The degassing in the furnace is mostly in the static furnace. The refining media used for degassing are: flux, carbon tetrachloride, hexachloroethane, chlorine and other mixed gases. It is a good method for semi-continuous production. However, for continuous production, refining when the charge is transferred or half-charged will easily stir up the precipitated impurities, which […]

Although the melting process of cast aluminum alloy and cast copper alloy has its own characteristics, they still have several identical or similar links. Preparation before Smelting Before the melting process of cast alloy, carefully check the smelting equipment, smelting and preheating the furnace or crucible cavity, smelting and drying and preheating the charge. According […]

In the process of heating and melting aluminum alloy, both solid and liquid metals have the ability to absorb H2, O2, N2 and other gases. This property of metal is called gettering, which is one of the important melting characteristics of metals. Practice shows that the gas existing in metal in the state of adsorption, […]

Any melt treatment filtration and degassing are complementary, slag and gas cannot be completely separated. Under normal circumstances, slag is often associated with gas. The more inclusions, the higher the gas content in the melt. At the same time, the degassing process must also remove the melt. The inclusions in the body, while removing the […]

Corundum tube filter, ceramic foam filter, and deep bed filter have three different filtration methods. Although the structure is the same, the interception and capture mechanism of impurity particles is basically the same. No matter what kind of filter, the size of the particles that can filter out impurities is much smaller than the size […]

The filtration of primary aluminum is to allow liquid aluminum to pass through a filter composed of neutral or active materials, so that the inclusions in the melt are mechanically isolated, or chemically react with the active materials to separate the melt from the slag. There are many filtering methods for aluminum and aluminum alloys, […]

In order to meet the different requirements of different separation objects, filtering methods and equipment are varied. According to the filtration mechanism, two types of filter cake filtration are available: cake filtration and deep filtration. Filtration Mechanism In fact, the pore size of the filter medium used in filter cake filtration is not necessarily smaller […]

Filter medium filtration is an operation in which a certain porous substance is used as a medium to treat the suspension. Under the action of external force, the liquid in the suspension passes through the pores of the medium and the solid particles are intercepted, thereby achieving solid-liquid separation. According to the different places where […]

Ultra-thin high-speed casting and rolling technology aims to increase production speed, reduce slab thickness, improve slab quality, further refine grains, increase yield limit, corrosion resistance, impact resistance, reduce plate thickness and improve plate shape, and increase productivity, to reduce the number of subsequent cold rolling, and even achieve the goal of near net shape casting. […]

Electromagnetic casting and rolling (or called magnetic fluid casting) is to apply alternating special electromagnetic field in the casting area of ​​continuous casting and rolling of aluminum alloy to form aluminum alloy magnetic fluid casting and rolling technology. The purpose is to replace the effect of the modifier with the effect of the electromagnetic field […]
