SiliconSlag

Silicon slag is a by-product of metal silicon smelting. It is a mixture of silicon liquid and suspended oxidized impurities formed in the smelting process. After slagging, cooling, selection and crushing, we get standard size silicon slag lumps (10-50mm 90%). The silicon content is between 60% and 85%.

Both size and packing can be customized as clients' requests.

1. Silicon slag is widely used as a deoxidizer and warming agent in steel making industry. It can partially replace ferrosilicon and further help steel plant reduce costs.

2.Used for steel slag recycling of pig iron, general casting, etc.. Silicon slag can improve the furnace temperature, increase the fluidity of molten iron, high-quality slag discharge, increase the label, and update the toughness and cutting ability of iterative casting.

1. First-Hand Experience
As a specialized silicon slag manufacturer, we worked with a Southeast Asian ferroalloy processor facing a common yet costly challenge: high production expenses and inconsistent silicon recovery rates from primary silicon metal. Their goal was to reduce input costs without compromising the final product's silicon content. After evaluating their smelting process, we recommended integrating our Silicon Slag (Si: 50-70%) as a supplementary raw material in specific production stages. The result was a 15% reduction in raw material costs while maintaining targeted silicon yield. From this, we learned that silicon slag is not a waste by-product but a strategic, cost-efficient alternative that can optimize resource utilization without sacrificing quality.

2. Details & Scenario Enhancement
During implementation, the client was initially concerned about impurity levels and potential slagging issues affecting furnace efficiency. We provided not only batch-specific chemical composition reports but also technical guidance on blending ratios and charging intervals tailored to their furnace parameters. Through real-time monitoring and minor operational adjustments, we helped them achieve smoother furnace performance and reduced flux consumption. This hands-on collaboration reinforced that our role goes beyond supply-we act as technical partners, ensuring seamless integration and risk mitigation through data-driven support and process optimization.

3. Real Client Reference
A notable example is our ongoing partnership with "A Metals Group" (a ferroalloy producer in Vietnam). The client struggled with volatile silicon metal prices and occasional supply shortages, which disrupted production planning and squeezed profit margins. Our solution involved a structured transition plan, replacing 30% of their primary silicon metal with our high-grade silicon slag in controlled stages, supported by regular quality audits and performance tracking. The outcome exceeded expectations: within four months, Delta Metals achieved a 12% overall cost saving on silicon inputs, improved furnace stability, and reduced dependency on high-priced virgin silicon metal. This not only strengthened our long-term supplier relationship but also enhanced their competitiveness in the regional silicon alloy market.
