FOUNDRY COKE WITHOUT COAL: MORE THAN HALF- CENTURY OF PRODUCTION IN ARGENTINA

摘要

A foundry coke industry is well established in Argentina, using blends of essentially petroleum coke and coal tar pitch for the production of cupola coke in non-recovery oven batteries. The paper includes a detailed discussion of the raw materials base (including doal tar pitch substitutes that have been used at some time), the criteria followed for the blend design, the main features and operation of the coke ovens, the coke quality obtained and the specificities of the behavior of this coke in the cupola.
