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

Abstract

The invention discloses a light alloy casting and rolling experimental device, belongs to the field of light alloy casting, and aims to solve the problem that an integrated forming device capable of realizing double-roller casting and rolling is lacked at present. According to the device, alloy heating and casting are combined into a whole, an alloy is subjected to heat preservation after being heated, a smelting furnace is directly pushed to the position above rollers, a rotating poking wheel of the smelting furnace is rotated, a smelting furnace cover is automatically opened, and the alloy melt is directly poured into a roller gap between the two rollers. The alloy melt is always in a heat preservation state before pouring, so that the heat loss of the alloy melt is reduced, the oxidation degree of the alloy is also reduced, and meanwhile, the safety of the whole operation process is relatively high. Cooling channels are arranged on the outer sides of the rollers, so that the roller adjusting difficulty is matched, and the roller machining difficulty is reduced; according to the device, the axes of the two rollers can be kept parallel and synchronously adjusted all the time, synchronous and opposite rotation of the two rollers is achieved through improvement of a transmission route, and the machining effect is guaranteed.

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...
