为了提高侧埋式盐浴炉的使用寿命,在筑炉时应注意做到下述各方面。一、电极的制造1.电极与电极柄均采用20钢,锻件或厚钢板切割均可。用砖砌坩埚可不用电极柄,电极以矩形截面为宜,尺寸尽可能与砖相配,且要求电极表面平整,以便于砌砖。用耐火混凝土制造坩埚,电极柄最好用圆钢,以减少坩埚开裂倾向。电极柄的截面可按次级电流密度80～100A/cm~2计算确定。2.电极与铜排连接处平面应补焊铜,铜层厚度为5mm,宽度比铜排宽 In order to improve the service life of the side buried salt bath furnace, we should pay attention to the following aspects when building the furnace. First, the electrode manufacturing 1. Electrode and electrode handle are used 20 steel, forgings or thick steel cutting can be. With brick crucible electrode handle can be used, the electrode rectangular cross-section is appropriate, the size matching with the brick, and requires the electrode surface is flat, in order to brick. Made of refractory concrete crucible, the electrode handle is best to use round bar to reduce the crucible tendency to crack. Electrode handle cross section according to the secondary current density of 80 ~ 100A / cm ~ 2 calculation to determine. 2. Electrode and copper connection should be welding plane welding copper, copper thickness of 5mm, the width of the width wider than the copper
