在生产跃进中,本厂承制了一些10吨重以上的鑄钢件。这些大型鑄钢件,在出厂前需要经过一道退火工序。鑄钢件庞大,本厂现有的大台车式退火爐容纳不下。怎么办呢?退火组的工人们以敢想、敢说、敢干的共产主义风格,抛掉了以爐子为主体的退火法,创造了以工件为主体的退火法(或者这样说:打破了大件非得用大爐子处理不可的说法)。这种方法特别适用于大型鑄钢件的热处理,也适用于小型鑄
In the production of leap forward, the factory contracted some of the castings of 10 tons or more. These large steel castings require an annealing process before leaving the factory. A huge cast steel, the existing trolley-type furnace can not accommodate. What should we do? The workers in the annealing group dumped the furnace-based annealing method with the communist style of dare to think, dare to say and dare to do, and created the annealing method with the workpiece as the main body Large bulky furnace must deal with the argument). This method is particularly suitable for heat treatment of large castings, but also for small castings
