Continuous casting production line of oxygen-free aluminum rod by up-draw process

Abstract

The invention relates to a continuous casting production line of an oxygen-free aluminum rod by an up-draw process, mainly comprising a line frequency induction furnace, a high-density aluminum rod crystallizer, a hydraulic traction system and a low-pressure induction type rod-retracting device; the line frequency induction furnace consists of a melting furnace and a heat holding furnace; the high-density aluminum rod crystallizer is arranged in molten aluminum of the heat holding furnace of the line frequency induction furnace; the hydraulic traction system is positioned above of the high-density aluminum rod crystallizer; an aluminum ingot is melted by the line frequency induction furnace and then preserves heat, is inserted into the molten aluminum by the high-density aluminum rod crystallizer and is cooled and crystallized by internal circulating water; and the oxygen-free aluminum rod is pulled upward intermittently by the hydraulic traction system and is coiled by the low-pressure induction type rod-retracting device. The continuous casting production line avoids the serious waste gas and waste water pollution to the atmosphere caused by the prior art, and avoids the problems, such as scaling, scabbing and napping and the like, of the continuously cast and rolled low-oxygen aluminum rod product when a continuous extruder is used, makes up the defects of the prior art andfills the the industry blank of China.

Description

An oxygen-free aluminum rod continuous casting production line with upward pull method technical field The invention relates to an upward-drawing oxygen-free aluminum rod continuous casting production line, in particular to an upward-drawing continuous casting production line for producing pure high-density oxygen-free aluminum rods with clean surfaces and no dirt. Background technique At present, the aluminum rod production line that is widely used by people is mainly made by spraying and burning heavy oil or gas in a cupola reverberatory furnace to melt aluminum ingots, and then rolling them continuously with a rolling mill. liquid contamination. This equipment is called continuous casting and rolling aluminum rod production line. This kind of continuous casting and rolling equipment has been explicitly eliminated in the United States and European developed countries due to serious pollution, and it is also equipment that has been repeatedly proposed or explicitly prohi...

Problems solved by technology

The present invention mainly solves the raw material problem of the continuous extruder. What the continuous extruder originally used was the low-oxygen aluminum rod of continuous casting and rolling. Its first defect is that the oxygen content of the produced product is not high enough. The surface is more likely to be oxidized and discolored if it reaches the international standard; the most important thing is that the surface of the aluminum rod produced by the reverberatory furnace continuous casting and rolling has oil stains on the surface, and it takes a lot of manpower and material resources to clean it and wipe it clean. Dirt makes a large circle of finished products lowered in grade or even scrapped, but now the oxygen-free aluminum rods made by Shangyin are clean oxygen-free aluminum rods that do not contain impurities and dirt, so that they can be used with confidence and reduce The original loss caused by complex processes such as cleaning and peeling has been saved, and a large amount of unnecessary expenses have been saved; the invention has filled the blank in my country's nonferrous metal industry, and also made up for the existing continuous casting and rolling aluminum rod production line.
