We are a leading supplier of high quality ferro alloy materials like calcium silicon and iron deoxidizer to industrial steel making. We supply to South Asia, Middle East and South America.
RIMA’s production process is carbon neutral. It captures CO2 from the atmosphere and regenerates O2. The energy source is renewable biomass.
The alloy is primarily composed of silicon and calcium, and also contains iron, aluminum, carbon, sulfur, and phosphorus. It is used as a deoxidizer and desulphurizer for steel-making and cast iron.
The affinity of silicon and calcium with oxygen makes them an ideal compound deoxidizer and desulphuriser. These properties also prevent slag formation during deoxidation, thereby significantly improving the liquid steel's plasticity, impact toughness and fluidity.
This is a cost-effective alternative to traditional bulk alloy inoculants, as it does not need any heating and can be fed into the molten metal directly. Additionally, it does not need to be reclaimed, as it can be reused in the casting process. RIMA's production process uses charcoal (renewable source) and wood chips (from its own forestry units, ensuring that CO2 is fixed) as inputs for the calcination reaction, resulting in an environmentally friendly product.
During the steel making process, calcium silicon alloy acts as an ideal composite deoxidizer and desulfurizer. It helps to eliminate the non-metallic inclusions and improve the quality of steel. It is also used as an inoculant for casting iron.
It improves the graphite distribution uniformity and spheroidal shape in cast iron. It also reduces the chilling tendency and makes it easier to float out. It can be easily added to the molten metal and is very effective in preventing alumina inclusions clogging at the tundish valve in continuous casting operations.
RIMA produces its calcium silicon alloy using charcoal and wood chips from renewable sources rather than mineral coal (fossil fuel). This not only saves electricity costs but also reduces CO2 emissions. This is the main reason why RIMA’s products have superior performance compared to others on the market.
Manganese is a metal that is often used to improve the strength and hardness of iron materials. It can also help to improve their ductility, which is their ability to deform without breaking. Manganese also has a number of other benefits, including its ability to reduce corrosion and protect against oxidation.
Manganese can be found naturally in the earth's crust, making it a relatively common metal. It is a brittle metal in its pure form, but it can be alloyed with other metals to increase their strength and durability.
Manganese is produced from pyrolusite, rhodonite, braunite and hausmannite through smelting processes. It is a key ingredient in steel-making and cast iron production, as it acts as a deoxidizer to prevent oxygen from entering the steel melt.
Alloys that contain phosphorus are very useful in steelmaking. These compounds are effective deoxidizers, desulfurizers and also help control the shape, size and distribution of oxide and sulphide inclusions in the steel. This results in improved fluidity, processability and ductility of the steel product.
Phosphorus added to molten alloys containing more than the eutectic concentration of silicon has a very significant effect on the form and distribution of the primary silicon phase. It has been found that retained trace concentrations ranging from 0.0015 through 0.03% P are effective in achieving the desired modification structure.
Distributor of ferroalloys including calcium silicon, ferrochrome, manganese and ferrovanadium in forms such as lump, granular, powder and micron sized. Packaging options include pails, paper bags and fiber drums; FIBC bulk bags offered as well.
Vanadium is a minor component of the titanium-aluminum-vanadium (TiAlV) alloy currently used in cementless hip prostheses. The present study aims to verify the correlation between the matrix and the level of vanadium in serum, urine and whole blood samples from 129 patients implanted with TiAlV-alloy implants.
The results of mechanical testing showed that the addition of vanadium to ductile iron improved the tensile strength of the material. The results indicated that the vanadium-alloyed materials had consistently higher tensile values than pure iron powder even when nitrogen was not added to the sintering atmosphere. The impact strength of the materials was lower than that of the pure iron powder but showed a small improvement when nitrogen was introduced to the sintering atmosphere. Measurement of the ferrite grain size found that the vanadium-alloyed powders had a finer granular structure.
