阳极环的焊接难点分析与解决方法

Analysis and Solution of Welding Difficulties of Anode Ring

直流电弧炉是指用直流电作为能源的电弧炉。它与交流电弧炉一样,利用电极和炉料(或熔池)间产生的电弧来发热,从而达到熔炼的目的。直流电弧炉可用来熔炼钢或合金以及有色金属。阳极环由低合金钢本体和三个由低合金钢板/紫铜连接板/紫铜连接管焊接而成的组合件构成。组合件中的低合金钢板/紫铜连接板起着对紫铜管的强度支撑作用,紫铜连接板/紫铜连接管用于对阳极环进行冷却。某公司的直流电弧炉翻修项目中,需要制作位于的直流电弧炉底部的阳极环,但是期焊接较难,本文依据此项目分析阳极环的焊接难点与解决方法。

DC arc furnace is an arc furnace which uses DC as energy.It is similar to AC arc furnace,and uses the arc generated between electrode and furnace charge(or molten pool)to heat,so as to achieve the purpose of smelting.DC arc furnaces can be used to melt steel or alloy and non-ferrous metals.The anode ring is composed of low alloy steel body and three assemblies welded by welding low alloy steel plate/copper connecting plate/copper connecting pipe.The low alloy steel plate/copper connecting plate in the assembly plays a strong role in supporting the copper pipe,and the copper connecting plate/copper connecting pipe is used to cool the anode ring.In the renovation project of DC arc furnace in a company,the anode ring at the bottom of DC arc furnace needs to be made.However,it is difficult to weld in the period.This paper analyzes the welding difficulties and solutions of anode ring according to this project.
