Description

Technical Field

[0001] The invention relates to special equipment in a steel strip production process, in particular to special equipment for numerically controlled steel strip mirror polishing. Background Art

[0002] Steel belt is a high-quality material used as a conveyor belt. Its strong but soft characteristics can be used as equipment for different industrial production processes. In addition, its smooth surface can contact many different types of substances, so it can more effectively cooperate with processing operations of different natures and has a wide range of applications. Steel belts are resistant to high and low temperatures and are suitable for environments ranging from -50 degrees to 250 degrees. They can also transport high-temperature items that rubber and resin conveyor belts cannot carry. They can also complete heating operations and bake, roast, steam, and boil food. Moreover, they can be washed with high-temperature steam and can also be used in freezers. Even at low temperatures, the steel belt will not deform and is suitable for continuous freezing operations of food in cold storage.

[0003] Steel belts will be rough, scratched, etc. during use, so generally steel belts need to be repaired every 3-6 months. The main equipment for repair is grinding and polishing the steel belts. The existing market polishing equipment is replaced by wood polishing machines. Wood polishing machines use sanding belts for polishing and have high power consumption (normally about 100kw), large sanding belt consumption, high noise during polishing, and serious pollution of coolant.
