HEATING SYSTEM OF RAILWAY TURNOUTS IN METALLURGICAL PRODUCTION Russian patent published in 2017 - IPC E01B7/24 

FIELD: heating.

SUBSTANCE: heating system (3) of the turnouts (4), operating in the area of the hot metallurgical unit (2), contains the thermal energy source in the contour form (1) of the particular unit industrial cooling waters. Turnouts (4) are included in the closed loop (5) of their heating. The system contains the heat exchanger (6), the valve (7), regulating the water supply to the heat exchanger (6), the circulating pump (8), driving the coolant along the contour (5). The heating elements (9) are fixed to the frame rails (10) and also on the turnouts cushions (11) and the turnouts plates (12) of the turnouts cushions (11). The pipes (13) to deliver the coolant from the heat exchanger (6) to the turnouts (4) and laid back in the soil to the depth of not less than the depth of its freezing and wrapped with insulating material.

EFFECT: possibility of structure operation efficiency increase.
