Description
One, technical field:
The invention belongs to fire resisting material field, particularly relate to a kind of alumina-silicon carbide-carbon brick for torpedo tank and torpedo tank lining structure therewith.
Two, background technology:
At present, adopting aluminum-silicon carbide brick mostly at the refractory brick of iron ladle, torpedo tank liner working lining (is Al
2O
3-SiC-C brick is called for short the ASC brick), there is following main drawback in this brick: oxidation-resistance is poor, oxidation deactivation easily in the use, cause slag line and wash away the position corrode fast, dry slag is serious, difficult in maintenance; The low and middle-grade brick life-spans are low, and life-span 〉=1000 time required high-grade Al
2O
3-SiC-C brick costs an arm and a leg, the cost height.The application number of having authorized a kind of burnt aluminum-carbon brick for torpedo hot metal mixer car that has been 01126576.0 patent disclosure begins to adopt at the working lining of some metal mixer car, and the shortcoming of this aluminum-carbon brick is that anti-molten iron and slag action are poor, and the slag line district life-span is low, the running cost height.
In recent ten years, along with the raising of steel quality, the hot metal pretreatment technology has obtained development rapidly at home and abroad.The applicant began to carry out the research of torpedo jar with refractory materials in 1989, and nineteen ninety has been developed fish torpedo type iron mixing vehicle Al
2O
3-SiC-C brick, this brick is at first applied at Shoudu Iron and Steel Co, on 150 tons of fish torpedo type iron mixing vehicles of Shoudu Iron and Steel Co, use, after progressively expand to again on 260 tons of metal mixer cars and use.So far used Al altogether from 1991
2O
3Ton surplus the-SiC-C brick 50000, Shoudu Iron and Steel Co iron work fish torpedo type iron mixing vehicle is owing to use Al
2O
3-SiC-C brick, furnace life is significantly improved, increase to 1000 by original less than 300 stoves surplus stove, reached more than original 3 times, obtained remarkable economic efficiency.But the second half year in 2005, the change (in blast furnace molten iron process, adding fluorite) of (head moves, the first Qin) smelting technology because Shoudu Iron and Steel Co and Shoudu Iron and Steel Co resettlement factory to reach the purpose of purifying molten iron quality in advance, after making that molten iron that blast furnace discharges enters the torpedo jar, the composition of the slag of bringing into is bigger, erosion to torpedo tank liner is just relatively more serious, in the torpedo jar, also to add certain three in addition and take off agent and carry out three and take off processing, so just more aggravate erosion torpedo tank liner.Therefore, present several supply of material producer's supply Shoudu Iron and Steel Co and the Shoudu Iron and Steel Co resettlement used Al of factory
2O
3-SiC-C brick, result of use all relatively poor (less than 500 stoves), reduce than in the past work-ing life half or more, for this reason, develop the novel refractory that adapts to Shoudu Iron and Steel Co and resettlement factory torpedo jar usefulness, the product innovation that improves its work-ing life is imperative.In April, 2006, our factory is successfully developed the new generation product that adapts to Shoudu Iron and Steel Co and resettlement factory torpedo jar usefulness.
