Carborundum foam ceramic filter/piece/web

The basic material of “DERGNS” series of carborundum foam ceramic filter is carborundum. Carborundum has a great intensity and endurance of high-temperature and chemical erosion.

“DERGNS” carborundum filter web can endure 1560℃ or so. Therefore it can be used in the foundry of all the copper alloys and the cast iron.

“DERGNS” foam ceramic filter can obviously enhance the quality of cast iron accessories and reduce the proportion of wasters. “DERGNS” filter web can also be used in the technique of continuous casting continuous rolling.

“DERGNS” carborundum foam ceramic filter web can perfectly filter the copper liquid or the iron liquid, with its perfect three-dimensional structure to block off, adsorb and effectively eliminate oxidated and other nonmetal impurities. No matter it is the gray iron or ductile iron, shaft or cylinder or complicated large piece or elaborate hardware accessories, as long as it is filtered by “DERGNS” carborundum foam ceramic filter web, its quality will be very stable and satisfactory.

The outstanding raw materials and the advanced production technique guarantee “DERGNS” carborundum foam ceramic filter web with stable tolerance of size and meet the requirement of handmade sculpt and more efficient mechanized production lines and also guarantee that the products in the foundries can meet the international quality standard.

“DERGNS” carborundum foam ceramic filter web can also be used in purifying the melted liquid of copper, bronze, brass and other copper alloys. It is very valuable that the copper casts, which have been filtered and purified already, show their extended lifespan as the turbines of the ships and chemical parts or in the severe conditions. As to the copper casts that require polishing the surfaces, it also represents the great effect.

In the traditional copper manufacturing industry as well as electric and electronic copper manufacturing industry and the techniques of continuous casting continuous rolling, “DERGNS” carborundum foam ceramic filter web also plays an important role. Because the specific gravity of cooper and alloys such as zinc alloys, etc is larger and the thermal impact during the foundry is greater, in the techniques of casting copper, there is no strict regulation for the size of carborundum foam ceramic filter web.
