Premium quality ferro alloys designed to deliver strength, consistency and reliability for every industrial need.
We are a premier manufacturer and global exporter of high-quality ferro alloys, specializing in Silico Manganese & Ferro Manganese. With a robust production capacity of 20,000 metric tons per month, we are dedicated to supplying the essential elements that make modern steel stronger, cleaner, and more durable.
Our state-of-the-art facility is powered by fourteen Submerged Arc Furnaces (SAF), allowing us to maintain continuous, high-volume production without compromising on the precise chemical compositions our clients demand.
We are a globally recognized partner. Currently, approx. 80% of our products are exported to international markets, with the remaining approx. 20% dedicated to domestic and captive consumption. We are particularly proud of our continuous supply of specialized Low Boron Silico Manganese to steelmakers worldwide, a testament to our manufacturing precision.
Strictly controlled to meet international specifications, ensuring optimal deoxidation and alloying for steel manufacturing.
Our flagship product, providing a highly effective combination of silicon and manganese for steel purification and strength.
Delivering high manganese content to improve the tensile strength, workability, and wear resistance of steel.
Carefully processed to meet the rigorous demands of specialized low-carbon steel production.
We utilize a highly controlled Carbothermic Reduction Process to ensure the highest grade of alloy extraction. Our modernized facility allows for seamless material handling from raw ore to final dispatch.
Quality begins at the source. We utilize high and medium-grade manganese ore, combined with premium reductants including coke and coal. Materials are fed into storage bunkers via an automated belt conveyor system.
Precision is managed from our central control room. A programmable logic controller (PLC) system seamlessly regulates the exact ratios of raw materials, dropping batches into the furnace charging hoppers for optimal chemical balance.
The charge is fed into our Submerged Arc Furnaces. Heavy electric currents are passed through three massive carbon electrodes, generating the intense heat required to reduce the manganese ore into molten alloy and slag.
After reaching target power consumption, tapping is initiated by opening the tap hole via oxygen lancing. The liquid metal and slag flow through a sophisticated runner and skimmer system. The lighter slag is diverted to a sand bed, while the pure molten alloy is channeled into casting moulds.
The liquid metal cools in designated metal beds. Once solidified, the metal casts are transferred to the finished yard, where they are crushed and broken into specific lump sizes tailored to individual client order requirements.
Quality is not just a promise; it is a verifiable metric in every batch we produce.
Once sized, the metal is grouped into designated lots and rigorously tested by our internal quality assurance team.
Before any material leaves our facility, an independent third party takes samples and conducts powder testing in their own laboratories to guarantee unbiased certification.
Once approved, the finished ferro alloys are securely packed into heavy-duty Jumbo Bags. Our streamlined dispatch operations ensure that our monthly exports reach global ports safely, efficiently, and exactly to spec.
Whether you need standard SiMn 65/16 or specialized low-boron formulations, our team is ready to meet your exact specifications.
