Abstract
The utility model discloses a protection and molten steel guider are annotated to combination formula bale, belong to metallurgical continuous casting equipment. The device consists of a protective sleeve 1 which is filled with liquid and a flow guide brick 2 which is built at the impact point of a large ladle at the bottom of a tundish 6, wherein the bottom of the protective sleeve 1 is provided with a steel tapping hole 5. When the large ladle is filled with the molten steel, the molten steel flows upwards through the steel outlet 5 under the action of the flow guide bricks 2 through the protective sleeve 1. The utility model can reduce the secondary oxidation degree of the ladle pouring stream and the air, reduce the inclusion and reduce the entrainment of the tundish slag, and is convenient for the inclusion to float and tap the steel stream surface.
Description
The utility model is big bag beam protection of combined type and molten steel guider, belongs to metallurgical continuous casting equipment.
In continuous casting production process, wrap beam unprotect cast greatly and cause the molten steel secondary oxidation, wrap beam greatly to slag in the tundish--steel drift hit cause a large amount of in the middle of cinder inclusions to be involved in the molten steel be the main source of field trash in the strand.In order to solve this class problem, people adopt following measure: (1) is wrapped beam greatly and is added long nozzle or blown inert gas protection cast; But this method needs the numerous and diverse devices of a cover such as manipulator, operation inconvenience, and general factory is difficult to realize.(2) build barricade in the tundish, change the molten steel flow direction, but be not easy to build barricade in the tundish that has.
The purpose of this utility model provides big bag beam protection of a kind of combined type and molten steel guider, and it partly is made up of protective casing and water conservancy diversion brick.It can be those and is not easy to install big bag adds long nozzle and build barricade in tundish conticaster and provides and reduce that field trash produces in the molten steel, promote inclusion floating, thereby improves continuous casting billet quality.
The utility model is realized in the following way:
The protective casing that allows beam pass through when wrapping beam greatly, big bag shock point block has the water conservancy diversion brick in the tundish bottom, and two parts are fire resistive material product, and the interface connection is arranged between the two.The protective casing bottom has tapping hole, and beam is by protective casing, and steel flows by tapping hole to the upper reaches under the effect of water conservancy diversion brick.
Below in conjunction with accompanying drawing the utility model is described:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the AA view of Fig. 1.
Fig. 3 is a fundamental diagram of the present utility model.
Big bag beam protection of combined type of the present utility model and molten steel guider are made up of garden tubular protective casing 1 and block wrap the shock point place greatly in tundish 6 bottoms water conservancy diversion brick 2, and two parts are fire resistive material product.Connect with interface 12 between protective casing 1 and the water conservancy diversion brick 2.
The bottom of protective casing 1 has tapping hole 5, and tapping hole adopts rectangle better, also can be abnormity.Highly be 80～120mm, tapping hole quantity is 2～6, but 3 optimum, and the tapping hole direction should be avoided the middle water containing opening direction.
Suitable for reading 4 of protective casing 1 also can adopt tubaeform, and angle beta is 0～45 °.
The garden periphery of water conservancy diversion brick 2 can have been built fin 9, and the corner angle α of fin 9 is 0～80 °.
The each several part size of protective casing 1 and water conservancy diversion brick 2 is as follows:
The outer diameter D 1 of protective casing 1 is 100～500mm, littler better, the not serious steel that spatters is advisable during with big bag beam.
The height H of protective casing 1 is 600～1800mm, and its height is between at the bottom of the tundish and between the big water-coating port, as far as possible near big water-coating port.
The diameter D2 of water conservancy diversion brick 2 is 250～800mm, decides according to size at the bottom of the tundish and water conservancy diversion brick weight.
The thickness H1 of water conservancy diversion brick 2 is than tundish base thickness 0～50mm, between 50～150mm.
The height H 2 of the fin 9 of water conservancy diversion brick is 0～300mm.
If need big bag beam is sealed fully, an inflatable mouth is opened in a part that can be higher than the tundish degree of depth on protective casing 1 top, is blown into protective gas from inflatable mouth beam is sealed.
As shown in Figure 3, when wrapping 10 beams greatly, beam 11 is by protective casing 1, and steel stream passes through tapping hole 5 to upper reaches (as shown by arrows) under the effect of water conservancy diversion brick 2.Thereby play the secondary oxidation that reduces or eliminates beam and air; Avoid beam and impact middle cinder inclusion liquid 7 and middle cinder inclusion is involved in the molten steel 8, change the effect that the interior molten steel flow regime of tundish promotes the molten steel inclusion floating.
The utlity model has following effect:
1) alleviates the secondary oxidation degree of big bag beam and air, if lead to a small amount of inert gas seal, can solve the secondary oxidation problem of big bag beam and air fully;
2) can solve and unwrap greatly when watering beam to the erosion purposes of unsintered tundish insulating board, Reduce the field trash that heat-insulating shield erosion thing causes in the tundish first stove strand;
3) alleviate big bag beam to slag in the tundish--the impingement mix effect of steel, reduce being involved in of Tundish Slag;
4) change molten steel flow regime in the tundish, be convenient to steel inclusion come-up tapping stream interface.
