Abstract

The invention relates to the technical field of continuous casting processes, in particular to a method for quickly replacing tundish of peritectic steel steel grade. The method for quickly replacingthe tundish of the peritectic steel steel grade comprises the following steps that in a process of pouring molten steel into a mold in the first tundish, the weight of the first molten steel in the first tundish is monitored; the casting speed is reduced according to the weight of the first molten steel and a preset speed reducing rule; the second tundish is centered; a cold water distribution isinjected into the mold when the weight of the first molten steel is reduced to a first preset weight and the casting speed is reduced to a first preset speed; a blind plate is driven into a first tundish car, a connecting part is inserted into the mold, so that the first tundish stops pouring; the first tundish car is driven to a baking position from a pouring position, and a second tundish car isdriven to the pouring position, so that the first tundish is replaced with the second tundish, the tundish quick change efficiency is improved through the second tundish centering and the casting speed controlling process, the cold water distribution is injected into the mold according to the preset target value, a blank shell shrinkage is effectively controlled, and leakage steel accidents are avoided.

Description

technical field [0001] The invention relates to the technical field of continuous casting technology, in particular to a method for quickly changing tundishes of peritectic steel grades. Background technique [0002] With the development of iron and steel enterprises and the improvement of the overall industrial level, the production capacity of iron and steel continues to expand, and the requirements for production efficiency are getting higher and higher. Improving the production efficiency of continuous casting and realizing continuous casting of various steel types for a long time is an urgent need to be solved. a problem. At present, the submerged nozzle quick change process, ladle quick change process and related equipment have been developed. At the same time, the service life of the continuous casting tundish is also very important. Currently, the tundish quick change technology can reduce the number of shutdowns of the casting machine and effectively reduce the tund...
