EXPLOSION OF A TITANIUM FURNACE AT THE JESSOP SAVILLE WORKS, SHEFFIELD

An investigation into the explosion of a titanium arc-furnace is briefly described, and photographs of the more important pieces of wreckage are given. The accident is attributed to insufficient cooling of the copper base of the crucible and there is clear evidence of penetration. The main damage is attributed to chemical action between molten titanium and some of the cooling water. Comparisons with steel melting are also made and there is a brief discussion of other potential hazards. It is suggested that most of the essential precautions here recommended are being taken in more modern designs of equipment.
