Fine atomization Semi-fine atomization Semi-coarse atomization Coarse atomization There are many opinions on the classification of spray droplet sizes but IKEUCHI, "The Fog Engineers", have classified them as above and propose optimized fog for specific requirements and work-environment conditions.

Classification of Spray Droplet Size IKEUCHI Cooling Technology: Cooling effects and conditions, Guarantee of precision nozzle performance Cooling technology Fog spray cooling systems, Profile of supporting data Nozzle applications for each process: Raw material & iron making process Steel making process Plate mill/ Hot rolling mill/ Cold rolling mill Surface finish, other processes Spray Nozzle Materials Specifications of the products and contents of this catalog are subject to change without prior notice for purpose of product improvement.

IKEUCHI provides high-quality spray nozzles and control systems, CFD simulation analysis, and cooling trial experiments combined with an outstanding performance record for the steel industry. Cooling effects and conditions I The effect of spray cooling is dependent on the fog, the cooling target, the environment and the cooling medium. I IKEUCHI measures each aspect of fog spraying performance and uses CFD simulation to create plans for the optimum cooling conditions. Spray Capacity Tolerance Guaranteed to within +/- 5% of the rated spray capacity under the standard pressure. Within 3°...

IKEUCHI Cooling Technology For cooling of hot slabs, strong impact force is needed to break through the film boiling. Through cooling trial experiments, we can provide the optimum nozzles and layout. Cooling for surface finishing of steel slabs requires a large amount of fine fog to produce a smooth surface texture. IKEUCHI has been developing low-energy atomizing nozzle units. Cooling of high temperature flue gas such as sintering exhaust requires spray control and droplet diameters that yield complete evaporation. IKEUCHI uses CFD simulation when selecting the control system and nozzles...

We provide custom systems including the appropriate nozzles, equipment and controls to meet our customers’ needs. By utilizing optimal system control technologies it becomes possible to achieve ideal cooling system performance. Profile of supporting data To aid in cooling nozzle selection, IKEUCHI can perform a variety of measurements and simulations.

In this catalog the materials of nozzles are described using the material codes listed below. As "The Fog Engineers", we, IKEUCHI, have been developing nozzles in a variety of materials to meet the desires and applications of our customers. We were the first to develop ceramic orifice-inserted spray nozzles and succeed in marketing them throughout the world. Listed below are the materials of nozzles and parts, and resistance characteristics of each material against common chemicals. Items Materials • As for the spray nozzles including adhesive, please also take into account the...
