Abstract

The invention relates to an electroslag remelting furnace. The invention aims at providing to an electroslag remelting furnace with which three-phase power supply is adopted. With the electroslag remelting furnace, double arm electrodes are replaced in turn, and the double arms work alternately. The electroslag remelting furnace comprises an elevation platform and a platform elevation device used for driving the elevation platform to move up and down. A motorized flatcar is arranged on the elevation platform. A crystallizer is arranged on the top of the motorized flatcar. Two columns are arranged beside the platform elevation device. A cross arm is arranged on the upper part of each column. The cross arms and the columns are connected through connection devices. The connection device comprises a rotation device which can drive the cross arms to rotate around the axes of the columns, and an elevation device which can move along an axial direction of the columns. Fixture heads used for fixing electrodes are arranged at free ends of the cross arms. The electroslag remelting furnace has the advantages that: network load is balanced, and interference is low; electroslag ingot uniformity and compactness are improved; the furnace is suitable for the productions of large-tonnage and large-size metal materials, especially electroslag ingots with 10-150 tons, which are used in high-end large forgings such as nuclear power main pipes, reactor internals, ultra-supercritical rotors, and the like.

Description

technical field [0001] The invention relates to electroslag smelting equipment, in particular to an electroslag remelting furnace. Background technique [0002] The high-parameter and large-capacity development of major equipment such as energy engineering, petrochemical engineering, and metallurgical engineering has made the quality and performance requirements of large forgings increasingly high, and the metallurgical quality of steel ingots is the basis and prerequisite for obtaining large forgings. play a key role in. The value of large forgings is huge, and one piece is worth millions or even tens of millions of yuan. The electroslag technology has the functions of strong refining and purification and controllable rapid solidification. The electroslag ingot has a pure texture, less inclusions and fine dispersion, uniform composition with small segregation, compact structure and no solidification defects such as loose shrinkage cavities. Electroslag remelting method Th...
