Abstract
The casting house mould material, adopting brown corundum is main raw material, suitably allocates carborundum, carbonaceous material, clay, high-alumina cement, super-fine powder, admixture into and makes.Its ratio range (weight percent) is brown corundum 60～80, SiC10～30, clay 1～5, high-alumina cement 2～5, super-fine powder 1～5, admixture 0.3～1.0.With bauxite clinker instead of part palm fibre corundum, can further reduce cost.This mould material raw material is easy to get, and is with low cost, easy construction, long service life.
Description
The present invention relates to the material of iron-smelting blast furnace casting house.
At present, domestic blast furnace iron outlet groove all adopts ramming mass, and work-ing life is short, and iron influx only has several kilotons, repairs frequently in the use, and labour intensity is big, and environmental pollution is more serious; External Refractory Castables for BF Troughs and Runners, main raw material are to adopt low pore fused corundom or high-purity mullite, and work-ing life is longer, but the cost height, domestic raw material sources anxiety.
The purpose of this invention is to provide a kind of suitable China's national situation, raw material sources are convenient, and cost is low, the Refractory Castables for BF Troughs and Runners that work-ing life is also long.
It is main raw material that the present invention adopts brown corundum, suitably allocates carborundum, carbonaceous material, clay, high-alumina cement, super-fine powder, admixture into and makes.Its ratio range (weight percent) is, brown corundum 60～80, and SiC 10～30 clays 1～5, high-alumina cement 2～5, super-fine powder 1～5, admixture 0.3～1.0(adds).
If with bauxite clinker instead of part palm fibre corundum, can further reduce cost, the weight percent of each component is brown corundum 20～40, bauxite clinker 30～60, SiC 5～30, C 2～10, clay 1～5, high-alumina cement 2～5, super-fine powder 1～5, admixture 0.3～1.0(adds).
In the above component, carbonaceous material can be selected one or both among Graphite Powder 99, electrode powder, the coke powder for use.High-alumina cement is done setting accelerator.Super-fine powder can be selected Al for use

5Deng among one or both.Admixture can be selected one or both and the metallic aluminium powder preparation among trisodium phosphate, tripoly phosphate sodium STPP, Sodium hexametaphosphate 99, Sodium salts humic acids, SN water reducer, the ST water reducer etc. for use.
The use of super-fine powder and admixture, purpose are the mould material that obtains low moisture, high-strength compact, and make its rapid drying and do not ftracture and peel off, and prolong the work-ing life of mould material.
Mould material provided by the invention not only raw material is easy to get, and is with low cost, easy construction, and good anti-slag iron etch ability and thermal shock resistance energy are arranged, and be difficult for dry slag iron, be easy to advantages such as cleaning.Be greatly improved than the ramming mass of domestic employing work-ing life, suitable with the mould material of external employing fused corundom.Be not only applicable to blast furnace iron outlet groove, be applicable to other molten metal chute yet.For the newly built and improved large and medium-sized blast furnace of China, use this mould material to do casting house, can satisfy high temperature blast, high top pressure operation, the many and fast requirement of flow velocity of slag iron amount.
Embodiment 1: each component prescription (weight percent) is, brown corundum 75, and SiC 15, carbon material 3, clay 4, high-alumina cement 2, SiO
2Super-fine powder 1, admixture (tripoly phosphate sodium STPP, Sodium salts humic acids and metallic aluminium powder preparation) 0.5(adds).With 4 * 4 * 16cm die trial casting, survey its performance, the results are shown in subordinate list.
Each components prescription (weight percent) of embodiment 2. are, brown corundum 24, and bauxite clinker 51, SiC 14, carbon material 4, clay 4, high-alumina cement 2, SiO
2Super-fine powder 1, admixture (tripoly phosphate sodium STPP, Sodium salts humic acids and metallic aluminium powder preparation) 0.45(adds).With 4 * 4 * 16cm die trial casting, survey its performance, the results are shown in subordinate list.
The main casting house and the swing chute of 1327 cubic metres of blast furnaces of mould material construction of the prescription making of embodiment 3. usefulness embodiment 1, through industrial application more than a year, total iron influx has reached more than 500,000 tons, and result of use is fine, at present still in continuation is used.Mould material ditch lining compares with former ramming mass, refractory consumption rate has reduced by 70～80%, ton iron cost has reduced by 30～40%, easy construction, labour intensity is low, has eliminated pollution, has improved the stokehold operating environment greatly, satisfy the needs of blast furnace strengthening smelting, obtained good economic benefit and environmental benefit.
