RJJ井式回火炉

RJ井式回火电阻炉

结构简介

  RJ2系列井式回火电阻炉的主要结构由炉壳、炉衬、炉盖、装料筐、通风机构、升降机构及加热元件等部分组成。

  炉衬由各种耐火材料砌成；炉壳与炉衬之间充填保暖材料；装料筐由不锈钢焊接而成，用作盛放被加热之工件。

  通风机构可促使炉内热空气循环，使温度得到均匀。炉盖升降本系列采用两种结构：25千瓦和35千瓦电炉用杆杆结构：55千瓦和75千瓦电炉用液降升结构。加热元件采用高电阻合金丝绕成螺旋状，并安置在炉衬搁砖上。在炉体的升降轴旁侧装有行程开关，该装置与升降轴联锁。当升降轴升起从而使炉盖打开时，电炉电源切断，以*操作人员的*。

  在炉壳上开有热电偶孔。热电偶与电炉控制柜连接，可测量及控制电炉温度。

  RJ2-XX-6（I）和RJ2-XX-6（II）电炉并装有温度记录仪表和*温保护仪表。

Consructuon Brief:

  Moder RJ2 series pif t*e temper electric resistance furnace maimly consist of furnace linging,furnace cover,wort basket, a*ator,elevting machine and heat elements.

  Furnace lining are bricked with diwersifiedrefractory material;Beteeen furnace shell and furnace lining,filled with insul ating material; work basket is welded with suainess steel to load parts which will be heated.

  A *ator fan could promote hot air circulating to ensure good temperature uriformity;the elevate of furnace door have two t*e;25kW and 35KW are equipped with a leverage mechani*;55KW and 75KW are equipped with a hydraulic mechani*. The heating elements of screw t*e which is made of high resistance alloy wire are mounted on the supporting bricks.

  There are limit switch beside the lifting shaft.This unit is connected with lifting shaft.when the lifting shaft rise to make the furnace cover open, cut down the power supple of the furnace automtically to ensure the operators form danger.

  There are thermocouple hole on the furnace shell, the furnace temperature can be controlled by thermocouple.

  Model Rj2-xx-6(I) and model RJ2-XX-6(II) are equipped with temperature recorder and overtemperature protective instrument.
