Core product: High performance wear-resistant spiral blades
The spiral blades of the paver produced by Datai Machinery are made of high wear-resistant alloy cast steel material, manufactured through optimized alloy ratios and advanced heat treatment processes. The blade working surface is designed with a reasonable wear-resistant structure, which can form a self-protection layer through material adhesion during use, effectively reducing the wear rate. Its main technical advantages include:
Balance between high hardness and high toughness: The surface hardness of the blade is precisely controlled, and it has good impact toughness, which can withstand the continuous impact and grinding of asphalt mixture and water stable materials during paving operations, avoiding collapse or fracture.
Accurate size and installation adaptation: The product is strictly designed according to mainstream paving machine models at home and abroad, such as BOMAG, Sany Heavy Industry, XCMG, Danapak, etc. The blade pitch, diameter, and installation hole position accuracy are high, ensuring perfect matching with the equipment and achieving “full burial” conveying of materials, effectively reducing segregation phenomena.
Optimized wear-resistant structure design: Drawing on advanced industry technology concepts, the blade working surface can be designed with a gradient type wear reduction structure. The groove layout that decreases from the blade edge to the center can store material particles, achieving the wear form of “material abrasive” and significantly improving the service life of the blade.
