The reasons for the short service life of the lining of the tap holes in ore-roasting furnaces at nickel and tin factories are analyzed. It is established that the main reasons are the large number of seams in the lining and the low resistance of the sintered periclase-chromite refractories to slag and abrasion.Work has been done to create a seamless design of tap hole made of a slag-resistant refractory. Blocks made of PShFB-grade refractories have been developed along with a fused periclase-chromite refractory (grade PKhPP) and a new high-temperature adhesive. Use of the seamless tap holes has increased the life of their lining by a factor of 2.0 – 2.5.
