The ingot mould made of cast steel, instead of cast iron, were adopted by our Works to lessen the increased consumption caused by lack of pig iron and coke of good quality.
The results were satisfactory enough: the slab mould weighing 1, 200kg endured to the contineous use of average 142 times. The suitable carbon content was 0.4-0.5%. The special device was taken to avoid its strain by heat.
The author expects, under present condition of Japan, 3-5 times durability compared to that of cast iron mould, whereas the manufacturing cost of it falls 2-3 times of the latter.
