Abstract

The invention relates to a high-efficiency crystallizer for a continuous casting machine, which comprises a crystallizer tube wall and fins, the fins are evenly distributed outside the crystallizer tube wall, the fins and the crystallizer tube wall form an upper cavity and a lower cavity, and the upper part The cavity and the lower cavity are respectively located at the upper and lower ends of the crystallizer tube wall. A high-efficiency crystallizer for a continuous casting machine of the present invention can greatly reduce the tendency of the crystallizer to be squared off, rhomboid and bulging, thereby reducing the amount of grinding of the slab and improving the metal yield of the slab. At the same time, due to the increased capacity of the cooling system, it is easier to achieve high-efficiency continuous casting under the premise of ensuring quality; at the same time, a water-filled cavity is designed at the upper and lower ends of the crystallizer, so that the cooling water can be uniform The water flow is distributed to ensure uniform cooling and heat dissipation in the circumferential direction, so that the shell thickness of the billet grows uniformly during the solidification process in the mold.

Description

technical field [0001] The invention relates to the technical field of crystallizers, in particular to a high-efficiency crystallizer for continuous casting machines. Background technique [0002] At present, the crystallizer copper tube (plate) devices used in square, rectangular, round and slab continuous casting machines are all in the form of relatively smooth inside and outside. In the continuous casting process, a large amount of cooling water is required to meet the process effect , and the temperature requirements for the inlet and outlet water of the crystallizer cooling water are relatively strict, which has a great impact on the production cost of the enterprise; at the same time, the existing crystallizer copper tube (plate) after a period of use , due to the relatively high water quality requirements for cooling water, once the water quality cannot meet or can only barely meet the production requirements, the service life of the copper tube (plate) of the mold w...
