Tungsten carbide roll collar formula

Abstract

The invention discloses a tungsten carbide roll collar formula being capable of effectively solving the problems of low combination property and low rolling amount of the traditional tungsten carbide roll collar. The tungsten carbide roll collar formula comprises the following components in weight percentage: 93-98 percent of WC, 1.5-5 percent of Co, 0-4 percent of Ni, 0.2-0.3 percent of TiC, 0.2-0.3 percent of CrC, 0.05-0.3 percent of VC and 0.05-0.1 percent of Y. The invention has the advantages that the raw material composition and the component proportion of a tungsten carbide roll are improved so that the tungsten carbide roll has the internal condition formed by an internal organization structure meeting the service performance requirement, and moreover, the roll collar has small abrasion loss, smooth surface and long service period, cannot be broken and has low roll replacing frequency, and thus, the roll replacing work load is reduced, the cost is reduced, the operating rate of a rolling mill and the product quality are improved and the inherent quality and the surface quality of produced wire rod products are ensured.

Description

technical field [0001] The invention relates to a formula for a tungsten carbide roller ring. Background technique [0002] The roll ring is a key tool to make the rolled piece plastically deform and obtain the ideal design shape. The wear resistance of the roll ring directly affects the surface quality of the wire product and the production efficiency of the rolling mill. High-quality tungsten carbide roll rings were developed late in our country, and the surface quality and internal quality of the produced rolls are poor. The amount of rolling is small, and it is difficult to meet the requirements of high-speed wire rod and high-quality alloy steel rolling. In addition, the international advanced level of high-speed wire rod finishing rolling unit and reduction unit continuously introduced in China, the tungsten carbide roll ring of the finished product and the finished front frame rolling mill undertakes the dual functions of plastic deformation and product specification...
