Since the introduction of the carbide drawing dies in Germany in 1918, it has stimulated the study of hard alloys in various countries. Rolls for various applications have also appeared one after another. However, a large number of applications of cemented carbide rolls are after 1960. In 1964, Morgen&#8217;s first high-speed twistless wire mill was launched, which increased the wire finishing speed by a factor of four. Because the finishing rolling mill is working under high speed and high stress, the wear resistance of the cast iron roll and the tool steel roll is poor, the life of the rolling groove is short, the loading and unloading of the roll is very frequent, and the efficiency of the rolling mill is affected, and the finishing rolling production is not suitable. The requirements were replaced by the combined cemented carbide roll. There are more than 200 sets of Morgan-type rolling mills in the world, which consume hundreds of tons of cemented carbide rolls.<\/div>\n<div>7. \u0623\u062f\u0627\u0621 \u0644\u0641\u0629

while the hardness and wear resistance is significantly higher than the common brand alloy, especially the wear resistance increased by 50% When used on the finished frame and finished product front frame, the roll life is 2 times that of the common brand of hard alloy; it can solve the problem of changing the roll together with the finished frame and the finished frame, which can significantly
