A cutting position control device , comprising: multiple sensors to detect positions and feed distances of slabs; and an arithmetic processing circuit that is configured to receive an input of first data including information relating to a production schedule such as a production timing, and material information of a material to be produced, use the first data to calculate a first cutting position (C0) of a first cutter for a first slab cast by continuous casting equipment, generate a first parameter for setting the first cutting position (C0) for a control program to be introduced to a process control device , and determine whether or not to use a second cutter to further cut a second slab of a second length (L), which has been formed by cutting the first slab based on the first parameter, by comparing the second length (L) and a first length (L0) set to correspond to a length from a front end of the first slab to the first cutting position (C0), the second cutter being located downstream of the first cutter , when the second length (L) is equal to the first length (L0) or less than the first length (L0), the arithmetic processing circuit is configured to set the second slab to be fed to a next process without being cut by the second cutter , when the second length is greater than the first length (L0), the arithmetic processing circuit is configured to generate a second parameter for setting a cutting position for the second cutter to further cut the second slab . multiple sensors to detect positions and feed distances of slabs; and an arithmetic processing circuit that is configured to receive an input of first data including information relating to a production schedule such as a production timing, and material information of a material to be produced, use the first data to calculate a first cutting position (C0) of a first cutter for a first slab cast by continuous casting equipment, generate a first parameter for setting the first cutting position (C0) for a control program to be introduced to a process control device , and determine whether or not to use a second cutter to further cut a second slab of a second length (L), which has been formed by cutting the first slab based on the first parameter, by comparing the second length (L) and a first length (L0) set to correspond to a length from a front end of the first slab to the first cutting position (C0), the second cutter being located downstream of the first cutter , receive an input of first data including information relating to a production schedule such as a production timing, and material information of a material to be produced, use the first data to calculate a first cutting position (C0) of a first cutter for a first slab cast by continuous casting equipment, generate a first parameter for setting the first cutting position (C0) for a control program to be introduced to a process control device , and determine whether or not to use a second cutter to further cut a second slab of a second length (L), which has been formed by cutting the first slab based on the first parameter, by comparing the second length (L) and a first length (L0) set to correspond to a length from a front end of the first slab to the first cutting position (C0), the second cutter being located downstream of the first cutter , when the second length (L) is equal to the first length (L0) or less than the first length (L0), the arithmetic processing circuit is configured to set the second slab to be fed to a next process without being cut by the second cutter , when the second length is greater than the first length (L0), the arithmetic processing circuit is configured to generate a second parameter for setting a cutting position for the second cutter to further cut the second slab . <EOS>
