Problems solved by technology

However, in the whole production process, the zinc ash and zinc slag in the zinc pot not only seriously affects the quality of the galvanizing layer, but also causes the coating to be rough and produces zinc nodules.
Moreover, the cost of hot-dip galvanizing is greatly increased

Embodiment Construction

[0008] As shown in the accompanying drawing: a method for reducing zinc ash and zinc slag in the zinc pot 1. Add alumina-containing ceramic beads 3 with a diameter of ∮7-15mm on the surface of zinc 2 in zinc pot 1, and spread them densely and evenly on the surface of zinc 2, about three to four layers of alumina-containing ceramic beads 3, The thickness is about 20-45mm. Thereby, the formation of zinc ash and zinc slag in the prevention and control of the zinc pot is achieved.

Abstract

The invention provides a method for reducing zinc ash and zinc residues in a zinc pot. Alumina ceramic beads with the diameters phi of 7-15mm are added to the surface of zinc in the zinc pot, and are densely and uniformly tiled on the zinc surface in a three-layer or four-layer manner, and the thickness is about 20-45mm. The method has the following advantages: the heat loss can be reduced and the oxidation can be prevented because the alumina contained ceramic beads have the characteristics of anti-oxidation function, small heat conductivity, high melting point, small specific gravity, and no reaction with molten zinc. Alumina has an iron removal function, so the formation of iron impurities of the zinc pot is reduced. The beads which are balls can be pushed away by workpieces, and do not adhere to the workpieces. The method well controls the generation of the zinc ash and the zinc residues in the zinc pot.

Description

(1) Technical field [0001] The invention relates to a method for reducing zinc dust and zinc slag. The invention relates in particular to a method for reducing zinc ash and zinc slag in a zinc pot. (2) Background technology [0002] Hot-dip galvanizing, also known as hot-dip galvanizing, is a method in which steel components are immersed in molten zinc to obtain a metal coating. In recent years, with the rapid development of high-voltage power transmission, transportation, and communication, the requirements for the protection of steel parts are getting higher and higher, and the demand for hot-dip galvanizing is also increasing. However, in the whole production process, the zinc ash and zinc slag in the zinc pot not only seriously affects the quality of the galvanizing layer, but also causes the coating to be rough and produces zinc nodules. Moreover, the cost of hot-dip galvanizing is greatly increased. Usually, 40-80kg of zinc is consumed per 1 ton of workpiece to be p...
