Inventor: TASAKA YURIYASU
IPC: C21D9/00
Filed: 1989-04-24
Abstract: PURPOSE:To prevent the development of decarbonized layer and to obtain a steel slab having the extremely thin surface decarbonized layer in as-roll product by regulating heating time at temp. exceeding A1 transformation point temp. in a walking beam type heating furnace and heating the steel slab. CONSTITUTION:At the time of heating the steel slab in the walking beam type heating furnace, the heating time at the temp. exceeding the A1 transformation point temp., where diffusion phenomenon of C becomes active, is made <=30min. The regulation of the above heating time can be achieved by shortening time in the furnace and heating uniformly, or by suppressing the heating temp. in the heating zone to low and making heating temp. in the soaking zone high to execute rapid heating, etc. By this regulation, the diffusion of C is suppressed to prevent the development of the surface decarbonized layer. By this method, removal of the decarbonized layer in the product after heat treatment is unnecessary and can be used in as-roll.

Title: Method for controlling floating melting zone of semiconductor rod
Inventor: IKEDA YASUHIRO
IPC: C30B13/28
Filed: 1987-04-27
Abstract: PURPOSE:To enable control of the zone length and diameter of a formed crystal with quick responsiveness and stability, by regulating moving speed of a semiconductor rod on the melting out side, controlling the length of a melting zone in the axial direction and regulating electric power supplied to a heater. CONSTITUTION:The lowering speed (Vp) of a semiconductor rod (upper rod) is kept at a constant value and supply electric power (P) is increased stepwise to temporarily increase the diameter (Dsi) of a formed crystal. The zone length (L) is then delayingly increased to subsequently reduce the diameter (Dsi) of the formed crystal and almost equal to the original value. That is the Dsi is not changed simply by increasing the supply electric power (P). On the other hand, if the supply electric power is kept at a constant value and the lowering speed of the upper rod is increased stepwise, the zone length (L) is relatively rapidly reduced to simultaneously increase the diameter (Dsi) of the formed crystal. The diameter (Dsi) of the formed crystal is controlled by the supply electric power (P) and the zone length (L) is controlled by the lowering speed (Vp) of the upper rod. Thereby effective diameter control can be carried out.
