平锻机床身拉紧螺栓热装时的加热方法有:火焰加热法(氧乙炔或煤气加热)、电阻加热法、电感应加热法等。我厂在加热ГКМ2000平锻机之纵向拉紧大螺栓(Ф280×5000)时,采用了电感应加热法。实践证明这是一种较理想的方法。采用这种方法只需要一台或几台电焊机、几十米粗导线和几张绝热用的橡胶石棉板就可以了。这些东西一般的工厂都有。我们在加热ГКМ2000平锻机的拉紧螺栓时,使用了两台16 Flat forging machine tools to tighten the hot-bolt heating methods are: flame heating (oxygen acetylene or gas heating), resistance heating method, induction heating method. I plant heating ГКМ2000 flat forging machine longitudinal tension bolt (Ф280 × 5000), the use of induction heating method. Practice has proved that this is a more ideal method. This method requires only one or several welding machines, tens of thick wire and a few adiabatic rubber asbestos on it. These things are generally factory. We used two 16s to heat the ГКМ2000 flat tightening bolt
