A light alloy casting and rolling experimental device

Abstract

The invention discloses a light alloy casting and rolling experimental device, which belongs to the field of light alloy casting. Aiming at the problem of the lack of an existing twin-roll casting and rolling integrated forming device, the invention combines alloy heating and casting into a Integral, the alloy is heated and kept warm, the melting furnace is directly pushed above the rolls, the rotary dial of the melting furnace is turned, the melting furnace cover is automatically opened, and the alloy melt is directly poured into the gap between the two rolls. The alloy melt is kept in a heat preservation state before pouring, thereby reducing the heat loss of the alloy melt, and also reducing the degree of alloy oxidation, and at the same time, the safety of the entire operation process is high. Setting the cooling channel on the outer side of the roll coordinates the difficulty of roll adjustment and reduces the processing difficulty of the roll. The invention can always keep the axes of the two rolls parallel and synchronously adjusted. Through the improvement of the transmission route, the synchronous alignment of the two rolls is realized. To rotate to ensure the effect of processing.

Description

technical field [0001] The invention belongs to the field of light alloy casting, in particular to a light alloy casting and rolling experimental device. Background technique [0002] Twin-roll casting and rolling integrated forming is a cutting-edge technology in the field of metallurgy and material science. The twin-roll casting and rolling integrated forming technology uses two rolls with opposite rotation directions as the crystallization of metal materials. The metal melt is poured into the area formed by the gap between the two rolls, so that the alloy melt can be directly cast into a thin strip of the required size. The integrated forming of twin-roll casting and rolling will be an organic combination of metal solidification crystallization and rolling deformation process, that is, the molten metal must bear the pressure processing and plastic deformation of the two rolls while crystallizing and solidifying, so in comparison Complete the entire process from liquid me...

AI Technical Summary

Problems solved by technology

However, since various process parameters such as pouring temperature, casting and rolling speed, and roll gap size have a great influence on the integrated casting and rolling forming process, the integrated forming control of twin-roll casting and rolling is very complicated.

In the traditional casting and rolling experimental device, the melting furnace and the casting and rolling equipment are arranged separately. There are heat loss and oxidation problems during the transportation of the alloy melt, and there are certain dangers due to improper operation.

In addition, the cooling rate has a great influence on the properties of the alloy. In the traditional casting and rolling process, cooling water channels need to be installed in the roll, which increases the processing difficulty of the roll. At the same time, a cooling water device is also required.

In addition, the distance between the rolls needs to be adjusted according to the actual situation. Traditional casting and rolling experimental devices generally only adjust the two ends of one of the rolls to reduce or increase the gap between the rolls. It is difficult to ensure that the gap is uniform and not eccentric. time to keep the axes of the two rolls parallel
