4.Characteristics of the carbide mill rolls
High hardness and good wear resistance:hardness at room temperature can reach HRA78-89,good red hardness under high temperature,600°C over high-speed steel,1000°C over the room temperature of carbon steel.
High mechanical strength:The compressive strengthof up to 60000MN/m2,900°C,the bending strength can still above 1000MN/m2.
High modulus of elasticity:Good rigidity at room temperature ,no significant plastic deformation, Young’s modulus is 2-3 times that of steel.
Corrosion resistance and good oxidation resistance :acid,alkali,600-800°C without significant oxidation .
The linear expansion coefficient is small: in the range of 20 to 400°C
3. Packing method: First in foam , then in paper cartons and the last in wooden cases.
