Abstract (en)

[origin: WO9108655A1] A heat-treatment device equipped with a cylindrical directly powered far-infrared ceramic heater for heating a columnar or cylindrical object to be treated, which is placed concentrically therewith, from the surrounding. This device can uniformly heat-treat an object. This invention also provides a method of drying a coating film of polymeric coating liquid formed on the surface of a columnar or cylindrical substrate using a specified heating pattern using said heat-treatment device. Said drying method prevents the surface of a coating film from being dried earlier than the inner part thereof so that uniform drying may reach even the inner part of the coating film.
