Description

Tundish side deslagging system Technical Field The utility model relates to the technical field of continuous casting, in particular to a tundish side deslagging system. Background In the continuous casting production process in the metallurgical industry, a tundish is key equipment for connecting a ladle and a crystallizer, and has the functions of reducing pressure, stabilizing flow, deslagging, homogenizing temperature, splitting flow and storing steel. The traditional tundish deslagging operation mostly adopts an impact area post deslagging method, and the method has the problems of difficult deslagging, short service life, great influence on the quality of casting blanks and the continuous casting production cost and the like. With the development of continuous casting production technology and the improvement of yield, long-life tundish is widely applied, but the traditional deslagging mode can not meet the requirements of modern continuous casting production. The slag-discharging operation mode after the impact area of the continuous casting tundish in the steel plant successfully realizes the service life of continuous casting steel for 24 hours in the tundish, and the number of continuous casting furnaces reaches 40 furnaces. With the increase of continuous casting machine continuous-pulling furnace number, the thickness of the continuous casting tundish slag layer is continuously thickened, the volume of the traditional slag discharge hopper is 3m & lt 3 & gt, the requirement can be met under the condition that the tundish continuous-casting furnace number is 40, the tundish continuous-casting furnace number is increased to be more than 80, the volume of the traditional slag discharge hopper can not meet 80, the molten steel liquid level is too high, and steel slag floating on the surface is sucked into a crystallizer, so that the cast steel quality is also influenced. Disclosure of utility model The utility model aims to provide a tundish side slag discharging system, which aims to solve the problems that as the continuous casting machine continuous-drawing furnace number increases, the thickness of a continuous casting tundish slag layer is continuously thickened, the volume of a traditional slag discharging hopper is 3m & lt 3 & gt, the requirement can be met under the condition that the tundish continuous-casting furnace number is 40, the tundish continuous-casting furnace number is increased to more than 80, the volume of the traditional slag discharging hopper cannot meet 80, the liquid level of molten steel is too high, steel slag floating on the surface is sucked into a crystallizer, and the cast steel quality is influenced. The foundation scheme of the utility model is that the tundish side slag discharging system comprises a tundish body and a supporting table, wherein one side of the tundish body is communicated with a conical slag disk, a slag discharging chute is communicated with the conical slag disk, the slag discharging chute is positioned on one side of the conical slag disk, the supporting table is attached to the tundish body, a slag overflow hopper is arranged on the supporting table, the slag overflow hopper is positioned below the slag discharging chute, and one side of the slag overflow hopper is communicated with the slag overflow hopper chute. The utility model has the principle and beneficial effects that the slag discharge operation of the impact area side is changed from the slag discharge of the original tundish, so that the replacement of the slag overflow hopper is simple and convenient, the slag discharge position is lifted by using the travelling crane after the tundish is fully discharged and the ladle is transferred to the horizontal position, the problem that the steel slag in the tundish cannot be discharged due to the limit of the volume of the slag overflow hopper is effectively solved, and the influence on other casting processes is possibly reduced, thereby improving the overall production efficiency and the product quality. And in the second scheme, as the optimization of the basic scheme, one side of the supporting table is fixedly connected with a diversion trench, and the diversion trench is positioned below the slag overflow hopper spout. Slag overflowed from the chute mouth of the slag overflow hopper flows into the material receiving dump truck from the diversion trench. And a third scheme is the optimization of the basic scheme, and a plurality of lifting lugs are arranged on the slag overflow hopper. When the slag overflow hopper needs to be replaced, the lifting lug is hung by the lifting device, and then the slag overflow hopper is lifted. And a fourth scheme is a preferable scheme based on the above, and the slag overflow bucket supporting table is made of steel plates. The slag overflow bucket supporting table is formed by welding steel plates with the thickness of 25mm, and the design is sufficient in operation convenience and safety performa
