1. Company Introduction
Jiangsu Qizhan Intelligent Machinery Co., Ltd. is a manufacturer of pleating machine and mirror rooller. Our products are widely recognized and trusted by users and can meet continuously changing economic and social needs.
2. Product Introduction
Steel pipe and tube mill roll, an industrial machine.
The characteristics of steel tube mill rolls different from other types of mill rolls are:
(1) The surface defects and rough surfaces of the tube blank produced by the upper frame are difficult to eliminate on subsequent frames, which means that the steel tube rolls used for all frames should have good wear resistance.
(2) The surface and bottom of the steel tube roll hole should be uniform and wear-resistant, which is especially important for large-caliber pipes. Therefore, the hardness of the bottom of the hole should be used as an important indicator of the quality of the steel tube roll. The characteristics of steel tube mill rolls different from other types of mill rolls are:
1) The surface defects and rough surfaces of the tube blank produced by the upper frame are difficult to eliminate on subsequent frames, which means that the steel tube rolls used for all frames should have good wear resistance.
2) The roll hole surface and bottom should have uniform hardness and wear resistance, which is especially important for large-caliber pipes. Therefore, the hardness of the bottom of the hole should be used as an important indicator of the quality of the steel tube roll.
See the table for the classification and material selection of the steel tube rolls. Listed in the table are the general selection methods of steel pipe roll materials. In order to improve the abrasion resistance of rolled alloy steel pipe or large-diameter steel pipe rolls, for continuous tube mill rolls with roll necks, cast-iron cast iron series rolls can be selected; for roll ring type tension reducer rolls, etc. Then you can choose centrifugal cast iron series rolls. These processes improve the hardness of cast iron series rolls.
