本文主要对新型保温材料如碳毡、碳布和硅酸铝纤维等制成的厚壁炉衬的真空电阻炉的功率计算进行介绍。重点是对炉衬热损失计算方程式求解进行了讨论。方程式求解有两种方法,其中用图解法比较简便。一、新型保温炉衬近年来一些新型保温材料不断出现,如碳毡、碳布、硅酸铝纤维等。它们的保温性能好,耐高温,热惯性小;含气量少,容易抽真空。这些材料用在真空电阻炉中作为厚壁保温
This paper mainly introduces the calculation of the power of the vacuum resistance furnace with thick lining made of the new insulation material such as carbon felt, carbon cloth and aluminum silicate fiber. The key point is to discuss the calculation of the heat loss of the lining. There are two ways to solve the equation, which is easy to use graphical method. First, the new insulation lining In recent years, some new insulation materials continue to appear, such as carbon felt, carbon cloth, aluminum silicate fibers. Their thermal insulation properties, high temperature, thermal inertia is small; less gas, easy to vacuum. These materials are used in thick-walled insulation in vacuum resistance furnaces
