Problems solved by technology

[0004] The existing system has the following problems: (1) It can only simulate the overall cooling characteristics of a single nozzle and the water distribution of a single row of nozzles, but cannot simulate the cooling characteristics of a combination of multiple rows of nozzles; (2) The nozzles are always arranged vertically, and cannot Simulate the position state between the nozzles of some segments of the continuous casting machine and the slab; (3) The multi-row nozzles of modern continuous casting machines are arranged in a staggered manner, and the existing system cannot accurately simulate

Description

technical field [0001] The invention belongs to the technical field of continuous casting, and in particular provides a simulation device for simulating the cooling effect of a secondary cooling nozzle of a continuous casting machine. Background technique [0002] The secondary cooling system of the continuous casting machine has a great influence on the quality of the continuous casting slab. Surface cracks (transverse cracks and longitudinal cracks), internal cracks (triangle cracks and centerline cracks) and center segregation are closely related to the secondary cooling system. The quality of the secondary cooling effect mainly depends on the type and layout of the secondary cooling nozzle, the flow rate and pressure of the secondary cooling water mist cooling, etc. [0003] Yuan Weixia (Yuan Weixia, Liu Chengxin, Zhao Xuesong, Research and Application of Nozzle Spray Cooling Characteristics Test System, Steelmaking, 2004, Vol.20, No.1:36-38, 62) and Wang Fengzhen (Wang ...
