Abstract (en)

[origin: EP0648559A1] The invention relates to an apparatus for the production of a casting piece (casting) by lost-pattern casting, including a pattern (1) and a sprue (downgate) (7) made from alveolar pyrolysable material, which are embedded in the compacted sand (5), the said pouring descender being connected to a pouring bush (sleeve, cup) made from refractory material (8). The pattern and the pouring descender are lined with a coating of refractory particles, the coating being, at least locally reinforced by means of an inorganic binder. The invention also relates to a method for the production of a casting using such device. <IMAGE>
