Problems solved by technology
[0002] At present, most components of the zinc pot equipment currently used in cold rolling mills are immersed in zinc liquid and are corroded by high-temperature zinc liquid for a long time, especially the rotating sinking roll and stabilizing roll, which are eroded and worn by zinc liquid and need to be replaced frequently (The replacement cycle is 15 days to 20 days), which not only greatly affects the productivity, but also is detrimental to the quality of the coating product

The invention discloses a novel pot-roller-free galvanizing device, and relates to the technical field of hot galvanizing devices. The device comprises a lower cavity, turning rollers and stabilizingrollers are arranged in the lower cavity, the stabilizing rollers are arranged above the turning rollers, an upper cavity is arranged above the lower cavity, a zinc pot is arranged on the lower portion in the upper cavity, and zinc liquid is arranged in the zinc pot. A ceramic channel is connected to the lower portion of the zinc pot and connected with the lower cavity, an induction coil surroundsthe ceramic channel and is connected with an alternating current motor, air knives are arranged on the upper portion in the upper cavity, and the alternating current enables the induction coil to form an alternating current magnetic field. An eddy current opposite to the current in the induction coil is formed on the surface of the zinc liquid by the alternating current magnetic field, and the electromagnetic force formed by the alternating current magnetic field of the alternating current and the eddy current generated in the zinc liquid and the static pressure of the zinc liquid can be balanced by adjusting the alternating current so as to control the liquid level.
Description
technical field [0001] The invention relates to the technical field of hot-dip galvanizing devices, in particular to a novel galvanizing device without pot rolls. Background technique [0002] At present, most components of the zinc pot equipment currently used in cold rolling mills are immersed in zinc liquid and are corroded by high-temperature zinc liquid for a long time, especially the rotating sinking roll and stabilizing roll, which are eroded and worn by zinc liquid and need to be replaced frequently (The replacement cycle is 15 days to 20 days), which not only greatly affects the productivity, but also is detrimental to the quality of the coating product. Contents of the invention [0003] In order to overcome the above-mentioned defects of the prior art, the present invention provides a novel galvanizing device without a pot roller. eddy current, when the electromagnetic force formed by the alternating magnetic field and the eddy current generated in the molten z...
