结构简介CONSTRUCTION

RX3系列电炉由炉壳、炉衬、加热元件、炉门及控制柜等部件组成。炉衬由0.6的超轻质耐火砖及耐火纤维等砌筑而成；加热元件的由高电阻合金丝绕制成螺旋状，安置在炉膛二侧，炉底后墙及炉门上。被加热工件放在炉膛内的炉底板上，炉门的升降是通过手摇链轮或机械传动来进行的，在炉门上部装有一行程开关，当炉门开启时，电炉电源即被切断，以保证操作人员的安全。另在炉顶上设有二支热电偶，一支作为检测炉温用，另一支作为超温保护用。

This RX3 series furnace consists of casing, lining, heating dlements,door and control .The lining is built with 0.6 over lightweight refractory brick and refractory fiber. The heating element is screwed up by high resistance alloy wires and installed on the hearth’s two sides, the rear wall of the furnace bottom and the furnace door. The heated workpieces are placed on the furnace hearth plate inside the chamber. The door lift is operated with manual sprocket wheel or mechanical transport. On top of the furnace door is provided with a position switch. The furnace door opened, power supply is immediately cut off to ensure operator’s safety. Two thermocouples put on top of the furnace.
