一、目前燃煤锻造加热炉的现状根据我国目前实际情况,在锻造加热设备中,燃煤锻造加热炉仍广泛地应用于中、小型工厂中。近年以来,虽然在改炉节煤方面已取得了很大成绩,但也有不少工厂燃煤锻造加热炉的单位煤耗(即煤铁比)仍然较大。有的约为0.7～1公斤煤/公斤锻件,这与先进指标0.3公斤煤/公斤锻件相比,仍有很大的差距。煤炭是工业的粮食,它在四化建设中占有重要的地位。现在世界各国都感到能源不足,所 First, the current situation of coal-fired forging furnace According to the actual situation in our country, forging heating equipment, coal-fired forging furnace is still widely used in medium and small factories. In recent years, although great achievements have been made in coal-saving furnace reform, there are still many units of coal-fired forging furnace coal consumption (ie, coal-iron ratio) is still large. Some are about 0.7 ~ 1 kg of coal / kg forgings, which is still a big gap compared with 0.3 kg of coal / kg forging of advanced indicators. Coal is the grain of industry and occupies an important position in the four modernizations. Now all the countries in the world feel energy deficient
