Application: Caterpillar road pavers WKTL PC6, PC3, PC9, PC4
Relation between welding & heat treatment:
The carbide tip is firmly brazed to the steel body. When the extremely high temperature generated during the milling process acts on the part, the carbide and steel on the tip of the needle act. The road planing bit is affected by differential expansion. The self-developed brazing method determines the hardness of the picking head under the action of heat. This is a secret test through a lot of stress: even under the huge stress, there will be no breakage. The carbide tip is firmly bonded to the steel body.
High impact resistance:
The truncation must withstand large shear and impact stresses. At the same time, the cutting pick must be placed firmly and securely on the shank throughout its service life. HR cutting picks has a steel body that combines the two characteristics of wear resistance and breaking strength. Different grades of truncation and shaft hardness were produced during one test and test. Ed: When the tough boring shaft absorbs the forces generated in the area of the cutting pick, the hoe is additionally hardened, making the hoe extremely resistant to direct contact with the enamel.
In road milling technology, cutting picks play a decisive role and HR have been around for more than 10 years. During the milling process, they loosen the pavement and grind the pavement into small pieces of reusable material. Various working conditions and load conditions handled in the daily operation of the job site requirement.
