Abstract
An antioxidative paint for refractory steel is prepared from precipitated barium carbonate and silica as primary raw materials, as well as boric acid as flux and water glass as medium, and features that it can become a continuous enamelled layer under the action of high temp. Said enamelled layer features good spreading nature, not being stripped easily, not gasifying, no generation of enamel drops, and excellent antioxidative performance.
Description
What the present invention relates to is box hat outside surface antioxidizing paint, can be coated on the high temperature steel surface of life-time service temperature below 1300 ℃.Be specially adapted to the high temperature steel outside surface of smelting magnesium.
At present, the high temperature steel reduction that smelting magnesium uses jar does not apply antioxidizing paint, following jar of outside surface oxidation peeling of working temperature about 1200 ℃ and air atmosphere, attenuate tank wall thickness.Need because of producing, jar inside need keep certain vacuum tightness, and under atmospheric effect, the reduction jar behind the attenuate can be out of shape and scrap.Can prevent a reduction jar oxidation peeling after applying antioxidizing paint, prolong the work-ing life of reduction jar.
Second phase nineteen ninety-five " non-ferrous metal " magazine (smelting part) has been delivered one piece " high-quality spray material of fire-resistant oxidation resistant-nickel chromium triangle aluminium composite powder ".This technology is a kind of cladding type composite metal powder, with plasma spraying or oxyacetylene torch spraying.Can direct anti-982 ℃ high temperature.Its cost height, constructing operation and facility complexity, and also use temperature is on the low side.
" refractory materials " third phase in 1991 has been delivered the article of a piece " development and use of aluminium carbon refractory product antioxidizing paint ".This technology is used frit and rare earth oxide and some additives, is mainly used in the anti-oxidation of ceramic product surface, and nonmetallic surface.
The objective of the invention is to make a kind of with low cost, batching is simple, and the use temperature height can form the high temperature steel antioxidizing paint of continuous glaze layer in working temperature.
Main points of the present invention are: based on precipitated barium carbonate, silica, water glass is vehicle, adds a small amount of fusing assistant boric acid and makes coating.With 100 parts of (weight) precipitated barium carbonates, after 30-60 part (weight) ground silica and the mixing of 0.5-10 part boric acid are ground altogether, add water glass, make coating.Can adopt spraying, dipping or manual brushing, about coat-thickness 1.5mm, can use after the seasoning.
This coating is at room temperature to 800 ℃ formation duricrust, and 1000 ℃ begin glazings, and still intact up to 1300 ℃ of glaze layers, spreadability is good, does not vaporize, and does not produce glaze and drips, and good with high temperature steel surface affinity, anti-oxidation performance is good.
Embodiment:
100 parts of (weight) precipitated barium carbonates
50 parts of (weight) ground silicas
90 parts of (weight) water glass
3 parts of (weight) boric acid
To make coating after the above mixing of materials, adopt spraying, dipping or manual brushing on the high temperature steel surface, use can heat up after the seasoning.
In electric furnace, half brushes this coating with the common die steel, heat treated under air atmosphere.After 1000 ℃ of insulations thermal treatment in 3 hours, be cooled to room temperature, peel remaining coating off, be coated with the thick 5.9mm of part steel disc that is brushed with coating, the thick 6mm of former steel disc, the thick 4.6mm of part steel disc of coating.
Claims (2)
1. oxidation-proof paint for high-temp heat-resistant steel, it consists of: 100 parts of (weight) precipitated barium carbonates, 30-60 part (weight) ground silica, 50-100 part (weight) water glass, 0.5-10 part (weight) boric acid mixed preparing forms.
2. antioxidizing paint according to claim 1 is characterized in that: can use constructional methods such as spraying, dipping, brushing, be coated in the high temperature steel surface of 1300 ℃ of maximum operation (service) temperatures.
