Description
Technical Field
The invention relates to a circulating roller surfacing mechanism and a roller surfacing method thereof, belonging to the technical field of roller welding.
Background
The roller is an important part on a rolling mill in a steel mill, is usually damaged in the using process and needs to be repaired, the weight of the roller is dozens of tons to one hundred tons generally in the large-scale roller repairing process, the diameter of the roller can reach 2 meters, the roller repairing process mainly comprises the step of surfacing welding the surface of the roller, and the biggest problem is that the surfacing welding time is long, the number of joints is large, and the product quality is influenced. At present, the roller rotates in the surface overlaying process of the roller, a welding head on a special roller overlaying machine travels along the axial direction of the roller to enable the overlaying track to be a spiral track, after one layer of overlaying is finished, the welding head resets and then overlays the next layer of wear-resistant metal, a layer of wear-resistant metal is continuously and uniformly overlaid on the surface of the roller, the overlaying of one large roller usually needs two months or three months, and the roller needs to be subjected to heat treatment to release stress after the overlaying is finished each time.
An existing special roller surfacing welding machine, such as the special roller surfacing welding machine disclosed in chinese patent CN201310619612.4, generally has a cross beam with two ends provided with columns, a welding head is disposed on the cross beam and located at the upper end of a heating furnace, and one special surfacing welding machine corresponds to one heating furnace, so that a roller can be heated, insulated and welded at the same time. However, when the special roll surfacing welding machine is used for welding large rolls, a plurality of welding heads are required to work on line at the same time, and each welding head is only responsible for welding and repairing products in the area. Although a single welding head can meet the use requirement of welding position adjustment in the area in which the single welding head is responsible, the welding head can only walk on a linear guide rail of a cross beam, after the welding process of the layer in the area is completed, the welding head needs to return to the starting point of the area, and the reciprocating skip welding causes more joints of each layer on one hand, and on the other hand, the product quality can be effectively ensured when a plurality of welding heads synchronously complete the welding, when one welding head breaks down, because the welding head is responsible for the limitation of the area, other welding heads can not reach the area for repair welding, and only the fault recovery can be waited, or other welding heads are responsible for the completion of the area task, and enter the area for repair welding, so the construction period is prolonged, heat supply is continuously carried out on a roller during the repair welding, and the energy and artificial resource waste is large. In addition, the existing special roller surfacing welding machine is in one-to-one correspondence with the heating furnace, so that only one station of rollers can be welded at a time, and the special roller surfacing welding machine is in an idle state in the time of finishing heat treatment of surfacing welding each time, so that the effective utilization rate of equipment is reduced, and the production efficiency is low.
