The data of experimental-industrial application of a recuperative water heater for the water heating, which supplied to the pelletizer under the conditions of the sintering machine No. 1 of JSC «Ural Steel» are presented. For heating of water in the experimental water heater uses the heat radiated from the surface of the sintering mixture. The dynamics of the sinter mix temperature during the technological stages of its preparation from pelleting to loading on pallets was studied, de-pending on a water temperature change during pelletizing.

It was defined that for the conditions working of the sintering machine No. 1 of JSC «Ural Steel» the water tempera-ture increase which supplied of the pelletizer to moistening, for every 10 °C, facilitates an increase in the temperature of the sinter mix on the pallets by 1.5-1,6 °C.

For the stable sinter mix production with a temperature of more than 55 ° C, it is necessary to use water supplied to the pelletizer for moistening, with a temperature of at least 85°C. To implement the proposed technology, it is necessary to equip the sinter machines with water-heating recuperative heater, installed above the sintering machine behind the ignition hood and using heat, radiated from the surface of the sinter cake.
