1. A cutting position control device, comprising:
a first sensor configured to detect a length of a first slab cast by continuous casting equipment;
a second sensor configured to detect a length of a second slab, the second slab being cut from the first slab by a first cutter; and
an arithmetic processing circuit configured to
receive an input of first data including information relating to
a production schedule, and
material information of a material to be produced,
use the first data to calculate a first cutting position of the first cutter for the first slab,
generate a first parameter for setting the first cutting position for a control program introduced to a process control device, and
determine whether or not to use a second cutter to further cut the second slab of a second length based on the first parameter by comparing the second length and a first length set to be from a front end of the first slab to the first cutting position, the second cutter being located downstream of the first cutter, the first length being detected by the first sensor, the second length being detected by the second sensor,
wherein when the second length is equal to the first length or less than the first length, the arithmetic processing circuit sets the second slab to be fed to a next process without being cut by the second cutter,
wherein when the second length is greater than the first length, the arithmetic processing circuit generates a second parameter for setting a cutting position for the second cutter to further cut the second slab.
