The top off the mold is covered with endless steel belt pressed against the mold with the help of belt pressing roll. Two rows of adjustable type SS nozzles are provided for the cooling of in-ner mold wall. Segment type outer spray with SS nozzles is provided for belt cooling.

OPERATION
The operation of strip caster is simple. It requires very less man power and it produces continuous strip from 100 to 300 mm width, 16 to 24 mm thickness of consistent quality. The temperature of strip so produced is nearly 450 degree centigrade close to hot rolling temperature and can be fed directly to hot rolling mill for the thickness reduction. Continuous casting and hot rolling operation can be performed simultaneously. The output is very high and of consistent quality. The percentage yield is also very high compared to book mold process as there is no end wastage. The product has very fine grain size as the rate of cooling is high. The deep drawing properties are better than conventional book mold process.
