Description
Technical field
The invention belongs to Casting High Speed Steel fields, and in particular to a kind of self-control cast steel roll mould wash and preparation method thereof.
Background technique
Cast steel roll is mainly that H profile steel pony roughing mill, large and medium-sized Bar Wire Product shaping roll are used, and casting process is generally
Coating need to be carried out on moulding mould inner wall using coating to completely cut off wall of die cavity and steel contacts, practical moulding produced
Alcohol-base foundry coating is generally used in journey, there is a situation where that poor by molten steel impact, adhesive property is bad in use process causes
Related casting crack shim situation occurs.
Summary of the invention
Goal of the invention: in view of the above-mentioned deficiencies in the prior art, it is an object of the present invention to provide a kind of self-control cast steel roll moulding
Coating and preparation method thereof.
Technical solution: in order to achieve the above object of the invention, the present invention is specifically achieved like this: a kind of self-control cast steel rolls
Roller mould wash, the component including following parts by weight: 65 ~ 80 parts of zirconium English powder, 15 ~ 25 parts of industrial alcohol, 2 ~ 5 parts of rosin, paste
2 ~ 5 parts and 5 ~ 12 parts of bentonite of essence.
Wherein, the purity of the industrial alcohol is 99%.
The method of preparation self-control cast steel roll mould wash, comprising the following steps:
1) preparation of solvent: rosin is crushed, and is added in industrial alcohol solution, after rosin dissolution, bentonite is added and stirs
30 ~ 40min, rear sealing solution tank storage；
2) zirconium English powder is poured into paint can, configured rosin alcoholic solution is added, stir 25 ~ 30min, make zirconium English powder in outstanding
Floating uniform state；
3) coating sprays: after waiting roller molds to go out drying chamber, removing roller surface and floats sand and flue dust, be down to≤50 DEG C to sand mold temperature
After coat, to roller surface carry out two secondary coatings, 2.0 ~ 2.4kg/cm of coating first layer density3, coating second layer density 1.6
~2.0 kg/cm3, paint thickness control is in 2 ~ 5mm, and each coating should apply uniformly without accumulation and part holiday phenomenon, and coating is complete
After assembled.
Wherein, using being detected respectively with densimeter to two sides coating in the step (3), reaching requirement can make
With.
Wherein, carry out lighting coating after first coating brush is complete in the step (3), after be cooled to 50 DEG C hereinafter, then
Surface floating dust is removed, then brushes the second coating and lights, is cleared up and is assembled after cooling.
The utility model has the advantages that the present invention compared with traditional technology, has the advantage that
(1) present invention is alcohol-base foundry coating, it is at low cost, prepare it is easy, using quick, environmental pollution is smaller, without unfavorable strong
Health influences；
(2) coating provided by the invention can with meet washing away and corroding for molten steel long period, avoid molding sand and steel contacts
Scab and crackle are formed, surface of cast steel roll quality is promoted；
(3) present invention is using the method to two secondary coating of roller surface, and burns after primary coating to coating, makes coating
First time high temperature bond is carried out with roll sand mold, achievees the purpose that coating in conjunction with mould surface densification, when secondary coating is reduced
Coating density can be the close of the compacted zone that secondary coating and primary coating form new compacted zone after ignition, and newly formed
Degree is slightly below the conjugation that the first coating Yu roll sand mold has been effectively ensured in first layer.
