Tungsten carbide ring is a kind of tool material which consists of tungsten carbide and cobalt with high hardness and wear resistance.
Detail
Acicular bainite ductile iron roll adding nickel, manganese, chromium, molybdenum and other alloying elements, it is a needle-like organization(martensite and bainite) matrix, higher than the pearlite ductile iron roll strength, toughness and more well, wear Sui has improved markedly.
Alloy ductile iron roll is characterized by the ball-shaped graphite in the matrix, through adjusting the compositions of Ni, Cr, Mo adopting different heat treatment technology, pearlitic ductile iron and acicular constitution and different performance of anti-heat impact and resistance to wear.
We manufacture and supply a wide range of international quality work rolls. These work rolls are manufactured with high-quality alloyed steels.
The whole process form melting, casting, forging, heat treatment to final machining and packing is under control of quality system.
According to different requirements the carbide contents of the adamite rolls varies. When wear resistance is required, the content of the carbide must be higher; but when the strength is the main factor, it is necessary to select the lower content of the carbide. The heat treatment is normalized and tempered.
High speed steel rolls, produced by horizontal centrifugal casting process, are all compound rolls with high speed steel as the work layer and nodular iron as the core.
The high-Cr cast iron rolls are made by centrifugal casting process, the work layer contains 12-22% Chromium.
Indefinite chill cast iron is a material between chill cast iron and grey cast iron. The work layer of this material consists of flake graphites, while the depth below barrel surface increases, the amount of graphites will increase too, but the hardness will decrease.
