In our plant major part of finishing work of large steel casting except machining is effected by chipping which needs heavy labour, occupying considerable time. So we introduced carbon-arc-blasting process for large steel castings, which blow away molten metal by compressed air as rapidly as it is melted by carbon arc. This process promoted efficiency and reduced finishing costs of the fettling plant remarkably, and its special features are as follows : 1. Cracks caused by heat effect are never appeared in plain steel castings. 2. Alloy steel castings sensitive to cracks could be cut without the danger of cracking, providing a proper preheating is used. 3. Surface grade of the arc air blasted casting is far more smooth than gas scarfed one and almost equal to as cast surface. 4. Working efficiency of the process on the carbon steel casting is about eight times compared with the conventional process and shows it's superiority on the alloy steel casting especially for stainless steel.
