Abstract

The invention relates to a double-tower constant-melting-rate protective atmosphere electro slag furnace available for three-station alternate smelting. The double-tower constant-melting-rate protective atmosphere electro slag furnace available for three-station alternate smelting comprises two rotatable tower furnace ends, a mobile smelting station, two auxiliary stations, an electrical system and a PLC (programmable logic controller) and computer control system. The rotatable furnace ends are arranged between the mobile smelting station and the auxiliary stations. Smelting powder main circuits of the rotatable furnace ends are respectively positioned on the mobile smelting station through coaxial positioning cylinders on the upper portions of crystallizer electrodes. The ends of cylinder piston rods of the positioning cylinders are connected with a coaxial return circuit of an electro slag power source. The cylinder piston rods are inserted into four vertical posts below the crystallizer electrodes. The double-tower constant-melting-rate protective atmosphere electro slag furnace available for three-station alternate smelting has the advantages that two small electro slag ingots are obtained in by resmelting on the two smelting stations through two support arms, effective utilization rate of the electro slag furnace and production flexibility are improved, production efficiency is improved, and the difficulty in production of high-tonnage large-diameter long metal electrodes can be overcome.

Description

technical field [0001] The invention relates to a 30t-120t single-electrode double-tower structure three-station alternately smelting constant melting rate protective atmosphere electroslag furnace, which belongs to the technical field of special metallurgical equipment. Background technique [0002] The traditional electroslag furnace is generally composed of a support arm, a column, a short net, a transformer, and a supporting trolley. Clamp the dummy electrode and the metal electrode, and control the transmission device to rotate the T-shaped screw to drive the roller cantilever to move up and down to complete the melting. No inert gas shield is provided. Since there is no inert gas protection, it is difficult to control the hydrogenation of electroslag steel, the burning loss of oxygen, nitrogen and easily oxidized elements. Affect the quality of electroslag ingot. The mechanical friction coefficient of the roller arm type electroslag furnace is large, and the contro...
