Problems solved by technology

Due to the sealing effect inside the furnace nose, the exchangeability of the zinc liquid inside the furnace nose is poor, so impurities such as zinc ash and zinc dross often accumulate on the surface of the zinc liquid in the furnace nose. Defects of zinc slag and zinc ash, these defects seriously affect the surface quality of strip steel, and also threaten the normal production process of strip steel

Abstract

The invention relates to the field of pumping devices or systems, in particular to a zinc liquid pump for hot galvanizing. The zinc liquid pump for hot galvanizing comprises a driving motor (1) and a coupling (2), and is characterized by further comprising a bearing (3), a bearing base (4), a connecting rod (5), a pump shaft (6), a pump upper flange (7), a connecting bolt (8), a pump shell (9), an impeller (10) and a pump lower flange (11), wherein an output shaft of the coupling (2) is connected with the top end of the pump shaft (6); the impeller (10) is arranged in the pump shell (9); the bottom end of the pump shaft (6) penetrates into the pump shell (9) to be connected with the impeller (10); the top end of the pump shaft (6) coats the inner ring of the bearing (3); the bearing (3) is arranged in the bearing base (4); and the bearing base (4) and the pump upper flange (7) are fixedly connected by using the connecting rod (5). The zinc liquid pump for hot galvanizing is simple in structure, convenient to use and thorough in slag removal.

Description

technical field [0001] The invention relates to the field of pumping devices or systems, in particular to a liquid zinc pump for hot-dip galvanizing. Background technique [0002] Steel is the most widely used metal in the world. However, iron and steel materials are easily rusted due to corrosion in air, water or soil, forming loose and porous rust. The following is a simplified chemical reaction formula: 4Fe+2H2O+3O2=2(Fe2O3·H2O). Corrosion of steel causes huge losses, so a variety of anti-corrosion methods have been adopted one after another, among which the application of a protective layer on the surface of steel is the most common. Since zinc has good corrosion resistance in the atmosphere and is relatively cheap, the hot-dip galvanizing process is widely used. [0003] The zinc pot is the core equipment of the hot-dip galvanizing unit. During hot-dip galvanizing, the strip passes through the annealing furnace and then dips into the zinc liquid surface of the zinc po...
