BOC Gases, a member of the Linde Group, signed a multiyear contract worth over $20 million with Gerdau Ameristeel. BOC, which currently supplies Gerdau''s Knoxville, Tenn., steel mill with liquefied oxygen and nitrogen, will construct an air-separation unit to provide the mill with over 130 tons per day of gaseous oxygen and nitrogen.
The Knoxville mill recycles scrap metal to produce long products such as rebar. It is one of four Gerdau steel mills in the U.S. that BOC supplies under multiyear contracts. The Linde Group supplies over $1.1 billion of gases each year to steel customers.
