Production of unfired tarred -dolomite brick and its service in 100-TON oxygen converters

  • Published:
Refractories Aims and scope

Conclusions

The use, in the production of unfired articles, of highly sintered granular dolomite without additional grinding and coal-tar pitch with a high content of pitch, ensures, after pressing of the hot bodies, the production of dense and strong articles capable of being stored in air in winter for 10–12 days.

To further improve the resistance of the unfired lining, it is necessary to continue the investigation of the effect of metallurgical factors on the resistance of the unfired refractories during service in converters, and to establish the optimum parameters for the oxygen-converter melting cycle.
