我国第一台大型耐火纤维炉衬热处理炉于一九七八年三月二十日在上海锅炉厂正式投产使用。该科研项目是由上海锅炉厂和一机部第二设计院为主设计研制的,协作单位有一机部八院、一院、北京耐火材料厂和洛阳耐火材料研究所。该炉是在原有3.5×16米台车式燃油热处理炉的基础上改造的,用于大型容器的退火和正火热处理。经常使用的退火温度为650℃,正火处理时为950℃。改成耐火纤维炉衬后,有效尺寸为4.7×4.7×17米~3。由于采用耐火纤维,炉墙减薄,扩大有效炉底面积35％,扩大有
China’s first large refractory fiber lining heat treatment furnace on March 20, 1978 in Shanghai boiler plant officially put into use. The research project is designed and developed by the Shanghai Boiler Works and the Second Design Institute of the Ministry of Machine Building. The cooperation units include a unit of eight homes, a hospital, Beijing Refractory Factory and Luoyang Refractory Institute. The furnace is based on the original 3.5 × 16-meter truck-type fuel heat treatment furnace, which is used for annealing and normalizing large vessels. Frequently used annealing temperature is 650 ℃, normalizing treatment is 950 ℃. Into the refractory fiber lining, the effective size of 4.7 × 4.7 × 17 m ~ 3. As a result of refractory fiber, furnace wall thinning, expanding the effective bottom area of 35%, expanding there
