Document Type and Number:
Japanese Patent JP6818686
Kind Code:
B2
Abstract:
The invention relates to a sintering furnace for components made of a sintered material, in particular for dental components, comprising a furnace chamber having a chamber volume (VK) and a chamber inner surface (OK), wherein a heat-up device, a receiving space having a gross volume (VB) located in the chamber volume (VK) and delimited by the heat-up device, and a useful region having a useful volume (VN) located in the gross volume (VB), are disposed in the furnace chamber. The furnace chamber has an outer wall consisting of a plurality of walls having a wall portion to be opened for introduction into the receiving space of a component to be sintered and having an object volume (VO). In the furnace chamber the heat-up device has a thermal radiator having a radiation field which radiator is disposed on at least one side of the receiving space. Said thermal radiator has a specific resistance of 0.1 Ωmm2/m to 1,000,000 Ωmm2/m and has a total surface, the maximum of which is three times the chamber inner surface (OK). With this sintering furnace a heat-up temperature of at least 1100° C. can be achieved within 5 minutes at a maximum power input of 1.5 kW.
