Roller cladding heating kiln

Abstract

The invention relates to a roller cladding heating furnace which comprises a furnace body, a heating band, an insulating layer and a powder receiving pan. The furnace body is provided with a right furnace box and a left furnace box which are in a mutual butt joint way; the upper cover of the furnace body is provided with a laser operation window; the inner wall of the furnace box is provided with the insulating layer; the inner circle of the insulating layer is provided with the heating band; and the upper part in the furnace box is provided with the powder receiving pan that is fixedly connected with the inner wall of the furnace box. The side of the furnace box is provided with a temperature detecting point and is connected with the temperature control input end of a controller. Or a plurality of furnace bodies are in head-to-tail connection to form a long furnace body. The furnace has excellent cladding quality, little thermal loss during the cladding process, simple structure, flexible assembly, high efficiency, constant temperature control, low energy consumption, energy conservation, cleanliness and sanitation and no pollution. The furnace is applicable to roller manufacturing industry.

Description

technical field [0001] The invention relates to a heater, in particular to a roll cladding heating kiln for constant temperature heating and cladding of a hard surface alloy layer of a flat roll and a shaft workpiece by using a laser. Background technique [0002] With the continuous advancement of science and technology and the gradual expansion of laser application fields, traditional process equipment can no longer meet the requirements of new processes and new processing objects. For example, hard surface cladding for high-strength shaft workpieces such as rolls is a typical For example, the current cladding method often has two phenomena due to the different materials of the two metals. One is that the strength of the alloy layer on the hard surface of the roll is not good enough, and cracks are prone to appear after a long time. The other is that the uniformity of the alloy layer is relatively low. Poor, its thickness can not do as one likes. With the rapid developmen...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a method that can not only heat roller shafts of different lengths and different roller diameters, but also perform laser cladding at the same time, aiming at the practical problem that two different metals are not easy to melt and cast due to different melting points. The device solves the cracking problem of roll cladding during hard surface cladding, and creates a roll cladding heating furnace with good conditions for roll repair and hard surface composite technology
