Abstract
The utility model relates to the field of steel slag hot-disintegrating processes, in particular to an inner-wall steel billet fixing device of a slag disintegrating pond, comprising lining plate steel billets. The steel billet fixing device of slag disintegrating pond is characterized in that two oppositely arranged lining plate steel billets are connected to both ends of a plurality of stressed rods, and the heads of the stressed rods are supported on the wall of the slag disintegrating pond; high temperature-resistance concrete layers are arranged among the lining plate steel billets and the wall of the slag disintegrating pond; the stressed rods are round steel with the diameter of 15-300 mm; and the tops of the high temperature-resistance concrete layers are provided with cover plates. Compared with the prior art, the inner-wall steel billet fixing device has the advantages that the inner-wall steel billet fixing device avoids the phenomenon that the lining plate steel billets deform and dump towards the inner side in cold-hot alternating environment so that the service life of the lining plate steel billets is obviously prolonged; as the cover plates are additionally arranged, the inner-wall steel billet fixing device can prevent high-temperature steel slag from splashing among the steel billets and the pond wall and simultaneously solves the problem that the steel billets are downwards extruded to dump by heat-insulating layers; and the device has convenient installation, simple maintenance and low cost.
Description
Technical field
The utility model relates to the steel slag hot disintegrating technology field, relates in particular to a kind of vexed slag bath inwall steel billet stationary installation.
Background technology
At present in the vexed technology of bessemer furnace slag heat, pour molten steel slag into vexed slag bath, the heat of fetching water is vexed, around the vexed slag bath inwall with certain thickness steel billet as liner plate, protect concrete-pool-wall.Because the molten steel slag temperature is more than 1400 ℃, and along with the cooling of slag temperature during fetching water, the temperature of slag bath liner plate also changes thereupon, under the situation that colds and heat succeed each other repeatedly, it is crooked to the inside that steel billet can produce distortion, comes off at last and topple over, and makes slag bath can't continue to use.
The fixing means that adopts is fixing with bolt and steel billet welding at present; or steel billet hung on the hook at one end be embedded in the pool wall; filling slag protection pool wall between steel billet and the pool wall is not scorched by high temperature; though this method temporarily can be fixed liner plate; but work-ing life is very short, and the stress that is pulled outwardly during the steel billet expanded by heating is under the alternate repetition; steel billet is have more than is needed how long will gross distortion, topples over to the inside.
Summary of the invention
The purpose of this utility model provides a kind of vexed slag bath inwall steel billet stationary installation, under situation about colding and heat succeed each other, can effectively fix vexed slag bath liner plate, and the liner plate steel billet life-span is obviously improved, and easy for installation, easy to maintenance.
For achieving the above object, the utility model is achieved through the following technical solutions:
Vexed slag bath inwall steel billet stationary installation comprises the liner plate steel billet, it is characterized in that, two blocks of liner plate steel billets that the opposite is provided with are connected some stressed member two ends, and the stressed member head withstands on the vexed slag bath wall.
Be provided with the refractory concrete layer between described liner plate steel billet and the vexed slag bath wall.
Described stressed member is diameter 150～300mm round steel.
Described refractory concrete top is provided with cover plate.
Compared with prior art, the beneficial effects of the utility model are: avoided cold and heat succeed each other the distortion under the environment of liner plate steel billet, the phenomenon of toppling over to the inside, the liner plate steel billet life-span is obviously improved, set up cover plate and can prevent that the high temperature slag from splashing between steel billet and the pool wall, solved thermofin simultaneously and pushed the problem that steel billet makes it to topple over downwards, this device is easy for installation, easy to maintenance, with low cost.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the side-view of Fig. 1.
Among the figure: the vexed slag bath wall of 1-2-liner plate steel billet 3-round steel 4-refractory concrete layer 5-cover plate
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described further:
See Fig. 1, Fig. 2, vexed slag bath inwall steel billet stationary installation comprises liner plate steel billet 2, and two blocks of liner plate steel billets 2 that the opposite is provided with are connected some diameter 150～300mm round steel 3 two ends, and 150～300mm round steel, 3 heads withstand on the vexed slag bath wall 1.Be provided with refractory concrete layer 4 between described liner plate steel billet 2 and the vexed slag bath wall 1, refractory concrete layer 4 top are provided with cover plate 5.
Installation process of the present utility model is as follows: 1) width and the identical groove of round steel 3 diameters are cut out in two liner plate steel billet 2 tops that are provided with at first over there, and semicircle is cut in the below, and the part that will scale off keeps.The round steel 3 of 2～5 diameter 150～300mm is placed in the groove that cuts, then the unnecessary place of the part that scales off is removed and welded together again, in the middle of round steel is wrapped in the lower section steel billet.Round steel 3 heads withstand on the vexed slag bath wall 1 of both sides, with round steel 3 and liner plate steel billet 2 contact part firm welding, when liner plate steel billet 2 is heated outwards expansion, round steel 3 also expands simultaneously and stretches, the vexed slag bath wall 1 that withstands the both sides, next door makes the liner plate steel billet 2 at four sides all be subjected to inside extruding, to offset outside expansion stress.
2) between vexed slag bath wall 1 and liner plate steel billet 2, insert 30～100mm refractory concrete layer 4 then as thermofin; the thick steel cover plate of 5～15mm is set above refractory concrete layer 4; promptly protected vexed slag bath wall 1 to prevent from again to turn over that the high temperature slag advances to splash between liner plate steel billet 2 and the vexed slag bath wall 1 in the slag process, solved thermofin simultaneously and pushed the problem that steel billet makes it to topple over downwards.
The utility model has the advantages that: 1, withstand pool wall with round steel, the liner plate steel billet around the extruding makes it fixing and evenly transmits distortional stress; 2, between liner plate steel billet and pool wall, fill refractory concrete layer thermal insulation layer, prevent that high temperature from damaging pool wall; 3, above refractory concrete layer thermal insulation layer, add cover plate, can prevent from spattering slag and directly contact with concrete-pool-wall, shorten the pool wall life-span.
