Abstract

The invention relates to the technical field of metallurgy industry steeling rolling equipment, in particular to a looper roll used for rolling altitude bars and wire rod material equipment and a production method thereof. The looper roll comprises a looper roll body, the looper roll body is provided with arc-shaped grooves, the outer circumferences of the arc-shaped groove is provided with lasercladding layers, and the laser cladding layer are completed by adopting a laser cladding technology and a laser quenching technology. According to the looper roll, by adopting a novel production manufacturing method and a novel thermal processing manner, the surface hardness of the looper roll is wear resistant and reliable, repeated repairing and recycling can be conducted in subsequent production of the laser cladding layers, namely, using, wearing, cladding, quenching and recycling are conducted in sequence.

Description

technical field [0001] The invention belongs to the technical field of steel rolling equipment in the metallurgical industry, and in particular relates to a looper roll used for rolling high-gauge rods and wire rod equipment and a manufacturing method thereof. Background technique [0002] There are two types of loopers in rod and wire rolling equipment, horizontal loopers and vertical loopers. Among them, the looper roller is a common part, and its structure diagram is shown in figure 1 In order to achieve the output of rolled steel, many manufacturers mostly use cemented carbide material, which has high price and cost, long production and processing cycle, complicated process and large consumption. Usually, the improvement method uses GCr15 bearing steel material instead of cemented carbide material to reduce material cost. However, because the material itself is too hard, although more annealing processes are carried out, the processing is difficult (drilling and tapping...
