Description
Technical field
The utility model relates to pot galvanize production technical field, particularly a kind of heat zinc coating plate surface zinc flower morphology control device.
Background technology
Heat zinc coating plate is widely used in production auto sheet, appliance plate and building panel.In order to improve erosion resistance and the japanning performance of heat zinc coating plate, especially in automobile exterior panel, the crystal habit (i.e. zinc flower) on common demands refinement heat zinc coating plate surface, to reach small zinc flower (between 400 microns to 1 millimeter, naked eyes can be differentiated reluctantly) even without the zinc flower size class of zinc flower (be less than 400 microns, naked eyes are invisible).
The control method of current heat zinc coating plate surface zinc flower pattern mainly contains following aspect:
(1) increase heat zinc coating plate surface crystallization quantity, the zinc flower quantity of unit surface is increased, thus reduces zinc flower size.Mainly comprise following several method: the surfaceness controlling zinc-plated raw material; Zinc powder or other finess is sprayed to galvanized sheet surface; Trace alloying element (as Ti) is added in zinc pot; Adopt the forming core core in electricimpulse effect increase zinc liquid.
(2) reduce the solidification temperature range of galvanized sheet surface zinc layers, shorten zinc layers setting time, make zinc flower have little time to grow up.Main method reduces some harmful element in zinc liquid as the content of Pb, Sb etc.
(3) cooling fast after plating: the method cools fast after heat zinc coating plate is gone out zinc pot, thus make zinc flower not have time enough to grow up, thus produce small zinc flower even without zinc flower prod.Mainly adopt the mode such as pressure-air cooling, water smoke cooling at present.Such as patent documentation: the small zinc flower production equipment (China Patent No. 201320169772.9) of surface of cold-rolled steel plate provides a kind of small zinc flower production equipment of surface of cold-rolled steel plate, the air spray box between air knife and cool wind box is utilized to spray air to galvanized sheet surface, reach the object accelerated zinc flower and solidify, thus small zinc flower size can be subtracted.
This production equipment has the following disadvantages: because the processing parameter such as thickness, thickness of coating, production rate, temperature of heat zinc coating plate is different, heat zinc coating plate is different by the setting rate of air knife rear surface zinc flower, this makes the position of solidifying of zinc flower not fix, the heat-eliminating medium of therefore jetting out from air spray box is difficult to accurately to aim at zinc and spends the position of solidifying, and cannot reach the object accelerated zinc flower and solidify.
Utility model content
The purpose of this utility model is to provide a kind of heat zinc coating plate surface zinc flower morphology control device, heat zinc coating plate for different thickness, different translational speed, different thickness of coating and differing temps is produced, accurately can aim at the position that zinc flower solidifies, to subtract small zinc flower size, improve the quality of products.
For solving the problems of the technologies described above, the utility model provides a kind of heat zinc coating plate surface zinc flower morphology control device, comprise cool wind box after the plating being positioned at the air knife that is arranged symmetrically in heat zinc coating plate both sides above hot-dip galvanized pan and being arranged symmetrically in heat zinc coating plate both sides, mobile air bellow is provided with between described air knife and the rear cool wind box of plating, described mobile air bellow is arranged symmetrically in heat zinc coating plate both sides and can moves up and down, moving up and down of described mobile air bellow is controlled by bellows mobile motor, and described bellows mobile motor is controlled by electric machine control system.
Further, the input parameter of described electric machine control system comprises galvanized sheet thickness, zinc plated plate plated layer thickness, galvanized sheet production rate and the temperature of galvanized sheet after air knife, and the output parameter of described electric machine control system comprises motor rotation direction and motor rotation speed.
A kind of heat zinc coating plate surface zinc flower morphology control device that the utility model provides, after air knife and plating between cool wind box, arrange in heat zinc coating plate zygomorphy and be provided with the mobile air bellow that can move up and down, the upper-lower position of mobile air bellow is accurately controlled by bellows mobile motor, make mobile air bellow can accurately aim at zinc flower solidify position, thus reach the object that quickening zinc flower solidifies and subtract small zinc flower size, make the distribution of the zinc on galvanized sheet surface flower more even, improve quality product, improve the qualification rate of product, save production cost.
