前言目前,我国小型企业轧钢车间里的炉子设施,主要是旧社会遗留下来的,其绝大部份采用烧煤的加热炉;中型企业已逐步过渡到采用热发生炉煤气;大型企业及苏联援助建设的企业则主要是采用高压净煤气为燃料。从加热炉的发展过程看来,这是生产逐步近代化的演变。根据目前我国勤俭建国的方针,烧煤和烧热发生炉煤气的炉子在相当长的一段时期内,仍将继续使用,尤其是烧煤炉子,现在和将来都将广泛采用。本文拟对烧煤加热炉、烧热发生炉煤气的加热炉和净煤气加热炉的工作,分别作初步的评价,并提出我们对这些炉子的改进意见。
Foreword At present, most of the furnace facilities in the rolling mill of small enterprises in our country are left over from the old society. Most of them use coal-fired furnaces. Medium-sized enterprises have gradually shifted to the use of hot-blast furnace gas. Large enterprises and Soviet aid The construction of the enterprise is mainly the use of high pressure net gas as fuel. It seems from the furnace development process, which is the evolution of the gradual modernization of production. According to the principle of building a thrifty nation in our country, the stoves for coal-fired and heat-producing producer gas will continue to be used for a long period of time, and coal burning stoves in particular will be widely adopted now and in the future. This article intends to make a preliminary assessment on the operation of the coal-fired heating furnace, the heating furnace of the heat-producing furnace gas and the net gas heating furnace, and puts forward our suggestions for improvement of these furnaces.
