宜兴县芳桥可塑性高温器材厂研制的“笼格式井式电阻炉节能炉胆”(简称“节能炉胆”)于一九八六年一月通过省级鉴定,现正在省内外推广,我公司选择洛阳第一拖拉机厂工具处热处理车间一台苏式75瓩井式渗碳电阻炉作试验。该炉炉体原用重质粘土砖砌筑,加热元件为螺旋形电阻丝,材质为Cr20Ni80,架在粘土砖小架板上,砌体外层用矽藻土粉进行保温,最外层为薄钢板壳,经热工测试其热效率为6.8％(按热效
Yixing County Fangqiao Plasticity High-Temperature Equipment Factory developed the “cage format pit resistance furnace energy-saving furnace” (abbreviated as “energy-saving furnace gallbladder”) passed the provincial appraisal in January 1986 and is now being promoted both inside and outside the province. A 75-hole type carburizing resistance furnace of Soviet type was selected as a test in the heat treatment workshop of Luoyang No. 1 Tractor Plant. The furnace body was originally made of heavy clay bricks, the heating element was a spiral resistance wire, and the material was Cr20Ni80. It was placed on a small frame of clay bricks. The external layer of the furnace was insulated with diatomaceous earth powder. The outermost layer was Thin steel plate shell, thermal efficiency test is 6.8% (heat effect
