Description
Technical Field
The utility model mainly relates to the technical field of hard alloy production equipment, especially, relate to a deformed steel carbide roll.
Background
The steel hard alloy is a composite material reinforced by using steel as a binder and doping 30-50% of hard carbide, so that the steel hard alloy is named as a carbide reinforced steel-based composite material, and rollers processed by using the steel hard alloy are collectively called as steel hard alloy rollers. It was developed with the help of cemented carbide. It combines the high strength, high hardness and high wear resistance of hard compound and ceramic material and the strength, plasticity and toughness of steel, and is in the position between common hard alloy and high speed steel.
After a common hard alloy roller is used for a period of time, an inner hole is easy to wear and lose efficacy, the stability of the dimensional precision of the special-shaped steel wire is directly influenced, the roller needs to be stopped for maintenance or replacement, and the production efficiency is severely limited. However, the whole roller is made of hard steel alloy material, the equipment cost is high,
therefore, the invention needs to invent a deformed steel hard alloy roller, which not only can reduce the abrasion of the inner hole of the roller, but also can be suitable for production and save the cost.
