Abstract
The invention discloses an iron-storage type casting material for an iron tapping channel. The casting material is composed of brown corundum, dense corundum, silicon carbide, ball asphalt, alpha-Al2O3, pure calcium aluminate cement, silica micropowder, silicon metal powder, Guangxi white mud, aluminium metal powder, an explosion-proof fiber and FDN. The invention also provides a preparation method of the iron-storage type casting material for the iron tapping channel. The method comprises the steps of mixing the above-mentioned raw materials according to a proportion; stirring the mixture for 10 minutes in a stirring machine; discharging the mixture and packaging. Compared with a conventional technology, the method has the beneficial effects that the casting material is manufactured by employing Al2O3-SiC-C material and a carbon-containing polymer, and has good high-temperature wear resistance, good slag-resistant chemical corrosion performance, high and good oxidation resistance, good thermal shock-resistant stability, good high-temperature volume stability, good explosion resistance, high iron content, high safety coefficient and high slag resistance, sticks no slag iron, is convenient for production, and reduces labor intensity.
Description
[technical field]
The present invention relates to fire resisting material field, relate in particular to a kind of iron storage type casting house mould material and preparation method thereof.
[background technology]
At present, domestic single iron notch blast furnace, the structure of casting house is common employing bareing iron runner all, the AL that adopt on material more
2O
3-SiC-C matter iron runner ramming mass.The concrete steps of this method are: before the ramming, site clearing at first, remove residue iron in the ditch, with power tools such as pneumatic pick or drill rods, primitive groove is served as a contrast the remaining slag iron of working lining complete removal, with high pressure pipe particle, dust in the ditch are blown clean, during ramming, first ramming mass is poured in the ditch after cleaning out, to expect evenly to spread out and put on spade, with vibration-type electrorammer or pneumatic hammer layering ramming repeatedly, make the abundant vibration compacting of ditch material, one time layer thickness is about 200cm, after material is completed, ramming 5-7 time, until ramming is closely knit, can use.The running repair of middle process generally can be used 5-7 days.Along with improving constantly of the capacity factor of a blast furnace and the number of casts, its following shortcoming constantly appears, be tissue looseness, intensity low, do that oxidisability is poor, iron influx is low, an iron runner light maintenance in five days, an overhaul in ten days repeats to repair the ditch increased frequency, labour intensity is large, duration of service is short, often affects blast furnace and taps a blast furnace on schedule, and production is made troubles to blast furnace.
[summary of the invention]
The present invention is in order to solve above-mentioned deficiency, namely overcomes the deficiency that iron runner repeats to repair and duration of service is short, and a kind of iron storage type casting house mould material and preparation method thereof is provided.
