Title:
MAGNETIC FIELD FORMING DEVICE, FERRITE MAGNET PRODUCING METHOD, AND MOLD
Document Type and Number:
WIPO Patent Application WO/2005/096331
Kind Code:
A1
Abstract:
An object is to provide a magnetic field forming device, a ferrite magnet producing method, etc, which are capable of improving yield in the production process and stabilizing quality. In forming a magnetic field, a mortar (19) having a plurality of cavities (13) is heated to a predetermined temperature under the control of a controller (23) by a heater member (20). As for the heating temperature, it is preferable that the controller (23) control the temperature such that the temperature (T1) of the mortar (19) detected by a sensor (22) is 40 °C or above. Heating the mortar (19) in this manner can raise temperature of molding-purpose slurry in the cavities (13), thereby improving dehydratability and yield of products.
