It is divided into upper and lower sizing rollers. This rubber roller is composed of a thick-walled cast iron pipe, a bulky head, and a combination of drying and installation of the shaft head. The roller surface is covered with rubber, and the shaft end is equipped with a bearing seat, a bearing cap, and a bearing.

Precautions

1：The sizing roller will produce an aging layer due to long-term use, the hardness will increase or the surface will have slight cracks. Once this happens, it is best to remove the sizing roller from the machine for re-grinding and grind off the rubber surface. . 5mm-1. 0mm. And then use it again.

2：When the operating pressure of the sizing roller is greater than or equal to 80KN/M or the operating speed is greater than or equal to 600M/MIN. Then the roller core of the sizing roller should be equipped with a water cooling system. For this reason, when the sizing roller and another sizing roller with a surface temperature of ≥95°C are mutually released and used, the cooling system measures mentioned above need to be taken. The amount of water used for water cooling must be sufficient, and the temperature difference between inlet and outlet water should be ≤5°C.
