Abstract

A method of producing a continuously cast metal rod capable of producing a high-quality continuously cast material is provided. In the method of producing a continuously cast metal rod, a cooling liquid is supplied to each of outer peripheral surfaces of a plurality of ingots extracted from a plurality of molds in parallel to cool each of the plurality of ingots. In a predetermined ingot, the number of adjacent ingots is the number of other ingots arranged around the predetermined so as to face the predetermined ingot, and an ingot small in the number of adjacent ingots is cooled with weak cooling in which the degree of cooling by the cooling liquid is reduced with respect to an ingot large in the number of adjacent ingots.

First claim

The invention claimed is:

1. A method of producing a continuously cast metal rod in which a cooling liquid is supplied to each of outer peripheral surfaces of a plurality of ingots extracted from a plurality of molds in parallel to cool each of the plurality of ingots,
wherein when a number of other ingots arranged around a predetermined ingot so as to face the predetermined ingot is defined as a number of adjacent ingots, an ingot smaller in the number of adjacent ingots is cooled with weak cooling in which a degree of cooling by the cooling liquid is reduced with respect to an ingot larger in the number of adjacent ingots.

2. The method of producing a continuously cast metal rod as recited in claim 1 ,
wherein a supply quantity of the cooling liquid to the ingot smaller in the number of adjacent ingots is set to be less than a supply quantity of a cooling liquid to the ingot larger in the number of adjacent ingots.

3. The method of producing a continuously cast metal rod as recited in claim 1 ,
wherein supply pressure of a cooling liquid to the ingot smaller in the number of adjacent ingots is set to be lower than supply pressure of a cooling liquid to the ingot larger in the number of adjacent ingots.

4. The method of producing a continuously cast metal rod as recited in claim 1 ,
wherein a degree of cooling of each ingot is set to be equal to each other over an entire circumference of each ingot.

5. The method of producing a continuously cast metal rod as recited in claim 1 ,
wherein when a region of an outer peripheral surface of the ingot that is open and does not face another ingot is defined as an open region, and a region of an outer peripheral surface of the ingot that faces another ingot is defined as an ingot facing region, the open region is cooled in a state in which a degree of cooling by a cooling liquid at the open region is set to be less than a degree of cooling of a cooling liquid at the ingot facing region.
