About calcium silicon
Calcium silicon is a binary alloy composed of silicon and calcium. Its main components include silicon and calcium, in addition to containing different amounts of aluminum, carbon, sulfur, phosphorus, iron and other impurities. Calcium silicon is often used as a deoxidizer, desulfurizer, calcium additive and denaturant for non-metallic inclusions in the iron and steel industry. Calcium silicon is commenly used as an inoculant and denaturant in the cast iron industry.
The role of silicon calcium
Calcium silicon has a wide range of uses. Adding calcium silicon to molten steel can produce a strong exothermic effect, which is conducive to maintaining the temperature of molten steel. Calcium vapor has a stirring effect on molten steel, which is beneficial to the floating of non-metallic slag.
In the process of casting iron, calcium silicon can effectively improve the properties of iron. It is not only an effective inoculant to promote the formation of spherical graphite, but also has the functions of desulfurization, deoxidation, silicon increase, and denitrification. Calcium silicon granules can be made into CaSi alloy cored wire.
Recent silicon calcium prices
This week’s export price of calcium silicon in China: ca30si60 1850-1950 US dollars; ca28si58 1830-1930 US dollars. At present, the bidding period is empty, and the inquiry and procurement atmosphere in the silicon-calcium market is slack, and most of the transactions are based on just-needed orders. As far as the recent actual transaction situation is concerned, the transaction price of calcium silicon is basically the same as last week.
According to the person in charge of the silicon-calcium factory in Inner Mongolia, their current inventory of silicon-calcium has been exhausted, and there may be a plan to resume production in the near future, but the specific time is to be determined. At that time, the pressure of market competition will increase again, and it is not ruled out that the price may continue to be lowered. Regarding the trend of the silicon-calcium market in the first half of the year, the industry is mostly pessimistic. Without the support of actual demand, it is difficult to boost the silicon-calcium market.
Calcium silicon alloy outlook forecast
This week, the silicon-calcium market operated weakly and steadily, with little change in factory quotations and transaction prices. The consumption of terminal enterprises has not yet increased, and the transaction status of the silicon-calcium alloy market is not good. Some companies have good expectations for March, saying that they may implement a production resumption plan before the end of this month. There are also companies in areas where electricity prices are high and costs are higher than in other production areas, and they are hesitant about whether to continue production. In the later stage of the calcium silicon market, the focus will be on the changes at the start of work.
