Electrolytic aluminum liquid purification is important for aluminum factory. Aluminum foundries use more stringent purification processes to ensure the purity of the aluminum melt. In production, after six times of purification, slag discharge and degassing, to ensure the effect of melt purification. The temperature of the electrolytic aluminum solution is as high as 950°C, which […]

LHC Casting System is advanced molten aluminum casting technology, uses electrolytic raw aluminum liquid to directly produce aluminum alloy slab ingots. The quality of aluminum and aluminum alloy ingots is closely related to the quality of final processed products and the yield rate. Defects that are not easy to detect or detect during the smelting […]

Aluminum alloy quality control is important for aluminum melting. Melting and pouring of aluminum alloy is the main link in casting production. Strict control of the whole process of melting and casting plays an important role in preventing casting defects such as pinholes, inclusions, under casting, cracks, pores and shrinkage porosity. Due to the high […]

In the production of sheet, strip, and foil, the quality of cast rolling plate is one of the key factors affecting the product quality. There are many factors affecting the shape of cast rolling plate, among which the hot charging quality of casting roll, the grinding precision of casting roll and the establishment of main […]

Airway defects in continuous casting can be divided into mild and severe cases. On the cross-section of the cast rolling plate, there are some micro holes in the cross-section of the cast rolling plate, which are not continuous crystallization, but holes appear in the serious cases. Air passage is a serious defect in the production […]

Cracks defect in casting is a common problem. The main reason for the cracks is that the temperature difference between the surface and the center is large during the casting and rolling process in the casting and rolling area. The surface layer is not easy to deform due to the low temperature of the surface […]

Tropical defect in continuous casting is that the liquid metal aluminum in a certain part of the casting and rolling area, only completes the crystallization process, but is not affected by the roll casting, and is brought out by the casting roll in the solidification state. Tropical Defect in Continuous Casting Causes When the temperature […]

The aluminum strip continuous casting and rolling process is an advanced production process introduced from abroad in the 1980s. Continuous casting is a process of casting and rolling. The liquid metal aluminum is continuously supplied from the casting source of the casting roll through the caster tips and nozzles, and the cast-rolled sheet is cast […]

Continuous casting and rolling method has simple equipment and low investment. For the production of certain aluminum alloy grades, it can replace the traditional hot continuous rolling method of aluminum ingots with large investment and high cost. It can not be cast and rolled by aluminum ingot rolling. The resulting fine microstructure is more suitable […]

There are mainly two purification methods for removing impurities: flux method and molten aluminum filtration method. Due to the interaction between inclusions and hydrogen in liquid aluminum, hydrogen removal and purification methods for aluminum have varying degrees of impurity removal. Because the degassing method used to remove impurities is very limited, a molten aluminum filtration […]
