Hot plasma casting roller repairing device and method

Abstract

The invention provides hot plasma casting roller repairing device and method, relates to the technical field of metallurgical engineering, and solves the technical problems of time and energy consumption, high cost and low efficiency. The roller repairing device comprises a melting system and a casting system for conveying and connecting materials, a plasma heating system, an auxiliary system, a walking device and a lifting device, wherein the melting system is arranged on the walking device; and the heating system is movably connected with the walking device through the lifting device, so that the heating system can lift up and down in the vertical direction relative to the melting system. According to the hot plasma casting roller repairing device and the method provided by the invention, the materials used for plasma melting roller repairing are adopted and can be quickly heated and melted into a liquid state, so that the energy and the materials are saved, and the repairing cost isreduced; the labor intensity is reduced, the automation degree is improved, and the working environment is improved; the repairing period is shortened, the enterprise burden is reduced, and the utilization ratio of equipment and fund is improved; and large-scale, batched, serial and automatic repairing can be realized.

Description

Technical field [0001] The invention relates to the technical field of metallurgical engineering, in particular to a hot plasma casting and repairing roll equipment and method. Background technique [0002] Rolls are important parts of rolling mills in rolling mills. They use the pressure generated by a pair or a set of rolls to roll steel. They are mainly affected by dynamic and static loads, wear and temperature changes during rolling. The roll includes a core (also called a roll core, including a roll shaft and a roll neck) and an outer layer of the roll body (also called an outer layer or a working layer) coaxially arranged outside the core. The outer layer and core of the composite roll are made of different materials, and the two materials are metallurgically combined. The outer layer of the roll body is the working layer and the outer surface is the roll surface. The roll can meet the wear resistance of the roll body , Thermal fatigue resistance and other performance requ...
