Abstract

Se proporcionan un método de laminación en frío, equipo de laminación en frío, y un método de fabricación de lámina de acero laminada en frío capaz de evitar rotura de la lámina al suprimir suficientemente la ocurrencia de una grieta en el borde de un material a laminar durante laminación en frío. En el método de laminación en frío, un tren de laminación (2) que incluye una pluralidad de soportes (31) hasta (34) lamina en frío un material a laminar (S). Un soporte N-ésimo (3N) (N es un número natural igual a o mayor que 2) configurado en una posición N-ésimo desde un lado de corriente ascendente del material a laminar (S) en una dirección de transferencia entre la pluralidad de soportes (31) hasta (34), incluye un rodillo de trabajo cónico (4a1) que tiene una conicidad (4ab) formada en una parte final de un rodillo (4aa) que tiene un diámetro uniforme. El soporte N-ésimo (3N) lamina el material a laminar (S) con una carga lineal de 0.8 t/mm o más.A cold rolling method, cold rolling equipment, and a cold rolled steel sheet manufacturing method capable of preventing sheet breakage by sufficiently suppressing the occurrence of a crack at the edge of a material to be rolled are provided. during cold rolling. In the cold rolling method, a rolling mill (2) including a plurality of supports (31) to (34) cold rolls a material to be rolled (S). An Nth support (3N) (N is a natural number equal to or greater than 2) configured at an Nth position from an upstream side of the material to be rolled (S) in a transfer direction between the plurality of supports (31) to (34), includes a conical work roll (4a1) having a cone (4ab) formed in an end portion of a roll (4aa) having a uniform diameter. The Nth support (3N) laminates the material to be laminated (S) with a linear load of 0.8 t/mm or more.
