A method of producing bimetallic castings by method of consumable patterns includes producing a cellular polystyrene pattern, producing two channels, connection, dyeing, moulding and filling with liquid fusions. A foundry mould is equipped with a signalling device of level of liquid fusion of the first layer with an angle of its inclination set within the limits of 30±5°, and a coating, permeable for oxygen, is supplied on the hardened surface of the first layer of fusion within the temperature range, which is by 250±20° lower than its solidus temperature. |
