Thermally Formed Rigidized Combo Bags For Aluminum Casting Filtration

Brief Introduction:

Thermally Formed Rigidized Combo Bag, also named TF Combo Bag, which is weaved by special high-twist & high-strength alkali-free fiberglass yarn, special post-treatment, coated with phenolic resin and suitable "carbonized" by high temperature.

Applications:

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

Purpose:

● Improve mechanical quality of aluminum casting product.

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

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

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

● 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.

● 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. 

● 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.

Advantages: 

Thermally Formed Rigidized 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.

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.

Hebei Cangchen, as a professional developer, designer and manufacturer of such bags, we have accumulated a considerable amount of experience during producing these bags to our global customers, who are from USA, Russia, Spain, Luxembourg, Italy, Brazil, Mexico, India, Pakistan, Vietnam and so on, we have produced many dimensions, such as: 18"x10"x6", 18"x5"x6" and 13"x5"x6". Our bags have been certified by MSDS(USA edition).

Today, Such TF Combo Bags are exported to India for their test.
