Most people think that silicon slag is useless alloy slag. In fact, people in the steelmaking and foundry industry know that some silicon slag is left over from the original silicon ore after refining, and it also contains a lot of silicon. One of the metallurgical materials purchased by manufacturers in large quantities has an irreplaceable advantage. 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. The silicon slag itself has high utilization value and can be recycled or used as a deoxidizer. The following Anyang Shengchi Metallurgy will introduce it in detail:What is silicon slag:
Silicon slag is the residue left after silicon ore is refined, and the residue also contains a lot of silicon content. In addition, silicon slag has a wide range of uses, and silicon slag has different specifications, and of course the uses are also different.What is the purpose of silicon slag?
Silicon slag can also be used for steel slag re-smelting pig iron, ordinary casting, etc. Silicon slag can improve furnace temperature, increase molten iron fluidity, high-quality slag discharge, increase markings, and update toughness and cutting ability of iterative castings. Stainless steel manufacturers use silicon slag as a reducing agent in the process of re-smelting stainless steel with electric furnaces to upgrade efficiency and output.
Silicon slag classification: ferrosilicon slag and silicon metal slagThe silicon content is: 30%-70%;
Trace elements of silicon metal slag:
Fe: 1.5%-2.5%, Al: 3.0%-6.0%, Ca: ≤3.0%, C: ≤8.0%, S: ≤0.1%, P: ≤0.05%;
Ferrosilicon slag: Fe: about 15%Anyang Shengchi Metallurgy can process customized 30-65% silicon slag according to customer requirements;
The silicon slag granularity can be divided into: 0--1mm, 0--3mm, 0-10mm, 1-10mm, 10-30mm, 10-80mm, 10-100mm or customized
Silicon slag packaging: according to customer requirements
