Two-way foamed aluminum ingot casting continuous production line

Abstract

The invention provides a continuous production line for casting bidirectional foamed aluminum and aluminum ingots. A stirring assembly is arranged at the discharge end of the hot melting furnace, and parallel first casting lines and second casting lines are arranged on both sides of the stirring assembly. The aluminum liquid of the foaming agent is fully stirred and foamed. After the stirring is completed, the stirring assembly injects the aluminum liquid into the first casting aluminum mold of the first casting line, and then the stirring assembly automatically switches the direction of the aluminum liquid outflow. The second casting aluminum mold is injected with molten aluminum, and then the stirring assembly switches direction again to inject molten aluminum into the first casting aluminum mold of the first casting line. This alternate operation solves the technical problem of two-way continuous production of foamed aluminum and realizes two Continuous casting of a foamed aluminum ingot production line.

Description

technical field [0001] The invention relates to the technical field of foamed aluminum-aluminum ingot casting, in particular to a continuous production line for bidirectional foamed aluminum-aluminum ingot casting. Background technique [0002] Due to the low density, high rigidity, corrosion resistance and good formability of aluminum, the application of aluminum continues to increase. This trend is particularly evident in the automotive industry, household appliances and construction industries, where complex shapes and high strength are required. There is a huge demand for aluminum materials. However, the production equipment and systems of foamed aluminum in the prior art have the defects of uncontrollable foaming, discontinuous production, low production capacity, high energy consumption, high production cost and cumbersome process. The pass rate of the product is low, and there are many problems such as low safety factor in production. [0003] In the Chinese patent w...

[0002] Due to the low density, high rigidity, corrosion resistance and good formability of aluminum, the application of aluminum continues to increase. This trend is particularly evident in the automotive industry, household appliances and construction industries, where complex shapes and high strength are required. There is a huge demand for aluminum materials. However, the production equipment and systems of foamed aluminum in the prior art have the defects of uncontrollable foaming, discontinuous production, low production capacity, high energy consumption, high production cost and cumbersome process. The pass rate of the product is low, and there are many problems such as low safety factor in production

[0003] In the Chinese patent with the patent number CN103993194B, a production system and production method of foamed aluminum are disclosed, which includes two intermediate frequency furnaces for continuous melting of aluminum, and each intermediate frequency furnace branch is connected with a mixing furnace through a moving runner , each mixing furnace corresponds to two foaming aluminum production lines, realizing simultaneous production of four production lines. The crucible dumping method is realized, and the two-way output cannot be realized, and the two-way continuous production is carried out.
