摘要： A continuous casting method enabling a stable longtime casting due to a lubricating effect while preventing non-realization of lubricating effect due to short supply of lubricant and molten steel pollution and additional pouring associated with excessive supply of lubricant and for producing a thin cast piece by injecting molten metal into a pouring basin portion formed between a pair of cooling drums and a side dam and cooling molten metal by rotating circumferential surfaces of the cooling drums for solidification, the method being characterized in that casting is carried out while a solid lubricant is continuously pressed against an end surface of the cooling drum located at an upstream position of drum rotating direction entrance side of the side dam in a working temperature range by using the side dam chamfered at the drum rotating direction entrance side portion of a ceramic plate that is in sliding contact with the end surface of the cooling drum, the solid lubricant being pressed against the drum end surface at a surface pressure of 2 kgf/cm to 15 kgf/cm or a forcing speed of 0.1 to 10 mm/min for continuous supply.
