Description
Technical field
The utility model relates to a kind of continuous casting of molten steel intermediate tank stopper hole hermetically-sealed construction, especially a kind of continuous casting of molten steel intermediate tank stopper hole hermetically-sealed construction being applied to continuous casting of iron and steel technical field.
Background technology
Continuous casting technology is strand new technology liquid metals being cast into continuously certain section configuration through one group of special cooling and bracing or strutting arrangement, the steel ingot-first roll process dominated since its appearance fundamentally changes a century
[1].Continuous casting steel machine has the plurality of advantages such as production process simplifies, recovery rate of iron is high, energy resource consumption is low, automaticity is high, productivity ratio is high, slab quality is good compared with noting steel technique with traditional mould, becomes development of iron & steel industry and has one of important technology of epoch-making property in history.The development & application of continuous casting steel machine technology is technological revolution great again after relaying oxygen coverter produced by iron and steel, is the most active branch of current field of metallurgy, is also one of technology with fastest developing speed in field of steel-making.Continuous casting technology creates huge motive force to world steel industrial expansion.Current continuous casting production fast development has become promotion steel-making and flourish major technique power produced by whole iron and steel.
In continuous casting steel machine process, pans connect the container holding molten steel between steel ladle and crystallizer, has the functions such as decompression, shunting, removal of inclusions and storage molten steel, can realize sequence casting.At present, pans control the mode that molten steel enters crystallizer the modes such as stopper control, metering nozzle, slide plate.Control device for stopper mainly comprises mechanism, pull bar, stopper, controls the opening degree between stopper and pans immersion water gap bowl portion with hydraulic pressure or electronic mode, reaches and controls the object that molten steel enters crystallizer flow, as shown in Figure 1.Pans need to carry out preheating before for pouring molten steel, and in warm, flame is scurried out from stopper hole, directly carry out high temperature sintering to mechanism, pull bar, cause mechanism, pull bar oxidation, distortion, make mechanism, pull bar significantly reduces service life.Simultaneously because flame is scurried out from stopper hole, cause thermal loss large, add coal gas and air consumption, add energy resource consumption.In casting process, because of pull bar oxidation necking down, pull bar is connected loosening with stopper, cause molten steel to enter the instability of flow of crystallizer, crystallizer molten steel surface is fluctuated, causes slag, reduce slab quality, cause the serious accidents such as crystallizer spill and leakage steel time serious, greater impact is caused to organization of production.Therefore often taking to change in advance the measure of pans when occurring that pull bar to be connected situation about loosening with stopper, reducing pans continuous casting furnace number.But in actual production, the factor causing crystallizer molten steel surface to fluctuate is a lot, pull bar is connected with stopper and whether looseningly not easily judges to there is greater risk.Therefore, when also not having one effectively can stop pans preheating in prior art, flame is scurried out, and the effectively heat radiation of molten steel during isolation cast, anti-locking mechanism and pull bar oxidation distortion, significantly reduce the continuous casting of molten steel intermediate tank stopper hole hermetically-sealed construction of energy resource consumption.
Utility model content
Technical problem to be solved in the utility model is to provide flame when one effectively can stop pans preheating and scurries out, the heat radiation of molten steel during effective isolation cast, anti-locking mechanism and pull bar oxidation distortion, significantly reduce the continuous casting of molten steel intermediate tank stopper hole hermetically-sealed construction of energy resource consumption.
For solving the problems of the technologies described above the continuous casting of molten steel intermediate tank stopper hole hermetically-sealed construction that the utility model adopts, comprise pans, cover, pull bar and stopper, described cover is arranged on pans, described cover is provided with perforate, described pull bar is connected with stopper, described stopper is filled in pans from tapping, also comprise sealer, described sealer is made up of sealing cone and pallet, described sealing cone is set on stopper, one end that described sealing cone diameter of section is little is stretched into pans from tapping, the edge conjunction of described pallet and the large one end of sealing cone diameter of section, described pallet is taken and is placed on cover.
Further, described sealer is Split type structure.
Further, described pallet is the disk that centre cuts out a rounded face.
Further, the pallet of described sealer is provided with hand handle.
The beneficial effects of the utility model are: after adopting the hermetically-sealed construction of the application, outside pull bar is isolated in, bake process Flame directly can not contact with pull bar and plug rod mechanism transverse arm, in pouring molten steel process, decrease molten steel heat radiation simultaneously, slow down plug rod mechanism, pull bar oxidation necking down and distortion, reduce plug rod mechanism, pull bar use cost, and reduce energy resource consumption; Guarantee crystallizer molten steel surface is stablized, and reduces the pollution to molten steel, improves Cleanliness of Molten Steel; Avoid crystallizer spill and leakage steel; Increase pans continuous casting furnace number.
