Abstract
The utility model provides an asymmetric ladle be built by contract, it includes the lid, the lid periphery is equipped with the lid edge that can cover the ladle package edge, the bottom surface on lid edge is higher than the bottom surface of lid, it is equipped with a breach to cover corresponding ladle package mouth department along last, is equipped with the covering lid in this breach, the bottom surface of covering lid is higher than the bottom surface on lid edge, all be equipped with refractory material in lid, lid edge and the covering lid. The utility model discloses utilize the different depths of each position of be built by contract to improve the leakproofness of be built by contract, reduce slag and molten steel along the package with the package mouthful influence that the caking degree difference brought that solidifies. The heat-dissipation-preventing protection plate on the outer side of the ladle cover has better high temperature resistance and thermal shock resistance, can further reduce radiant heat loss and smoke overflow, completely seals the ladle cover and the ladle, reduces the temperature drop of molten steel, and is beneficial to reducing the final temperature of the converter.
Description
Technical Field
The utility model belongs to the mechanical equipment field relates to an asymmetric ladle be built by contract.
Background
In the production turnover processes of steel receiving, slag pouring and the like of the steel ladle, steel slag and cold steel can be inevitably adhered to the ladle edge and the ladle opening, and the accumulation at the ladle opening is particularly obvious. The whole thickness of the ladle cover used in daily life is the same and bilateral symmetry, when a certain amount of steel slag cold steel is attached to the ladle edge and the ladle opening, the ladle cover can not be completely sealed, radiation heat loss and smoke overflow are caused, and the working environment of workers is deteriorated.
SUMMERY OF THE UTILITY MODEL
The technical problem to be solved is as follows: to the technical problem, the utility model provides an asymmetric ladle be built by contract. The outer side of the ladle cover is additionally provided with the anti-heat-dissipation protective plate, the ladle edge and the ladle opening are staggered with different heights in the middle, and the ladle edge and the ladle opening are large and small in depth. The design reduces the radiation heat loss of the refractory material lining of the ladle and the molten steel, saves energy, reduces emission, protects environment and reduces consumption.
The technical scheme is as follows: the asymmetric ladle cover comprises a cover body, wherein a cover edge capable of covering a ladle edge is arranged on the periphery of the cover body, the bottom surface of the cover edge is higher than the bottom surface of the cover body, a notch is arranged on the cover edge corresponding to the ladle opening, a ladle opening cover is arranged in the notch, the bottom surface of the ladle opening cover is higher than the bottom surface of the cover edge, and refractory materials are arranged in the cover body, the cover edge and the ladle opening cover.
An inverted Y-shaped anchoring part is arranged in the cover edge.
An inverted Y-shaped anchoring part is arranged in the bag opening cover.
And the outer wall of the cover edge and the outer wall of the bag cover are both provided with heat-dissipation-preventing protective plates.
And the cover body is provided with a reinforcing rib for fixing the bag opening cover.
Has the advantages that: the utility model discloses utilize the different depths of each position of be built by contract to improve the leakproofness of be built by contract, reduce slag and molten steel along the package with the package mouthful influence that the caking degree difference brought that solidifies. Meanwhile, the heat-dissipation-preventing protection plate on the outer side of the ladle cover has better high temperature resistance and thermal shock resistance, and can further reduce radiant heat loss and smoke overflow, so that the ladle cover and the ladle are completely sealed, the temperature drop of molten steel is reduced, and the final temperature of the converter is favorably reduced.
Drawings
Fig. 1 is a schematic structural diagram of an asymmetric ladle cover.
Fig. 2 is a top view of fig. 1.
In the figure, 1 is a cover body, 2 is a cover edge, 3 is a bag cover, 4 is an inverted Y-shaped anchoring piece, 5 is a heat dissipation prevention protection plate, and 6 is a reinforcing rib.
Detailed Description
Example 1
The present invention will be further explained with reference to the accompanying drawings.
As shown in fig. 1-2, the utility model provides an asymmetric ladle be built by contract, including lid 1, lid 1 periphery is equipped with can cover ladle and wraps the lid along 2, the lid is higher than the bottom surface of lid 1 along 2 bottom surfaces, the lid is equipped with a breach along 2 last ladle package mouth departments that correspond, is equipped with package flap 3 in this breach, package flap 3's bottom surface is higher than the lid along 2 bottom surfaces, lid 1, lid all are equipped with refractory material in along 2 and package flap 3. The ladle cover is divided into three parts, and the cover edge, the ladle opening and the middle are staggered at different heights. The steel slag and the cold steel at the ladle opening are accumulated most, so the ladle opening cover has larger depth; the steel slag and the cold steel at the edge of the ladle are less accumulated than the ladle opening, so the depth of the cover edge is smaller; the size and the depth are beneficial to tight sealing of the ladle cover, and the influence caused by different solidification and caking degrees of the steel slag and the molten steel at the ladle edge and the ladle opening is reduced.
And the cover body is provided with a reinforcing rib 6 for fixing the bag opening cover 3.
An inverted Y-shaped anchoring piece 4 is arranged in the cover edge 2. An inverted Y-shaped anchoring part is arranged in the ladle cover 3. Because of the frequent opening and closing of the ladle cover, Y-shaped refractory anchoring parts are added in the cover edge and the ladle opening cover, so that the Y-shaped refractory anchoring parts are used for resisting static load, thermal stress and vibration force, adjusting the expansion difference between the refractory lining body and metal, reducing cracks and spalling, and reducing the manufacturing cost without adding anchoring parts in the middle of the ladle cover.
The outer wall of the cover edge 2 and the outer wall of the ladle opening cover 3 are both provided with heat dissipation prevention protection plates 5 which extend out of the cover edge by 50cm and are made of high-aluminum refractory fiber plates, so that the high-temperature resistance and thermal shock resistance stability are good, radiant heat loss and smoke overflow can be further reduced, the ladle cover and a ladle are completely sealed, molten steel temperature reduction is reduced, and the final temperature of the converter is favorably reduced.
Claims (5)
