Abstract
A joint filler for converter is prepared from electrofused magnesite, magnesite-alumina spinel, silica powder, magnesite powder, graphite, additive and binder. Its advantages are high antioxidizing nature, high resistance to high-temp corrosion, high-temp scouring and thermal shock, low cost and not volatilizing easily.
Description
The invention belongs to the material field, particularly a kind of shaft and furnace bottom joint filler that is used for steel-making converter.
In metallurgical industry, rise bonding and filling effect with joint filler at the shaft of steel-making converter and the junction of furnace bottom.Usually adopt aluminium, magnesium, carbon be the joint filler of main raw material owing to contain a large amount of carbon, at high temperature become diffusing shape easily, its oxidation-resistance, high temperature resistant erosion and high temperature erosion are poor, make adhesiveproperties poor, and raw material is volatile exsiccation in the preservation process, and is perishable, influences construction quality.
The purpose of this invention is to provide a kind of joint filler for converter.It has oxidation-resistance, high temperature resistant erosion and high temperature resistant erosion good, good heat-shock resistance is at high temperature arranged, and cost is low, and not volatile exsiccation is easily preserved, and can improve the characteristics of execution conditions.
For reaching above-mentioned purpose, of the present inventionly it is characterized in that with electrosmelted magnesite clinker, magnesium-aluminium spinel, silica flour, graphite be major ingredient, add the additive that contains eutectic, add wedding agent again and form.
Consisting of of the material of major ingredient: (following each material is the weight meter)
Electrosmelted magnesite clinker: 20～80 parts; Magnesium-aluminium spinel: 5～30 parts; Silica flour and magnesium powder: 3～10 parts; Graphite: 10～15 parts;
The preferred oxalic acid of additive, Sodium Tetraborate, trimerization magnesium acid sodium, magnesite clinker and Sodium Silicofluoride.
Wedding agent adds solidifying agent by resin and machine oil and mixes.
The present invention is because employing electrosmelted magnesite clinker, magnesium-aluminium spinel, silica flour and magnesium powder, graphite are major ingredient, and close with main body furnace lining material material, plasticity-and cementability are convenient to furnace construction engineering well at normal temperatures.Oxalic acid, Sodium Tetraborate, trimerization magnesium acid sodium, magnesite clinker and the Sodium Silicofluoride of eutectic in additive, have been adopted, can impel the joint filler fusing point to reduce, make the at high temperature rapid sintering of joint filler reach certain intensity and become as a whole, therefore have good oxidation-resistance, high temperature resistant erosion and high temperature resistant erosion with the main body furnace lining material.Added wedding agent in the joint filler and added resin and machine oil, wherein resin at high temperature plays wetting action to the carbon containing thing, makes the carbon containing thing that cementability be arranged at normal temperatures, and therefore good heat-shock resistance is arranged; Because the not easy volatile of machine oil makes joint filler stable, so it has the characteristics of easy preservation.During construction with addition of industrial spirit with the joint filler dissolved dilution, its alcohol and resol are polar solvent, can increase the cementability of joint filler at normal temperatures, can improve its workability.
The present invention is described further below in conjunction with embodiment, but the present invention is not limited to these examples.
