Ryobi Group Ceramic Foam Filter is suitable for purification and filtration of high-temperature aluminum and aluminum alloy solutions. It can filter non-metallic slag and slag as small as micrometers, making the surface of castings smoother and reducing processing losses.
Filtration can make the molten aluminum fill the cavity more uniformly. The molten metal has a higher tendency of turbulence during the casting process, and finally is transformed into a very stable laminar flow through the turbulent flow of the three-dimensional pore structure. Laminar flow has a better effect on the cavity. The filling, thereby reducing the metal solution pair.
Impact corrosion of the casting cavity, significantly reduce the rejection rate, reduce production costs, and improve labor productivity.
Ryobi Group Ceramic Foam Filter-These filters are only used for aluminum castings.
Currently, the market’s leading suppliers offer various sizes and thicknesses.

This helps to seal the filter in the filter box to ensure that there is no side flow of molten metal.
Metal casting filter can effectively remove various inclusions in the aluminum water with a fineness of micrometers. The molten aluminum becomes a smooth laminar flow, which is conducive to flushing. It has good mechanical strength and chemical stability, and excellent resistance to aluminum washout. Strictly controlled hole size and through-hole rate can obtain a stable filtering effect.
When using a ceramic foam filter, the pore size of the filter should be determined according to the quality requirements of the casting and the number of inclusions in the molten metal. According to the pouring speed and pouring weight to determine the size of the filter.
In order to ensure the filtering effect of the filter, the placement of the filter, and the design of the gating system should also follow certain... less

The double rotor degassing unit uses a new type of high silica lining, located between the furnace and the casting machine, and mainly removes hydrogen and other residues in the molten aluminum.
After being purified by the AdTech degassing unit and CFF filter box, the aluminum liquid can be used for the production of high-precision products such as computer hard disks, photoconductor drums of photocopiers, aluminum foil, PS plate base, and turbine engine fan blades.
Double Rotor Degassing Unit Working Principle
Hydrogen is absorbed into the bubble and is eliminated;
Alkali metals are eliminated by chemical interaction with chlorine gas (formation of chloride);
The inclusions are trapped by bubbles and then rise to the surface of the melt to form dross.
Precautions for use degassing unit

The solid inclusions suspended in the aluminum liquid will also be adsorbed on the surface of the bubbles and be removed together.
After online purification treatment for molten aluminum, the hydrogen content of molten aluminum can be reduced to half of the original value. Non-metallic inclusions with a particle diameter below 50μm can be removed by 50%, and those above 100pm can be removed by 90%. Adding Cl2 in the inert gas can increase the hydrogen removal rate from 50% to 65%, and also remove 60%-75% of Na and Li. This is useful for the production of aluminum-magnesium alloys and the direct extraction of molten aluminum from the electrolytic cell to produce aluminum Material is very important.

THE LAB determined 10 kW, 50-150 kHz induction heating system with a four turn, two-over-two helical coil would be optimal for this induction shrink fitting application. The frequency for this application was 132 kHz.
Initial testing was conducted to optimize the power delivered to the part. System power was applied for 14 seconds to reach the target temperature of 1000 ºF (538 ºC). The carbon graphite rings was then inserted and the assembly was allowed to cool which created a strong joint between the two pieces. This achieved the client's time and quality objectives.
For this shrink fitting application, induction heating offered several advantages. It delivered rapid heating which saved power and time. It's also a clean source of heat. Induction delivers less heat into the work environment than a torch and takes up less space than an... less

As we’ve explored in an earlier blog, degassing is used to reduce the risk of gas porosity in aluminium sand casting. Porosity can occur when hydrogen is introduced into the metal during the melting stage. This can be drawn in through atmospheric humidity or moisture in the foundry.
In degassing, the molten metal is purged with nitrogen gas before the pouring stage. The nitrogen gas reacts with any hydrogen before dissipating from the molten metal.
Fast, effective degassing
At Haworth Castings, we use a hand-held rotary degasser – which has a rotating shaft and rotor at the base of a long narrow pole with handles. This unit is attached, through a tube, to a nitrogen canister.
The degassing unit is placed in the molten metal and, once operational, a high volume of bubbles is generated across a large surface area. This leads to the fast diffusion of hydrogen into the gas bubbles.... less

It can effectively filter non-metallic inclusions in molten aluminum once or twice, thereby reducing slag holes, improving the mechanical properties of castings, and reducing processing allowances.After the aluminum alloy material is mixed with slag, the performance of the alloy deep-processed parts will be destroyed, and the yield will be reduced, which will cause a certain economic loss.In production, it is required to adopt the method of slag removal and filtration to eliminate the slag inclusion as much as possible.Slag inclusions in aluminum alloy castings are one of the main factors affecting the quality of deep-processed products.The quality of the product directly affects its market share and economic benefits.In order to survive and develop, it is necessary to increase the added value of products and carry out deep processing.There are many reasons for molten... less

Excessive quantities of this dissolved gas have a well-documented detrimental effect on the mechanical properties of the final aluminum castings. What is also well known to anyone making castings is that dissolved gas has an overriding effect on the distribution and amount of porosity and shrinkage. Dissolved hydrogen levels must be controlled to minimize scrap. To control gas in aluminum, metalcasters must accomplish two things:
1. Prevent and minimize introduction of hydrogen in the melt.2. Measure and remove the hydrogen prior to pouring.This article will focus on measurement and removal.Gas Removal
The ability to degas molten aluminum is generally accomplished by using a purge gas, typically introduced into the melt by a rotary degassing unit. This degassing process is limited by thermodynamic laws; when purge gas bubbles are introduced to the melt,... less

Aluminum foil is widely used in food packaging, cigarette paper, cosmetics and other industries, but the production process is extremely complicated.
Romania ceramic foam filters can reduce the turbulence of molten aluminum and carry out rectification and purification of molten aluminum.
The filtered and purified aluminum castings can significantly extend the service life of parts with high demand such as aviation and auto parts, and also have good effects on aluminum and copper parts that require surface polishing.
Ceramic foam filter also plays an important role in the traditional aluminum industry, electrical aluminum industry and continuous casting and rolling processes.
