Definitions
- the invention relates to various processes for the production of lost molds for titanium casting.
- Workpieces made of cast titanium are increasingly used in technology due to the excellent material properties and the relatively low price of titanium.
- titanium is also increasingly used in the field of dental technology applications.
- the zirconium is said to keep oxygen away from the titanium melt.
- this effect is only insufficiently achieved since the zirconium is contaminated with oxygen as soon as the mold is fired.
- the casting object is first modeled and fastened to a casting funnel former in a muffle ring or the like by means of casting channels made of a suitable material, for example wax.
- the investment material is then mixed with a prescribed amount of mixing liquid, for example water, and poured into the muffle, the cast object being completely enclosed and the desired shape thereby negatively reflected in the investment material.
- the muffle with the cast funnel former is pressurized in a pressure pot in order to further compact the investment.
- the investment is cured for at least 30 minutes at room temperature and then the casting funnel former is removed.
- the muffle is then placed in a cold furnace and the furnace is heated up to a temperature of 850 ° C at a rate of at least 7 ° C per minute.
