Description
Technical field
The present invention relates to slag sluicing system equipment technical field in blast furnace casting process, more particularly, relate to the skimming equipment in a kind of blast furnace casting process.
Background technology
Blast furnace ironmaking is most widely used iron-smelting process, and mix through the high temperature liquid iron of blast-furnace smelting and slag and flowed out by iron mouth, molten iron is being transported to converter station by hot metal ladle, torpedo tank car after blast furnace casting, carries out converter steelmaking.In order to prevent the objectionable constituent in slag from again entering molten iron, in the process of blast furnace casting, slag sluicing system equipment is needed to be separated high temperature sludge iron.In prior art, the main slag sluicing system equipment adopted is skimmer, is also called sand mouth; Skimmer connects main trough of blast furnace, under connect iron runner, bypass connects slag runner, and in the process of tapping a blast furnace, the slag in main iron hook and molten iron are because of the different natural layering of its density.Slag floats over above molten iron because density is little, is blocked rear then flow to slag runner by skimmer; Molten iron because of below its density sinks to greatly, and flows to iron runner by the gap between skimmer and main iron hook.Realize the slag of high-temperature liquid state, effective separation of iron in process of tapping a blast furnace.Skimmer is in core node position on casting house, is the exclusive node ensureing that slag iron is effectively separated, and is the device promoting that in blast furnace casting process, high-temperature liquid furnace slag, molten iron are effectively separated.
But undergo the mechanical erosion of high temperature liquid iron in skimmer process under arms, the chemical erosion of high temperature furnace slag and intermittent thermal shock are corroded.And three kinds of factor alternating actions, mutually strengthen, greatly reduce the service life of skimmer.Existing skimmer generally adopts the materials such as corundum, silicon carbide, alumina powder and pitch to make, the antiscour of skimmer, corrosion resistance, antistrip performance and thermal shock resistance are poor, make to only have 1-2 month the work-ing life of skimmer, and often within 10-15 days, just need feed supplement once.The frequent repairing of skimmer, usually affects and taps a blast furnace on schedule, causes the checking underproduction, and coke ratio raises.
The work-ing life of existing skimmer is shorter, repairing is frequent, directly affects blast furnace and taps a blast furnace on schedule, extend molten iron and deposit the stove time, not only increase a ton iron cost, bring heavy economical load to iron and steel enterprise, and bring serious potential safety hazard.Therefore, need the material composition improving slag sluicing system equipment in blast furnace casting process badly, make skimming equipment have good antiscour, anti-scour property, thus improve the service life of skimming equipment.
Through patent retrieval, there is relevant technical scheme open.As: a kind of blast-furnace iron runner skimmer precast lintel (CN200910143657.2, Shen Qing Publication day: 2010-12-01), lintel refractory castable is prefabricated forms for it, and come into operation after overbaking, prefabricated component top future insufficiency, the problem that although this application case prevents precast lintel in use causes top tension to ftracture because bottom expanded by heating is elongated, extend skimmer work-ing life, but this application case only improves the structure of skimmer, it does not improve the material composition of skimmer, the service life of skimmer needs to be improved further.
In addition, a kind of blast furnace reclaimed sand mouth material and preparation method thereof (CN201210187866.9, Shen Qing Publication day: 2013-12-11), its component and weight percent content are: its component and weight percent content are: the discarded sial material 15-20% of granularity≤0.088mm, granularity is the quartz sand 20-30% of 1-3mm, the quartz sand 10-20% of granularity≤0.088mm, the clay powder 8-15% of granularity≤0.074mm, the pitch 3-10% of granularity≤1.0mm, the coke powder 7-15% of granularity≤2.0mm, the discarded iron runner material fine powder 10-20% of granularity≤0.088mm, non-hydrate sodium metasilicate: 0.1-3%.Although this application case reduces the production cost of skimming equipment, and make to be fully utilized containing the high alumina brick etc. of aluminium silicon material and iron runner material, the material composition of skimming equipment needs perfect further, and improves the service life of skimming equipment further.
