Abstract
The invention relates to a method for processing heated material (1), wherein the material is guided along a conveying path and is covered and protected against heat loss in the region of the conveying path by at least one reflector element (2), wherein the reflector element (2) is cooled by means of a liquid. According to the invention, in order to guarantee efficient cooling of the reflector without costly measures, the liquid is glycol or comprises glycol or the liquid is alcohol or comprises alcohol or the liquid is thermal oil.
Claims11
A method for processing hot metal slabs, sheets and strips and similar material (1), wherein the material is guided along a conveying path and is covered and protected against heat loss in the region of the conveying path by at least one reflector element (2), wherein the reflector element (2) is cooled by means of a liquid, characterized in that
- the reflector element includes a reflector material having a reflectivity of greater than 70%,
- that the liquid is glycol or comprises glycol or in that the liquid is alcohol or comprises alcohol, or in that the liquid is thermal oil, and that during cooling, the liquid is heated only to a maximum temperature at which it still will not produce vapor pressure,
- that the liquid is conducted within a closed circuit through the reflector element (2), thereby passing one heat exchanger (3), and
- that the liquid is held at a predefined temperature by controlling a liquid flow rate based on an actual temperature of the reflector element as the liquid passes through the closed circuit, so that the liquid is kept from evaporation, wherein a volumetric flow rate is used as a control variable.
