Description:

There are many areas in the steel and metallurgy industry where pure water cannot be used as a coolant. Lubrication and corrosion are the two main factors why spray cooling has to use different cooling liquids. A typical example is cold rolling of steel where emulsions are used or rolling of some non-ferrous metals where pure oils are used. Other metallurgical processes use water polluted by oil or containing mineral salts. The spray cooling efficiency of these coolants is different from the cooln slats. The spray cooling efficiency of these coolants is different from the cooling efficiency of pure water. This paper describes a research comparing the spray cooling by pure water to the cooling using water-base oil emulsions of different concentrations, cooling using oil, and cooling using polluted water. This comparison was done by the measurements of the cooling efficiency characterised by the heat transfer coefficient for identical pressure. and Obsahuje seznam literatury
