Roller coater liquid throwing prevention device for improving hot galvanizing passivation quality and liquid throwing prevention method

Abstract

The invention discloses a roller coater passivation roller coating device suitable for a continuous hot galvanizing high-speed unit, relates to the technical field of roller coater liquid throwing prevention devices for improving the passivation quality of continuous hot galvanizing, and in particular to a roller coater liquid throwing prevention device for improving the hot galvanizing passivation quality and a liquid throwing prevention method. Liquid throwing prevention device bodies are symmetrically arranged on a rack on the two sides of a coating roller of a roller coater, the liquid throwing prevention device bodies comprise slag scraping and grinding plates, flushing mechanisms, liquid blocking brushes and flow guide protective covers, and the problems that when an existing rollercoater is used, passivation liquid is prone to being thrown out, the passivation liquid is caused to flow to the edge part of strip steel or splash to the middle of the strip steel, a large amount ofpassivation liquid splashes to pollute the surrounding operation environment, even the passivation liquid is thrown out into eyes of an observer, and eye injuries are caused are solved. The working efficiency is improved, guarantee is provided for smooth production of a production line, and the safety risk of field operators caused by liquid throwing is reduced.

Description

technical field [0001] The invention is suitable for the passivation roller coating device of the roller coater of the continuous hot-dip galvanizing high-speed unit, relates to the technical field of the anti-swing liquid device of the continuous hot-dip galvanizing passivation quality improvement roller coater, and is specifically a kind of hot-dip galvanizing passivation quality improvement The anti-spin liquid device and the anti-spin liquid method of the roll coater. Background technique [0002] For the horizontal roller coater, as long as the roller coater is used to apply the passivation solution to the products produced during the production process, the type of passivation solution and the coating method of the passivation solution directly affect the roller coater. Liquid rejection is easy to occur on the high-speed production line, causing the passivation solution to adhere to the steel strip between the racks of the roller coater and the steering roller under th...

Problems solved by technology

[0006] The object of the present invention is to: when the above-mentioned existing roller coater is in use, it is easy to throw out the passivation solution, causing the passivation solution to flow to the edge of the strip or splash in the middle of the strip, and a large amount of passivation solution Splashing will pollute the surrounding working environment, and even cause the passivation liquid to be thrown into the observer's glasses, causing eye damage. The invention provides a roll coater anti-throwing liquid device for hot-dip galvanizing to improve passivation quality and anti-spin liquid method
