加热炉是锻造车间的重要设备,它的结构和技术性能的高低、直接关系到锻件的质量、生产效率、劳动强度、能源利用、使用寿命、环境污染、文明生产等许多方面。目前国内锻造加热工艺,一般还采用火焰加热炉。火焰炉按其使用燃料不同,又分为油炉、煤气炉和直接燃用煤炭的加热炉。在整个比例中,后者又占了大多数。燃煤加热炉又因我国煤炭资源丰富,一般可就地取材、来源方便可靠,建造投产也比较快,同时也有一定的使用经验,因此为许多中、小型机械工厂所广泛采用。我国煤炭蕴芷丰富、品种繁多,但质量也因地而异,优劣相差较大。因此不但要使加热 Heating furnace is an important equipment for forging workshop, its structure and technical performance level, directly related to the quality of forgings, production efficiency, labor intensity, energy use, service life, environmental pollution, civilized production and many other aspects. Currently forging heating process, the general also used flame furnace. Flame furnace according to their use of different fuels, and is divided into oil furnace, gas furnace and directly burning coal furnace. In the entire proportion, the latter accounted for the majority. Coal-fired heating furnace because of China’s rich coal resources, generally available on the spot, the source is convenient and reliable, the construction is also relatively fast production, but also have some experience in the use, and therefore for many medium and small machinery factory widely used. Yun-rich coal in our country, a wide variety, but the quality varies from place to place, the difference between good and bad. So not only to heat up
