Abstract
The utility model discloses a floss barrier for an iron material mixing apparatus, particularly a floss barrier for a torpedo iron material mixing apparatus. The main body of a floss barrier (1) is a cuboid, and two semicircular iron holes with the radius of from 140 mm to 220 mm are arranged on a front and a back vertical planes by taking respective vertical symmetry axis as a central line. Fireproofing material which is coated outside the iron core of the floss barrier (1) is high alumina casting material, and the specific gravity of the whole floss barrier is in the range of from 3.0 to 3.5 t/m<3>. The floss barrier which is matched with the inner shape of an iron material mixing apparatus can be used for thicker floss layers, has good floss barrier effect which can reach more than 85%, and can completely satisfy the requirements for steel production.
Description
The utility model relates to a kind of metal mixer car slag-blocking apparatus, specifically a kind of slag-blocking apparatus that is used for fish torpedo type iron mixing vehicle.
The slag-blocking apparatus that is used for fish torpedo type iron mixing vehicle in the prior art is to introduce from Japan when introducing fish torpedo type iron mixing vehicle, and its structure as shown in Figure 4.Mainly form by slag stopper 1, chain sling 2, mounting rod 3 and support 5.Two supports 5 are installed in metal mixer car 6 Che Kou both sides respectively, have the circular mounting hole on it.Slag stopper 1 is made by iron core outsourcing refractory materials, main body be one up and down for curved surface, all the other for the hexahedron of the vertical guide that intersects vertically in twos, have two symmetrically arranged right cylinder 1a on four sides on two vertical guides of both sides.Chain sling 2 is lifted on mounting rod 5 middle parts with slag stopper 1.Mounting rod 5 is made by steel pipe.During use, by suspension ring on the mounting rod 34 slag-blocking apparatus is sling, put slag stopper 1 and enter metal mixer car 6, mounting rod 3 two ends are inserted in the circular mounting hole of support 5 by crane.Metal mixer car 6 fascinates when tapping a blast furnace, and slag stopper 1 keeps off the bits on molten iron 8 liquid levels 7 in metal mixer car 6.Existing weak point is: shape does not match in slag stopper and the metal mixer car, and when metal mixer car tapped a blast furnace, molten iron was not the middle part from slag stopper, but flows out from both sides, usually molten iron is poured into outside the hot metal ladle.In addition, slag stopper is that iron core outsourcing clay casting material is made, and proportion is little, has only 2.781/m
3, and the proportion of slag can reach 2.9t/m
3, after slag blanket was thicker, particularly carries out hot metal pretreatment, slag stopper is heavy can only to float on the top of the slag less than in the slag, does not have the effect of pushing off the slag at all.
The purpose of this utility model provides a kind of, and shape is complementary, can be suitable for the metal mixer car slag-blocking apparatus that thicker slag blanket uses in slag stopper shape and the metal mixer car, taps a blast furnace to realize the few slag of metal mixer car even not have slag, satisfies the requirement of STEELMAKING PRODUCTION.
The purpose of this utility model can realize by following measure.The slag stopper main body is a rectangular parallelepiped, before and after it on two vertical guides, is medullary ray with separately vertical symmetry axis, has the semicircle iron notch of two radius R=140～200mm, and molten iron can be flowed out in the middle of slag stopper.The refractory materials of slag stopper iron core outsourcing is the high alumina casting material, and whole slag stopper is that proportion is 3.0～3.5t/m
3, greater than the proportion of slag.
One its axial line and the vertical right cylinder of this face are arranged in the middle of the upper horizontal surface of slag stopper, and its upper end has the connection steel plate.Chain sling is lifted on the mounting rod middle part by connecting steel plate with slag stopper, and chain sling is not directly contacted with slag and molten iron.On the mounting rod of making by steel pipe, except that two ends as all being surrounded by refractory materials the part that is installed on support, make it can be crooked because of the thermal radiation of molten iron, influence the work-ing life of whole slag-blocking apparatus.Support is provided with the upper shed mounting groove, and the mounting groove that only needs during installation the two ends of the mounting rod that hangs slag stopper to be put into from top to bottom support gets final product.
The advantage that the utility model is compared with prior art had is: shape is complementary in slag stopper and the metal mixer car, can be suitable for thicker slag blanket and use, and pushing off the slag is effective, reaches more than 85%, can satisfy the requirement of STEELMAKING PRODUCTION fully.Simple in structure, easy to use, can reach work-ing life 40～70 times, be 6-10 times of former slag-blocking apparatus.
Description of drawings:
Fig. 1 is the structure iron of the utility model metal mixer car slag-blocking apparatus.
Fig. 2 is the A-A sectional view of Fig. 1.
Fig. 3 is the B-B sectional view of Fig. 1.
Fig. 4 is the structure iron of metal mixer car slag-blocking apparatus of the prior art.
Below in conjunction with accompanying drawing embodiment of the present utility model is done detailed argumentation.
The utility model metal mixer car slag-blocking apparatus mainly is made up of slag stopper 1, chain sling 2, mounting rod 3 and support 5 as shown in Figure 1, 2.Two supports 5 are installed in the both sides of metal mixer car 6 car mouths respectively, and it is provided with the upper shed mounting groove, sees Fig. 3.Slag stopper 1 is 2.5t/m by iron core outsourcing volume density
3The high alumina casting material make, the proportion of whole slag stopper is 3.19t/m
3The main body of slag stopper 1 is a rectangular parallelepiped, has on two vertical guides of both sides before and after two symmetrically arranged right cylinder 1a on two vertical guides, and be medullary ray with separately vertical symmetry axis, have the semicircle iron notch of two radius R=160mm; One its axial line and the vertical right cylinder 1b in this plane are arranged in the middle of the upper horizontal surface, and its upper end has and connects steel plate 1c.Chain sling 2 is lifted on mounting rod 3 middle parts by connecting steel plate 1c with slag stopper.On the mounting rod of making by steel pipe 3, except that two ends as all being surrounded by refractory materials the part that is installed on support 5.Mounting rod 3 middle parts, there are suspension ring 4 top relative with chain sling 2 is installed.
During use, by suspension ring 4 slag-blocking apparatus is sling, put slag stopper 1 and enter metal mixer car 6, mounting rod 3 two ends are put into the upper shed mounting groove of support 5 by crane.At this moment, the part of slag stopper 1 floats over more than the top of the slag of slag 7, and a part sinks to slag 7 the insides, and its horizontal surface is in slag 7 and molten iron 8 separation surfaces, sinks to slightly in the molten iron 8.Along with fascinating of metal mixer car 6, a lower edge that has the vertical guide of semicircle iron notch of slag stopper 1 comes to the lower edge of metal mixer car 6 car mouths.Turning angle strengthens gradually, and molten iron 8 is flowed out by the semicircle iron notch at slag stopper 1 middle part.Begin to have some former bits 7 that are stored in semicircle iron notch place, a large amount of subsequently molten iron 8 flow out, and bits 7 are blocked in the metal mixer car 6.
When metal mixer car 6 when other direction fascinates, molten iron 8 is flowed out by the circular iron notch of second half of slag stopper 1, satisfies the needs that fascinate and tap a blast furnace in fish torpedo type iron mixing vehicle 6 two sides.
