Abstract
A kind of preparation method of the zinc ingot metal ingot mold coating of zinc hydrometallurgy, agstone and calcined kaolin are uniformly mixed, and coating A powder is made, boric acid is dissolved in hot water, and coating A powder is then added and stirs evenly, obtains coating；Then use spray gun that coating even application in die surface, is formed coating.Since boric acid, agstone and calcined kaolin are chemically reacted at high temperature, the complex compound being made of calcium oxide, diboron trioxide, silica, alundum (Al2O3) is produced, high temperature resistant, strong adhesive force form effective coating.The present invention is the characteristics of being vulnerable to the etch of high temperature zinc liquid according to the cast iron casting mould of ingot casting; select suitable coating; in a certain temperature conditions; coating is applied in mold; it is allowed to generate uniform coating; so that zinc ingot metal and mold is generated isolation in ingot casting, protects mold not make etch, keep zinc ingot metal smooth bright and clean.
Description
Technical field
The present invention relates to a kind of zinc ingot metal ingot mold coatings, and in particular to a kind of zinc ingot metal ingot mold coating of zinc hydrometallurgy
Preparation method.
Background technology
In nonferrous smelting Zinc Hydrometallurgy Process, it is last procedure that zinc casting ingot, which is precipitated,.Iron used in casting zinc ingot metal
Mold, through a long time use, its inner wall can be kept uneven by the etch of high temperature zinc liquid, and can condense a thick layer of fouling,
Cause institute's output zinc ingot metal appearance pole out-of-flatness, that the handwriting is blurred is unclear for trade mark, and large area occurs and give a protective coating to metal objects and blackspot, seriously affects
The presentation quality of zinc ingot metal.In the past mold was handled there are two types of mode.First, using methyl-silicone oil etc. as coating material, but have very much
Disadvantage, such as not easy to operate, easy to fall off, uneven etc.；Second is that cleaning cleaning, manual cleaning are polished with angle grinder, labor intensity
Greatly, dust is big, seriously polluted, and clears up unclean, it is possible to damage mold；Chemical cleaning, mold will be dismantled, labor intensity
Greatly, it can not be continuing with and the mold of etch is after cleaning.
Invention content
It is an object of the invention to overcome the shortcomings of in existing method, propose that a kind of zinc ingot metal ingot mold of zinc hydrometallurgy applies
The preparation method of layer so that generate a coating between mold and zinc ingot metal, on the one hand mold is made to be protected, not by high temperature zinc
Liquid etch not will produce and give a protective coating to metal objects and blackspot, the presentation quality of zinc ingot metal is made to obtain on the other hand but also the good zinc ingot metal any surface finish of casting
Improve to very big.
To achieve the above object, the present invention adopts the following technical scheme that：
A kind of preparation method of the zinc ingot metal ingot mold coating of zinc hydrometallurgy mixes agstone and calcined kaolin equal
It is even, coating A powder is made, boric acid is dissolved in hot water, coating A powder is then added and stirs evenly, obtains coating；Then using spray
Coating even application in die surface, is formed coating by rifle.
The present invention, which further improves, to be, the mass ratio of agstone and calcined kaolin is (0.95~1.05):1；
The present invention, which further improves, to be, the temperature of hot water is 60~80 DEG C.
The present invention, which further improves, to be, the quality of boric acid is the 24% of the gross mass of boric acid and coating A powder, coating A
The quality of powder is the 76% of the gross mass of boric acid and coating A powder.
The present invention, which further improves, to be, the mass ratio of the gross mass and hot water of boric acid and coating A powder is 3:5.
The present invention, which further improves, to be, every kilogram of coating can spray 7~8 square metres of die surface.
Compared with prior art, the device have the advantages that：Since boric acid, agstone and calcined kaolin are in height
It is chemically reacted under temperature, produces the complication being made of calcium oxide, diboron trioxide, silica, alundum (Al2O3)
Object is closed, high temperature resistant, strong adhesive force form effective coating.The present invention is to be vulnerable to high temperature zinc according to the cast iron casting mould of ingot casting
The characteristics of etch of liquid, selects suitable coating, in a certain temperature conditions, coating is applied in mold, is allowed to generate equal
Even coating makes zinc ingot metal and mold generate isolation in ingot casting, protects mold not make etch, keep zinc ingot metal smooth bright and clean.In spraying,
Mold need not be removed from system, direct spraying keeps operation simpler, avoid in disassembly process the damage of mold and
Damage.
Specific implementation mode
The present invention will be described in detail below.
The preparation method of the present invention is as follows：
1) agstone and calcined kaolin are uniformly mixed, coating A powder is made, wherein agstone and calcining kaolinite
The mass ratio of soil is (0.95~1.05):1；
2) boric acid is dissolved in 60~80 DEG C of hot water, coating A powder is then added and stirred evenly, obtain coating；Wherein,
The quality of boric acid is the 24% of the gross mass of boric acid and coating A powder, and the quality of coating A powder is the gross mass of boric acid and coating A powder
76%, the mass ratio of the gross mass and water of boric acid and coating A powder is 3:5.
Then with spray gun by obtained coating even application in die surface, form coating.
The ingot quality that every kilogram of coating is sprayable 50 times is that 25 kilograms of zinc ingot metal ingot mold surface (is equivalent to 7~8
Square metre).
Since boric acid and agstone and calcined kaolin are chemically reacted at high temperature in the present invention, produce by
The complex compound of calcium oxide, diboron trioxide, silica, alundum (Al2O3) composition, high temperature resistant, strong adhesive force are formed
Effective coating.The use of the mold coating effectively eliminate zinc ingot metal surface give a protective coating to metal objects and blackspot, significantly improve outside zinc ingot metal
Appearance quality, and mold is made to be protected, it is not easy, by zinc liquid etch, to extend the service life of mold.The coating formula is used
Easily operated in production, labor intensity is small.After the coating, zinc ingot metal surfacing is bright and clean.It is detected through analysis, coating is answered
With not to any adverse effect of zinc ingot metal quality generation.
By GB/T12689-2010<Zinc and kirsite chemical analysis method>12nd part, inductively coupled plasma transmitting
Spectroscopic methodology analyses and compares to the zinc ingot metal before and after using coating, and result is as follows：
Before use：Lead：0.0028 cadmium：0.0008 iron：0.0008 bronze medal：0.0004 tin：0.0002 aluminium:0.0002；
After use：Lead：0.0028 cadmium：0.0009 iron：0.0008 bronze medal：0.0003 tin：0.0001 aluminium:0.0003.
After the coating of the zinc ingot metal spraying present invention, any surface finish, before the coating, surface color is dim.
