Furnace nose with slag blowing and discharging structure for hot galvanizing belts and use method thereof

Abstract

The invention relates to the field of the hot-dip galvanizing alloy technology and adopted equipment, in particular to a furnace nose with a slag blowing and discharging structure for hot galvanizing belts and a use method thereof. The furnace nose with the slag blowing and discharging structure for the hot galvanizing belts comprises a zinc pot (1), an annealing furnace chute (2) and a furnace nose body (3) and is characterized by further comprising a molten zinc drawing pump base (41), a molten zinc drawing pump (42), a suction pipe (43), a discharging pipe (44), a molten zinc blowing pump base (51), a molten zinc blowing pump (52) and a blowing pipe (53), wherein the molten zinc drawing pump base (41) and the molten zinc blowing pump base (51) are fixed to the outer side surface of the bottom of the furnace nose body (3). The use method of the furnace nose with the slag blowing and discharging structure for the hot galvanizing belts is characterized by sequentially including the steps of arranging, liquid blowing and slag removing. The furnace nose and the use method thereof have the advantages that the slag removal effect is good, the galvanization quality is high, the operation is convenient, and the manpower and the labor hour are saved.

Description

technical field [0001] The invention relates to the field of hot-dip galvanized alloy technology and equipment used therefor, in particular to a furnace nose for hot-dip galvanized strip blowing and slag discharge structure and its application 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 ...

AI Technical Summary

Problems solved by technology

These furnace noses are equipped with one or two slag discharge pipes, which are welded to the bottom plate of the furnace nose slag discharge funnel. The furnace nose with this structure is suitable for lifting zinc pots, but it is not suitable for horizontally moving zinc pots. It is very difficult, because the slag discharge pipe blocks the movement of the zinc pot, the furnace nose must be disassembled first to move the zinc pot, and it takes 8 to 12 hours to disassemble the furnace nose, so the movement of the zinc pot must be stopped for a long time time, and additionally increased a large amount of manual workload, and there is also the problem that zinc ash and zinc slag are easy to gather on both sides of the short side of the furnace nose
