It determines whether aluminum alloy materials have metallurgical defects and high-performance heritability, and dominates its application and development in various fields.
In casting and rolling production, the amount of melt filtration per unit time is small, and the flow rate is slow. Casting and rolling are mostly pure aluminum and soft alloys, and the green body is easier to purify. Generally, 50ppi and 30ppi two-stage degassing unit are used. The thickness and area of the filter can be determined according to specific overflow calculations to meet t degassing unit requirements.
Compared with casting and rolling, the production situation of castings is more complicated. The flow rate is large, and the filtering method of the filter is the same as that of casting production.
The filtering flow is equivalent to more than 253.5 times that of the pouring roller, which reduces the filtering... less
