Detailed Description
According to the utility model, the number of continuous casting furnaces of the phi 390 section is increased and the production efficiency is improved by quickly changing the tundish.
The cross section of the round billet phi 390 is in a minimum specification, and molten steel in the crystallizer contracts and solidifies quickly after the quick-change tundish stops casting, so that a connecting piece is inserted to ensure the connecting effect of a new casting blank and an old casting blank. The special connecting piece for the quick-change tundish, which is designed by the utility model, meets the requirement of firm hot blank connection in the process of connecting the round blank with the phi 390 section quick-change tundish. A middle ladle connecting piece in the quick change of a round billet continuous casting phi 390 section is welded by steel bars and is in an inverted cone shape, the height of the steel bars is 520mm, the diameter of an upper circular ring is 290mm, the diameter of a lower circular ring is 230mm, an upper opening is larger than a lower opening, the middle of the circular ring of the upper circular ring is welded with two crossed reinforcing rods, and the middle of the circular ring is inserted into crystallizer molten steel more easily during quick change. Go up the welding in the middle of ring and the lower ring and have fixed ring, add the welding 10 reinforcing bars in the fixed ring in the connecting rod, on the reinforcing bar of 10 reinforcing bars that add the welding welded welding to the cross, the lower extreme welds to the connecting rod with fixed ring parallel and level, and there are 12 connecting rods, and the bilateral symmetry evenly welds 8 long springs between the connecting rod upper portion. The diameter of the spring is required to be 5mm, the length of the spring is 250mm, Q235-345B is used as a material, the surface is not rusted, and the spring has no elastic force requirement. The molten steel can be rapidly cooled and solidified after being inserted into the crystallizer, and after the new tundish is poured, the molten steel can be rapidly cooled and solidified after entering the crystallizer, so that the cooling effect is ensured, the quick change time is shortened, and the connection between the new molten steel and the old molten steel is ensured to be firm.
In 2019, 9, 3 months and 4 times of quick-change tundish change, single-pouring 60-furnace continuous pouring is smoothly realized. The special connecting piece for the phi 390 section quick-change tundish is a key tool for successful operation of the quick-change tundish, new and old molten steel is cooled and solidified through the connecting piece and firmly connected together, a withdrawal and straightening machine is used for straightening and discharging, the quick-change tundish process is mature and stable, the phi 390 section realizes normalization of the quick-change tundish, and the efficiency of a continuous casting machine is improved.
The above description is only an embodiment of the present invention, but the structural features of the present invention are not limited thereto, and any changes or modifications within the scope of the present invention by those skilled in the art are covered by the present invention.
