Sintering belt cooling pallet and repair method thereof

Abstract

The invention relates to a sintering belt cooling pallet. The left end and the right end of a base plate are respectively welded with a connecting plate, wherein the connecting plates and the base plate are positioned in the same plane, the weld at the right end of the base plate is positioned at the right side of a right assembly plate, and the weld at the left end of the base plate is positioned at the left side of a left assembly plate. The invention also relates to a method for repairing the sintering belt cooling pallet, which comprises the following steps: (1) cutting off the deformed connecting plate along the weld; (2) processing and manufacturing a new connecting plate based on the size of the original connecting plate; (3) making a posterior-anterior 2mm-depth groove in the middle of the new connecting plate, and cladding tungsten carbide alloy in the groove; (4) splicing and welding the new connecting plate and the base plate; (5) processing the welded connecting plate and the base plate to restore the size of the original drawing; and (6) and carrying out surface inspection on the weld. The invention has the advantages of simple structure, low repair cost and long service life.

Description

(1) Technical field [0001] The invention relates to a sintering belt cooling trolley and a repair method thereof. (2) Background technology [0002] At present, the sintering belt cooling trolleys used in the sintering plants of iron and steel enterprises are mainly damaged in the form of severe wear and deformation of the connecting bottom plates on both sides during use. Normally, they cannot be repaired. They have to be scrapped as a whole. The service life is about 3-4 years During the period, the equipment costs about 30,000 yuan, and each sintering production line is about 4 million yuan. It is impossible to replace a single one. If all of them are replaced, the cost will be higher. In normal use, the connection plate of the bottom plate, which is the load supporting part with a cooling trolley, is easily worn and deformed by the sintered material and its own weight and the wear of the sprocket, which makes the equipment unable to work normally. operation, and prone ...

Problems solved by technology

[0002] At present, the sintering belt cooling trolleys used in the sintering plants of iron and steel enterprises are mainly damaged in the form of severe wear and deformation of the connecting bottom plates on both sides during use. Normally, they cannot be repaired. They have to be scrapped as a whole. The service life is about 3-4 years During the period, the equipment costs about 30,000 yuan, and each sintering production line is about 4 million yuan

Cannot be replaced individually, if all of them are replaced, the cost will be higher

In normal use, the connection plate of the bottom plate, which is the load-bearing part with a cooling trolley, is affected by the sintered material and its own weight and the wear of the sprocket, which is easily worn and deformed, which makes the equipment unable to work normally. operation, and is prone to equipment accidents
