The Tungsten Carbide Rings is a kind of tool material which consists of tungsten carbide and cobalt with high hardness and wear resistance.This kind of rings are used as work rings in stands of pre-finishing rolling mills, stands of finishing rolling mills and stands of reducing sizing mills.
Seven kinds of high-chromium steel (DS-A∼DS-G) having M 7 C 3 carbides, and four kinds of high-speed steel (HS-A∼HS-D) having MC+M 6 C carbides were used as roll materials. All rolls were 76 mm in diameter. Chemical compositions, carbide area and mean carbide spacing of each material are listed in Table 1; the mean carbide spacing is one factor that determines the carbide morphology.
