Single pitch, uniform thickness spiral blades
Production Process: Proprietary special process cold pressing forming; bands below 80mm width feature continuous uniform helical blades made by continuous rolling; bands with large width, large outer diameter and small inner diameter, and large thickness have continuous uniform helical blades made by welding segmented uniform helical blades.
Product Advantages: Cold-pressed forming without affecting the physical properties of the spiral blade material; effectively guarantees the inner and outer diameters, pitch, and the perpendicular angle of the helical surface elements to the central axis; continuous, uniform thickness spiral blades with a width of 80mm or less are rolled continuously, with a smooth surface and no welds; large width, large outer diameter with small inner diameter, large thickness, and large pitch spiral blades are welded firmly with smaller welds, offering a smooth spiral curve and perfect spiral angle.
Common Materials: Carbon Steel, Manganese Steel, Stainless Steel, Wear-Resistant Steel, etc.
Product Specifications: Customized according to customer's requirements, continuous rolling of continuous equal-thickness spiral blades with a width below 80mm, large-width continuous equal-thickness spiral blades with a diameter of 1500mm and a thickness of 40mm.
Product Application: Suitable for various industries including mining, chemical, agriculture, environmental protection, and construction pile foundation projects.
Processing Range:
Hole diameter greater than 20mm, edge width less than 150mm, thickness 3-40mm.
