When it is used as coating of iron pan,the efficiency of heat transmission of enamel coated pan increases about 20 % than that of uncoated one.
用该红外搪瓷制成的搪瓷铸铁锅,其传热效率比不涂搪瓷的铸铁锅提高20%,且抗冲击韧性和耐温急变性分别达到0。
On the basis of the test results of a full scale hot state explosion test a calculation and analysis was conducted of the explosion pressure of the following: square box test parts, nodular cast iron boiler, grey cast iron boiler and grey cast iron boiler plates.
基于一次大规模热态爆破试验的结果 ,分别对方箱试件、球墨铸铁锅炉的爆破压力、灰口铸铁锅炉和灰口铸铁锅片的爆破压力进行了计算和分析 ,得出安全系数选取的推荐值。
