Alumina ceramic foam filter
The product, adopted good portiforium foam and high purity ceramic , effectively removes non-metal solid mixture from aluminium and aluminium alloy fusant.
Application:
For the filtration of molten steel and alloy,large scale iron casting
Product standard:China national GB/T 25139-2010
Zirconia ceramic foam filters are determined for filtering of steel and steel alloys up to the temperature of 1700 °C.
Filters are recommended especially for high quality grades of alloys.
-Drop turbulent of molten steel and alloy
-Improve accepted rate of steel casting
-Reduce foreign matter of steel casting
-Drop twice oxide flaw
-Reduce second-face flaw after machine process
Advantages:
even aperture, high porosity, proper sinter, high strength of anti-flexing and anti-compression, effective filtering.
It is widely applied to the aluminium fusant filter equipment of continuous casting, half-continuous casting, gravity casting, and low pressure casting.
Ceramic foam filters are different from aperture specifications from 10 to 45ppi, with different sizes and shapes.
Besides the general specification ,we can offer the product according to the customers requirements.

- Q:Can the plate filter press pass through the filter plate?
- There are many types of pumps to be used, such as screw pumps, slag pumps, rotary pumps, piston pumps, and diaphragm pumps.
- Q:What about the leakage of the ceramic filter static and dynamic sealing points?
- When the ceramic filter works, the operation may be as follows: 1. The feed is injected and the pulp is injected into the tank of the ceramic filter. 2, mixing system, ceramic filter stirring rake back and forth mixing, driven by mixing reducer. 3, spindle rotation, material level reached a certain range, through the spindle speed machine to drive the ceramic filter disk rotation.
- Q:What is the backwashing pressure of the ceramic filter?
- It should be said that the ceramic filter backwash, usually with a certain pressure of clean water to backwash.
- Q:What is the reason that the ceramic filter does not absorb mineral powder?
- There may be a fault filtrate pump, diaphragm pump damage, pump mechanical seal failure, a leak, two is no output or output to the liquid, the pressure is too low, the cleaning effect is not good, the pressure is too large, will cause damage and reduce the concentration of slurry filter plate.
- Q:Beneficiation ceramic filter no problem, the technical parameters are normal, but filter out the concentrate water suddenly excessive, what is the reason?
- First, the fineness of the material, resulting in the filter board filter cake moistureTwo, the vacuum can not reach, in the circumstances, whether the vacuum pipe leak
- Q:The ceramic filter plate is broken. What will happen to the vacuum pump?
- That's a good question. I hope my answer will help you.Ceramic filter ceramic plate broken, nothing more than ceramic plate plug and ceramic plate rupture, you should be the problem of ceramic plate rupture.
- Q:What are the materials that make up the ceramic mold?
- At present, the commercialized porous ceramic membranes are mainly composed of 3 types: flat plate, tubular and multi channel. Flat film is mainly used for small-scale industrial production and laboratory research. The tubular membrane is combined with rice to form a heat exchanger similar to a column tube heat exchanger, which can increase the loading capacity of the membrane, but is gradually withdrawn from industrial application due to its strength problem. The size of the applied ceramic membrane usually adopts a multi channel configuration, that is, a plurality of channels are distributed on a circular cross-section, and the number of general channels is 7, 19 and 37. The main business of the inorganic ceramic membrane preparation technology: using solid particle sintering preparation carrier and microfiltration membrane by sol-gel method in the preparation of ultrafiltration membrane: glass membrane by phase separation method: using special technology (such as chemical vapor deposition, electroless plating, etc.) the preparation of microporous membrane or dense membrane. Its basic theory involves colloid and surface chemistry, material chemistry, solid state ion science, material processing and so on.
- Q:What's the acid of the ceramic filter plate?
- Ceramic filter boards tend to clog and acid washing is used to dissolve and dredge blockages in their pores.
- Q:How can I avoid the backwash pressure in the production of ceramic filter?
- The backwashing system of ceramic filter is usually made up of water inlet, water inlet, pressure gauge, water filter and filtered water pressure gauge, and then connected to the inside of ceramic filter. Such as the discovery of ceramic filter recoil pressure became smaller or even no recoil pressure, you can carefully observe the surface of the ceramic filter plate is wet or ceramic filter plate wear without water injection at the discharge point, investigation and the reasons for the following aspects:Is the water inlet pressure or normal?How about the sealing performance of the water filter? Does the filter element need to be replaced?Is the recoil system piping (metal pipe, ceramic filter plate, connecting pipe, etc.) broken, leaking or dripping?Is the distributor valve properly installed and is it worn?Are there any cracks in the ceramic filter plate?Is the pressure gauge broken?The most likely reason is 1, 2, two, the best water should not be too dirty, filter should be replaced regularly. I hope the answer can help you.
- Q:Excuse me, what's the reason that all ceramic filters do not attract ore?
- After the joint cleaning, 0~2 hours of suction effect may be good, 2~4 may drop slightly, 4 hours later will become worse and worse, or even suck. This case should first check the backwash water pressure (instantaneous maximum pressure should not be less than 0.08MPa) is to meet the requirements, should also advance down (to ensure normal and ultrasonic cleaning combined with nitric acid dosage sufficient) and prolong the cleaning time.
