Degassing

The degassing process involves bubbling dry, inert gases through the molten metal to reduce the hydrogen levels. Argon or nitrogen is the gas used for degassing aluminum. To be effective, very fine bubbles of the dry, inert gas must be generated at the base of the melt and allowed to rise through all areas of the molten aluminum. The rising bubbles collect inclusions and carry them to the top of the melt, where they can be skimmed off. You can use a lance with small holes in the end or a porous plug for degassing. Rotary degassing is the most efficient way to degas molten aluminum.

The rotary unit’s graphite rotor is lowered into the molten metal and spins as dry inert gas is introduced. The spinning of the rotary degassing creates very fine bubbles trapping hydrogen and inclusions, bringing them to the surface, leaving you with quality metal. You can introduce fluxes with an inert purge gas to further clean metal for an even cleaner melt.

Carpenter Brothers, Inc. has all the necessary products for your casting and shakeout operation. We have metal cleaners, slag coagulants, metal skimmers, and vacuum-formed skimmers to help ensure your castings are defect-free. In addition, we carry a wide range of pouring hand ladles and sampling spoons for ferrous or nonferrous applications. And after you have poured your casting, we have the right hot topping to apply. So take a look around; if you don’t see what you are looking for, give us a call or send us an email as there is a good chance we have it.

About Us

Carpenter Brothers, Inc. is the leading supplier of equipment, consumables, and technical expertise for the metal casting industry. Founded in 1917, by Everett and Milton Carpenter, the brothers were able to use their unique foundry experiences to solve the problem of the day: a reliable sand source.  They got their foot in the door by selling natural bonded molding sand, which was mined by hand, loaded into horse-drawn carts, and then delivered to customers.  Not only did they sell the sand, but their technical expertise was readily available for all customers, big or small, to help manufacture the best castings. After surviving The Great Depression, Carpenter Brothers, Inc. slowly increased the number of products it distributed and expanded its sales territory into what it is today.

 

Carpenter Brothers, Inc. has committed itself to its customer's success by providing exceptional service to go along with the superior products and equipment they supply.  With multiple warehouses around the United States we can get you the products you need when you need them. Our logistics team can handle getting your order to you by truck, plane, or train. Our technical sales and engineering staff all have experience in the industry, so when you buy from Carpenter Brothers you gain access to all of our knowledge.
