LABELING METHOD AND CONTROL METHOD OF MARKING MEASURE IN STEEL MATERIAL LABELING SYSTEM

摘要

PURPOSE: A labeling method and a marking unit control method for a steel material labeling system are provided to correctly mark information such as characters and images at a desired position of the steel material by moving an ink head in consideration of a moving speed of the steel material. CONSTITUTION: Steel material information, which is basic information of a steel material, is received. A measurement result is generated by measuring the size of the steel material(S20). An image file is generated by using the measurement result(S40). A moving speed of the steel material is calculated(S60). The steel material is marked by moving a marking unit according to the calculated moving speed of the steel material(S80).
