A computer program for the digital image correlation method was developed using the pattern matching. The deformation behaviors of the refractories under compression, cylinder splitting and thermal shock tests were analyzed in the samples using the program. In these tests, generation and propagation of cracks were observed in strain distribution. The displacement measurement of brick and jig in the slide gate plate setting was also carried out, and deformation behavior of each part was grasped. The method is useful for monitoring the deformation behavior of whole sample of the refractories when the measurements using strain gauge and linear displacement gauge are difficult. Source

The lances for hot metal pretreatment are damaged mainly because of cracking. The mixture containing roseki aggregate of both 1-3 mm and 0-1 mm grain size was examined in thermal spalling test. The test result was fairly good. In this mixture, however, it resulted not only deterioration of the hot strength but also increase of the sintering effect. The hot strength was increased and also the excessive sintering effect was controlled sufficiently by means of adding mullite and alumina in the ratio 1:4.The castable obtained as described above was subjected to a hot service trial and accomplished satisfactorily showing a substantial improvement in controlling cracks and increasing the hot service life of the lance.
