AI Technical Summary
During the zinc pot insulation process, the zinc liquid needs to be kept in a molten state and continuously heated, resulting in high energy consumption. At the same time, the surface of the zinc liquid is oxidized to produce ZnO impurities, which increases costs.
A zinc pot insulation device is used, including a combination structure of steel support, steel wire mesh and refractory asbestos, which covers the surface of the zinc pot to reduce the heat dissipation rate and prevent oxidation.
The temperature and heat dissipation rate of the zinc liquid are reduced, the oxidation of zinc is reduced, and the energy and auxiliary material costs are saved.

Abstract
Description
Technical Field
[0001] The utility model relates to a zinc pot insulation device, belonging to the technical field of energy and environmental protection of hot-dip galvanizing equipment in the metallurgical industry. Background Art
[0002] After a continuous hot-dip galvanizing line finishes production, the zinc slag on the surface of the zinc bath is cleaned to prepare for the next production run. During this period, the zinc bath needs to be kept molten and continuously heated. This process also oxidizes the surface of the zinc bath, generating ZnO impurities that are detrimental to the next production run and increase costs.
[0003] To reduce the cost of zinc liquid consumption during the waiting period, two main approaches are taken. First, lower the holding temperature. The temperature provided by the induction heater only needs to keep the zinc liquid in a molten state, and then the temperature is raised to the production temperature during production. Second, reduce the consumption of zinc liquid temperature. If the rate of zinc liquid temperature loss during the waiting period can be reduced, the starting frequency of the inductor can be extended, reducing energy consumption.
[0004] Based on the above two points of analysis, a zinc pot insulation device was invented. Covering the zinc pot during production not only reduces energy consumption, but also reduces the oxidation rate and proportion of zinc, reducing the cost of auxiliary materials. Utility Model Content
[0005] The purpose of the utility model is to provide a zinc pot insulation device, which can reduce the heat dissipation speed of zinc liquid, prevent zinc from being oxidized by oxygen, save energy, and solve the problems existing in the background technology.
[0006] The technical solution of the utility model is:
[0007] A zinc pot insulation device comprises a zinc pot rim, refractory asbestos, a steel bracket, a clip and a steel mesh. There are multiple steel brackets, both ends of each steel bracket are respectively clipped on the zinc pot rim, and two adjacent steel brackets are connected by clips. Each steel bracket is provided with a steel mesh, and each steel mesh is provided with refractory asbestos.
[0008] The steel wire mesh is laid flat and fixed on a steel support.
[0009] Refractory asbestos is fixed on the upper and lower surfaces of the steel wire mesh.
[0010] The steel bracket is a rectangular structure formed by welding multiple steel pipes. The length of the steel bracket matches the length of the zinc pot, and the number of steel brackets is determined according to the width of the zinc pot.
[0011] The buckle is a U-shaped structure formed by bending a stainless steel wire.

[0018] The present invention will be further described below with reference to the accompanying drawings and examples.
[0019] Refer to the attached Figure 1-4 A zinc pot insulation device comprises a zinc pot edge 1, refractory asbestos 3, a steel bracket 4, a buckle 5 and a steel wire mesh 6. There are multiple steel brackets 4, and the two ends of each steel bracket 4 are respectively clamped on the zinc pot edge 1. The adjacent two steel brackets 4 are connected by the buckle 5. Each steel bracket 4 is provided with a steel wire mesh 6, and each steel wire mesh 6 is provided with refractory asbestos 3.
[0020] In this embodiment, refer to the attached Figure 1-4 The zinc pot insulation device comprises a zinc pot edge 1, zinc liquid 2, refractory asbestos 3, a steel bracket 4, a buckle 5 and a steel wire mesh 6, wherein:
[0021] The steel bracket 4 is welded from a stainless steel tube with an outer diameter of ф=40mm and an inner diameter of ф=30mm. The length of the steel bracket 4 is 4600mm, excluding the 30mm at both ends extending under the pot edge. The width of the steel bracket 4 is 800mm; the steel wire mesh 6 is welded from stainless steel wire with a diameter of ф=1mm, and the steel wire mesh 6 is welded to the steel bracket 4; the refractory asbestos 3 is a polycrystalline mullite fiber blanket with a width of 810mm, which is laid on the upper and lower surfaces of the steel wire mesh 6, and the refractory asbestos 3 and the steel bracket 4 are fixed by stainless steel wire; the buckle 5 is a U-shaped structure formed by bending a stainless steel wire with a diameter of 6mm; the two ends of the steel bracket 4 are clamped at the two ends of the zinc pot edge 1, and the two adjacent steel brackets 4 are connected to each other by the buckle 5.
[0022] First, make a single steel bracket 4, and determine the number of steel brackets 4 according to the size of the zinc pot. Due to the complex environment surrounding the zinc pot, the steel bracket 4 is too wide to be disassembled and taken out, and the size of the steel bracket 4 is adjusted according to the actual situation.
