Zinc pot roller ceramic wall sleeve structure and zinc pot roller assembly

Abstract

The invention discloses a zinc pot roller ceramic wall sleeve structure which is used for being connected with the two ends of a zinc pot roller in the axial direction, and the zinc pot roller ceramic wall sleeve structure comprises a roller arm, a ceramic wall sleeve, a ceramic wall sleeve body and a ceramic wall sleeve body, and the connecting position of the roller arm and the zinc pot roller is provided with a groove; the bracket is arranged in the groove, and a lining groove is formed in the bracket; the ceramic lining is arranged in the lining groove, and the inner surface of the ceramic lining is in contact with the shaft sleeve of the zinc pot roller. Correspondingly, the invention further discloses a zinc pot roller assembly which comprises the zinc pot roller ceramic wall sleeve structure and the zinc pot roller.

Description

technical field [0001] The invention relates to the field of cold-rolled hot-dip galvanizing, in particular to a zinc pot roll wall sleeve structure and a zinc pot roll assembly. Background technique [0002] Cold-rolled hot-dip galvanized zinc pot roll is the key process equipment of hot-dip galvanizing unit, and the stability of its operation directly affects the quality of the product. Since the zinc pot rolls work for a long time in the zinc liquid at 450°C, the zinc liquid at high temperature will cause certain corrosion to the rolls and the roll arms and arm sleeves on both sides, or the surface of the zinc slag will stick to the surface, resulting in abnormal operation of the rolls. Cause groove marks, scratches or other product quality defects on the surface of the steel plate. Therefore, it is usually necessary to replace the zinc pot roll and the arm sleeves on both sides after about 2 weeks of production, so as to ensure the stable operation of the roll and the q...

Problems solved by technology

[0008] The above three existing technologies all disclose a ceramic bearing structure, although it can prolong the service life of the arm sleeve, but the cost of spare parts of this structure is relatively high; and the sealed structure makes the disassembly and assembly of the ceramic bearing more complicated and easy to cause damage; Its cylindrical structure is directly installed on the roller arm. It is very inconvenient to disassemble the roller arm to remove the roller and arm sleeve every time the zinc pot roller is unloaded and dezincified.

[0009] It can be seen that although the traditional metal arm sleeve structure can be used in production, it has a relatively short service life. After two weeks of use, the metal sleeve is prone to abnormal wear, which will affect the stability of the operation and cause the product to be damaged. quality defects

In the prior art, the cylindrical structure of the ceramic bearing pad is adopted, although the service life can be prolonged, but the use cost is relatively high, and the disassembly and assembly process of the ceramic bearing pad is relatively complicated, which may easily cause damage to the ceramic bushing.

[0010] Based on this, in order to solve the problem of the short service life of the metal arm sleeve of the original zinc pot roll in the zinc liquid for a long time, and aiming at the defects of the existing traditional metal arm sleeve of the zinc pot roll, the present invention expects to obtain a ceramic wall sleeve structure of the zinc pot roll , which has good wear resistance and is not easy to stick to zinc. Compared with the traditional ceramic bearing shell cylindrical structure, it has the characteristics of low cost and convenient disassembly and maintenance.
