Silicon Slag

Grades	:	silicon slag 35/40/45/50/55/60/65/70
Size	:	various sizes available

Silicon Slag is a by-product of silicon metal production. It's the separated part which are less purity of silicon metal. Usually silicon slag contains higher contents of Fe, Al, Ca and other oxide. Silicon, with other elements like Fe, Al, Ca, have strong reaction with oxygen; Meanwhile other impurities are oxide also are not harmful to liquid steel. Those characters made silicon slag to be a great de-oxidizer; It can be used for raising the temperature of liquid steel in steelmaking.

Silicon Carbon Alloy 6515/6818

Grades	:	silicon carbide alloy 6515/6818
Size	:	various sizes available

Silicon-carbon alloy is a new type of alloy used in converters, and can also be called high-carbon silicon.
It can replace ferrosilicon, silicon carbide, recarburizer, reduce the amount of deoxidizer, and be used in converter smelting deoxidation alloying process with stable effect. The chemical composition, mechanical properties and internal control quality of steel are superior to traditional processes.

• Deoxidizing in Steelmaking & Casting
• Improves the quality of molten steel.
• Increases furnace temperature
• Improves slag collection
• Reduces the amount of alloy added.
• Reduces steelmaking costs
