re-fired wire is small, the compressive strength is high and the thermal conductivity is low . Experts believe that the brick in high temperature reducing atmosphere can resist H_2, CO and other highly reducing gas erosion, and has a high high
