This Part of BS 7335 describes good practice for working procedures in the installation of refractory linings by gunning techniques. The code is specifically concerned with the “dry” gunning of initial or replacement linings, using refractory materials bonded by calcium aluminate cement. Major repairs, involving the removal of old panels of the lining back to the shell, are also covered. Recommendations for ensuring that compliance with the agreed design has been achieved are included, where appropriate.

Wet gunning and gunning repairs to hot linings are excluded. The gunning of linings for steel chimneys is specifically described in BS 4207.

NOTE The titles of the publications referred to in this standard are listed on the inside back cover.
