推杆炉的特性

依靠推料机，将放在轨道上的炉料或料盘周期性地推入炉内或推出炉外。工件在炉内进行加热时保持一定时间的相对静止状态；出炉淬火时，有的是料盘自动倾斜后将炉料倒入淬火介质中，有的是料盘与炉料一起进入淬火介质中冷却。

这类炉子对不同热处理工艺的适应性较强，因此便于组成生产线，广泛应用与淬火、正火、退火、回火和渗碳、渗氮及碳氮共渗等热处理工序。

Characteristics of pusher furnace

Depending on the pusher, the charge or charge tray placed on the track is pushed into or pushed out of the furnace periodically. When the workpiece is heated in the furnace, it is kept in a relatively static state for a certain period of time; when the workpiece is quenched out of the furnace, some of the materials are poured into the quenching medium after the material pan tilts automatically, and some of the materials are cooled in the quenching medium together with the material pan.

This kind of furnace has strong adaptability to different heat treatment processes, so it is convenient to form a production line and widely used in quenching, normalizing, annealing, tempering, carburizing, nitriding, carbonitriding and other heat treatment processes.
