A process for producing hot metal includes partially reducing granular raw materials containing iron oxide with a carbonaceous reducing agent in a fluidized bed reactor at a temperature of at least 850&#xb0; C. so as to obtain a reduced mixture. The reduced mixture is cooled to between 600&#xb0; C. and 800&#xb0; C. in a heat exchanger apparatus using a preheated process gas as a cooling medium that is preheated to between 300&#xb0; C. and 500&#xb0; C. before being introduced into the heat exchanger apparatus. The reduced mixture is then supplied to a smelting reduction unit via a discharge system.
