Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
As shown in figure 1, the utility model discloses a molten steel current stabilizer, which comprises a prefabricated block body 1. The middle part of the upper surface of the prefabricated block body 1 is provided with a groove 2 downwards. The groove 2 is formed to have a groove bottom surface and four side wall surfaces. The bottoms of the four side wall surfaces are arranged obliquely towards the direction of convergence.
As shown in fig. 2 and 3, the prefabricated block body 1 is provided with a flow guide channel 3, and the flow guide channel 3 is communicated with the groove 2 and the lower surface of the prefabricated block body 1. Molten steel poured into the groove 2 can be left from the lower surface of the prefabricated block body 1 along the diversion channel 3, so that the position where the molten steel is left can be conveniently controlled.
As shown in fig. 1 and 2, the prefabricated block body 1 is further provided with a spillway 4. The overflow 4 is arranged above the diversion channel 3. When the molten steel poured into the groove 2 is too much and exceeds the maximum flow rate which can be borne by the diversion channel 3, the molten steel is moved out of the overflow port 4, and the molten steel is prevented from overflowing from the position around the groove 2.
The prefabricated block 1 is also provided with a flow channel 5. The flow channel 5 is in an inverted isosceles trapezoid shape. The flow passage 5 communicates the overflow 4 with the lower surface of the prefabricated block 1, and the top of the flow passage 5 communicates the entire overflow 4. The molten steel overflowing from the weirs 4 moves along the runner 5 and the runner 5 is gradually contracted from the top to the bottom, so that the molten steel flowing down from the runner 5 can be collected and left at one place, and the position of the molten steel when it falls down can be controlled.
