前言在机器制造业中,热处理是零件加工过程中耗电量最大的工序之一。因此,尽量减少热处理的电力消耗,具有重要意义。为了减少热处理过程中能量的消耗,我们对碳钢在空气炉中进行淬火加热时,加热时间是否有可能缩短,特别是目前所选用的加热系数是否合理等方面做了一些初步试验和探讨。试验结果表明,碳钢在空气炉中进行淬火加热时,加热时间是完全有可能缩短的。一、淬火加热时间的基本含义钢件在热处理加热时,一般来说,必须完成升温、透烧(均温)和组织转变(奥氏
Preface In the machine building industry, heat treatment is one of the most energy-intensive processes in the machining of parts. Therefore, it is of great importance to minimize the power consumption of heat treatment. In order to reduce the energy consumption in the heat treatment process, some preliminary experiments and discussions are made on whether the heating time may be shortened when the carbon steel is quenched in an air furnace, especially whether the heating coefficient is currently selected is reasonable or not. The test results show that the carbon steel in the air furnace quenching heating, the heating time is entirely possible to shorten. First, the basic meaning of quenching heating time Steel heating in the heat treatment, in general, must complete the heating, through burning (average temperature) and organizational changes (austenitic
