Ground lime powder offer in understanding the concept of lime, lime is used to reflect the physical nature of the content: the color of lime, crystal structure, organization, smell, porosity, bulk density, specific gravity, bulk density, melting point, boiling point, thermal conductivity , specific heat, light, resistance, hardness, expansion coefficient, refractive index, angle of repose and the like. Lime: high ground in terms of BOF lime powder, lime size requirements for active ground lime powder prices, is to ensure that the requirements of steel-making process at the time of slagging speed and effectiveness. If the lime particle size is too large, the reaction time will lead to lime particles and molten steel is lengthened, so slow down and affect slagging slagging effect. Conversely, if the particle size is too small lime, at the time of steelmaking dust particles or splashes easily cause deteriorated operating environment.
