◆The materials are selected from high-quality 45# seamless steel pipes, alloy seamless steel pipes, etc., after heat treatment and tempering, the inner wall of the pipe is finished with uniform wall thickness, and the inner wall of the pipe is heated with an interference red sleeve, welding, stress relief, finishing, quenching, and after quenching. The surface hardness reaches HRC50~58. The roller body can be installed with inner bile duct sleeve and multi-head spiral flow channel structure or two-layer, three-layer sleeve and Z-shaped flow channel structure according to customer requirements, while ensuring that the balance meets the user's requirements, one in and one out or in and out on the same side water.
◆ The roller surface is mirror-finished to ensure that the straightness, out-of-roundness and coaxiality of the roller surface are less than or equal to 0.005mm.
◆ Imported original abrasive belt and polishing equipment produced by American 3M company, roughness Ra0.01 (finish grade 14), which is currently the highest-grade mirror roller processing equipment in China.
◆ Cooling temperature difference ≤±1℃, deformation ≤0.01mm. The surface is plated with hard chrome, the hardness is HRC65. After polishing, there is no vibration pattern, streak, napping pattern.
● Widely used in sheet (board) material machines, coating machines, laminating machines, printing machines, leather machines, plastic packaging machinery and leather, artificial leather, paper, film, aluminum foil, glass, cloth, decorative materials, non-ferrous metals, PVC , ABS, PP, PE, PT, PC and other plastics and clothing surface cooling.
