The development stage of steel billet sprayforming is less advanced than it was expected at the start of the study. This has shifted somewhat the emphasis of the project from production-oriented activities such as detailed plant engineering and user tests of material, to material investigation and theoretical study of causes of bad material quality. Simulation experiments surprisingly suggest that twin-nozzle atomization could in fact improve flow conditions in the spray chamber. (The latest information from Osprey Metals Ltd supports this result with good results from the billet plant). This is very interesting since twin-nozzle systems can be neccessary to reach resonable throughput and larger diameters. Process control equipment is being developed for sprayforming. The most difficult parameter to control accurately over longer periods of time is the metal flow rate.
