Abstract
The utility model discloses a kind of continuous casting production slag weir of improvement, comprise slag weir body, in the end face both sides of slag weir body, a groove is set respectively, groove floor is arranged hanger, the front and rear surfaces of slag weir body is inclined-plane, the vertical section of slag weir body is isosceles trapezoid, and in slag weir body, horizontal interval arranges three pieces of magnesia carbon bricks from top to bottom.The utility model can effectively make the inclusion floating in tundish in molten steel and be absorbed by tundish covering flux, suspension ring can be avoided to be clashed in transit simultaneously, increases the ability that slag weir opposing molten steel corrodes.
Description
Technical field
The utility model relates to a kind of continuous casting production slag weir of improvement.
Background technology
How tundish, as the container of the liquid molten steel of last splendid attire of steel making working procedure, play its metallurgical function to greatest extent, is the problem that continuous casting worker is concerned about always.In tundish, arrange slag weir is one of the most frequently used means, and its major function one is the slag of gear toward large bag, and two is adjustment Tundish Flow Fields.Originally the weight of the slag weir of use is at about 100 kilograms, therefore suspension ring structure is adopted, intermediate package timing uses driving crane lifting, because suspension ring are exposed, mainly there is following defect: be easily subject to shock at transportation suspension ring and cause suspension ring to be out of shape and cannot handling, time serious, damage is caused to the material near suspension ring, slag weir is scrapped.In addition, also there are the following problems for traditional pouring basket slag stop weir, dam, and 1, average steel Flow Velocity in tundish is still very fast, cannot increase the time of staying of molten steel in tundish preferably.2, molten steel gear weir and gear dam surface velocity very fast, easily cause the melting loss of resistance to material on gear weir and gear dam, reduce tundish service life.3, cannot play the effect on gear weir after slag weir, dam melting loss, its resistance to material fuses in steel and increases being mingled with in molten steel, causes adverse effect to continuous casting billet quality.
Summary of the invention
The purpose of this utility model is the continuous casting production slag weir providing a kind of improvement, can effectively make the inclusion floating in tundish in molten steel and be absorbed by tundish covering flux, suspension ring can be avoided to be clashed in transit simultaneously, increase the ability that slag weir opposing molten steel corrodes.
The purpose of this utility model realizes like this, a kind of continuous casting production slag weir of improvement, comprise slag weir body, in the end face both sides of slag weir body, a groove is set respectively, groove floor is arranged hanger, the front and rear surfaces of slag weir body is inclined-plane, and the vertical section of slag weir body is isosceles trapezoid, and in slag weir body, horizontal interval arranges three pieces of magnesia carbon bricks from top to bottom.
The utility model improves suspension ring structure, changes suspension ring position into up concave type, avoids suspension ring to be clashed in transit.Pre-buried 3 pieces of magnesia carbon bricks in slag weir, be used for increasing the ability that slag weir resists molten steel erosion, improve service life of refractory material, pushing off the slag effect improves, and can improve continuous casting billet quality.Its structural strength is high, can effectively make the inclusion floating in tundish in molten steel and be absorbed by tundish covering flux, suspension ring can be avoided to be clashed in transit simultaneously, increases the ability that slag weir opposing molten steel corrodes.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is main TV structure schematic diagram of the present utility model;
Fig. 2 is side-looking structural representation of the present utility model.
Detailed description of the invention
A kind of continuous casting production slag weir of improvement, as shown in Figure 1 and Figure 2, comprise slag weir body 2, in the end face both sides of slag weir body 2, a groove is set respectively, groove floor is arranged hanger 1, the front and rear surfaces of slag weir body 2 is inclined-plane, and the vertical section of slag weir body 2 is isosceles trapezoid, and in slag weir body 2, horizontal interval arranges three pieces of magnesia carbon bricks 3 from top to bottom.
