A liquid level cleaning device applied to the nose of a hot-dip galvanizing furnace

Abstract

The invention discloses a furnace nose inner liquid level cleaning device applied to hot galvanizing. The furnace nose inner liquid level cleaning device comprises a first liquid level, a second liquid level and a third liquid level, the first liquid level is a liquid level at the intersection position of a furnace nose and outer zinc liquid, the second liquid level is a trough plate liquid levelin the furnace nose, and the third liquid level is a liquid level between a trough plate and a furnace nose shell. The trough plate is located in the furnace nose and located between strip steel and the furnace nose shell. The first liquid level is higher than the second liquid level, and the second liquid lever is higher than the third liquid level. Through the furnace nose inner liquid level cleaning device applied to hot galvanizing, the technical effects that gathering of harmful impurities such as zinc dust and slag in the furnace nose is reduced, the harmful impurities can be dischargedout of a system in time, the dynamic stability and cleanness of the zinc liquid in the furnace nose are maintained, and the surface quality of the strip steel is improved are achieved.

Description

technical field [0001] The invention relates to the field of hot-dip galvanizing technology for cold-rolled sheets, in particular to a liquid level cleaning device applied to the nose of a hot-dip galvanizing furnace. Background technique [0002] In the galvanized sheet production line, high-quality products require a good surface quality, especially the surface quality after galvanizing requires smoothness and no defects. [0003] However, in the process of realizing the technical solution of the invention in the embodiment of the present application, the inventor of the present application found that the above-mentioned prior art has at least the following technical problems: [0004] In actual production, due to the complex working environment inside the furnace nose, some zinc slag or zinc ash often accumulates in the furnace nose. Because it is very close to the strip steel, it will inevitably affect the quality of the galvanized surface. Zinc slag or zinc ash defects...
