Description

technical field [0001] The invention belongs to the technical field of a hydraulic control test system, and in particular relates to a hydraulic position and pressure closed-loop control dynamic static simulation test system and method. Background technique [0002] In the field of steelmaking, with the wide demand for slabs in the market, the specifications of the cast slabs are getting thicker and thicker, and the resulting looseness and segregation of the slab center are becoming more and more serious, which greatly affects the quality of the slabs. internal quality. [0003] As the most effective method to eliminate the above defects, soft reduction technology is also widely used in continuous casting technology. In the process of soft reduction, it is necessary to accurately control the position or pressure of the hydraulic cylinder to realize the function of soft reduction on the slab, but Since the continuous casting slab is formed at high temperature, it is necessar...
