Heat treatment method e.g. for dental casts and fillings

摘要

The figure shows the duplicating equipment (10) with a cylindrical reservoir or supply (11) open at the top and with, in the floor region, an opening (12) closed by a tap, enclosed in a housing (13). The opening or outlet projects partly from the housing and, under it, there is, outside the housing, a drain channel (14). The upper part of the housing is closed by a cover (15) and the housing is insulated against heat loss. The reservoir or container (11) is equipped with several heating units, in the case illustrated, the heating rings (16, 17, 18, 19) encircling the container at uniform distances apart, electrically heated and provided with heat sensors. They can be heated individually, controlled by thyristors and a microprocessor.
