Vacuum consumable electric arc furnace smelting and recycling
Generally, electrodes with a certain strength need to be prepared first to prevent pieces from falling off during the smelting process. The four commonly used electrode preparation methods are:
(1) Fully mix the chipped return charge or small-sized block return charge with sponge titanium and alloy elements, press it into an electrode block on a hydraulic press, and then weld it into a consumable electrode. This is a vacuum consumable arc furnace Golfa is the most commonly used method for recycling return charge, and the addition ratio of return charge can reach 40%.
(2) The returned charge of the same brand is bundled in a certain proportion to form self-consumption power f and the added amount of returned charge can reach 100%.
(3) The electrode block is used as the core material and is surrounded by a certain proportion of plate and tubular return charge to form a consumable electrode. The amount of return charge can be less than 80%.
(4) Consumable electrodes are made from ingot risers of the same brand and specifications through plasma argon arc welding, and the utilization rate of returned charge is 100%.
