Abstract
The utility model belongs to the improvement of steel mill molten iron pack arrangement, particularly a kind of ladle with duckbill orifices, including the ladle with symmetrical gudgeon, its a diameter of 2 2.2 meters, it is highly 4 4.5 meters, duckbill orifices is set in ladle containment wall suitable for reading, the distance of ladle containment wall is stretched out for 0.8 1m in the duckbilled tip of its orifices, the A/F that duckbilled upper end is connected with ladle containment wall is 1.3 1.5m, and the height of orifices is 1 1.2m.The utility model is rational in infrastructure, can improve the flow regime that ladle converts hot metal charging to converter, improves the cold steel situation of bag mouth knot, reduces cold steel clearance time, reduces the labor intensity of workman, improves operating efficiency.
Description
Technical field
The utility model belongs to the improvement of steel mill molten iron pack arrangement, particularly a kind of molten iron with duckbill orifices
Bag.
Background technology
Foundry ladle is transported to converter by driving afterwards in accepting iron liquid before converter, is tumbled using crane by molten iron
Converter is added to be smelted.Ladle is wrapped in the process that hot metal charging is converted to converter at it can gradually be bonded a large amount of cold steel at edge, cold
Steel bonding volume can influence subsequently to use when larger, cause the molten iron inside ladle not pour out completely, and if cold steel
It can be fallen down by external force effect, potential safety hazard is caused to iron bag surrounding devices or personnel.Therefore, ladle bag is along cleaning work amount
Larger, frequently the cold steel of bag mouth knot can influence the normal turnover of ladle, influence normal production process.
Ladle is wrapped in the process that hot metal charging is converted to converter at it can gradually be bonded a large amount of cold steel at edge, cold steel is bonded volume
It can influence subsequently to use when larger, cause the molten iron inside ladle not pour out completely, and if cold steel is by outer masterpiece
With that can fall down, potential safety hazard is caused to iron bag surrounding devices or personnel.Therefore, ladle bag is larger along cleaning work amount, frequently
The cold steel of bag mouth knot can influence the normal turnover of ladle, influence normal production process, worker's labor intensity is higher, with compared with
High danger.
The subject matter of presence is as follows：
1st, former is circle using ladle bag mouthful, and molten iron flow is careless and sloppy when converting hot metal charging, easily cold in ladle bag mouthful knot
Steel.
2nd, when pulling out bag along cold steel, cold steel is easy to fall off phenomenon, and worker's operational danger is higher.
3rd, artificial multi-pass operation is needed, labor strength is larger.
4th, the cold steel frequency of ladle cleaning is higher, influences the turnover of ladle.
Utility model content
The purpose of this utility model is to provide a kind of ladle with duckbill orifices, and its is rational in infrastructure, can be with
Improve the flow regime that ladle converts hot metal charging to converter, improve the cold steel situation of bag mouth knot, reduce cold steel clearance time, reduce work
The labor intensity of people, improves operating efficiency.
What the purpose of this utility model was realized in：A kind of ladle with duckbill orifices, including with pair
Claim the ladle of gudgeon, its is a diameter of 2-2.2 meters, is highly 4-4.5 meters, duckbill is set in ladle containment wall suitable for reading
The distance of ladle containment wall is stretched out for 0.8-1m in orifices, the duckbilled tip of its orifices, and duckbilled upper end connects with ladle containment wall
The A/F connect is 1.3-1.5m, and the height of orifices is 1-1.2m.
Main improvement content is as follows：
On the basis of base iron takes all of shape bag mouthful, design and installation duck-beak type orifices, inside builds refractory material by laying bricks or stones, convenient
Molten iron is poured out, and easy stress when clearing up cold steel, cleaning speed is fast.
Improvement effect
1st, the ladle bag mouthful of new design is duck-beak type, and molten iron flow is concentrated when converting hot metal charging, it is not easy in ladle
The cold steel of bag mouth knot.
2nd, duck-beak type bag mouthful cold steel when pulling out bag along cold steel easily comes off, can remote operation, Ke Yibao using machinery
Hinder the safety of worker's operation.
3rd, it is less to the refractory material damage inside ladle, refractory material expense can be reduced, production cost is reduced.
4th, the frequency reduction of the cleaning cold steel of bag mouth, labor strength reduction.
4th, ladle clears up cold steel frequency reduction, can ensure the normal turnover of ladle.
The utility model is rational in infrastructure, improves the flow regime that ladle converts hot metal charging to converter, improves bag mouth knot
Cold steel situation, reduces cold steel clearance time, reduces the labor intensity of workman, improve operating efficiency.
Brief description of the drawings
The utility model is further described below in conjunction with accompanying drawing, Fig. 1 illustrates for the utility model front view structure
Figure, Fig. 2 is the utility model overlooking the structure diagram.
Embodiment
A kind of ladle with duckbill orifices, as shown in Figure 1 and Figure 2, including the ladle with symmetrical gudgeon 2
1, its is a diameter of 2-2.2 meters, is highly 4-4.5 meters, duckbill orifices 3 are set in the containment wall suitable for reading of ladle 1, and it is noted
The distance that the containment wall of ladle 1 is stretched out at the duckbilled tip of head piece 3 is 0.8-1m, the opening that duckbilled upper end is connected with the containment wall of ladle 1
Width is 1.3-1.5m, and the height of orifices 3 is 1-1.2m.
Claims (1)
1. a kind of ladle with duckbill orifices, including the ladle (1) with symmetrical gudgeon (2), its a diameter of 2-
