Processing technology for recycling hot-rolled aluminum plate mill roll

Abstract

The invention relates to a processing technology for recycling a hot-rolled aluminum plate mill roll. The processing technology comprises the following processing steps: selecting the used hot-rolled aluminum plate mill roll as a mother mill roll; roughly processing and quenching a roll sleeve; spraying the outer circle of the roll sleeve by high-pressure water spray, cooling and quenching; spraying the inner circle of the roll sleeve by low-pressure water spray and cooling; tempering the roll sleeve after quenching the roll sleeve; turning and grinding the roll sleeve, so that the technological requirement of processing drawing is met; turning and grinding the outer circle of the mother mill roll, so that the outer circle of the mother mill roll has the size matched with that of the inner circle of the roll sleeve in a thermal mode; heating the roll sleeve, preserving the heat, taking out the roll sleeve, matching and compounding the roll sleeve with the mother mill roll to form an integrated mill roll; tempering the integrated mill roll and eliminating the internal stress; turning and grinding the integrated mill roll, so that the technological requirement of processing drawing is met; and packaging and putting the products into a storage after the products are detected to be qualified. By the processing technology, the waste mill roll can be used reasonably and repeatedly, the service life of the hot-rolled aluminum plate mill roll can be prolonged, and the production cost of enterprises can be reduced.

Description

technical field [0001] The invention relates to the processing of a roll insert, in particular to a processing technology for recycling hot-rolled aluminum plate rolls. Background technique: [0002] Aluminum products have fully covered all areas of social life. In the production process of aluminum products, the crucial process is the hot-rolled aluminum plate. The quality of hot-rolled aluminum sheet is directly related to the quality of the final product in the aluminum product industry, and the key point is the problem of hot-rolled rolls. [0003] For a long time, due to the material loss of hot-rolled aluminum rolls and other reasons, various aluminum product companies have been troubled, so a large number of imported hot-rolled aluminum rolls have been used to meet production needs, which has brought about high investment, high cost, and low efficiency. Enterprises have a large number of rolls of various specifications that can no longer be used and are included in ...

[0003]For a long time, due to the material loss of hot-rolled aluminum rolls and other reasons, various aluminum product companies have been troubled, so a large number of imported hot-rolled aluminum rolls are used to meet production needs, bringing What is more serious is the phenomenon of high investment, high cost, and low benefit. All aluminum product enterprises have a large number of rolls of various specifications that can no longer be used and are included in the scope of scrapping, which seriously restricts the healthy development of aluminum product enterprises.
