OVERCOOLING IN OVERLAPPING AREAS DURING HYDRAULIC DESCALING

Popis výsledku v původním jazyce

The production and processing of high quality grades of steel is connected with oxidation at high temperatures. Unwanted scales are formed on the steel surface, which is usually heated over 900°C. These scales are often removed by hydraulic descaling during production. In most cases where long, flat products are produced, one row of descaling nozzles is used. Because these flat jet nozzles are arranged in the row, the water spray from one nozzle interferes with the spray from neighboring nozzles. This zone is called an overlap area and oftentimes more scales remain here after the descaling process. An increased amount of scales left behind result in a lower quality final product. The typical configuration with an inclination and twist angle equal to 15° was studied. Heat transfer coefficients (HTC) and surface temperatures were measured in the overlap area and compared with values obtained from undisturbed areas. It was found that the overlap area is grossly overcooled. Results were co
