High Quality Silicon Slag Supply

1.Silicon content from 30~50% is used for silicon addition for iron making in the blast furnace and cupola.

2. Silicon content from 50~70% is used for the deoxidization of steel making.

3.It is a good substitute for FeSi in steel making, which has advantage in lowing the cost of production and reusing resource

Cost comparison: Ferrosilicon 7,100 yuan/ton: Carburizing agent 3,000/ton: According to calculations, during the resmelting process, it costs 4,930 yuan to obtain 50% of silicon, and 663 yuan to obtain 21% of carbon. Comprehensive calculations show that , the actual value of element 6 is 5593 yuan, and the current price of element 6 powder is 4500 yuan including tax. To sum up, the foundry can reduce the cost by 1093 yuan for every ton of element 6 powder used; If a foundry uses 100 tons of ferrosilicon a month, and if element 6 powder is used instead of ferrosilicon, then 144 tons of element 6 are used every month, and the monthly cost savings is 157,392 yuan.

Moreover, the use of element No. 6 can also reduce the use of carburizing agents, thereby reducing workers' labor force and improving the production efficiency of enterprises.

Silicon slag, as one of the metallurgical materials purchased in large quantities in steel and foundry plants, has irreplaceable advantages. Most people believe that silicon slag is a waste of useless ferroalloy slag. In fact, many industry insiders know that silicon slag is the residue of the original silicon ore after extraction, and also contains a large amount of silicon. Due to the different uses of silicon, there are many types of silicon slag, which can be roughly divided into industrial silicon slag, solar silicon slag, and semiconductor silicon slag. Silicon slag itself is also very valuable and can be recycled and used as a deoxidizer.

silicon slag can be mainly used as a deoxidizer and refining industrial silicon, and silicon slag as reductant can reduce costs and increase profits. Some silicon slag contains silicon components and can also be used to purify industrial silicon..Due to the low price and silicon content of silicon slag, steel mills tend to use silicon slag products when purchasing ferroalloy raw materials during steelmaking. The desulfurization performance of silicon slag is also good, mainly because silicon slag contains a large amount of alkaline oxides, which can react with sulfur dioxide to generate sulfates. Its slurry can be used for flue gas desulfurization.

Silicon slag is widely used in steel slag re-smelting pig iron and ordinary casting. It can improve the furnace temperature, dilute the molten iron, increase the fluidity of the molten iron, promote slag discharge, and increase the label.

1. Silicon slag can be used for refining, recrystallization and purification;
2. Effectively discharge slag, increase the label, improve the toughness of the casting and the cutting ability, stainless steel manufacturers use silicon slag as a reducing agent in the process of refining stainless steel in an electric furnace to increase the rate and output;

3.Silicon slag can used in steel mill instead of Ferro silicon .
