Abstract

The invention discloses an abrasion-resistant corrosion-resistant composite alloy roller barrel and a production process. The abrasion-resistant corrosion-resistant composite alloy roller barrel comprises a roller body which is a hollow cylinder. The roller body is composed of an alloy steel layer and an ordinary steel layer. The ordinary steel layer is integrally cast on the inner side of the alloy steel layer. The alloy steel layer comprises C, Si, Mn, P, S, Cr, Ni, Mo, V, Ti, Al, Cu, W, Re and the balance Fe and inevitable impurities. In general, the abrasion-resistant corrosion-resistant composite alloy roller barrel and the production process have the advantages that the production process of the roller body is innovated; steeling is replaced with casting, and the quenching step is omitted; the corrosion resistance, the abrasion resistance and the strength of the roller body are effectively improved; the production manufacturing precision of the finished roller body is improved; the service life of the roller body is prolonged; the quantity of raw materials used for production is decreased; the production cost is reduced; the abrasion-resistant corrosion-resistant composite alloy roller barrel and the production process are suitable for the beer industry, the food machinery industry, the paper making industry, the printing and dyeing industry, the chemical industry and other industries; and the practical value is very high.

Description

technical field

[0001] The invention belongs to the field of roll production, and relates to a roll cylinder and a production process, in particular to a wear-resistant and corrosion-resistant composite alloy roll cylinder and a production process. Background technique

[0002] At present, fertilizer production and manufacturing are developing rapidly. Granulation in the process of fertilizer production is a key step in fertilizer molding. The quality of fertilizer granulation rollers directly affects the final quality of fertilizer production.

[0003] The existing manufacturing process of fertilizer granulation rollers mainly uses steel columns for coring processing. After the processing is completed, quenching is carried out to improve the overall strength of the roller body. However, deformation often occurs during the quenching process and seriously affects the accuracy of the roller body. Quenching treatment will have higher hardness, but the roller body will be diffic...
