The present invention relates to an arrangement for low-pressure casting of refractory metals, with a furnace chamber with one or a plurality of gas supply openings () and gas outlet openings (), and a riser pipe () through a cover () of the furnace chamber, a melting container () for the refractory metals arranged in the furnace chamber, and a heating device for heating the refractory metals in the melting container (). In the proposed arrangement, the melting container () is formed as an exchangeable insert for a receiving mould () supporting the melting container (), which is arranged in the furnace chamber, wherein a thermally insulating layer () is formed between the receiving mould () and the melting container (), or is integrated into the melting container (). With the proposed arrangement, a quick and easy exchange of the melting container for different alloys can also be carried out in the low-pressure casting of refractory metals.
