摘要:
A cooling roll (5) for producing magnet materials, comprising a roll base material (51) and a surface layer (52) covering the outer periphery of the material, wherein the roll base material (51) is preferably formed of a metal material of a high heat conductivity, and the surface layer (52) is formed of a material lower in heat conductivity than the roll base material (51) and preferably formed of ceramics. The surface layer (52) satisfies the relation, 1.01
摘要(中):
一种用于制造磁体材料的冷却辊(5),包括辊基材(51)和覆盖材料外周的表面层(52),其中辊基材(51)优选地由金属材料 导热率高,表面层52的导热性低于辊基材(51),优选由陶瓷形成。 表面层(52)满足1.01≤Tmax/Tmin≤3的关系,其中Tmax是表面层(52)的最大厚度,Tmin是最小厚度。 辊基材(51)的周面(511)的表面粗糙度Ra为0.03〜8μm。
