Magnesium Mg is located in the periodic table in the third week ⅡA family, nuclear electron number 12, there are two outermost electrons, easy to lose magnesium participate in the reaction when two electrons to form Mg2 + ions. Metal and chemical activity stronger than aluminum, magnesium, iron and a few other metal outside with most other metal alloys to produce different properties of magnesium-based alloys. Currently Magnesium is used in aerospace, defense, automotive, electronics, home appliances, metallurgy, chemical and other industries.
Production methods are mainly electrolysis of magnesium and silicon calorimetry ( Pidgeon ), in most of our production process using Pidgeon magnesium metal.
Feasibility of Calcium Carbide as a reducing agent:
Ferrosilicon reducing existing problems, many domestic and foreign enterprises, research institutes and universities to replace ferrosilicon reductant, done a lot of research, has published many research results. Chemical properties of calcium than magnesium metal and lively, but many prices higher than magnesium, calcium metal, calcium metal used as a reducing agent from the cost of production in terms of corporate unacceptable. Metal compounds such as calcium: CaO, CaF2, CaC2, CaS, CaCl, the price is relatively low. Through the curve △GT of MgO curve analysis and calculation of the above compounds, and the possibility of taking into account the actual production, excluding the compounds CaO, CaF2, CaCl , etc., are most likely CaC2 carbide and calcium sulfide CaS. Calcium Carbide and calcium sulfide ratio, calcium sulfide prices much higher than the metal magnesium, and Calcium Carbide prices are low, and easy to obtain, our carbide ( Calcium Carbide ) businesses more production is also big.
Magnesium smelting reducing agent for the metal carbide, in theory, the reduction temperature can be reduced more than 100 ℃, increase the reaction rate and yield, shorter reduction time of the reducing agent is lower than the cost of ferrosilicon 75 #, But the disadvantage is that the amount of reducing agent than 75 # ferrosilicon and more, and each tank of magnesium less 7.2Kg, In addition,Calcium Carbide stability worse than ferrosilicon, requiring producers to be especially dry climate location, otherwise, calcium carbide easy to absorb moisture in the air, decomposition of acetylene fire, explosion, process operating on more complex than ferrosilicon. But taken together, compare their effectiveness is greater than ferrosilicon reductant. Therefore, it is worth further testing in actual production , and gradually expand the applications.
