Abstract

The invention relates to a continuous casting porous stopper rod which comprises a rod body and a rod head connected with the rod body, and further comprises a blowing channel arranged in the rod body, blowing branches used for conveying shielding gas, arranged on the rod head, connected with the blowing channel and used for distributing the shielding gas conveyed by the blowing channel to all directions; the number of the air blowing branches is at least two, and the air outlet direction of the at least two air blowing branches has components in the circumferential direction of the stopper rod. Due to the fact that the air outlet directions of the multiple air blowing branches have components in the circumferential direction of the stopper rod, the multiple air blowing branches face the same circumferential direction, bubbles rotating around the rod head are formed around the rod head, surrounding molten steel is driven to rotate, and attachments in a water gap can be better cleaned.

Description

technical field [0001] The invention relates to the technical field of continuous casting of molten steel, in particular to a continuous casting porous stopper. Background technique [0002] In the process of continuous casting of molten steel, continuous casting of multiple furnaces is carried out, and the tundish uses stopper rods to control the flow. The stopper rod includes the rod body and the rod head. With the prolongation of the casting time, impurities with high melting points will be formed in the molten steel during the pouring process. The precision of the flow control of the club head. [0003] In the prior art, an argon blowing channel is arranged in the stopper rod, and impurities are washed away by argon. Further, the argon blowing channel on the rod head is divided into multiple branches, and multiple argon blowing holes are set near the position where the rod head contacts the bowl mouth, which can better reduce the impurity products in the contact part b...
