Causes of {open_quotes}undercut{close_quotes} development in coke-oven brickwork
By no means the least important fault that can develop in coke-oven refractories, and which lowers the productivity and shortens the life of coke-oven batteries is the development of so-called {open_quotes}undercuts,{close_quotes} whereby longitudinal fissures of variable depth and length appear in the first one or two rows of bricks form the floor. On the other hand, large-scale undercutting only develops in individual batteries, and many coking plant workers employed in the servicing and upkeep of the coke ovens are unfamiliar with the problem. No convincing explanation has yet been forthcoming, and consequently no effective measures have been laid down for its prevention. The first large-scale outbreak of undercutting in this country occurred in 1956-1957, in No. 1-4 batteries (side heating) at the Kuznetsk and Magnitogorsk II & SW-plants. 2 refs., 3 tabs.
