Flat-plate laser cladding composite alloy layer heater

Abstract

The invention relates to a slab laser cladding compound alloy layer heater which comprises a furnace body, a rolling screen orbit and a thermal insulation rolling screen cover plate. The upper ends of the two sides of the furnace body are provided with the rolling screen orbit where the thermal insulation rolling screen cover plate is arranged in; the two ends of the thermal insulation rolling screen cover plate are respectively fixed on a winding axle that is connected with a synchronous motor; and the synchronous motor is connected with a controller by a lead. A scaffolding is positioned below the thermal insulation rolling screen cover plate and a heating band connected with the controller by the lead is positioned below the scaffolding. The two ends of the furnace body are respectively provided with a thermocouple that is connected with the controller by a compensation lead. The heater satisfactorily solves the problems that two different metals are clad together, and the operation of a laser head is uniform and complete, thus leading to excellent cladding quality, small thermal loss, high efficiency, constant temperature control, low energy consumption, energy conservation, cleanliness and sanitation and no pollution. The heater is applicable to metallurgy industry and equipment manufacturing and repair industry.

Description

technical field [0001] The present invention relates to a heater, specifically a pre-heating device for a high-strength composite layer of two metal materials with different melting points by laser, so as to ensure that the flat laser cladding composite alloy layer of laser cladding is performed at a certain temperature heater. Background technique [0002] With the continuous development of science and technology, the gradual expansion of emerging technologies, laser industrial processing has been continuously integrated into the new processing technology field. While adopting new technology and new methods, the original devices and equipment can no longer meet the new requirements. The requirements of the processing object, such as the high-strength composite layer on the surface of the copper crystallizer in the metallurgical industry in the continuous casting process, originally relied on imports. At present, the coating method is mostly used in China. This method has tw...
