CaO-CaF2渣系焊条气渣反应中固体微粒沉淀规律

用抽取法测定了电弧气氛固体微粒 ,分析了CaO—CaF2 渣系电弧气氛中固体微粒含量与药皮成分之间的关系 ,结果表明 ,无论是气相中的熔渣冶金产物NaF的蒸发量 ,还是无明显冶金反应的药皮组成物SiO2 、MnO自身的蒸发量 ,都与药皮组成物有密切的关系 ,并经非线性及线性回归建立了数学模型。NaF与 (萤石 )的n次方成正比 ,其中比例系数与大理石含量呈直线关系降低 ,SiO2 、MnO的蒸发量与其在药皮中的含量呈直线关系增加

Depositing Regularity of Solid Particles During the Gas and Slag Reaction for CaO-CaF2 Slag System Electrode

The relationship between the amount of the solid particles in arc atmosphere and the coat composite was analyzed by using welding fume drawing method. The results show that both the vaporized amount of NsF in gas phase ,the product of metallurgical reaction in molten slag ,and that of SiO 2 MnO in coat joining less metallurgical reaction are closely related to the coat composite content. Meanwhile a numerical model was built through non-linear and linear regression. The amount of NaF is proportional to the n power of fluorite content ,and the constant coefficient is proportionally decreased with increase of the marble content, and that of SiO 2 MnO is proportionally increased with increase of the marble content.
