The classification of roller are there? Roller diameter: 25mm, 32mm, 38mm, 42mm, 50mm, 57mm, 60mm, 76mm, 80mm, 89mm. Roller material: galvanized steel, carbon steel, carbon steel, stainless steel, plastic bag, Aluminum Alloy and ABS. Roller type selection: no power roller, roller chain, double chain roller, "O" with a roller, roller, tapered roller groove. Fixed roller: spring-loaded, tooth shaft, flat tenon, through a pin hole type.
According to the process: stick, rolling pressure, roll casting singles;
According to the function of the use of points: heating roller, cooling roller, off the roller, roller, etc., according to the structure of seamless steel tube roller, forging and centrifugal casting roller, etc..
Roller production requirements
1 roller should have sufficient rigidity to ensure, under heavy load, the bending deformation does not exceed the allowable value.
2 roller surface should have sufficient hardness, generally reach HRC50 degrees, with strong corrosion resistance. The coating has anti stripping ability, ensure the working surface of the roller has good wear resistance and corrosion resistance.
3 roller working surface should be fine processing, to ensure the dimensional accuracy and surface roughness. Roughness should be more than Ra0.16, can not have pores or grooves. The working surface of the roller wall thickness should be uniform, otherwise it will make the roll surface temperature is not uniform, affect the quality of the products.
4 roller materials should have good thermal conductivity, usually using chilled cast iron, cast steel or special case with chromium molybdenum alloy steel, either heating or cooling, can achieve rapid and uniform.
Wenzhou Huada roller factory is a professional student roller manufacturers, has more than and 10 years of experience in production and processing operations, roller production by the new and old customers praise and favor. Hotline: 18958769825
