Abstract

The present invention relates to a metal material surface electroslag quick-equally heating and combination equipment. It is formed from equally-heating device, melting device and intercommunication device. It is characterized by that said intercommunication device is respectively connected with melting device and equally-heating device. Said invention is simple in structure, and can be used for producing various composite workpieces with several shapes.

Description

technical field [0001] The invention relates to a rapid and balanced electroslag heating and compounding device on the surface of metal materials. Background technique [0002] The development of modern science and technology has put forward higher and higher requirements for the composite properties of materials. For example, in the field of steel rolling, the application of new rolling technologies can effectively improve the quality of rolled materials, but at the same time, it also affects the wear resistance of rolls, Higher requirements are put forward for strength and toughness. Metal heating and compounding technology is a key technology in metal material compounding technology, which directly affects the success or failure of metal material compounding and the quality of compounding. In the fifth issue of May), the development of composite roll manufacturing technology at home and abroad is disclosed. The main composite methods are: 1. Centrifugal casting method; 2...

AI Technical Summary

Problems solved by technology

The main problems in the above-mentioned method are: 1. When the composite layer contains metal elements with large density differences such as tungsten, chromium and vanadium, when the centrifugal casting method is used, segregation is easy to occur and seriously affects the quality of the roll; 2. The induction of the CPC method device The heating speed is slow, and the compounded metal needs to be refined, otherwise it will not have the pure structure of the electroslag casting method; 3. In the rotary electroslag casting method, the compounded metal needs to be made into a tubular shape, which is expensive, and the tubular self-consumable electrode The high-temperature zone formed during melting in the slag pool can make the surface of the roller core heated and recombined, but the temperature of the roller core surface changes greatly during the melting and casting process and is difficult to control; 4. The hot isopressing process requires large-scale powder-making equipment, high-temperature equipment, High pressure equipment and vacuum equipment, large investment and high cost
