The high-temperature coating material has the mass percent that quartz sand is 15 to 30 percent, soluble glass is 20 to 40 percent, water is 40 to 50 percent, and thickening agent is 1 to 5 percent. The granularity of the grain size of the quartz sand ranges from 1 to 200 micrometres, and the thickening agent is water-soluble celluloses. The high-temperature coating material has the advantages that the material is used for the surface coating protection when in hot working of the steel billet or the steel workpiece, and the allowable heat resistant temperature reaches 1300 DEG C; the raw material source is wide, the cost is low, the preparation technology is simple, the operability is strong, and the material can be coated on the surface of the steel workpiece directly and evenly through coating by a brush directly or soaking, etc.; and the applicability is wide.
Description
Technical field
The present invention relates to the coated material that metal heat treatmet technology is used, oxide coating material when particularly preventing steel billet or steel workpiece hot rolling.
Background technology
Oxidation can take place in steel billet or steel workpiece when high-temperature heat treatment, can influence the quality of steel part and mechanical property etc.Material corrosion that oxidation causes and top layer decarburization not only make the tissue damaged of material, and have increased the treatment process of scale removal and Decarburized layer, have greatly influenced the economic benefit that ferrous materials is produced, thereby have been paid close attention to by people always.Adopting the inorganic high-temp oxidation resistant coating is to reduce metallic high temperature oxidation loss efficient ways.So-called inorganic high-temp oxidation resistant coating promptly can prevent the workpiece oxidation with workpiece and air insulated in heat treatment of workpieces.Because it is different that the different and concrete protection of the metallic matrix of required protection requires, correspondingly need to adopt the coating of different performance.
From the forties in last century, people have just carried out research and have obtained many achievements high-temperature oxidation resistant coating.Along with the continuous development of heat-stable material, the optimization of formulation for coating material and coating preparation technology's improvement, the paint coatings performance improves and improves, and uses more extensively, and coating variety is more and more.But present antioxidizing paint both domestic and external is owing to complex process, and the cost height is unfavorable for scale operation and extensively popularization.Domestic steel alloy and the special steel problem of oxidation in course of hot rolling is very outstanding, has had a strong impact on quality, effect and the competitive power of steel rolling product.It is simple relatively to study a kind of preparation, and starting material are extensive, and cheap high-temperature oxidation resistant coating has very realistic meanings.
Summary of the invention
The object of the present invention is to provide a kind of high-effect high-temperature oxidation resistant, cheap, preparation is simple, coated material easy to use;
These coated material starting material are extensive, and the preparation method is simple, and is easy to use, and anti-oxidation/decarburization effect is good, and suitability is wide, and heat resisting temperature reaches 1300 ℃.
Technical scheme of the present invention is:
The high temperature-resistant coating material that hot continuous rolling steel billet of the present invention or iron and steel workpiece are used is made up of quartz sand, water glass, water and thickening material, and its composition quality per-cent is:

The coated material of table 1 embodiment 1 is formed
| Quartz sand | Water glass | Water | Binding agent |
| 15 | 30 | 40 | 1 |
Ingredient requirement:
1 micron～200 microns of quartz sands
The preparation method is:
Heat water to 50 ℃～80 ℃ earlier, put into water glass, stir, keep fluid temperature between 50 ℃～80 ℃, add quartz sand while stirring, add thickening material, to be mixed evenly after, stop to stir and heating, promptly get product.
Experimental result:
Behind the coated inoxidzable coating of steel part, after 1200 ℃ of 2 heat was pricked, about air cooling to 680 ℃, coating and metal were peeled off naturally.
In different hot-rolled temperature scaling loss amounts, the results are shown in Table 2.
Table 2 embodiment 1 usefulness Φ 25mm steel grade: Gr15 is in different hot-rolled temperature scaling loss amounts
| Hot-rolled temperature | 1000℃ | 1200℃ |
| The scaling loss amount that the coating steel part is arranged | 1％ | 1.2％ |
| The scaling loss amount of no coating steel part | 2.1％ | 3.5％ |
