Cemented Carbide Roll (11)

Cemented carbide roller rings (also known as tungsten carbide roll rings), superior performance, quality and stability, high precision machining, good wear resistance and high impact resistance. The cemented carbide roller is a roll made ​​of tungsten carbide and cobalt material by powder metallurgy method. Cemented carbide roller integral and modular two kinds. It was in 1909, after the advent of powder metallurgy technology, with the development of the metal processing industry was born. Since 1918, Germany launched a cemented carbide drawing dies, inspired national cemented carbide, have appeared in a variety of uses roll.

However, the cemented carbide roller a large number of applications in 1960. Morgan (Morgen) first high-speed twist-free wire rod mill was born in 1964, was the finishing speed of the wire increased 4 times. Since finishing mill work in the high-speed, high stress, poor wear resistance of cast iron roll, tool steel roller, rolling groove short life, roll repair handling very frequent, affecting the performance of the mill, were not suited to finishing production requirements, it is to be substituted by composition cemented carbide roller. The world has more than two hundred sets of Morgan mill, the consumption of hundreds of tons of cemented carbide roller.
