Installation notes

  1. 1Lay dry or with thin carbon-bonded mortar; keep joints tight (under 1 mm where possible)
  2. 2Match carbon level to duty: lower C for metal line, higher C (16–18%) for slag line
  3. 3Limit oxidising atmosphere during heat-up to protect the carbon bond
  4. 4Antioxidant-containing grades develop a dense protective zone in service
