Problems solved by technology

As the most effective method to eliminate the above defects, soft reduction technology is also widely used in continuous steel casting technology, and various forces that need to be overcome in the process of soft reduction are factors that need to be carefully considered in the design of modern continuous steel casting equipment. At the same time, because the continuous casting steel billet is formed at high temperature, it is very difficult to detect various forces on-line, which may easily cause safety production accidents

Abstract

A hydraulic control system for soft-reduction analog loading tests comprises a test hydraulic cylinder. The piston cavity and the rod cavity of the test hydraulic cylinder are respectively connected with a test valve device. The test hydraulic cylinder is connected with a loading hydraulic cylinder through a connecting rod. A displacement sensor is mounted on the loading hydraulic cylinder. The piston cavity and rod cavity hydraulic loops of the loading hydraulic cylinder are connected with overflow valves, one-way valves, normally-closed logic valves, normally-open logic valves, proportional pressure reducing valves and a servo valve. The hydraulic control system has the advantages that primary proportional control of pressure is performed on the loading hydraulic cylinder through the proportional pressure reducing valves, precise servo control of pressure is performed on the loading hydraulic cylinder by the aid of the servo valve, and accurate simulation of soft-reduction loading acting force is achieved; the hydraulic control system composed of hydraulic devices is high in automation level, precise in loading force control and safe and reliable.

Description

technical field [0001] The invention relates to the technical field of hydraulic control for continuous steel casting, in particular to a hydraulic control system for a simulated loading test under light reduction. Background technique [0002] In the field of continuous steel casting, with the extensive 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 casting slabs. internal quality. As the most effective method to eliminate the above defects, soft reduction technology is also widely used in continuous steel casting technology, and various forces that need to be overcome in the process of soft reduction are factors that need to be carefully considered in the design of modern continuous steel casting equipment. At the same time, since the continuous casting steel slab is formed at high temperature, ...
