Irreplaceable Mother Roll

Irreplaceable Mother Roll

Editor’s Note The roll is known as the mother of rolled materials, and every piece of rolled material is rolled by a roll. Therefore, the quality of the roll is directly related to the surface quality of the rolled material, which restricts the operating rate of the rolling mill and the output of the rolling mill. In order to demonstrate the new technologies, New products will further improve the level of rolling production. Sinosteel Metallurgical News – China Iron and Steel News Network will open a new column “Rolling New Technology Tour” written by the expert group of Chaoyang Lianqiang Roll Co., Ltd. for readers.
The irreplaceable mother roll of rolling material The roll is a tool for plastically deforming (rolling material) metals, and is an important consumable part that determines the efficiency of the rolling mill and the quality of the rolling material. The types of silver rolling can be divided into cast rolls and forged rolls according to the forming method; according to the process method, they can be divided into integral rolls, metallurgical composite rolls and combined spokes. Integral car silver is divided into two types: integral casting and integral forging rolls.
Metallurgical composite casting mainly includes semi-flush composite casting, overflow (full flush method) composite casting, and centrifugal composite casting. In addition, there are continuous flow casting, spray deposition, hot isostatic pressing, and electroslag welding. Composite rolling silver types manufactured by special composite methods. Combined rolls are mainly nested combined rolls. According to the manufacturing materials, the rolls are mainly divided into three categories: cast steel series rolls, cast iron series rolls and casting series rolls. Among them, cast iron-based materials with a carbon content of less than 2.2% are called cast steel series; cast iron-based materials with a carbon content greater than 2.2% are called cast iron-based materials; forged iron-based materials are called forged series,In order to adjust and optimize the urban layout and spatial structure, expand the environmental capacity and ecological space, and promote industrial upgrading and transfer, the original Tangshan Lianqiang Roll Co., Ltd. invested RMB 630 million to establish Chaoyang Lianqiang To Think Co., Ltd. in Liucheng Economic Development Zone, Chaoyang City, Liaoning Province. The company aims to improve the level of equipment through strategic transfer, and establish a new type of rolling plate manufacturing enterprise with high output, high efficiency and high dedication.
