摘　　要：通过实验使用表面粗糙度测试仪测定了无氟连铸结晶器保护渣的表面粗糙度,研究了碱度R、Li_2O、TiO_2、Na_2O、B_2O_3、MgO对保护渣表面粗糙度的影响。实验证明:碱度大,Li_2O、TiO_2、Na_2O、MgO含量高的保护渣,其冷态下的表面粗糙度相对较高;保护渣的玻璃化性能随着B_2O_3含量的提高而变好,表面更加光滑;MnO含量在2%~4%时,随着的MnO含量的增加,表面粗糙度变大;MnO含量在4%~6%时,随着的MnO含量的增加,表面粗糙度变小。The surface roughness of mold fluxes for fluorine free continuous casting mould is measured by surface roughness tester. The influence of alkalinity R, Li_2O, TiO_2,, Na_2O, B_2O_3, MgO on the surface roughness of slag is studied. Experiments show that with high basicity, Li_2O, TiO_2, Na_2O, MgO content, the surface roughness of the slag at cold state is relatively high. With increasing B_2O_3 content, the vitrification of slag is better, and the surface is smoother.When the content of MnO is 2%~4%, with the increase of MnO content, surface becomes rough. When the content of MnO is 4%~6%, with the increase of MnO content, the surface roughness is smaller.
