Bi-2212 HTS tube was fabricated by centrifugal forming and partial melting processes. Bi-2212 bulk tube has been optimized to achieve smooth surface and uniform thickness. The slurry was prepared in the mixing ratio of 10:1 between Bi-2212 powder and binder and initially charged into the rotating mold under the speed of 300~450 rpm. Heat-treatment was performed at the temperature ranges of 860~89$0^{circ}C$ in air for partial melting. the HTS tube fabricated by centrifugal forming process at 89$0^{circ}C$ under the rotating speed of 450 rpm was highly densified and the plate-like grains with more than 20${mu}{ extrm}{m}$ were well oriented along the rotating axis. The measured Tc and J$_{c}$ at 10K on specimen heat treated at 89$0^{circ}C$ was around 85 K and 1,200 A/$ extrm{cm}^2$ respectively.y.
