Calcium and silicon have a strong affinity with oxygen. Especially calcium metal has a strong affinity with oxygen and has a strong affinity with sulfur and nitrogen. Therefore, calcium silicon is an ideal composite deoxidizer and desulfurizer. Silicon alloys have a strong deoxidizing ability, which helps the deoxidized products easily float and discharge, but can also improve steel’s performance in the plasticity, impact toughness, and fluidity，ductility. At present, calcium silicon alloy can replace aluminum for final deoxidation.
According to a number of national standard silicon calcium factories reflect, the recent shipment of silicon calcium is slightly better than the previous period, some manufacturers inventory began to show a downward trend.
According to the person in charge of the enterprise analysis, one is the May Day holiday is approaching, some enterprises may have a stock plan; Second, the previous downstream inventory consumption, start a new round of procurement; Third, early magnesium ingot price surge or downstream mentality to stimulate. Although the shipment of silicon calcium is slightly improved, there is no obvious fluctuation in price. The quotation and transaction of the factory remain stable. It is expected that the market price of silicon calcium will not change much in the early May Day.
According to the mainstream transaction report of silicon calcium alloy this week, the mainstream transaction price of national standard ca1 market in Shaanxi is 11800-12000 yuan/ton, the market transaction price of Ningxia is 11800-12000 yuan/ton, and the market transaction price of Inner Mongolia is 11600-11800 yuan/ton. The GB ca2 market trading price in Shaanxi is 11600-11800 yuan/ton, the market trading price in Ningxia is 11600-11800 yuan/ton, and the market trading price in Inner Mongolia is 11400-11600 yuan/ton. The transactions of ca28si55 and ca28si50 in Henan were 11400-11600 yuan/ton and 10,400-10,700 yuan/ton.
International market prices
According to the export market transaction report data this week, the current GB ca1 export transaction price is 1750-1850 USD/ton, GB ca2 1730-1830 USD/ton (FOB, Tianjin Port), this week the export price of silicon and calcium is temporarily stable.
In April 2023, there were a total of 5 enterprises in the silicon calcium market with a total of 5 actual furnaces. The operating rate of the enterprises was about 50%, and the operating rate of the number of furnaces was about 66.67%, the same as last month. The total market output is expected to be about 6200 tons in April, an increase of about 650 tons compared with the actual output of March (5550t).
The future market forecast of silicon calcium alloy
In the middle period, Ningxia Zhongwei national standard silicon and calcium enterprises resumed production, and the market operating rate increased. According to the recent statistics of 6 national standard silicon and calcium alloy manufacturers, there were 5 silicon and calcium enterprises in the market in April, and the actual number of furnaces was 6. The operating rate of enterprises was about 83.33%, and the operating rate of furnaces was about 60%. Third, the surge in the price of magnesium ingot in the first ten days stimulated the downstream mentality. The current overall demand is still in a weak state, but there is cost support, silicon calcium factory to yield profit shipment is not high, so it is expected that the early May Day silicon calcium alloy price will continue to deadlock and stable operation.
