Longzhiyi molten aluminum filter box is a high-temperature refractory filtration chamber specially designed for aluminum foundry operations and continuous casting production. When used in conjunction with ceramic foam filters, it effectively removes oxide slag, inclusions, and micro-impurities from molten aluminum. This filter box stabilizes molten aluminum flow, reduces casting defects, and significantly improves the surface quality and mechanical properties of finished aluminum products. Boasting excellent thermal shock resistance, low heat loss, and long service life, it is an essential purification equipment for modern aluminum alloy casting facilities.
The molten aluminum filter box is installed on the molten aluminum flow channel before casting. After high-temperature molten aluminum enters the filter box, it passes through the precision ceramic foam filter plate inside the unit. During penetration, solid slag, oxide impurities, and tiny suspended particles are intercepted and adsorbed onto the filter. Purified molten aluminum then flows out steadily in a laminar state, avoiding secondary turbulence and oxidation. This purification process effectively improves the purity of molten aluminum and greatly increases the yield of qualified aluminum castings.
The molten aluminum filter box is a professional refractory filtration device for aluminum foundry and continuous casting. It is used to install ceramic foam filter plates, remove oxide slag, inclusions and tiny impurities in molten aluminum, stabilize liquid flow, and improve aluminum casting quality while reducing casting defects and scrap rate.
Our aluminum liquid filter box is made of high-strength aluminum silicate refractory material and high-temperature resistant fiber. It features low thermal conductivity, excellent thermal shock resistance, no cracking, no peeling, and can work stably under 1250℃ high-temperature molten aluminum environment.
Yes. Compared with disposable filter plates, our refractory filter box has a long service life and can be reused for a long time with regular cleaning and standard operation. It greatly reduces the overall production cost for aluminum foundry factories.
Our aluminum filter box is perfectly compatible with standard ceramic foam filter plates for aluminum casting. Multiple specifications such as 10PPI, 20PPI, 30PPI, 40PPI are available to meet different precision casting requirements.
No. The inner surface of our filter box adopts special anti-sticking treatment, which effectively prevents molten aluminum adhesion. It ensures smooth aluminum liquid flow and makes cleaning and replacement more convenient.
Absolutely. We support full customization according to customers’ casting line size, flow rate requirement and equipment structure. Custom length, width, height and outer steel frame structure are all available.
Our standard molten aluminum filter box can work continuously at 1100℃-1250℃, which fully meets the working temperature requirements of conventional aluminum alloy casting, aluminum billet casting and aluminum profile production.
The optimized inner cavity structure changes turbulent flow into stable laminar flow, avoids secondary oxidation of molten aluminum, and effectively filters slag and impurities. It significantly reduces casting porosity, trachoma, cracks and surface blemishes, improving the finish and mechanical properties of aluminum products.
Yes. The low thermal conductivity material effectively reduces heat loss during aluminum liquid transfer, keeps stable molten aluminum temperature, reduces repeated heating times, and saves energy consumption for foundry production.
