Using the best available technology (BAT), the Ferrochrome SAF furnace designed and manufactured by Sanrui adopts advanced tubular water-cooled furnace cover technology, tubular water-cooled furnace wall technology, copper-steel composite plate conductive cross arm technology, EBT steel-tapping technology, large-section water-cooled cable technology, PLC control technology, high impedance technology, auxiliary energy technologies such as carbon-oxygen gun oxygen burner, oxygen-enriched operation technology and hot iron charging technology, etc.

We provide a series of ferrosilicon furnace cover designs to suit different ferrosilicon furnace applications. The closed furnace cover solution makes smelting and maintenance safer. The furnace cover is usually made of water-cooled steel plate, but a combined solution combining water-cooled steel plate and refractory materials can also be used. The airtight seal ensures low emissions and efficient collection and utilization of CO gas.

Minimizes consumption of energy, coke and electrode paste

Achieves high productivity and metal recovery, especially when using pellets

Purified CO gas can be used effectively in different plant applications

Preheating to 600ºC saves 70 kWh per ton of metal smelted for every 100ºC increase in temperature

Allows you to reduce operating costs and reduce CO₂ and dust emissions
