Fiberglass filter combo bag for aluminum alloy flat ingot

Fiberglass Filtration & Shunt Combo bag, also named Fiberglass filter combo bag, Fiberglass filter distribution bag, Fiberglass thermally fused shunt combo bag, which is weaved by special high-twist & high-strength alkali-free fiberglass yarn, special post-treatment, coated with resin and carbonized by high temperature. its withstand temperature up to 1000 °C.

Applications:

● Apply to filter large diameter aluminum ingot and billet, rectangular aluminium slab, and aluminum-alloy casting parts.

● Improve the temperature distribution of molten metal and control flow of aluminium vertical direct.

● Improve working environment, bags will be producing very little smoke, fumes or flame when molten aluminium flow inside, but it is harmless, no any affect to staff.

● Filter molten metal and decrease in non-metallic inclusions and oxide films in liquid metal.

● Improve mechanical quality of aluminum casting product.

● Improve the hardness of aluminum casting product with more average surface hard and bending strength.

Comparing to other filter bags, it does not affect the component of aluminum alloy, and with good filtration effect, high temperature resistance, high strength, excellent acid and alkali resistance, non-stick aluminum, non-slagging, non-peeling, as well as easy installation.

Main purpose:

● The liquid aluminum is divided between the two ends of the ingot, which determines the temperature distribution around the crystallizer device, and the temperature distribution will affect the metallographic structure of the cured aluminum alloy ingot.

● The second purpose is to keep the oxide in the bag, reduce the aluminium flow and filter out all the large particles that mainly include alumina, chloride and titanium, Boron, magnesium oxide and large resistant material shed.

Fiberglass Filtration Combo bag is a process in contact with liquid aluminum in casting foundry, so it is very important and is considered to be the key to achieve the casting quality standards of aluminum and aluminum alloy flat ingot.
