Rotary Kiln Tire and Roller Fracture Repair Technology

Abstract

The invention discloses a process for repairing the breakage of a rotary kiln tyre/roller, comprising the following steps of: performing fixed connection at the two sides of a crack, cutting out a U-shaped crevasse, grinding, sequentially depositing a binding layer, a transition layer, a work layer and a processing layer at the crevasse, dismounting a fixing plate, and carrying out overall grinding and polishing. The process for repairing the breakage of the rotary kiln tyre/roller provided by the invention is low in repairing price, which is only 100,000-1500,000 Yuan, low in investment, simple in process, convenient to operate, easy to learn and grasp, novel in technology, low in cost, and practical and reliable; therefore, the process not only increases income and reduces expenditure for the country but also makes an enormous contribution to consumption reduction and energy conservation as well as resource conversation and efficiency improvement for an enterprise.

Description

technical field [0001] The invention relates to a process for repairing the fracture of a rotary kiln tire and supporting roller, which is widely applicable to industries such as cement plants, power plants, pelletizing plants, chemical plants, smelting plants, compound fertilizer plants, and ceramics. Background technique [0002] At present, the broken tires and rollers cannot meet the repair needs in terms of technology, technology, and materials. It is difficult and valuable, which directly affects production. There is no repair method at home and abroad, so they have to be replaced directly. The loss is huge and affects production; mainly The problem is: it is difficult to control the strength level of cracks and deposited metals, materials, processes, and technologies, which can easily cause welding cracks in the weld, cracks in the edge of the weld and the substrate, and cracks in the deposited area are difficult to control, and it is at least to change a tire 50 mill...

Problems solved by technology

[0002] At present, the broken tires and rollers cannot meet the repair needs in terms of technology, technology, and materials. It is difficult and valuable, which directly affects production. There is no repair method at home and abroad, so they have to be replaced directly. The loss is huge and affects production; mainly The problem is: it is difficult to control the strength level of cracks and deposited metals, materials, processes, and technologies, which can easily cause welding cracks in the weld, cracks in the edge of the weld and the substrate, and cracks in the deposited area are difficult to control, and it is at least to change a tire 50 million yuan, including maintenance fees, dismantling refractory bricks, docking, hoisting, kiln calibration, refractory brick laying, etc. It takes 28 days, and a direct economic loss of 1 million yuan per day is required. It can be seen that the cost is huge. How to solve this problem, It is the main subject of this process, technology and material
