重庆机床厂的“三层三用无烟反射炉”在节约用煤和改善劳动条件方面有显著的效果。这台炉子有两个突出的特点,一个是充分利用余热大大提高了热效率:利用了加热煅件的余热来进行煅造后锻件正火的加热,再利用剩下的余热来烧热水,这就是这台炉子的三个用途。因为充分利用了余热,使热效率达到40%以上;由于利用余热来进行锻件正火加热,在某种程度上可以省去一台炉子。再有一个特点是炉子不冒烟、不冒火、炉门外温度低,彻底改变了原来烟熏、火烤的工作条件。因此,我们认为这台炉子很适合目前我国现场情况,很值得推广应用,特介绍如下,供同志们参考、选用。
Chongqing Machine Tool Plant’s “three-tier three-smoke furnace with no smoke” in the conservation of coal and improve working conditions have a significant effect. This stove has two prominent features, one is to make full use of waste heat greatly enhance the thermal efficiency: the use of the heating waste heat to forging calcined forging normalizing heating, and then use the remaining waste heat to hot water, which This is the three purposes of this stove. Because the full use of waste heat, the thermal efficiency of 40% or more; due to the use of residual heat for forging normalizing heating, to some extent, can save a stove. Another feature is the stove does not smoke, do not run the fire, the furnace temperature is low, completely changed the original smoked, roasted working conditions. Therefore, we think this stove is very suitable for the current situation in our country and is worth popularizing and applying. The special introduction is as follows for reference and selection of comrades.
