Melt casting apparatus and melt casting method
By using flow-limiting pipes and flow-limiting components in the casting device, the flow rate of the casting liquid is controlled, which solves the problem of aluminum alloy splashing when it first enters the mold cavity, thus improving the quality of the ingot and production efficiency.

AI Technical Summary
Technical Problem
When aluminum alloy first enters the mold cavity, it is prone to splashing and contact with air, which leads to excessive oxidation and affects the quality of the ingot.
Method used
The system employs a flow-limiting tube and flow-limiting component structure inside a high-temperature resistant tube. By controlling the flow rate of the casting liquid through the through-hole of the flow-limiting tube and the movable blocking or opening of the flow-limiting component, splashing and oxidation are reduced.
Benefits of technology
It effectively reduces the splashing of casting liquid, avoids excessive oxidation, and improves the quality consistency and production efficiency of ingots.

Abstract
This application relates to the field of casting technology, providing a casting apparatus and a casting method. The casting apparatus includes: a sand mold having a cavity and a sprue communicating with the cavity; a high-temperature resistant tube disposed within the sprue; a flow-limiting tube disposed within the high-temperature resistant tube and forming a flow-limiting space between the tube and its inner wall, the flow-limiting tube having multiple through holes on its wall communicating with the internal space of the high-temperature resistant tube and the flow-limiting space; and a flow-limiting element movably disposed within the flow-limiting tube for blocking or opening the through holes. The casting apparatus and casting method provided by this application can limit the casting flow rate, reduce casting splashing, and prevent excessive oxidation.
