Description
Technical field
The utility model relates to a kind of novel ladle porous core mounting structure.
Background technology
Along with steel industry depression, iron and steel enterprise is at cost efficiency by every means.Refractory material enterprise is the upstream supplier of steel industry, also will, by technological progress, reduce costs, and tides over the difficulties with iron and steel enterprise.
Air brick of steel ladle is that at the bottom of being installed on molten steel handbag, molten steel is stirred for blowing argon gas in position, makes non-metallic inclusion floating in molten steel, reduces impurity in steel, improves the functional refractory material of steel product quality.It is made up of brick cup and porous core, material is generally chrome corundum, corundum spinel prefabricated component, brick cup profile is cuboid or cylinder, inside opens a through hole that has a tapering, inlays a truncated cone-shaped porous core, inside there are several gaps, porous core outsourcing one deck stainless steel case, inlays and coordinates with brick cup, and porous core is generally in 25kg left and right, together with brick cup, in 100～200kg left and right, price is at 1500～3000 yuan/piece.In ladle use procedure, intermediate demand is changed once or twice.Be generally now two kinds substitute mode is installed.
1, overall built-in type
Be that porous core and brick cup are made entirety, be integral air brick.Building the bag end by laying bricks or stones when the liner of resistance to material, integral air brick cast setting, in the bag end, is made it to the height of resistance to material at the bottom of a little higher than bag, in the time using certain heat, air brick due to blowing argon gas can corrode than the resistance to material of cylinder-packing faster, need to change in advance, and must allow ladle stop using, roll off the production line cooling, be cooled to be applicable to people and enter the temperature of working in bag, then the castable of air brick periphery is manually removed with pneumatic tools, cast is installed after new air brick again, after toasting on request, then continue to use.This mode is more time-consuming, take manpower, the tool of taking a lot of work, Fei Naicai, the expense energy.
2, split fitted outside
Be that porous core and brick cup are split type, porous core appearance and size is to match with hole dimension in brick cup, is not an entirety.Building by laying bricks or stones or tie a knot the bag end when resistance to material, first brick cup is built by laying bricks or stones and be embedded in the bag end, make it and wrap the resistance to material in the end with high, drive a manhole in steel bottom, through-hole diameter is a bit larger tham porous core bottom external diameter, and at the air brick locking device that wraps end shell welded and installed steel.Before ladle uses, from outside, porous core is installed on to brick cup inner chamber, on porous core external diameter and brick cup, between inner chamber, use fire clay joint filling, and upwards compress bottom porous core with locking device, do not allow it get loose, the use of can reaching the standard grade.While using certain heat, still can not synchronize with the resistance to material of ladle liner, need to change porous core midway 1 time, but that ladle needn't roll off the production line is cooling, also needn't change brick cup, only need quick-replaceable porous core.The advantage of this mode be save time, laborsaving than overall built-in type, economize resistance to material, economize the energy.Shortcoming is that Renewal process easily causes damage to brick cup because having gap between brick cup and porous core, having potential safety hazard, also has potential safety hazard.
Summary of the invention
For solving the problems of the technologies described above, the utility model provides a kind of novel ladle porous core mounting structure, compared with prior art, the utlity model has.
For reaching above object, the technical scheme that the utility model adopts is:
A kind of novel ladle porous core mounting structure, comprise ladle shell, be covered with inner lining refractory material layer along ladle shell inwall, be directly embedded with in advance at least two porous cores under in the bottom of ladle shell, inner lining refractory material layer, without brick cup situation, the height of porous core is 400-500mm; The height difference of branched porous core, is height and arranges, and the porous core of upper level height is higher than next stage porous core height 100-120mm; Wherein the top of high porous core is higher than the diapire of inner lining refractory material layer, and remaining porous core is embedded in inner lining refractory material, and the diapire of each porous core is fixed on ladle shell diapire.
Further, described porous core is two.
Further, on described ladle shell, with the corresponding through hole that is provided with of central axis of porous core, be provided with fixed axis in through hole, the upper end via through holes of fixed axis stretches into through hole and is fixedly connected with porous core.
Operation principle of the present utility model and intentionally effect show:
The utility model is that two porous core height differ 100-150mm left and right, place by certain requirement and spacing at pre-buried branched porous core (not needing brick cup) simultaneously when resistance to material at the bottom of pouring ladle.Wherein first pre-buried height of porous core will be higher than the bag end thickness of resistance to material 20mm left and right, and second porous core will be embedded in the material feeding of bag bottom pour mold, and the pre-buried degree of depth is at 100mm～120mm.After ladle is brought into use, first use first porous core, after waiting and using certain number of times, wash away and corrode after certain depth through molten steel at the bag end, and second porous core just reveals, and then two porous cores can be used alternatingly, and synchronize and roll off the production line until use with ladle.
This utility model is to improve on the basis of first two mounting means, can change air brick midway, just can reach with the resistance to material of ladle and synchronize.
This technology is compared first two mode following advantage:
1, ladle use needn't remove midway, change air brick or porous core, has advantages of the refractory consumption rate of saving, saves labour, saves time, saves the instrument of unpacking.
2, because of ladle use in no longer stop to repair, do not need cooling, reduced thermal waste, also save ladle in repair rear baking link, save gas consumption, can significantly save the energy.
3, because two porous cores are integrated poured being embedded in advance in bag end castable refractory, there is not gap, use that therefore can be safe and reliable.
