Role of evaporation in the formation of smelting dust

详细

The role of evaporation and dispersion in the formation of smelting dust is considered. A mathematical model is proposed for the evaporative generation of dust when working molten metal. It is compared with experimental data. The main factor affecting the mass of dust formed and the dimension of the dust particles is the surface temperature of the melt. Increase in that temperature increases dust emission, and the particle diameter is greater. The size of the smelting-dust particles is considerably increased on coagulation: at liquid drops or in electrostatic, magnetic, and acoustic fields.
