Description
Technical Field
The utility model belongs to the technical field of metallurgical function refractory material, concretely relates to combination formula stopper stick is used in continuous casting.
Background
The stopper is one of the functional refractory materials for continuous casting, and is called three main parts for continuous casting together with the submerged entry nozzle and the long nozzle. The stopper rod is used for the tundish and is matched with the submerged nozzle bowl part, and the flow of molten steel entering the crystallizer is adjusted by adjusting the positions of the stopper rod head and the nozzle bowl part, so that the function of adjusting the flow of the molten steel is achieved. Along with the development of continuous casting technology, the improvement of continuous casting level puts higher requirements on the use of a stopper rod for continuous casting, and the stopper rod body is made of Al2O3The material C, the stopper rod head is used as a key part for determining the flow control function and the service life of the stopper rod, different materials and structures are selected according to the production process and different operating conditions of a steel mill, and the material can be divided into Al2O3-C, MgO-C, MA-C, and argon blowing, argon non-blowing, and composite structures.
At present, the stopper rod is produced by adopting an integral functional composite structure and an integral forming process. High production cost and long production period, and can not effectively meet the requirement of adjusting the production process of a steel mill in time.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a combination formula stopper rod for continuous casting can change the stick head of different materials and structure according to the needs of steel mill production technology, improves the adaptability of stopper rod, satisfies the high-efficient production of continuous casting.
The utility model adopts the following technical scheme for accomplishing the above purpose:
a combined stopper rod for continuous casting comprises a rod body, a rod head and a connecting piece; the lower part of the rod body and the upper part of the rod head are both provided with structures with internal threads; the connecting piece is of a structure with external threads on the outer wall surface, and a dispersion inner core for forming an argon flow channel is arranged in the connecting piece; the external thread of the connecting piece is matched with the internal thread at the lower part of the rod body and the upper part of the rod head; the rod body and the rod head are connected into a whole through the connecting piece to form the combined stopper with a detachable structure.
The utility model provides a pair of combination formula stopper rod for continuous casting adopts above-mentioned technical scheme, can realize selecting the stick head and the excellent body cooperation of different materials and structure to constitute the stopper rod according to the needs of steel mill production technology adjustment, has effectively improved the adaptability and the production efficiency of stopper rod.
