Description
Technical Field
The invention belongs to the field of light alloy casting, and particularly relates to a light alloy casting and rolling experimental device.
Background
The twin-roll casting and rolling integrated forming technique is a relatively advanced technique in the field of metallurgy and material science, and is characterized by that two rolls with opposite rotation directions are used as crystallizer of metal material, and the metal melt is poured into the zone formed from gap positions of two rolls, so that the alloy melt can be directly cast into the thin strip with required size. The twin-roll casting and rolling integrated forming is an organic combination of metal solidification crystallization and rolling deformation processes, namely, the molten metal is subjected to pressure processing and plastic deformation of two rolls while being subjected to crystallization solidification, so that the whole process from liquid metal to solid thin strip forming is completed in a relatively short time.
The twin-roll liquid casting eliminates the traditional hot rolling process, namely, the liquid metal directly casts and rolls the thin plate without intermediate cooling and reheating processes, thereby greatly shortening the production flow. However, the process parameters such as pouring temperature, casting speed, roll gap size, etc. have a great influence on the casting and rolling integrated forming process, so that the control of the twin-roll casting and rolling integrated forming process is very complicated. The smelting furnace and the casting and rolling equipment in the traditional casting and rolling experimental device are separately arranged, so that the alloy melt has the problems of heat loss and oxidation in the transportation process, and certain dangers exist due to improper operation. In addition, the cooling speed has a great influence on the alloy performance, and a cooling water channel needs to be arranged in the roller in the traditional casting and rolling process, so that the processing difficulty of the roller is increased, and a cooling water device also needs to be equipped. In addition, the roll gap needs to be adjusted according to actual conditions, and the traditional casting and rolling experimental device generally only adjusts two ends of one roll to reduce or enlarge the roll gap, so that the roll gap is difficult to be ensured to be uniform and not eccentric, and a great amount of time is usually spent on keeping the axes of the two rolls parallel.
