CFF ceramic foam filter plates are popular because of their low cost, compact structure, simple operation, and better filtering effect. Compared with the corundum tube, the CFF ceramic foam filter has a larger pore diameter, a smaller density, and a lower filtration accuracy. Compared with the deep-bed filter, the filter layer is thin, and there […]

The smelting process of waste aluminum determines the performance of secondary aluminum products. The aluminum melt production process is roughly as follows: batching-furnace loading, melting-alloying-stirring-furnace treatment-on-line treatment outside the furnace (degassing, filtering, etc.)-casting. The treatment in the furnace is one of the key processes that affect the quality of molten aluminum, which mainly includes the […]

The molten aluminum purification stage refers to the process in which liquid aluminum is transferred from the static furnace into the launder, after online degassing, ceramic foam filter molten metal filtration, etc., filling the draft tube and keeping it for a certain period of time. At this stage, the three elements required for casting: casting […]

The aluminum hot-top casting process is selected for the production of aluminum alloy round ingots, it has the advantages of excellent internal and surface quality of the ingot and easy production and operation. Under the condition that the composition of the alloy and the hot-top casting process equipment are determined, the casting process parameters are […]

The aluminum ingot produced by hot top casting has a uniform structure and good mechanical properties. In order to obtain such a casting structure, aluminum ingot hot top casting is used for round ingot casting. The quality of aluminum alloy ingots has an important impact on the subsequent processing procedures and the quality of aluminum […]

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 […]
