The aluminum liquid rotary degasser is an online device for aluminum and aluminum alloy melts in the casting process, and its function is to greatly reduce the hydrogen content in the aluminum liquid and improve the quality of aluminum and aluminum alloy products. During the degassing process of the degassing box, the oxygen content in […]

What are the characteristics of a liquid aluminum rotary degassing A kind of aluminum liquid rotary degassing as claimed in claim 4, is characterized in that, the straight line that the bottom surface center point of described outlet interface launder forms is tangent to the lowest point of the curved surface structure of the described bottom […]

A liquid aluminum degassing box and an aluminum liquid degassing unit (57)Summary The utility model provides a liquid aluminum degassing box, which belongs to the technical field of metallurgical equipment. The liquid aluminum degassing box includes a box body and a box cover; the box body includes a box wall and a hollow cavity arranged […]

Grout spraying amount of ceramic foam filter   The amount of slurry spraying is an important index to measure whether the spraying effect is ideal   It is also an important factor to determine whether the spraying of each green body is uniform. So many   The company will index it and set specific parameters […]

Grouting method of ceramic filter plate, manual glue spraying process, grouting sequence 3.1 Grouting method   3.1.1 Manual guniting process   Manual spraying is the pressure generated by the air compressor (0.5~1. OMPa)   Force, spray the slurry from the spray gun, and spray it on the surface of the green body under the control […]

Applied Research on Shotcrete Technology of Alumina Foam Ceramic Filter Plate 1 Prefacee Foam ceramic is a kind of three-dimensional space grid structure with a high air-void ratio (80% – 90%) porous ceramics, due to their low density, high strength, and high resistance Temperature, corrosion resistance, and good filtration and adsorption. Therefore, it is widely […]

Recently, the AB foam insulation self-flowing material developed by our company has been improved according to the different needs of many customers, and industrial verification has been carried out on the cast rod plate. The material has low density, low thermal conductivity, and a good heat preservation effect. At the same time, the material has […]

“The aluminum extraction process“. Since the advent of the foam ceramic filter plate technology in the 1970s, it has shown great vitality in producing aluminum and aluminum alloy materials. With the development of society, the quality requirements of aluminum products are getting higher and higher, and the application of ceramic filter plates will become more […]

“purifying aluminum“.     1.1 Research on sintering mechanism 1.1.1 DSC differential thermal analysis Figure 4-1 shows the measured DSC-TG curve. The exothermic peaks in the figure are 146°C, 570°C, 663°C, and 388°C, and the endothermic peaks are 614°C and 1119°C. 146°C is the temperature at which the polyurethane foam begins to soften: 570°C is […]

Therefore, it can be inferred that both SCUT-type and B-type the aluminium casting flux have a better-degassing effect, the degassing ability is comparable, and is better than A-type refining flux. It can be seen from Figure 9 that the number of pinholes on the cross-section of the pinhole sample before refining is large. After the […]
