                               High Quality Zirconia Ceramic Foam Filter for Steel Casting Industry

Product Introduction

The ceramic foam filter has an excellent filtering effect on the copper water or the molten iron. By using the three-dimensional structure, it can effectively remove the oxide inclusions and other non-metallic inclusions by blocking the adsorption. Whether gray iron, ductile iron or shaft, cylinder or complex large parts, precision metal parts are filtered, the product quality will be satisfactory results.

Product Feature

  1. Reduce the defect rate of impurities:The inclusion defect reduced by more than 50%.
  2. Improve casting performance:Increased tool life by more than 30%.
  3. Improve casting mechanical properties:Mechanical improvement over 10
  4. Improve casting process production rate:Process production rate increased by more than 10

Aperture and Size selection of foam ceramic filter

When using rare earth foam ceramic filter, according to the number of inclusions in the quality needs of the casting and metal liquid to determine the filter pore size (inches product number of holes, PPI) filter aperture is divided into 10 PPI, 15 PPI and 20ppi, 25 PPI and 30 PPI specification products. Ductile iron castings for general use 10 PPI or 15 PPI specifications products, grey iron, copper casting.

General use 10 PPI, 15 PPI or 20 PPI specifications of products, aluminum alloy castings generally use 20 PPI, 25 PP or 30ppi specifications of the product. Rare earth foam ceramic filter thickness, the filter's strength is better, but its use cost is also higher. From the most appropriate intensity and filtration efficiency considerations, the general recommendation is as follows: 75-120mm, thickness 22 ~ 25mm, 25 ~ 30mm, 120 ~ >150mm, 25~30mm, 150mm, 30 ~ 40mm.

2.Size selection of rare earth foam ceramic filter

The size of the rare earth foam ceramic filter with the type and size of the casting two aspects to determine. Rare earth foam ceramic filter unit cross-sectional area of the maximum liquid metal filtration should generally be controlled within the scope of the following: nodular cast iron is equal to or less than 2kg / C square meters; gray cast iron, copper and aluminum alloy cast piece is less than or equal to 4kg/c square meters. The conventional rare earth foam ceramic filter filter size amount as shown in the following table

Application

Ceramic foam filters are also suitable for copper, bronze, brass and other copper alloys, reducing the turbulent copper flow and rectifying and purifying the molten copper. Particularly valuable is the fact that the filtered and purified copper castings have a significantly longer lifetime in demanding or harsh environments such as offshore marine turbines, chemical parts, etc., and also have good results for cast copper parts with surface polishing requirements. The ceramic foam filter also plays an important role in the traditional copper industry, electrical and electronic copper industry, and continuous casting and rolling. As copper and alloys, such as zinc alloys, have a greater weight, they produce greater Thermal shock, so in the copper casting process, the use of silicon carbide ceramic foam filters are generally strictly sized.
