Electromagnetic Rubber and Plastic Calendaring Heating Mirror Roller

Material selection of high-quality carbon steel, stainless steel or alloy steel. After heat treatment tempering, multiple stress relief, quenching. The wall thickness of the inner hole is uniform after processing, and the surface hardness after quenching is HRC50-58.
Internal structure: two or three layers, spiral or Z-shaped runner, with heating or cooling function. Inner sleeve and roller body interference red fitting. Water in and out on both sides or water in and out on the same side.
The introduction of leading grinding and polishing facilities, the selection of high-quality 3M abrasive, precision grinding, finish Ra0.01um(i.e. 14 level).
Surface treatment: hard chrome plating, ceramic spraying, polishing, grinding and other processing.
Mirror processing can be carried out on the surface of various materials, from flatness, balance, non-roundness, coaxial degree, etc., to ensure the accuracy of the roller. Temperature difference ≤±1ºC, thermal deformation ≤0.01mm, flatness & runout & coaxiality ≤0.001mm.
Mirror roller is widely used in plastic sheet film, decorative materials, clothing fabrics, leather, paper, metal, film, nonwoven materials and other materials surface calendering, high precision coating.
Type: alloy steel mirror roller; Super mirror roller; Plain mirror roll
With the wide application of heating roller in various industries, electromagnetic heating roller is replacing heat conduction oil heating roller, so far electromagnetic heating roller is successfully used in laser anti-counterfeiting printing, die stamping, automotive laminated glass composite, composite film production, medical tape, pharmaceutical packaging, non-woven fabric production, aluminum-plastic panel agglutination, synthetic fiber, rubber and plastic calendaring and other industries.
1. Energy saving - 60% energy saving comparing with the heat conduction oil roller or steam roller;
2.High precision temperature control, temperature precision reaches ±0.5ºC;
3.Faster heating up- takes only 25 min from room temperature to 200 ºC;
4.High working temperature, roller surface temperature can reach above 400 ºC for operation , satisfies the requirement of high temperature production;
5. Environmental protection - all electric control, no oil pollution, clean production environment.

1)Printing and dyeing industry: calendering of pure cotton, polyester cotton, silk fabrics, chemical fiber, hemp, woolen fabrics and their blends.
2)Leather industry: calendering of artificial leather, etc.
3)Plastic industry: PVC, ABA, PP, PT, PC and other plastics.
4)Paper industry: surface calendering of various papers.
5)Metallurgical industry: rolling processing of various non-ferrous metals.
 Processing technology
1) Component welding:
Assemble the inner plate, shaft head, bushing, plugging plate, inner tube, etc. The inner tube is within 50g of static balance, the inner tube is drawn in the direction of rotation, and the flat steel flow channel is welded.

Component welding:
Assemble the inner plate, shaft head, bushing, plugging plate, inner tube, etc. The inner tube is within 50g of static balance, the inner tube is drawn in the direction of rotation, and the flat steel flow channel is welded.

Equipped with vehicles, installed and welded:
Equipped with the inner tube of the car, the size and the interference of the outer tube are 0.4mm, the angle of the welding seam of the two plates is 15X30 degrees, the inner tube is polished, the slag is cleaned, and the size of the inner tube is matched with the inner diameter of the outer tube. After shrinking, the whole assembly welding.

3) Annealing, rough turning, quenching:
Annealing heat treatment, process quenching and tempering, multiple stress relief, rough turning margin, static balance, greater than 50g, need to calculate the amount of deviation, borrow the car on the lathe.
Quenching: The surface hardness requires HRC58°-60°, and the roller surface has no cracks.

4)Fine turning and rough grinding

5)Dynamic balance, electroplating, and fine grinding

6)frosted, finely polished mirror surface

Advantage:
1)Material:We adop

t 45# seamless steel pipe, alloy steel, precision forgings or rolled round 45# steel pipe
a. Mirror rollers are generally made of 45# steel, alloy steel seamless tubes, precision forgings and other materials, and the surface finish of the roller can reach Ra0.01 (level 14);
b. The roller blank is made of professional imported alloy steel, and different flow channel structure forms are designed according to different material characteristics;
c. Mirror processing can be performed on the surface of various materials to ensure that the straightness, balance, non-roundness and coaxiality of the roller surface meet the requirements;

2)Sand blasting process: It can improve the fatigue resistance of the workpiece, increase the adhesion between it and the coating, extend the durability of the coating film, and also help the leveling and decoration of the coating, and remove impurities, variegation and oxide layer on the surface At the same time, the surface of the medium is roughened, the residual stress on the substrate surface and the effect of increasing the hardness of the substrate surface. The etching process is a chemical surface treatment method, which sometimes will affect the appearance of the finished product.
3)Quality:Usually chromium is critical for mirror roll products. Our surface requirements for mirror roller is usually determined by the thickness and hardness of the chromium layer.While these are determined by many years of experience in the surface processing of rollers. It is difficult for general customers to make a profit in this regard. According to the analysis, if the quality of the surface chromium layer is not hard enough, its surface will have a substantial impact on the production of sheet products such as PC, PP, PMMA, PET, etc., and this is an important factor that causes the durability of the roller.
