Description

Reusable roller

Technical Field

The utility model relates to a roll technical field specifically is a can used repeatedly roll.

Background

The rolls are important components of rolling mills and are mainly used as main working parts and tools for continuous plastic deformation of metals. China began to produce casting rolls in batches from the 30's of the 20 th century, but the varieties were rare. The first specialty roll mill in China was built by the North Schchen platform in the last 50 s. The Anshan iron and steel company was first internationally tried in 1958 and used 1050 large ductile iron rolls for roughing. Successfully cold-rolled work rolls and large forged steel rolls were manufactured successively in the 60 s. The taiyuan iron and steel company and the Beijing general iron and Steel research institute of the last 70 years together trial-manufacture centrifugal cast iron rolls for a steckel mill and a hot continuous rolling wide strip steel unit, and the chen table metallurgical machinery roll company Limited tries to manufacture semi-steel work rolls for a power hot wide strip steel mill and work rolls for a cold rolling wide strip steel mill. In 80 years, Chinese successively developed new varieties of large forged steel supporting rollers, forged semi-steel and forged white cast iron rollers, powdered tungsten carbide roller rings, high-chromium cast iron rollers and the like. In the 90 s, the roller production in China basically meets the domestic requirements and has some export, but the variety needs to be increased and the quality needs to be improved.

The roller belongs to a vulnerable part in the actual use process, the surface is worn after long-term use, the roller cannot be used and needs to be replaced, and a large amount of resources are wasted, so that a roller which can be repeatedly used is needed to replace the roller which is used at present, for example, the roller which can be repeatedly used disclosed by Chinese utility model CN201721026381.6, the purpose of being disassembled and repeatedly used is achieved mainly through the matching between a key groove and a lock disc, but the roller can generate a large amount of heat in the actual use process, so that the roller expands due to stress generated by overheating, the key groove becomes small, a key fixed on the lock disc is tightly clamped and is difficult to pull out, the roller can be continuously used after being cooled for a long time, the waste of time is caused, and the purpose of reducing the production cost cannot be achieved, therefore, a novel roller which can be repeatedly used is provided, to solve the above-mentioned problems.
