Background
The continuous casting tundish is a refractory container used in short-flow steelmaking, receives molten steel poured from a ladle, and then distributes the molten steel into a crystallizer through a tundish nozzle. The tundish mainly has five functions in steelmaking, namely: the diversion effect, the continuous casting effect, the decompression effect, the protection effect and the impurity removal effect.
In actual production, the number of tundish nozzles is required to be matched with the requirements of the continuous casting machine according to the machine and flow number design conditions of the continuous casting machine. The position of the mold of the continuous casting machine is fixed, and the tundish or the nozzle position needs to be adjusted in order to ensure that the nozzle is positioned at the center of the mold during casting. However, for multi-machine and multi-stream continuous casting machines, the relative position between each stream needs to be adjusted, so that the positioning work of the water outlet seat brick is finished when the tundish is built, the position deviation is avoided, and the bias current or the lack-stream casting when the continuous casting machine is started is caused, so that the production efficiency is influenced.
In the traditional tundish repairing process, the center position of the brick cup is generally determined by using a box ruler in the positioning of the water gap brick cup, the space in the tundish is narrow, the operation process is complex, and the position deviation is large. Especially for the continuous casting machine tundish with the non-in-line arrangement of the crystallizer, the relative position of the nozzle pocket bricks is more difficult to determine, which causes frequent accidents of the casting machine in-flow casting.

The utility model aims to provide a multi-stream continuous casting tundish nozzle pocket block positioning tool which can assist in installing and positioning a tundish nozzle pocket block when a multi-stream continuous casting machine tundish is built, ensure that the position of each stream meets the requirement, ensure that the whole stream is normally cast, and solve the problems in the background art.
The technical scheme of the utility model is as follows:
The utility model provides a package mouth of a river brick cup positioning tool in middle of multi-stream continuous casting, contains spacing pipe of brick cup, the locating plate, handheld handle, cladding location ring and middle package bottom cladding, be equipped with handheld handle on the spacing pipe of brick cup, be equipped with four locating plates of evenly arranging on the spacing pipe circumferencial direction of brick cup, the length of four locating plates cooperatees with the internal diameter of cladding location ring, cladding location ring welding is on middle package bottom cladding, cladding location ring and middle package bottom cladding support on four locating plates of evenly arranging on the spacing pipe circumferencial direction of brick cup.
The brick cup limiting pipe is a metal round pipe, and the diameter of the metal round pipe is matched with the inner diameter of the nozzle brick cup.
Four locating plates uniformly arranged in the circumferential direction of the brick cup spacing pipe are on the same horizontal plane, and the included angle between two adjacent locating plates is 90 degrees.
The cladding locating ring is welded at the position of each flow opening of the cladding at the bottom of the tundish.
The circle centers of the brick cup limiting pipe and the cladding positioning circular ring are all on the central line of each flow of the tundish.
The beneficial effects of the utility model are as follows: the utility model can assist the installation and positioning of the tundish nozzle pocket bricks when the tundish of the multi-stream continuous casting machine is built, simplify the installation steps of the tundish nozzle pocket bricks, ensure that the position of the nozzle of each stream of the tundish meets the requirements, ensure the normal casting of the whole stream and improve the production efficiency of steel smelting.
