Abstract
While an insufficient lubricating effect caused by lack of lubricant is prevented and also while contamination of molten metal and insertion of molten metal caused by excessive feed of lubricant are prevented, a lubricating effect can be provided and continuous casting can be conducted over a long period of time. Molten metal is poured into a molten metal pool formed by a pair of cooling drums and side dams. The thus poured molten metal is cooled and solidified on circumferential surfaces of the cooling drums, so that a strip can be produced. In the above continuous strip casting method, the side dam is composed in such a manner that a portion of the ceramic plate on the inlet side in the rotational direction of the cooling drum is chamfered, wherein the portion comes into contact with an end surface of the cooling drum. Onto the end surface of the cooling drum at a position in the upstream on the inlet side of the side dam in the rotational direction of the cooling drum, solid lubricant is pushed at a temperature in the usable temperature range, so that lubricant can be continuously fed. While the lubricant is continuously fed in this way, continuous casting is carried out. In thi…
