White color TF Combo Bag for molten aluminum filtration

Fiberglass Filtration & Shunt Combo bag, also named Fiberglass filter combo bag, Fiberglass filter distribution bag, Fiberglass thermally fused shunt combo bag, TF 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.

There are two colors due to resin is coated or not. One is white color without coated resin, the other is deep yellow or brown color with resin coated.

TF Combo Bag is one of process in contact with aluminum liquid in casting foundry, so it is quite important.

It is the key to achieve the casting quality standards of aluminum and aluminum alloy flat ingot if bags and skimming ring are used together.

Main purpose of usage of such bags:

1. The aluminum liquid is divided to two ends of ingot through the bags, this process will determines the temperature distribution around crystallizer device. And the metallographic structure of the cured aluminum alloy ingot will be affected by the temperature distribution.

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

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.

We have many years experiences in producing such TF Combo Bag and exported to many countries with our OEM service.
