我厂过去红装大托轮(水泥厂旋窑上用的,直径1公尺多,重2吨多),是将托轮放在退火炉中加热,有时也用焦炭包住托轮加热,操作都很困难,温度不易控制。现在由工人同志改用如附图的方法,在地上掘一个500公厘深的坑,上面放两条钢轨,把托轮平放在钢轨上,就可在轮辐间的八个孔里放进焦炭来加热,为了使加热快,可以在每个孔上加一节烟囱,孔下边放几根铁棍作炉条。迭样全部只要五个小时左右,即可加热和红装完毕。
In the past, our factory had a large red wheel (cement plant rotary kiln, more than 1 meter in diameter, weighing more than 2 tons). It was heated in an annealing furnace and sometimes coke wrapped with rollers to heat and operate Very difficult, the temperature is not easy to control. Now, as the workers’ comrades have switched to the method as shown in the attached figures, they dig a 500-mm-deep pit on the ground, place two rails on top of each other and lay the support wheels on the rails so that they can be placed in the eight holes between spokes Coke to heat, in order to make the heating fast, you can add a chimney in each hole, holes below the hole to put a few iron bars. Like all the aliases for about five hours, you can heat and red loaded is completed.
