Modification of cutting surface of foam cutting machine With the increasing demand from domestic and foreign customers for our company’s ceramic filter plate products, the current cutting accuracy of the filter board foam body cannot meet customer needs (the original cutting diameter accuracy of the ceramic foam filter was+1mm, -2mm, and the current accuracy has been […]
1. Background The briquetting is used in the casting and rolling production line. When in use, the briquetting is placed on top of the porous ceramic filter to prevent the alumina ceramic foam filter from floating during the casting and rolling process. The general service life is 3-6 months; the product needs to have sufficient density and […]
Recently, the quality inspection and the quality department have frequently responded to the ceramic foam filter sprayed dead hole. The quality department has several assessment items for the workshop, and the production internally finds the cause and analyzes the root of the problem. ceramic foam filter sprayed dead hole–Problems in the spraying process: Spray A on […]
ceramic filter plate: Filter-PAl filter plate uses organic foam with a three-dimensional network structure and connected pores as the carrier, and invades it into the thixotropic Al20s material slurry, and adopts the automatic extrusion process of square correction center distance to make the slurry The material is evenly coated on the foam body skeleton of […]
Definition of refractory clay It is composed of refractory powder, binder, and admixture. Ordinary refractory mud made of refractory clinker powder plus an appropriate amount of plastic clay as a binder and plasticizer has low strength at room temperature, and it has higher strength when it forms a ceramic bond at high temperature. The chemically […]
The inclusions in the aluminum melt mainly include solid inclusions and gas inclusions. The solid inclusions are mainly Al2O3, AlN, Al3C4, and MgO produced by the reaction of aluminum and its alloys in the smelting process with N2, O2, and CO2 in the furnace gas. Finally oxidized to Al2O3, MgAl2O4; The methods for removing inclusions […]
Porous ceramic filter is a porous medium with a three-dimensional through-network structure. It has good chemical stability, high specific strength, high-temperature resistance, thermal shock resistance, and a large specific surface area. It is widely used in the filtration and purification of high-temperature melts in the metallurgical industry. Its filtration The purification mechanism is mainly manifested […]
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 […]
“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 […]
CFF Filter for Molten Aluminium Filtration is a ceramic foam filter made of molten metal passed through neutral or active material to remove suspended inclusions in the melt. As the molten aluminum alloy stream passes through the tortuous path of the ceramic foam filter, non-metallic inclusions are trapped within the ceramic structure. The filtered metal […]
