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 […]

The Covering Results of flux for aluminum covering agents are applied to the actual production of a recycled aluminum enterprise in Guangdong, and the refining effect is compared with the domestic high-efficiency flux (code-named A) and imported high-efficiency flux (code-named B). The test process is as follows: the regenerated aluminum alloy melt (ADCl2) in the […]

The design goal of  the flux for aluminum casting Given the many deficiencies of the current domestic and foreign fluxes, this topic intends to develop a new multi-functional granular refining flux with slag removal as the main and degassing as the auxiliary, which can achieve the following goals (1) The new the flux for aluminum casting […]

Production equipment: The alu flux mostly contains various Na and Ca-containing components, such as NaF, Na2SiF6, Na3AF6, CaF2, etc. After refining, excess impurity elements Na and Ca be introduced into the melt. In addition, the preparation process of the flux is easily overlooked. At present, the alu flux is prepared by mechanical mixing method, and […]

Based on the current refining and many existing problems, as well as comparing foreign products, refining flux Improvement imminent.   Foreword In September 2020, President Xi Jinping proposed at the general debate of the 75th United Nations General Assembly that my country should strive to achieve carbon neutrality by 2030 and 2060. On April 30, […]

the research method of ceramic filter for casting. 1.3 The significance of the topic selection and research content This work is to develop a large-area porous ceramic filter plate with high porosity and high strength in response to the requirements of a large domestic aluminum plant for the filtration of aluminum alloy melts. This work […]
