A horizontal continuous casting equipment for aluminum alloy ingot

Abstract

The invention discloses a horizontal continuous casting equipment for aluminum alloy ingots, mainly by setting an oil supply part between the guide cylinder and the crystallizer, so as to achieve continuous supply of lubricating oil between the crystallizer and the ingot without using graphite rings Effect. The main technical proposal is: a horizontal continuous casting equipment for aluminum alloy ingot, including: tundish, guide cylinder, crystallizer and casting equipment; Connected with the guide cylinder, the casting equipment is set outside the crystallizer; the tundish is used to store the molten aluminum, and the guide cylinder is used to guide the molten aluminum flowing out of the tundish into the mold, and the mold is used to solidify the molten aluminum into an ingot, casting The equipment is used to pull and cut the ingot; wherein, the mold is provided with an oil supply part, and the oil supply part is used to provide lubricating oil to the inner wall of the mold from between the guide cylinder and the mold. The present invention is mainly used for casting.

Description

technical field [0001] The invention relates to the field of casting technology, in particular to horizontal continuous casting equipment for aluminum alloy ingots. Background technique [0002] At present, aluminum alloy ingots are mainly produced by vertical semi-continuous casting technology. Compared with vertical casting, horizontal continuous casting technology has the advantages of less investment, high yield, high safety factor, and real continuous casting. It has a good application prospect in the production of aluminum alloy ingots. However, some problems in horizontal continuous casting have affected the application and popularization of this technology. There are two obvious problems. One is that due to the effect of gravity, the ingot is cooled unevenly on the cross section, which leads to differences in the structure and properties of the ingot. This is manifested in the production process of large-scale ingots. Especially obvious; secondly, the production du...

Problems solved by technology

This method can achieve continuous lubrication in the casting process, but requires porous gas-permeable graphite as the main material of the crystallizer, which is costly and prone to oxidation after long-term use, resulting in poor gas permeability

Patent US7143809 proposes a horizontal continuous casting device, which introduces gas and lubricating oil between the crystallizer and the slab for the purpose of lubrication, but this device also needs porous gas-permeable graphite as a permeation channel for oil and gas, and Porous and breathable graphite can only be produced by a few foreign manufacturers, resulting in high cost and no domestic materials to replace it
