Technical Field

[0001] The utility model relates to the technical field of roller surfacing heat treatment, in particular to a convenient roller surfacing repair heating device. Background Art

[0002] Roller cladding is a commonly used metal surface repair technology that deposits wear-resistant alloys on the surface of the roll to improve the wear resistance and service life of the roll. As an important component of rolling equipment, the roll is subjected to huge pressure and friction, and is prone to wear and cracks, which affects the rolling quality and efficiency. Therefore, the application of roll cladding technology is of great significance.

[0003] After the roll surfacing, it is usually necessary to put the roll into a heating furnace for stress relief treatment. For example, the roll surfacing heating furnace disclosed in patent CN208869623U uses a placement frame to fix the roll, and then the upper and lower split furnace bodies are buckled together, and then the roll is heated by resistance heating. However, this operation method is time-consuming and labor-intensive, and the roll needs to be hoisted and positioned. The roll is generally made of cast iron, cast steel, forged steel or special steel, and weighs from a few tons to dozens of tons. Therefore, the hoisting process of the roll is a very cumbersome and dangerous process. Therefore, this traditional roll heating method needs to be improved. Utility Model Content
