在全国各地的中小型锻造厂和锻造车间里,有大量烧煤的锻造加热炉。其中,有不少锻造加热炉普遍存在着耗煤量大、热效率低、烟尘严重、操作条件差等缺点,这与当前消除环境污染、节约能源是很不适应的。为了解决这一问题,很多工厂不断地对锻造加热炉进行改造,建造了不少节煤、无烟、操作方便的新型锻造炉。上海汽车发动机厂建造的往复式消烟、除尘、节煤锻造炉就是其中的一种。它是在无烟反射炉基础上通过不断改革而成功的。此种锻造炉与一般无烟反射炉比较,有下列的优点:烟尘浓度下降70％;煤耗下降了20％;还能充分利用余热;并能减轻劳动强度。
In all over the country forging small and medium-sized forging workshops and forging shop, there are a large number of coal forging furnace. Among them, there are many forging furnace widespread coal consumption, low thermal efficiency, serious smoke, poor operating conditions and other shortcomings, which with the current elimination of environmental pollution, energy conservation is not suited. In order to solve this problem, many factories continue to reform forging furnace, built a lot of coal, smoke-free, easy to operate new forging furnace. Shanghai Automotive Engine Factory built reciprocating smoke, dust, coal forging furnace is one of them. It is successful on the basis of continuous reform in the smoke-free furnace. Compared with the general smokeless reverberatory furnace, the forging furnace has the following advantages: the concentration of soot is reduced by 70%; the coal consumption is reduced by 20%; the waste heat is also fully utilized; and the labor intensity can be reduced.
