Abstract
The utility model belongs to special equipment, wherein, the special equipment is arranged in a middle ladle, and the special equipment is used for controlling the flow, the mixture, and the stay of melting steel and promoting the elimination of impurities in the process of the continuous casting of a metallurgy industry steel plant. The utility model is composed of the upper part of a turbulence controller for the continuous casting middle ladle and a low control component at the lower part, wherein, the turbulence controller is made of refractory materials. The flow control component at the upper part forms an inverted dish shape. The middle part is provided with a small upper part and big lower part stair-shaped elliptical hole. The flow control component at the lower part forms a bowl shape. One side of the lower part is provided with a slope with a 10 DEG to 20DEG angle. The elliptical hole at the inner part is concentric with the hole of the flow control component at the upper part. The utility model is arranged at the front lower part of a long water mouth, and the utility model corresponds to a melting steel casting mouth. The utility model has an anti-splatter function, turbulent fluctuation external leakage caused by the impact of the melting steel of the long water mouth is restricted, and the form of a piston is promoted. Thus, the even melting steel is satisfies and a stagnation region of the melting steel is reduced so that the volume of the stagnation region is less than 13 percents, and then, the quality of casting blanks is enhanced. The utility model has the advantages of reasonable design and simple processing.
Description
Technical field the utility model belongs to be arranged in the metallurgy industry steel plant continuous casting process and is used to control molten steel flow, mixing and stop in the tundish, promotes the special equipment that field trash is got rid of, particularly a kind of continuous casting tundish turbulence inhibitor.
Background technology is present, domestic metallurgy industry steel plant continuous casting injects the process of tundish at molten steel, molten steel flow is rapid and not steady in the tundish, cinder inclusion is involved in molten steel, molten steel secondary oxidation in the middle of can causing, it flows and is made up of three parts, that is: piston flow, complete mixing flow and stagnant area (dead band), wherein piston flow and complete mixing flow are referred to as the region of activation.MOLTEN STEEL FLOW in tundish is the single-stage mode, does not have obviously full confounding and piston region feature during incoming flow molten steel flow further downstream.Turbulent Kinetic branch shows that molten steel is not subjected to any constraint from the upstream flow further downstream, and there is bigger stagnant area in MOLTEN STEEL FLOW in the tundish.Account for about 40% of whole tundish volume by detecting the molten steel stagnant area, the molten steel mixed effect is relatively poor in the tundish, is unfavorable for stablize the molten steel supply, satisfies the realization that molten steel composition and temperature evenly, effectively promote function such as field trash eliminating.Chinese patent 98236188.2 is disclosed by retrieval is the anti-turbulent flow partition wall of a kind of continuous casting tundish, the trapezoidal partition wall that adopts refractory material to make, it is characterized in that partition wall is made of the plate that two last bases have the arc radius, two plate upper flanges are relative, respectively there is a discharge orifice at the center of going to the bottom, partition wall and big bag long nozzle center line symmetry, partition wall can directly be built by laying bricks or stones or once-forming is wrapping at the end, and partition wall two bottom side lengths coincide with the interior corresponding cross dimensions of tundish.This partition wall can make tundish molten steel flow speed and kinetic energy reduce greatly.
The summary of the invention the purpose of this utility model is for solving the deficiency of above-mentioned existence, molten steel flow state in the control tundish, reduce the molten steel stagnant area, effectively remove non-metallic inclusion, reach purify hot metal, improve slab quality, a kind of continuous casting tundish turbulence inhibitor is provided.
The utility model continuous casting tundish turbulence inhibitor content Description:
The utility model continuous casting tundish turbulence inhibitor, it is characterized in that: form by continuous casting tundish turbulence inhibitor top and bottom control fluid element that refractory material is made, top control fluid element is shaped as an inverted dish, and the centre has up-small and down-big stair-stepping slotted eye; Bottom control fluid element is shaped as bowl-type, and bottom one side has the inclined-plane at 10～20 ° of angles, and inner slotted eye is concentric with the hole of top control fluid element.
Continuous casting tundish turbulence inhibitor be arranged on long nozzle in the tundish under, corresponding with casting molten steel mouth.
The utility model continuous casting tundish turbulence inhibitor, under long nozzle, be provided with, has the splashproof function, restriction long nozzle molten steel impacts the formation that the turbulent flow pulsation that causes leaks and promotes piston, to satisfy even molten steel and to reduce the molten steel stagnant area, the volume that makes the stagnant area can effectively be removed the non-metallic inclusion purify hot metal, improve slab quality less than 13%.The utlity model has reasonable in design, processing is simple, the characteristics of remarkable in economical benefits.
Description of drawings Fig. 1 is a continuous casting tundish turbulence inhibitor structural representation
Among Fig. 1: 1 is that continuous casting tundish turbulence inhibitor top control fluid element, 2 is continuous casting tundish turbulence inhibitor bottom control fluid element.
Specific embodiment the utility model continuous casting tundish turbulence inhibitor is to realize like this, see Fig. 1, specify below in conjunction with accompanying drawing, form by continuous casting tundish turbulence inhibitor top control fluid element 1 and bottom control fluid element 2 that refractory material is made, top control fluid element 1 is shaped as an inverted dish, and the centre has up-small and down-big stair-stepping slotted eye; Bottom control fluid element 2 is shaped as bowl-type, and bottom one side has the inclined-plane at 10～20 ° of angles, is used for fixing the position of controller, and inner slotted eye is concentric with the hole of top control fluid element 1.Continuous casting tundish turbulence inhibitor be arranged on long nozzle in the tundish under, corresponding with casting molten steel mouth, has the splashproof function, restriction long nozzle molten steel impacts the formation that the turbulent flow pulsation that causes leaks and promotes piston, to satisfy even molten steel and to reduce the molten steel stagnant area, the volume that makes the stagnant area can effectively be removed the non-metallic inclusion purify hot metal, improve slab quality less than 13%.
