Continuous production technique of spray forming ingot

Abstract

The invention discloses a continuous production process of an injection molding ingot. The production process adopts the organic combination of the injection molding technology and the skew rolling mill assembly continuous rolling technology; the injection molding adopts an atomizing nozzle to atomize alloy fluid flowing from a guide tube into tiny molten drops by inert gas such as nitrogen gas, argon gas, and the like, or the mixture thereof, and the molten drops deposit on a dummy sketch to form the ingot; the dummy sketch and the ingot rotate with the skew rolling mill assembly, and move outwards with the rotation of the skew rolling mill assembly; and the ingot is rolled by an inner skew roll of the skew rolling mill to form a round billet and realize the densifying and continuous production. The continuous production process solves the problems that the density of the existing injection molding ingot is low, and the ingot is restricted by the mechanical structure of an ingot depositor and the inner chamber size of an atomization chamber; and the continuous production process can realize production of infinitely long ingots.

Description

technical field [0001] The invention relates to an ingot production process, in particular to a continuous production process for a spray-formed ingot. Background technique [0002] Spray forming technology is a near-net shape, semi-solid metallurgical forming processing technology developed on the basis of powder metallurgy gas atomization powder production. It can not only overcome the defects caused by the traditional smelting and casting process, but also avoid multiple processes such as powder making, pressing, and sintering of powder metallurgy. The academic idea of ​​spray forming was first proposed by Professor Singer of Swansea University in 1968, and its purpose is to obtain the final product or semi-finished product directly from molten metal. Spray forming as an engineering technology began in 1974 when the British Osprey Metals company obtained the patent right. After a lot of research on its process and equipment, Osprey company developed a practical technolo...

Problems solved by technology

[0007] The purpose of the present invention is to provide a continuous production process for spray-formed ingots, which solves the problem of the low density of existing ingots, and realizes the production theory due to the limitation of the mechanical structure and inner cavity size of the ingot depositor. ingot
