我国各工厂用的中小型锻造加热炉,大多数是长方形的直射式炉体结构。这种直射式炉不仅耗能大、烟尘多、效率低,而且在燃烧时炉膛内火焰呈波浪式直冲向炉门外,严重损害工人的身体健康。为此,四川省彭县锦江油泵油咀厂对这种旧式炉进行了技术改造。经过较长时间的反复实践,研制出一种适合我国中小 Small and medium-sized forged furnaces used in various factories in China are mostly rectangular direct-fired furnace structures. This direct-fired furnace not only consumes large amount of energy but also has large amount of smoke and low efficiency. Moreover, the flame in the hearth of the furnace is directly waved toward the outside of the furnace door during combustion, seriously damaging the health of the workers. To this end, Peng County, Sichuan Province Jinjiang oil pump Tsui factory on the old furnace for technological transformation. After a long period of repeated practice, developed a suitable for our country small
