Embodiment Construction

[0011] Such as figure 1 , figure 2 As shown, the present invention includes: induction coil 1 , ceramic tube 2 , heat insulation sleeve 3 and refractory shell 4 . The ceramic tube 2 is placed inside the induction coil 1 , the heat insulation sleeve 3 is arranged between the induction coil 1 and the ceramic tube 2 , and the induction coil 1 , the ceramic tube 2 and the heat insulation sleeve 3 are all placed in the refractory shell 4 .

[0012] The ceramic tube 2 is a honeycomb-shaped ceramic tube with square holes, which is formed by extruding ceramic slurry and then sintering.

[0013] The induction coil 1 is wound by a copper tube, and circulating water flows through the inside of the copper tube.

[0014] The heat insulating sleeve 3 is formed by pressing calcium-silicon plate material with excellent heat insulating performance.

[0015] The present invention can be placed individually or in multiples in the hot-dip galvanizing pot, especially in the position where ther...

Abstract

Disclosed is an electromagnetic cleaning means for hot galvanizing liquid which comprises an induction coil, a honeycomb shaped square ceramic tube, a heat insulation sleeve and a housing of refractory material, wherein the ceramic tube is arranged inside the induction coil, the heat insulation sleeve is arranged between the induction coil and the ceramic tube. The device is placed in the zinc coating liquid located inner the belt steel for cleaning treatment.

Description

technical field [0001] The invention relates to a purification device in the technical field of metal smelting, in particular to a hot-dip galvanizing liquid electromagnetic purification device for removing zinc slag in the hot-dip galvanizing liquid. Background technique [0002] Hot-dip galvanizing is by far the most common and effective process measure used in steel corrosion protection methods. Hot-dip galvanized steel sheets produced by modern continuous hot-dip galvanizing processes are widely used in light industry, home appliances, construction and automobile industries. Especially in recent years, with the rapid development of the automobile industry, the demand for hot-dip galvanized steel sheets for automobiles continues to increase. In addition to the requirements for corrosion resistance, strength, and deep drawability of automotive sheets, high surface quality is also a basic condition that must be met. Zinc slag in hot-dip galvanizing bath is the most import...
