Furnace nose for hot-dip galvanizing with detachable slag discharge pipe and method of use thereof

Abstract

The invention relates to the field of hot-dip galvanizing alloy technology and the equipment used therefor, in particular to a furnace nose for hot-dip galvanizing with a detachable slag discharge pipe and its use method. A furnace nose with a detachable slag discharge pipe for hot-dip galvanizing, comprising a furnace nose body (1), characterized in that it also includes a partition (21), a bottom plate (22), a slag discharge pipe (3), zinc Liquid suction pump (4), support (5) and liquid zinc discharge pipe (6), the lower half of the inner cavity of the furnace nose body (1) is provided with a partition (21), and the support (5) is detachable It is fixed on the bottom of the outer wall of the furnace nose body (1). A method for using a furnace nose with a detachable slag discharge pipe for hot-dip galvanizing, which is characterized in that: it is implemented in sequence as follows: A. When the furnace nose is in operation, insert the lower part of the furnace nose body (1) into the zinc pot ( 7) Under the zinc liquid surface; B. When the furnace nose moves laterally, release the detachable fixation respectively. The invention has good slag discharge effect, high galvanizing quality, convenient disassembly and assembly, and strong adaptability.

Description

technical field [0001] The invention relates to the field of hot-dip galvanizing alloy technology and the equipment used therefor, in particular to a furnace nose for hot-dip galvanizing with a detachable slag discharge pipe and its use method. Background technique [0002] Steel is currently the most widely used metal in the world, but steel materials are easily corroded under the combined action of air and water. In order to reduce the corrosion of steel materials, the more common method is to coat the steel surface with protective Since zinc has good corrosion resistance in the atmosphere and is a relatively cheap metal, the cost of using zinc as a protective layer is low, so hot-dip galvanizing has become the most widely used method of metal rust prevention. [0003] The production of modern galvanized sheets generally has to go through stamping process, which puts forward high requirements on the ductility of strip steel. Therefore, the strip steel of continuous hot-dip...

AI Technical Summary

Problems solved by technology

At present, with the development of industry, the surface quality requirements of galvanized sheets are increasing day by day. For example, the galvanized sheets used for the outer panels of automobiles require that the defects cannot be distinguished by the naked eye. Therefore, zinc gray marks, zinc slag marks and the resulting indentations Defects such as scratches and scratches will seriously affect the surface quality of the strip, which is not suitable for the needs of modern industry

[0004] In order to effectively discharge the zinc ash and zinc slag in the furnace nose, there are currently various furnace noses with slag discharge structures. On the bottom plate, the furnace nose with such a structure is suitable for the zinc pot that can be moved horizontally, but for the zinc pot that needs to be moved horizontally, the lateral movement of the zinc pot will be blocked by the slag discharge pipe, so the furnace nose must be disassembled before the zinc pot is moved horizontally , It takes 8 to 12 hours to disassemble and assemble the furnace nose once, which makes the zinc pot stop production for a long time, consumes a lot of man-hours and greatly reduces production efficiency
