| 摘要 |
This invention relates to a method of producing a lost mold for titanium casting from a curable embedding compound, which contains at least one oxidizable ingredient, in particular zirconium. At least the following method steps are executed: a) shaping of the original mold by embedding a model made of a material that can be melted out in the embedding compound; b) curing the embedding compound and melting out the model material by heating and then cooling the mold according to a predetermined temperature-time profile in a firing furnace. To obtain a mold having improved properties, the mold may be cured under a protective gas atmosphere or with a decreased gas density, in particular under a reduced pressure or in a vacuum. As an alternative, the mold may also be cooled actively after reaching and holding a maximum temperature, in order to thereby shorten the cooling time.
