Abstract

The invention relates to an aluminum alloy suspending quantitative casting control method. The method is achieved by adopting a control device which comprises a crucible, a main electromagnetic pump, a liquid lifting pipe, a liquid outlet, a laser range finder, a first auxiliary electromagnetic pump and a second auxiliary electromagnetic pump; aluminum liquid sequentially flows through the first auxiliary electromagnetic pump, the second auxiliary electromagnetic pump, the main electromagnetic pump, the liquid lifting pipe and the liquid outlet; the first auxiliary electromagnetic pump is parallel to the second auxiliary electromagnetic pump, and an included angle of 30-60 degrees is formed between the first auxiliary electromagnetic pump and an aluminum liquid conveying pipeline and formed between the second auxiliary electromagnetic pump and the aluminum liquid conveying pipeline; the magnetic induction intensity B of the first auxiliary electromagnetic pump and the magnetic induction intensity B of the second auxiliary electromagnetic pump are same in size and direction; the metal liquid in a magnetic gap of the first auxiliary electromagnetic pump and the metal liquid in a magnetic gap of the second auxiliary electromagnetic pump are same in length; a current of the first auxiliary electromagnetic pump and a current of the second auxiliary electromagnetic pump are same in size and opposite in direction, therefore, the aluminum liquid can be stirred in the direction of being perpendicular to the flowing direction, gas and residues which are mixed in the aluminum liquid can be relatively uniform, and then the quantitative precision is improved.

Description

technical field [0001] The invention relates to an aluminum alloy casting technology, in particular to an aluminum alloy suspension quantitative casting control method. Background technique [0002] Quantitative pouring is a very important process in extrusion casting production. It is difficult to meet the precision requirements of extrusion castings with traditional manual pouring methods, and the production efficiency is low, the production process is unstable, the casting rejection rate is high, and the labor intensity is high. Facing the development trend of high efficiency and high precision in squeeze casting production, it is an urgent problem to be solved in current squeeze casting to improve the automation level and quantitative accuracy of the quantitative pouring process. [0003] The electromagnetic pump uses the current and magnetic field in the conductive fluid to directly act on the electromagnetic driving force (that is, the Loren magnetic force) on the meta...
