一、结构性能特点结构简图,参见图1。性能特点: 1)炉膛内有非贯通式异型马弗,密封性强,并且节约保护气。该异型马弗有三个开口。一个是另件进口,同时又是排气口。为了使控制气氛密封,除炉内保持正压外,还通过火帘(或气幕)实现炉口密封;另一个开口是出料口,用油或其他帘幕封着;第三个开口是网带返回通道中的网带出口,用 First, the structural performance characteristics of the structure diagram, see Figure 1. Features: 1) There are non-through-shaped chamber muffle, strong sealing, and save the protective gas. The shaped muffle has three openings. One is another import, while the exhaust port. In order to seal the control atmosphere, in addition to maintaining a positive pressure in the furnace, the furnace mouth seal is also achieved by the fire curtain (or air curtain); the other opening is a discharge opening sealed with oil or other curtains; the third opening is Mesh belt back with the network outlet, with
