Abstract
The invention discloses a water gap lining layer material for continuous casting. The material is prepared from the following components in percent by weight: 20-60 percent of corundum, 0-30 percent of electrofusion zirconium mullite, 0-40 percent of fused silica, 3-40 percent of ceramic hollow sphere, 1-10 percent of light burning alumina, 2-6 percent of sintering assistant, 2-6 percent of phosphate bonding agent and 4-8 percent of solid phenolic resin bonding agent. A water gap for continuous casting produced by adopting the material is suitable for cold casting, and a lining basically has no nodule blocking phenomenon; the lining has high strength and does not have phenomena of chambering and abnormal erosion; a water gap has long service life; and the continuous casting production efficiency is improved.
Description
Technical field:
The present invention relates to a kind of inorganic non-metallic refractory materials, particularly relate to submerged nozzle, the long nozzle that in continuous casting steel machine is produced, uses, the air retaining wall material that descends continuous casting mouths such as the mouth of a river, filling pipe end.
Background technology:
On continuous casting process; in order to protect cast to prevent secondary oxidation of steel; the main both at home and abroad at present carbon containing mouth of a river of using mostly is aluminium carbonaceous, aluminium carbon zirconium mass and the magnesia submerged nozzle of aluminium carbon, long nozzle and other open type mouths of a river, and its wedding agent mainly is a resol carbon coupling system.The known fact is that in the cast steel process, this carbon containing refractory can produce decarburization, and causes mouth of a river inwall settling (Al
2O
3Nanocluster) gather and stop up the mouth of a river, especially submerged nozzle, tundish upper nozzle dross, stop up the most serious.
For addressing the above problem, need the air retaining wall material of above-mentioned continuous casting mouth be made improvements, following several technical scheme is arranged at present:
1, adopt magnesium-aluminium spinel (60-90wt%) to make the carbon less and silicon less liner, but still the graphite of introducing 3-6% is to improve processability, at casting oxygen composition during than higher steel grade, because the reaction of the graphite in oxygen and the inner lining material, inner lining material can cause short texture and not anti-erosion and washing away, and work-ing life is short
2, liner is made up of zircon, silicon nitride and aluminum oxide, by obtaining ZrO behind the high temperature sintering
2Particle is distributed in the Sialon matrix and anti-deposition, but its anti-erosion, anti-molten steel scouring ability are relatively poor.
3, liner adopts aluminium zirconium-magnesium A Long based material, has introduced the newer senior refractory raw material of magnesium A Long especially, be that low temperature intensity is not high to the problem of the use maximum of silicon nitride, Sialon or A Long material, and work atmosphere requires harsh.
4, form loose no carbon-coating at mouth of a river inwall, dip-coating does not have carbon pastes so that this no carbon-coating of closeization then, and the major defect of this scheme is that this no carbon-coating is more loose, and anti-molten steel scouring time ratio is shorter, and dipping process is had strict demand.
Summary of the invention:
The purpose of this invention is to provide a kind of have well prevent to stop up, scour resistance is strong, the air retaining wall material of the continuous casting mouth of long service life.For achieving the above object, the technology used in the present invention solution is: a kind of water gap lining layer material for continuous casting, it is characterized in that each weight percentages of components is: corundum 20-60%, fused zirconia-mullite 0-30%, fused quartz 0-40%, ceramic hollow ball 3-40%, calcined alumina 1-10%, sintering aid 2-6%, phosphate binders 2-6% and heat-reactive phenolic resin wedding agent 4-8%.
The present invention further technical characterictic is:
Wherein said corundum is provided by in white fused alumina, plate diamond spar, the brown corundum one or more.
Described ceramic hollow ball is aluminum oxide, zirconium white matter or fly ash float.
Described sintering aid is provided by in potassium felspar sand, norbide, boric acid, clay, the low temperature glass frit one or more.
Described phosphate binders is provided by in phosphoric acid, aluminum phosphate, aluminium dihydrogen phosphate, the primary magnesium phosphate one or more.。
The invention has the beneficial effects as follows:
Owing to introduce phosphate binders in the air retaining wall material of the present invention, further reduce and bring the resol consumption of carbon residue, thereby effectively reduce the carbon content of air retaining wall, anti-erosion and scour resistance significantly improve; Introduce ceramic hollow ball in the air retaining wall material of the present invention, improved the thermal shock performance of material, be suitable for cold opening and water, liner does not have the dross latch up phenomenon substantially, lining strength height, no reaming, unusual corrosion phenomenon, mouth of a river long service life has improved continuous casting production efficiency.
Embodiment:
The invention will be further described below in conjunction with the production process of continuous casting mouth:
Embodiment 1)
As shown in table 1: with 20 parts of corundum; 30 parts of fused zirconia-mullites; 40 parts of ceramic hollow balls; 1 part of calcined alumina; 2 component sintering additives; use high speed granulator all to mix; add 2 parts of phosphate binders and the granulation of 5 parts of heat-reactive phenolic resin wedding agents mixing high speeds; then through drying bed or the rotary drying kiln drying of flowing; when treating that material is chilled to normal temperature; adorn mould; use the cold isostatic press moulding; earlier air retaining wall is adopted the premolding of 30-80Mpa pressure; the good interior hole body of premolding is after simple finishing; the dress mould; add the body material of continuous casting mouth and the material of other particular requirements (as the slag line material) then, under 100-160Mpa pressure, wait the static pressure composite molding again.Next, according to different continuous casting mouth products, to moulded products adopt that the different process route carries out drying respectively, burns till, machining, glazing, installation iron cover and insulation fibre, carry out quality inspection again, packing can be made the continuous casting mouth that adopts inner lining material of the present invention.In addition, because the present invention is incorporated into ceramic hollow ball in the inner lining material, air retaining wall of the present invention is control thickness accurately, reduces even avoids road amount of machining afterwards.Wherein said corundum is provided by in white fused alumina, plate diamond spar, the brown corundum one or more.Described ceramic hollow ball is aluminum oxide, zirconium white matter or fly ash float.Described sintering aid is provided by in potassium felspar sand, norbide, boric acid, clay, the low temperature glass frit one or more.Described phosphate binders is provided by in phosphoric acid, aluminum phosphate, aluminium dihydrogen phosphate, the primary magnesium phosphate one or more.。
