(Summary description)Ferrosilicon is a common additive in steel smelting process.It has a good deoxidizing effect in steel smelting process.This is because ferrosilicon reacts with the oxygen in liquid steel to form silica,which floats on the surface of liquid steel,thus achieving good deoxidizing effect.The choice of ferrosilicon raw materials also has a great impact on the quality of ferrosilicon.In order to deepen our understanding,we follow ferrosilicon manufacturers to see how to choose ferrosilicon raw materials.

Information

Ferrosilicon is a common additive in steel smelting process.It has a good deoxidizing effect in steel smelting process.This is because ferrosilicon reacts with the oxygen in liquid steel to form silica,which floats on the surface of liquid steel,thus achieving good deoxidizing effect.The choice of ferrosilicon raw materials also has a great impact on the quality of ferrosilicon.In order to deepen our understanding,we follow ferrosilicon manufacturers to see how to choose ferrosilicon raw materials.Ferrosilicon is mainly used as deoxidizer and alloy for steelmaking.Phosphorus(P)and sulfur(S)are impurities which have great influence on the quality of steel.Therefore,the phosphorus and sulfur content is very low.Phosphorus exists in silica as phosphorus pentoxide(P2O5),and most of phosphorus pentoxide is reduced into ferrosilicon by carbon during smelting.Therefore,phosphorus pentoxide in silica is required to be no more than 0.02%.Sulfur content in silica,due to the smelting process of sulfur(S)and silicon(Si)formed silicon sulfide,such as SiS,SiS2 and other compounds,these compounds at high temperature volatile away,so silica sulfur content is not required.The content of calcium oxide(CaO)and magnesium oxide(MgO)in silica is relatively high,which will increase the amount of slag and erode the iron mouth during smelting.Therefore,the total content of calcium oxide and magnesium oxide in silica is required to be less than 1%.

The key to the steel price trend is inventory
Since the second quarter of this year,the country's steel prices rise in shock.Lange Steel network market monitoring data shows that as of August 14,2018,Lange steel price composite index is 168.6 points,up 12.4 percent from March 30 this year.The long material price index is 185.1 points,up 19.3%;Plate price index is 153.9 points,up 8.6%.On August 13 this year,the rebar main contract closing ton price was 4,327 yuan,up 27.6%from March 30.

Baosteel said the devaluation of the yuan has increased financial costs and reduced exports to the United States in the second half of the year
Baosteel Corp(600019.SS),China's largest steel producer,said on Tuesday that the depreciation of the exchange rate has caused its financial expenses to rise and the company has increased the lock-in ratio of its foreign currency exposure to current trade frictions with the United States and the devaluation of the renminbi.Company exports are expected to be generally steady in the second half of the year,although exports to the United States will be lower.
