Abstract

The invention discloses a novel solidification system capable of accelerating solidification of metal liquid. The novel solidification system comprises an oil tank, a two-position two-way electromagnetic valve, a hydraulic pump, an overflow valve, a three-position four-way electromagnetic reversing valve and an extrusion oil cylinder, wherein the oil tank is connected with the hydraulic pump and the overflow valve; the two-position two-way electromagnetic valve is arranged between the oil tank and the hydraulic pump; the hydraulic pump is connected with the three-position four-way electromagnetic reversing valve; the three-position four-way electromagnetic reversing valve is connected with the extrusion oil cylinder; a speed adjusting valve is arranged between a pressure reducing valve andthe extrusion oil cylinder; the feeding speed of the extrusion oil cylinder is controlled by the speed adjusting valve. The action time of local pressurization can be adjusted; the effectiveness of the local pressurization can be met as far as possible; the stability of the local extrusion process can be improved.

Description

technical field [0001] The invention relates to a novel solidification system for accelerating the solidification of metal liquid. Background technique [0002] The solidification process of metal liquid is roughly divided into several intervals: liquid phase area, liquid-solid area, solid-liquid area, and solid phase area. Our local extrusion process needs to be done between the liquid phase region and the solid phase region. Due to the limited power source of local pressurization, the speed of hydraulic oil is constant, and the whole pressurization process is completed in a constant short moment. If the starting time is early, it is still in a liquid state, and there is no feeding effect; if the starting time is late, the metal has basically solidified, and extrusion cannot work. Then the pressurization start time in the local pressurization process parameters becomes an extremely important parameter. Often in the normal and stable normal process, the solidification time...
