现在,用熔剂法在РКЗ—16.5和РПЗ—48(63)型电炉中生产硅锰要往炉料中配加硅石和白云石(石灰石)。由于用炭从含二氧化硅很高的复合氧化物(硅锰炉渣)中同时还元锰和硅的热力学和动力学的特殊性,这种方法的特点是炉料还元受到限制。强化硅锰生产过程的途径之一就是在炉料组分中用碱金属氧化物代替碱土金属氧化物。碱金属氧化物可加速还元过程,促使降低酸性炉渣的粘度和稳定电气制度。事实证明,必须把这种氧化物以化合物形式,特别是以最广泛采用的铝硅酸盐形式[(Na_2O+
Silica and dolomite (limestone) are now added to the charge by the flux method for the production of silicomanganese in the РКЗ-16.5 and РПЗ-48 (63) electric furnaces. Due to the particularity of the thermodynamics and kinetics of simultaneous oxidation of metamanganese and silicon from carbon dioxide-rich composite oxides (silicomanganese slag), this method is characterized by a reduction in charge. One of the ways to strengthen the production of silicomanganese is to replace alkali earth oxides with alkali oxides in the charge composition. Alkali metal oxides accelerate the restitution process, leading to lower viscosity and stable electrical regimes of acidic sludges. It has turned out that this oxide must be present as a compound, in particular in the form of the most widely used aluminosilicate [(Na 2 O +
