The Distribution of Temperature and Block Corrosion in Glass Tank Furnaces

JSGT 1929 V13 T140-T166

Laboratory tests have from time to time been devised in order to determine the suitability of various materials for use in tank block manufacture. Whilst, by these tests, the solvent action of the batch on the block and the physical changes which take place when the block material comes in contact with melting batch or molten glass can be sufficiently well determined, it is, nevertheless, impossible to reproduce in a laboratory test the exact conditions to which the block is subjected when built into the furnace. In order to obtain some information with regard to the rate of corrosion of blocks in different positions in the tank and exposed to different conditions as regards temperature and movement of the molten glass or semi-molten batch, investigations were instituted in 1924 by the Glass Research Association and the following is an account of these investigations and of the results obtained.
