With recent capital expenditures, Perryman has more than doubled its melting capacity which is now in excess of 26 million pounds annually. Today, the company boasts two electron beam cold hearth furnaces and three vacuum arc furnaces. Depending on customer requirements we can melt titanium as either single, double or triple melt.
Our melting facility employs Electron Beam Cold Hearth Melting (ECHB) and Vacuum Arc Remelt (VAR) technologies, both of which operate under vacuum. These melting techniques allow us to optimize management of raw materials while providing our customers with a reliable, one-stop supplier of choice. We recycle nearly 100% of our own internally generated titanium scrap.
Most of the titanium material at Perryman is double melted. The first melt utilizes electron beam (EB) technology to melt the blend of raw materials through a cold hearth, casting 12,500-pound electrodes. Cold hearth melt refines the material, assuring a high-quality product for critical applications in aerospace, medical, and other industries.
The next step is to remelt the EB electrode in the VAR furnace. During this process, the electrode is further refined. Through the use of a carefully controlled melt rate, the arc melts one end of the vertically positioned electrode into a crucible, where it cools and solidifies. Our two-station VAR furnace allows one ingot to cool while another electrode is melting, resulting in an efficient process with maximized throughput.
Depending on customer requirements, Perryman can triple melt to produce an ingot. In this process, an additional VAR is added.
Both the EB and VAR melting operations are constantly monitored by Perryman’s highly trained technicians to ensure reliable, well-controlled melt practices and superior quality titanium ingots.
