[0002] The hot metal ladle is one of the key equipment in the casting process of cast pipes. The stability of its volume structure directly affects the flow rate of hot metal when the ladle is tilted at different angles, and further affects the finished size of the cast pipe. Aiming at the problem that the refractory bricks in the lining of the existing sector ladles for cast pipes are prone to iron leakage, the following three problems will occur:

[0003] (1) The containment shrinks, the lengths of the finished cast pipes are inconsistent, and the pipe walls are uneven;

[0004] (2) The ladle is red-hot, and there are great potential safety hazards in the production process;

[0005] (3) The service life of the hot metal ladle is short, the material consumption cost is high, and the labor intensity of manual repair is large. Summary of the Utility Model

[0006] The utility model provides a sector ladle with iron leakage prevention to solve the problem that the refractory bricks in the lining of the existing sector ladles for cast pipes are prone to iron leakage.

The two arc-shaped side bottoms of the ladle are respectively arranged on both sides of the arc-shaped middle bottom of the ladle. The outer contours of the arc-shaped middle bottom of the ladle and the two arc-shaped side bottoms of the ladle are matched. The arc-shaped middle bottom of the ladle is composed of multiple bricks that are lapped and matched with each other, and each arc-shaped side bottom of the ladle is composed of one brick.

[0012] Further, the side wall includes a front wall, a rear wall, a left wall, and a right wall. The front wall and the rear wall are both connected to the arc-shaped ladle bottom, and the left wall and the right wall are respectively connected to the corresponding arc-shaped ladle side bottoms.

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Those skilled in the art should know that the embodiments described below are part of the embodiments of the present disclosure, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0030] Various non-limiting embodiments of the present invention are described in detail below. Any number of elements in the accompanying drawings is for illustration and not for limitation, and any naming is only for distinction and does not have any limiting meaning. It should be noted that the embodiments and features in the embodiments of the present invention can be combined with each other without conflict.

[0031] like Figures 1-3 As shown, an anti-iron seepage fan-shaped ladle comprises a fan-shaped outer shell 1 and a fan-shaped ladle body arranged in the fan-shaped outer shell 1. Rotating shafts 2 are provided on both sides of the fan-shaped outer shell 1. The rotating shafts 2 are more convenient for lifting the fan-shaped ladle body, and then for tilting the fan-shaped ladle body to allow the molten iron in the fan-shaped ladle body to flow out.

[0032] Specifically, the fan-shaped enclosure fits the inner wall of the fan-shaped outer shell 1, and the fan-shaped enclosure is constructed by masonry of a plurality of bricks 3, and each brick 3 has an overlap portion 11 on the side, and the overlap portions 11 between two adjacent bricks 3 overlap and cooperate with each other to form a staggered and extended gap between bricks 3. The staggered and extended gap between bricks 3 can effectively extend the penetration path of molten iron, especially in the later stage of use, the performance of bricks 3 will inevitably decay, and the gap between bricks 3 will become larger. At this time, the "Z" path formed by the staggered and extended gap between bricks 3 can effectively hinder the penetration of molten iron, reduce the risk of molten iron penetration, increase the contact surface of bricks 3, and ensure the tightness between bricks 3.

[0033] like Figures 2-7 As shown, the fan-shaped bag body includes a bag bottom 12 and a side wall 13 overlapped with the bag bottom 12 .

[0034] Among them, the bottom of the ladle 12 includes an arc-shaped ladle insole 4 that overlaps and cooperates with the side wall 13 and two arc-shaped ladle side soles 5. The two arc-shaped ladle side soles 5 are respectively placed on both sides of the arc-shaped ladle insole 4. The outer contours of the arc-shaped ladle insole 4 and the two arc-shaped ladle side soles 5 match. The arc-shaped ladle insole 4 is composed of multiple bricks 3 that overlap and cooperate with each other, and each arc-shaped ladle side sole 5 is composed of one brick 3.

[0035] The side wall 13 includes a front wall 6, a rear wall 7, a left wall 9 and a right wall 8. The front wall 6 and the rear wall 7 are both connected to the arc-shaped ladle insole 4. The left wall 9 and the right wall 8 are respectively connected to a corresponding arc-shaped ladle side sole 5. The front wall 6, the rear wall 7, the left wall 9 and the right wall 8 are all built with multiple bricks 3. The adjacent bricks 3 are overlapped and cooperated with each other through the overlapping part 11 to form a misaligned and extended gap of bricks 3. The structures of the left wall 9 and the right wall 8 and the quantity and types of bricks 3 used are the same.

[0036] Among them, there is a ladle nozzle 10 on the rear wall 7 for the molten iron to flow out. The ladle nozzle 10 in this embodiment adopts a split masonry method, which is convenient for local replacement of the high-scouring part in the actual use process and reduces the material cost expenditure.

[0037] The sector ladle body is built with bricks 3 made of low creep clay material. During the process of loading, transporting and pouring molten iron, the sector ladle body is subjected to the combined action of high temperature of molten iron, scouring, mechanical wear and slag and iron chemical erosion. Especially when working alternately under high and low temperature conditions, its mechanical properties, physical and chemical properties, etc. will all decrease to a certain extent. And the longer the interval period between high and low temperature conditions, the more serious the damage degree in the sector ladle body, the gap between materials becomes larger, the penetration path of molten iron becomes wider, and the risk of penetrating the sector ladle body increases. Considering the particularity of the working environment of the molten iron ladle, the bricks 3 made of low creep clay material used in this embodiment have good high-temperature volume stability, creepability and wear resistance, and can better cope with the high-temperature environment.

[0038] There are four types of bricks 3 in this embodiment. The first type is the type of bricks 3 at the bottom of the ladle 12. The second type is the bricks 3 located at the central position. Four sides of this brick 3 all have overlapping parts 11. The third type is the bricks 3 located at the edge position. Three sides of this brick 3 all have overlapping parts 11. The fourth type is the bricks 3 located at the sharp corner position. Two adjacent sides of this brick 3 all have overlapping parts 11. The sector ladle body in this embodiment is built by the above four types of bricks 3.

[0039] In other embodiments, each side of each type of brick 3 can also have overlapping parts 11, but after masonry, some of the overlapping parts 11 are not used.
