[0002] At present, each section of the tundish of the domestic special-shaped billet continuous casting machine needs to adopt two billet sizing nozzle quick-change mechanisms. The corresponding tundish needs to be used for the special-shaped blank, that is, it needs to be changed to a different tundish for each section of pouring, so that the number of tundishes used is very large, or it is necessary to replace the tundish equipped with mounting plates of different sections. bottom, time-consuming and labor-intensive, and long turnaround time, if the bottom of the bag or the mounting plate is deformed, the steel flow cannot flow into the mold vertically, which directly affects the quality of the billet

Embodiment Construction
[0011] Accompanying drawing takes pouring square billet and four kinds of specification special-shaped billets as example, altogether has a central hole 3 and four groups of eight upper water holes 2 altogether. The upper water hole 2 and the central hole 3 are arranged along the longitudinal axis. The edge of the front of the horizontal plate is provided with snap buttons 4, and beside the snap buttons 4, there are threaded holes 1 along the longitudinal direction; A heat insulation pad is added between the functional connecting plate and the bottom of the tundish; two seat brick positioning walls 5 are arranged on the back of the horizontal plate, and the two seat brick positioning walls 5 are located inside the bottom of the tundish, and the seat brick positioning walls 5 and the longitudinal axis of the horizontal plate Arranged in parallel, a block channel 6 is formed between two block positioning walls 5; the central hole 3 and the water supply hole 2 are both located in...

A multi-functional connecting plate for rapid replacement of nozzles in the continuous casting tundish of special-shaped billets, the purpose of which is to use one connecting plate to pour heterogeneous billets or billets with different specifications and sections; the invention includes a horizontal plate and a positioning wall for seat bricks. A center hole and an upper water hole are arranged along the longitudinal axis. The center hole is a billet hole, and the upper water holes are located on both sides of the center hole. The upper water holes on both sides of the center hole are symmetrically arranged around the center hole; There are snap buttons at the edge, and threaded holes are arranged on the inside of the snap buttons along the longitudinal direction. Two seat brick positioning walls are arranged on the back of the horizontal plate. The two seat brick positioning walls are arranged parallel to the longitudinal axis of the horizontal plate. A block channel is formed between the block positioning walls, and the central hole and the water inlet hole are located in the block channel, and the water inlets with sliding plates suitable for different cross-section shaped billets are installed in the block channel.
Description
technical field [0001] The invention relates to a continuous casting device for special-shaped billets of iron and steel, in particular to a multi-functional connecting plate for quick replacement of nozzles in the continuous casting tundish of special-shaped billets. Background technique [0002] At present, each section of the tundish of the domestic special-shaped billet continuous casting machine needs to adopt two billet sizing nozzle quick-change mechanisms. The corresponding tundish needs to be used for the special-shaped blank, that is, it needs to be changed to a different tundish for each section of pouring, so that the number of tundishes used is very large, or it is necessary to replace the tundish equipped with mounting plates of different sections. The bottom is time-consuming and labor-intensive, and the turnaround time is long. If the bottom of the bag or the mounting plate is deformed, the steel flow cannot flow into the mold vertically, which directly affec...
