The Temperature Decrease of the Treated Cast Iron Using an Injection
S. Borkowski
Abstract
An out furnace treatment of the cast iron using compressed air to make up powdered additions is connected with endothermic effects. The results of the cast iron temperature decrease under conditions of the natural self-cooling as well as after the compressed air injection at various depths and time have been presented in the work. It was pointed out that the temperature decrease of the liquid cast iron during a foreblowing is proportional to the depth of the lance draught. An application of the protective coating (a graphite layer of slag as a covering) reduces 20 % of the temperature decrease of the treated cast iron. Some active methods of the experiments planning have been used in the research.
