Ceramic Foam Filters

Zirconia for Steel Foundries

 

 

Characteristics

 

Ceramic Foam Filters are designed for the filtration of molten steel, alloy steel, and especially for high quality steel alloys casting temperature up to 1700 °C , which have high porosity (76%-82%), high thremal shock resistance and large specific surface.

 

 

 

Advantages

 

Ceramic foam filters help to enhanced quality of castings and reduce cost.

 

l  Special 3D structure to reduce turbulence of flowing molten metal.

l  Reduce defective rate of castings.

l  Improved mechanical properties of castings.

 

l  Improved precision of dimensions and shapes of castings.

 

l  Reduced costs of machining operations.

 

l  Simplify pouring systems and increase utilization ratio of mold.

Note: Special size and 10-20 pore size (PPI) can be custom made.

 

 

 

Selection

1) Pore size is based on casting material and casting weight, regularly 10ppi and 20ppi for steel casting filtration.

2) Filter size is decided by the sculpt, fusion and the characteristic of ceramic foam filter.

Package

The filters are packed in carboard box and pallet protecting them from damage.

Box size: 54x36x28cm.

Pallet size: 1.1x1.1x1.9m.

36 boxes per pallet, 10 pallet per 20’’ container, 20 pallets per 40’’container.

Notice of Application

1. In order to reduce the impact of hot molten metal to filters, pouring bowl shall put down as low as possible from filters.

2. It is recommended to use compressed air to blow dust off from filter before usage.

3. Ceramic foam filters should be stored in dry place to avoid moisture.

Q:Ceramic filter capacity.
60 square meters of ceramic filter power 35kW or so, a high degree of automation, each class can complete the operation.
Q:Does the ceramic factory use hydrochloric acid?
For the use of a long time, the method 1, the effect is still no significant improvement, that is how to plug the ceramic filter plate regeneration? The ceramic filter plate with uneven or non sucking slurry can be removed, and oxalic acid or other acid liquid with certain concentration and certain temperature can be taken together to dredge the microporous of the ceramic filter plate. (do not recommend sulphuric acid)
Q:Principle of chemical engineering drum vacuum filter, the faster the speed, the less the amount of filtrate obtained per turn, the more the amount of filtrate obtained per unit time?
The faster the speed is, the shorter the time required for each turn, i.e., the shorter the filtration time, the less the filtrate will be
Q:Beneficiation ceramic filter no problem, the technical parameters are normal, but filter out the concentrate water suddenly excessive, what is the reason?
Beneficiation of ceramic filter, the technical parameters are normal, but the water will fill in groove is what reason
Q:What are the functions of honeycomb ceramic filters?
At present, it is widely used in metallurgy, foundry industry, metal melt filtration, using mullite (cordierite) ceramic materials
Q:How to determine the quality of ceramic fiber filter board simply?
Ceramic fiber filter board, in fact, ceramic fiber board, also known as aluminum silicate, refractory fiberboard.
Q:What happens when the pressure on the filter plate is uneven during backwashing?
It should be said that the ceramic filter backwash, usually with a certain pressure of clean water to backwash.
Q:Working principle, ultrasonic trouble and troubleshooting of ceramic filter
Ceramic filter is mainly composed of system, roller system, mixing discharge system, vacuum system, liquid discharge system, scraper system, washing system, cleaning system, automatic control system, and these parts body frame.
Q:What is the reason that the whole ceramic filter does 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.
Q:Ceramic filter fineness thin mud suction is not what to do more
Users such as pulp size is too small, too much mud, after analysis, the following methods of testing, the results have improved, it may wish to try the following methods, perhaps of help:The vacuum degree is about -0.08MPa.Adjust spindle speed and increase drying time.Ceramic filter plate with suitable pore size range.Ceramic filter plate brand on the market range, its quality is good or bad, the feed condition itself is not an ideal situation, such as ceramic filter plate with the aperture to the mine conditions do not match, it will exacerbate the effects of poor, life is short.It can shorten the combined cleaning cycle, strengthen the cleaning effect and prolong the cleaning time.
