Problems solved by technology

In the extrusion friction process, the material with relatively low strength is first consumed, so that the squeeze roller will not dry after a period of time.
Frequent replacement of the squeeze roller will be time-consuming and labor-intensive, which will affect the table and increase the cost of spare parts

Abstract

The invention discloses a surface fluid driving device. The device comprises a fan, a bracket and two pressure-equalizing chambers, wherein the bracket is connected with the fan; the two pressure-equalizing chambers are symmetrically arranged on the bracket up and down; rectangular narrow slots which correspond to each other in position are formed in the two pressure-equalizing chambers; and each pressure-equalizing chamber comprises an outer shell and an inner shell which is sleeved in the outer shell, wherein the outer shell is designed into a hollow pentagonal prism structure with two closed ends, the inner shell is designed into a hollow cylindrical structure with an opened end and a closed end, and a flow-equalizing wall is horizontally arranged between the outer shell and the inner shell and divides the space between the outer shell and the inner shell into two independent chambers. According to the surface fluid driving device, pressurized gas is sprayed from the slots of the outer shells of the pressure-equalizing chambers to form a gas cutter, and the gas cutter is used for scraping excessive liquid substances on the surface of a band steel, so that the quality and the yield of a product are increased substantially, and the device is also convenient to maintain.

Description

technical field [0001] The invention relates to the technical field of pickling processing of strip steel, in particular to a device for driving off surface liquid after pickling of strip steel. Background technique [0002] From the point of view of producing hot-dip galvanized steel sheets, the use of hot-rolled strip steel for direct hot-dip galvanizing is the same as the use of cold-rolled steel sheets. Before galvanizing, the strip steel should have a clean and active surface. In order to obtain such a surface, the hot-rolled strip needs to be treated to remove the surface oxide scale, and the usual practice is to carry out pickling treatment. The main components of iron oxide scale are three oxides of iron (FeO, Fe 3 o 4 , Fe 2 o 3 ), they are all amphoteric oxides that are insoluble in water, and can undergo metathesis reactions with strong bases and acids under appropriate conditions to form water-soluble salts. When they are immersed in the acid solution, these...
