Molten aluminum chute with balanced temperature gradient

Abstract

The invention provides a molten aluminum chute with balanced temperature gradient, and relates to the field of cast-rolled aluminum. The problems that cooling pipes are not uniformly distributed enough, cooling is one-sided and the efficiency is low, cooling gas in the cooling pipes is locally heated in the cooling process, and flowing and mixing of the gas cannot be realized in the cooling process, and the chute can be disassembled and taken out only by completely disassembling a plurality of fixing bolts during disassembly, maintenance or replacement are solved; the molten aluminum chute with balanced temperature gradient comprises a chute main body, and a cooling structure is mounted on the chute main body. Due to the fact that the initial state of an elastic gas cylinder is an extension state, and the initial state of the gas cylinder is a compression state, and when the elastic gas cylinder is extruded, the cooling gas in a connecting base and the cooling pipes is in a motion mixing state, so that the cooling efficiency can be improved; due to the fact that the length of a poke rod is larger than the distance between a rocker arm and a stress plate, when the rocker arm is continuously rotated, the elastic gas cylinder is in a continuous extrusion state at the moment, and gas exchange in the cooling pipes is achieved.

Description

technical field [0001] The invention belongs to the technical field of casting and rolling aluminum, and more particularly relates to an aluminum liquid chute with balanced temperature gradient. Background technique [0002] In the aluminum melt production industry, the chute is an essential basic equipment for production, which is used for the transfer of molten aluminum between equipment and the transfer and supply of molten aluminum between technological processes such as degassing, filtration, and casting. The current chute is generally made of RSK-Ⅱ brown corundum castable castable in sections, the shape is wide at the top and narrow at the bottom, and the inner wall is a regular semi-ellipse shape. [0003] There are still the following deficiencies in the current use of aluminum liquid chute: [0004] One is that when the existing device is cooled and formed, the distribution of the cooling pipes is not uniform and the cooling efficiency is low, and the cooling gas i...

Problems solved by technology

[0006] In order to solve the above technical problems, the present invention provides a liquid aluminum chute with a balanced temperature gradient to solve the problem that the cooling pipes in the existing device are not evenly distributed and the cooling efficiency is low when the temperature is lowered for forming, and the cooling in the cooling pipes during the cooling process. There is local heating of the gas, the flow and mixing of the gas cannot be realized during the cooling process, and the cooling efficiency is low; moreover, when the existing device is disassembled for maintenance or replacement, it is necessary to dismantle all the fixing bolts to realize the disassembly of the chute Take out, troublesome disassembly
