Abstract
The coating is applied by (a) spraying the base-plate and the lower part of the mould wall with one substance or mixt. followed by (b) spraying the remainder of the mould wall with a second substance or mixt. The device pref. consists of two sprays moulted on one head and arranged so that after the head is lowered into the mould, one spray with an angle of 30-90 degrees is used for stage (a) and the head is then raised while the second spray, operating over 360 degrees at right-angles to the mould axis, carries out stage (b). Coating (b) is designed to improve the surface of the ingots and pref. consists of a mixt. of molasses with a synthetic product contg. asphaltene. The treatment thus proects the base-plate with a ceramic coating and coats the mould wall in one operation.
