Aluminum continuous casting rolling is a process of directly producing semi-finished strips or finished strips by using liquid metal as raw material, two casting rolls opposite in rotation direction as crystallizers, and applying a certain rolling force. Before metal continuous casting and rolling, the casting tip and nozzle are dried and preheated in the baking […]

The casting tips and nozzle, vacuum-formed headbox and tundish are the key factors to ensure aluminum coil casting and rolling production. After lowering the vacuum-formed headbox and tundish (also called front box) temperature, the coarse grain defects caused by the excessive temperature can be reduced, the oxidation slagging reaction of the melt at high temperature […]

The inclusions of molten aluminum have a great impact on the use of aluminum plates, so the removal of inclusions must be strictly controlled during production. The main causes of inclusions are: (1) In the process of feeding and stirring, the oxide film formed on the surface of the melt is damaged and mixed into […]

Aluminum melt purification method adopts the bubble floatation method for three refinings, blowing N2+ high-temperature treatment agent into the melt, and on-line purification outside the furnace uses CCl4+N2 to be sprayed through the graphite rotor rotating, and the slag is pulled out in time to ensure the quality of the melt. After a series of […]

The size of gap in nozzle and roller has a great influence on the longitudinal streaks. In normal production, due to the assembly error of the nozzle or the poor quality of the nozzle, the gap in nozzle and roller is too small or partially uneven. The powders ground by the nozzle after the roll […]

The vertical slab stage is the prerequisite for the aluminum sheet normal production of casting and rolling. From the vertical slab, the influence of the adjusted casting nozzle on the flow of molten aluminum can be observed. Vertical Slab Stage for Aluminum Sheet Production When the liquid level of the front tank reaches a certain […]

Aluminum continuous casting and rolling combines casting and hot rolling in the aluminum strip forming process, greatly shortening the production process and production cycle, and has become one of the main methods of aluminum processing and production of strips. On the basis of optimizing the structure of the casting-rolling nozzle cavity and increasing the gap […]

After a certain period of degassing and filtering, the molten aluminum begins to enter the molten aluminum hot top casting stage. At this stage, the casting speed starts to rise from the initial speed to the normal casting speed, the casting temperature also starts to rise to the normal casting temperature, and the cooling water […]

Sound metal is used to refer to the quality of the molten metal immediately before casting, which means the removal of dissolved hydrogen and non-metallic impurities from the molten metal. When the metal solidifies, the solubility of hydrogen in the aluminum alloy decreases by about an order of magnitude. Therefore, if the hydrogen content of […]

Aluminum Casting Foundry Filter has been used for commercial purposes in the foundry industry, and has been used in the aerospace industry to produce high-quality aluminum castings for such products for more than 40 years. In recent years, CFFs have been increasingly used in the non-ferrous and non-ferrous metal industries. The non-ferrous metal industry is […]
