Development of a spray-forming process for steel. Semiannual program report for the period ending February 28, 1990.

摘要

The principal objective of this program is to develop a near net- shape casting technology based on spray atomization and deposition for the production of low-carbon steel sheet and plate with estimated energy and cost savings of $20/t and $50/t, respectively. The properties produced with this process are generally equivalent or greater than that obtained with conventional continuous or ingot casting practices. Although the effort in this program is currently directed toward flat products, the technology has the flexibility to produce materials in a variety of thicknesses and shapes. Furthermore, enhanced versions of the technology will be able to produce high margin products, such as coated steel, in relatively few operations compared to the current flow sheet. The production of new materials, such as steel-based composites, is also possible with this technology. The combination of enhanced properties, new materials, and shaped products distinguishes the spray forming technology from all other near net-shape casting processes. 47 refs., 67 figs., 7 tabs.
