HBW05 is a new type of material specially developed by our company for KOCKS rolling mill bar production line. The hardness of the roll surface is HSD84-89, the uniformity of the roll surface hardness: ≤3HSD, the hardness drop/mm: ≤2HSD. The hardness difference of 3 roller rings of the same hole type is less than or equal to 3HSD. Single grinding amount (reduction): ≤1 mm. The material has high wear resistance and impact toughness under thermal load, so the product has high wear resistance and impact toughness, no ring burst phenomenon, and low processing difficulty. Its steel passing capacity can reach 60-80% of the cemented carbide roller ring, the price is less than 50% of the alloy roller ring, and the frequency of slot changing can reach 2 shifts.

LMM tries its utmost to meet the demand of customers. Our professional R&D department and production line will provide the direct and effective quality and service for you.

Before determining the grade of cemented carbide for every stand, we shall have a thorough understand about theirproperties so as to make the correct choice (Please refer to the Product manual).

The cemented carbide composite roll is mainly used on the finishing mill for bar, deformed steel bar and common wire. In this way, we can greatly reduce the frequency of changing groove and roll, thus to reduce the labor intensity and improve the work efficiency. The surface quality and yield shall be improved to a maximrurn degree, which leads to a rernarkable ecornmoic benlefit.

During the use of Cementer carbide roll , under good cooling conditions, a thin and dense oxide film is formed on the surface of the roll body. This uniform, thin and dense oxide film can exist for a long time without falling off, so that the wear resistance of the Cementer carbide roll is significantly improved.
