Objective
The available chemical and mechanical processes for descaling of high alloy steels and tool steels take up a great deal of space, are expensive and time- consuming, present health hazards for the workforce and severely pollute the environment. Also, the surface quality of the descaled materials often non- longer satisfies the more demanding requirements of manufacturing. EDT is an innovative solution to these problems. The EDT process removes the oxides from the surface of the material under vacuum through the action of current and voltage together with lengthways movement of the scale-coated rod or bar. To validate an industrial mode of operation, industrial field tests of scale removal will be carried out on selected high alloy steels and tool steels. Improvement of the properties in subsequent mechanical treatment is a further object of the study.
