Description

Mechanical electromagnetic type zinc slag fixed-point driving device for hot galvanizing and application method thereof
Technical Field
The invention relates to the field of hot dip plating processes using molten coating materials without affecting the shape, in particular to a mechanical electromagnetic zinc dross fixed-point driving device for hot dip galvanizing and a use method thereof.
Background
Steel is one of the most widely used metals in the world at present, but steel materials are easily corroded in air, water or soil. The method of coating the protective layer on the surface of the steel is a commonly used method for preventing corrosion of steel materials, and hot galvanizing is currently the most widely used method for preventing rust of steel.
In order to improve the ductility of a galvanized steel sheet, annealing is required before strip steel enters a zinc pot for hot galvanizing, the strip steel directly goes deep into the zinc pot from an annealing furnace through a furnace nose and turns upwards through a sink roll, the zinc pot is pulled out through two stabilizing rolls, a pair of symmetrical air knives are arranged above the zinc pot, compressed air is blown to the strip steel by the air knives to scrape off redundant zinc liquid, the required thickness of a galvanized layer is obtained, and the strip steel continues to move upwards after passing through the air knives and then enters a rear procedure through cooling to complete the galvanization process.
The temperature of the zinc pot is up to 450 ℃, and the main component in the zinc liquid is zinc, and trace elements such as aluminum, silicon, magnesium, iron and the like are also included. Because of the continuous production of the strip steel, iron can be continuously brought into a zinc pot, the solubility of the zinc liquid to the iron is certain, and the iron in the zinc liquid can react with zinc and aluminum to generate zinc slag beyond the solubility. In a zinc pot with the aluminum content of more than 0.13%, zinc slag has a specific gravity smaller than that of zinc liquid, can float to the surface of the zinc liquid, and the zinc slag floating on the surface must be fished out at regular time, otherwise, can adhere to the surface of strip steel to form zinc slag marks.
The strip steel is positioned between the two air knives at the position of the zinc outlet pot, and zinc slag on two sides of the strip steel can be blown away from the strip steel for a certain distance (about 200 mm-300 mm) under the action of compressed air flow sprayed by the air knives. At present, a manual slag stirring mode is commonly adopted for hot galvanizing, an operator uses a tool with a spoon or a scraping plate, which is 4-5 m long, to penetrate into the middle of a zinc pot to stir the zinc slag floating above the zinc liquid to two sides of the zinc pot, and then dials to the rear of a nose of the zinc pot to drag out the zinc slag. In the process of slag stirring, because some zinc slag can float on the strip steel to affect the quality of the strip steel, a roll of transition roll (usually a color-pattern substrate, a packaging material and the like with low requirements on surface quality) is required to be arranged when slag is pulled manually, so that when high-grade hot-dip galvanized sheets such as automobiles and household appliance sheets are produced, a roll of transition roll is required to be inserted when 3-4 rolls are produced, and the production efficiency is seriously affected. In addition, the manual slag pulling is high in risk, high in labor intensity and low in production efficiency in a high-temperature zinc pot environment.
