1. Method for heat treatment of metal products in a fluidised- bed furnace, consisting in heating the granular gas-fluidised bed to the operating temperature, locating metal products in the bed and subjecting them to heat and gas treatment, consisting in that the bed in the operating chamber (1) of the fluidised furnace is fluidised with air fed through a grill (2), and then a container (3) with a grill (4) is immersed in the bed, whereas a controlled atmosphere is fed through that container, and than metal products (5) are placed in the container (3) and subjected to treatment at temperature of 300-1,300 degrees C for a time length from 1 minute to 20 hours with the controlled atmosphere flow rate ranged the minimum as necessary for fluidisation up to 10-times bigger rate, whereas the bed in the operating chamber is fluidised with air.<IMAGE>
