许多机械零件需装在托盘或料筐内做热处理,圆形炉膛是比较适用于这种热处理方式的炉型,在一些国家正逐渐普及应用。一、圆形炉膛的特点 1.加热均匀:物料在炉内主要是通过辐射和对流加热。由于圆形炉膛没有象矩形炉膛那样的死角,因此物料能受到炉壁和炉气均匀的辐射热。另外,不论采用辐射管加风扇或是烧嘴的加热方式,由于没有死角,使对流加热也更加均匀。
Many mechanical parts to be installed in the tray or baskets for heat treatment, circular hearth is more suitable for this type of heat treatment furnace, in some countries is gradually gaining popularity. First, the characteristics of a circular furnace 1. Heating evenly: the material in the furnace is mainly by radiation and convection heating. Since the circular hearth is not as dead as the rectangular hearth, the material is exposed to radiant heat evenly from the furnace walls and the furnace gas. In addition, regardless of the use of radiant tube fan or burner heating, due to no dead ends, the convection heating is more uniform.
