THREE D METAL has employed VSR Technology On-Site Service on two previous projects, involving 250-ton capacity Lifting Yokes and 400-ton capacity Clamshells. In this latest project, performed at GERDAU’s Knoxville, TN mill, a Lower Shell for an electric arc furnace, measuring 30′ L, 20′ W, and 10′ H, was stress relieved in less than 3 hours using the VSR Process. In addition to relieving the weld stresses produced in THREE D METAL’s shop during fabrication, the Job also required stress relieving a full-length field weld, joining the two Furnace Halves.
