Description

Technical Field

[0001] The invention relates to the field of hot rolling mill roller cleaning, and in particular to a multifunctional quick cleaning all-in-one machine for hot rolling mill rollers. Background Art

[0002] The hot rolling mill has a huge number of transmission rollers. During the production process, the roller surface will have problems of aluminum sticking and dust and oil attached, which will directly cause surface defects of the product and require cleaning, polishing and protective oiling.

[0003] In terms of cleaning and grinding, the main purpose is to repair defects such as wear and scratches on the roller surface. Usually, professional grinding equipment is used, such as a handheld grinder. When grinding, attention should be paid to ensuring the flatness of the roller surface and grinding evenly in a certain direction. During the grinding process, because the defects on the roller surface must be carefully handled to ensure flatness, especially for the longer rollers of large hot rolling mills, the staff needs to spend a lot of time using the grinding equipment to operate little by little. And if the defects are more and more serious, repeated grinding is required, which undoubtedly increases the input of manpower. Seriously affect production efficiency and product quality.

[0004] At the same time, oiling the surface of the hot rolling mill rollers plays an important role. First of all, oiling can play an anti-corrosion function. There are factors such as water vapor in the hot rolling environment that can easily cause the rollers to rust. The protective oil can form a protective film on the surface of the rollers, isolating oxygen and water vapor, slowing down the corrosion process, and extending the service life of the rollers. When oiling the hot rolling mill rollers, it is generally applied manually with a brush. During the oiling stage, in order to ensure a uniform oil film and sufficient coverage area, it is often necessary to apply or spray multiple times, especially for large rollers. The entire oiling work will last for a long time. This method is suitable for local oiling or small rollers, and can more accurately control the application position and amount of oil, but the efficiency is low. Summary of the invention

[0005] In order to solve the problem that the existing hot rolling mill transmission rollers are huge in number, aluminum sticking and dust and oil will be attached to the roller surface during the production process, and a large amount of manpower and time are consumed during the cleaning, grinding and protective oiling of the hot rolling mill rollers, which seriously affects the production efficiency and product quality.
