Custom size 140X90X15mm PR2~PR8 Cemented Carbide Roller for Welded Steel Fabric Reinforcement

Detailed Description:

Carbide rolls are one of the main consumable parts of hot rolling mills, cold rolling mills, steel pipe rolling mills and high-speed wire rod rolling mills, with huge consumption. Continuously adopting new technologies to improve the quality and precision of rolled products and reduce production costs is the development direction of today's rolling technology. At the same time, it also puts forward higher requirements for the wear resistance, strength, toughness and oxidation resistance of the rolls.

In order to adapt to this requirement, hot rolling roll materials have been continuously improved and developed, from the early ordinary chilled cast iron, infinite chilled alloy cast iron, high chromium cast iron, high chromium cast steel: to the current widespread use abroad of high-speed steel and cemented carbide. The improvement and development of roll materials are closely linked to their preparation methods. The development of roll materials from single materials to composite materials has promoted the development of roll preparation methods, and greatly improved the performance-price ratio of roll materials and the service life of rolls. Among them, the preparation methods of roll materials are also constantly improving, from ordinary Casting developed to centrifugal casting and then to squeeze casting: from powder metallurgy to hot isostatic pressing and combustion synthesis.
