REFRACTORY SYSTEMS

摘要

A continuous casting machine includes two casting rollers (2) which define a gap communicating with a reservoir of molten metal. Urged into sliding contact with a proportion of the area of the end surfaces of the casting rollers are respective side dams (3). Particulate solid refractory lubricant material which is in flowable form but has no added liquid is applied to the end surfaces of the casting rollers at positions shortly before they come into sliding contact with the side dams. The lubricant material occupies the interface between the casting rollers and side dams and seals it from the ingress of molten metal and protects the sliding surfaces from abrasion.
