1. Principle of aluminum alloy deep bed filtration Aluminum alloy deep bed filtration is a physical filtration technology. Its principle is to use the setting and screening function of the filter material layer to filter out suspended solids, impurities, and particulate matter to achieve the purpose of purification. The properties of the filter material determine […]

As an amorphous refractory material, refractory castables are often used in parts with complex shapes and surfaces, because these parts are not suitable for masonry with refractory bricks, and it is difficult to ensure stability under working conditions. Size and positioning of nails in the refractory castable lining. The castable is combined with the shell […]

1. Clean up before pouring: Normally, workers will clean the mixing pot after production, but during the production process, it is temporarily impossible to clean the mixer after each pot of ingredients is mixed. The cleaning is as shown below: (Is it possible to pour strong and dense materials first and then smaller ones during […]

Preparations before the use of cartridge filter cartridge filtration principle: The molten aluminum entering the cartridge filter equipment contains Various impurities and large particles are filtered out by the surface media of the filter tube, while small particles are filtered out by The media inside the filter tube is adsorbed, and pass through the double […]

There are many types of refractory materials with a wide range of uses, and their classification methods are various. The following are commonly used Steps/Methods Refractory materials can be divided into 8 categories according to their chemical and mineral composition: 1. Silicon material 2. Aluminum silicate material 3. Magnesium materials 4. Dolomite material 5. Chromium […]

How to choose aluminum degassing equipment Selecting the appropriate degassing equipment for aluminum liquid requires consideration of multiple factors, with the following being some key considerations:   1 de-aeration requirement The first thing to consider is your degassing requirement. Different processes and applications may require different types and specifications of degassing units. Determine the type […]

The operation of Northwest Aluminum Online Degassing Equipment meets the requirements As of June 27, 2023, the Northwest Aluminum production line has been in operation for some time, and the hydrogen content at the outlet of the degassing equipment has decreased to 0.11ml/100g-AL, which does not meet the customer’s high degassing requirements (0.1ml/100g-AL). At the […]

Modification of cutting surface of foam cutting machine With the increasing demand from domestic and foreign customers for our company’s ceramic filter plate products, the current cutting accuracy of the filter board foam body cannot meet customer needs (the original cutting diameter accuracy of the ceramic foam filter was+1mm, -2mm, and the current accuracy has been […]

1. Background The briquetting is used in the casting and rolling production line. When in use, the briquetting is placed on top of the porous ceramic filter to prevent the alumina ceramic foam filter from floating during the casting and rolling process. The general service life is 3-6 months; the product needs to have sufficient density and […]

For the technical transformation project of the 16-ton melting and casting production line of Northwest Aluminum Co., Ltd., our company designed an online degassing unit, plate filtration, deep bed filter, and online heating launder system for the northwest aluminum production line. From design liaison, design review, production and production, inspection and acceptance, on-site installation and […]
