VERFAHREN ZUM ABREISSEN DER AUSKLEIDUNG EINES OFENS O.DGL.

摘要

This invention relates to a method of delining a furnace intended for high temperature melts, such as glass or metal melts. The lining of such a furnace usually consists of a material which closest to the furnace wall forms a layer of pulverulent material and which outside this layer consists of a layer of a very hard, almost infrangible outer mass. For such delining operation the invention suggests first removing material from the inner layer and then breaking up the outer layer in the regions where material from the inner layer has been removed. Thus, the hard outer layer is exposed and worked without any material from the inner layer in place as a support.
