热处理工艺过程所需的工夹具,过分强调坚固耐用从节能角度看是不适当的。实践中我们得出:一个合理的工夹具应在保证强度的情况下,重量越轻越好,这样可大幅度减少工夹具本身吸热所需的热能,达到节能目的。例如,我车间高速钢回火筐,改进前是长方形回火筐,用6毫米厚钢板钻孔后焊接而成(见图1), Heat-treatment process required for the fixture, overemphasis on durability from the energy point of view is not appropriate. In practice, we come to a conclusion: a reasonable fixture should be under the condition of ensuring the strength, the lighter the weight, the better, which can greatly reduce the thermal energy required by the fixture itself to absorb heat and achieve the purpose of saving energy. For example, my workshop high-speed steel back to the fire basket, before the improvement is a rectangular tempering basket, with 6 mm thick steel plate welded after welding (see Figure 1)
