In order to prevent the oxidation process from reducing the value of the metal, aluminium facilities mostly use dross press machines. When hot dross is removed from the furnace, it still contains a significant amount of liquid aluminium, and for every minute that it is exposed to air, aluminium is lost to oxide. This problem is directly addressed by an aluminium dross press machine, which presses the liquid metal out while simultaneously preventing the material from being exposed to air. Through the use of this dross press equipment, plants are provided with a quick and dependable method to cut down on metal losses before they accumulate during melting operations. The Problem: Oxidation Eats Into Aluminum Value Metal dross is a mixture of liquid aluminium, salts, oxides, and other compounds. As soon as it is removed from the furnace, it begins to react with air. This process continues until the dross is completely removed. The more time the heated dross is left exposed, the more of th

Every aluminium plant that pours remelt ingots has to deal with the same problem: why do some ingot mold sets last for years while others break, bend, or need to be replaced in just a few months? Most of the time, the answer isn’t caused by operator mistake or bad pouring technique. It all comes down to the steel. An ingot mold is a shallow, open container that holds molten aluminium for just long enough for it to solidify into a transportable ingot. However, the metallurgy behind that simplicity is what makes the difference between years of reliable service and repeated, expensive downtime. Why Ingot Mold Life Comes Down to the Steel? An ingot mold doesn’t have a built-in way to cool it down, control the temperature, or have any moving parts. The main part of it is a container that is made to hold molten aluminium and let it cool naturally. The base material is so important because it is so simple. Every time a pour happens, the mold quickly goes from hot to cold: high-te

When aluminium is first smelted, the casting equipment that is used has a big impact on how well the plant works and how the operations run. It is now known that high profile sow molds are a unique shape with unique dimensions that affect choices about how to lay out a facility. Unlike smaller ingot mold systems that are made for making lightweight castings, a sow mold can hold large amounts of molten aluminum—usually 1200lb, 1500lb, or 2000lb—making big blocks that can be sold to other industries. By weighing the pros and cons of different high profile sow mold designs, aluminium plants can choose the right tools for their production goals and space limitations. Space Efficiency and Operational Advantages of High Profile Sow Molds Aluminium smelting facilities benefit from high-profile sow molds’ vertical extension, which occupies less space on the casting floor while accommodating the same aluminium volume. This tiny foundation is useful in facilities with limited floor space
