PROBLEM TO BE SOLVED: To provide continuous casting equipment provided with an oxygen cutting-off machine excellent in operating safety, reliability, easy maintenance, operating speed and efficiency. SOLUTION: The oxygen cutting-off machine 1 is designed for a billet, bloom, slab or large scaled plate in one pair of rails 3 disposed at the upper side and the lower side. The oxygen cutting-off machine 1 is provided with a heat- resistant plate 6 and a mechanical parts provided below the rails 3 is cooled. The oxygen cutting-off machine 1 is shifted in the lateral direction together with a deflected working material 2, and a fastening device and a fastening skid for keeping up with the materials 2 having various thicknesses, are provided and further, a cutting-off pushing rod for mutually cutting off with two sets of oxygen cutting-off burners 9 is provided. A quick exchanging device for new oxygen cutting-off burner 9 or nozzle is improved to the cutting efficiency and the maintenance. The cutting-off safety and the cutting-off quality are improved by controlling the gas pressure and flow rate near the burner.
