Alumina Ceramic Foam Filter Aluminium Korba filters out impurities, gases and certain harmful elements in the aluminum melt through the filter (main body) in the process of casting or casting salt.
The principle is adsorption filtration and mechanical filtration.
It greatly improves the mechanical properties of aluminum alloy filter castings, and can increase the strength, toughness and elongation.
After the molten aluminum is filtered, the quality of ingots and castings is also greatly improved.
There are many lead melt filtering materials, such as glass cloth, refractory fiber mesh, magnesium fluoride, calcium fluoride and so on.
For Asian casting filter agent, please contact the Chinese manufacturer

Aluminum and its alloys are prone to oxidation and gas absorption during the smelting and casting process, and defects such as inclusions and pores are easily formed during the die-casting process, which is not conducive to the alloy structure, thereby reducing the mechanical properties and the corrosion resistance of the alloy. And reduce output.
Therefore, reasonable control of the smelting process and improvement of the quality of aluminum melt are the key to improving the quality of aluminum die castings.

Alumina Ceramic Foam Filter Aluminium Korba

Today, there are many ways to remove these harmful substances and purify the aluminum melt.
According to the different methods, these methods can be divided into two categories: in-furnace processing and out-of-furnace continuous processing (ie online processing).
According to the function, it can be divided into main degassing and slag removal. Ceramic casting filter manufacturer ( introduced a method of continuous filtration of aluminum melt using foam ceramic filter plates. External continuous treatment, the main purification operation is slag removal.

Alumina Ceramic Foam Filter Aluminium Korba has a certain strength network structure, which can withstand the influence of the pressure difference of the metal liquid level and the metal flow, but it is brittle. Due to the precise structure of this material, uniform quality, large surface area, and excellent filtering effect.

In order to solve this problem, a simple filter made of wire mesh, perforated steel plate, etc. is inserted into the gating system to remove impurities from the beginning.
Inner filter with two-dimensional structure such as silicate needle fibers and boron nitride fibers.
Nowadays, ceramic foam filters use pore sizes to mechanically intercept large mixed oxide particles, while filter cakes are used to filter small mixed oxide particles.
It also has the functions of adsorption and rectification. The production line using ceramic foam filters has significantly increased the output of castings.
