Abstract

In the manufacture of steel and foundry coke, there are a series of circumstances inherent to the process which can affect the life of the refractory material with which the ovens of the batteries are built. This article will deal with the impact of aspects such as sticky ovens and hard pushes on the refractory. For this purpose, data will be obtained from a Didier design coke plant built in the 1970s. In particular, the data comes from two batteries or groups of ovens over a period of two years. Of the types of refractories of which coke batteries are composed, we will only deal with silica material. This is the type of refractory with which the combustion and coking chambers of the ovens are almost exclusively built. Its characteristics and behavior make silica a major player in the service life of a coke battery. Therefore, any aspect of the process that is susceptible to damage during this refractory will have a great impact on the life of the coke manufacturing equipment. The results show that hard pushes and especially sticky ovens damage the silica refractory of the furnaces. Therefore, the proper management of production, focused in minimizing these effects, can contribute to reduce the maintenance cost and prolong the service life of the coke ovens.
