Problems solved by technology

[0003] In continuous casting, due to the relatively small volume of the tundish, the buffer time of the molten steel is short, the inclusions cannot be fully separated and floated up, the fire resistance of the materials used is poor, and the service life of the stopper is relatively short; the original secondary cooling section only has two sections , the cooling is not sufficient, when the casting speed is increased, defects such as cracks and bulging are

Abstract

The invention discloses a novel continuous casting machine which comprises a steel ladle, N middle ladles, a crystallizer, a secondary cooling system, a tension leveler, a bending roll, a straightening roll and a flame cutting machine which are connected in sequence. A sliding nozzle is arranged in the bottom of the steel ladle; stoppers connected with stopper rods are arranged in the middle ladles, and the sliding nozzle is arranged under the stoppers; the steel ladle is connected with the middle ladles, wherein the N is greater than 3; the volume of the middle ladles is 36t; secondary cooling water is divided into four sections and is provided with 8 sets of supporting rollers. By the arrangement, steel-water buffering time can be prolonged by the larger volume of the middle ladles, occluded foreign substances have sufficient time to separate and float, and stability of liquid level is sustained; cooling intensity can be further strengthened, and service life of the middle ladles and the stoppers can be prolonged; the entire process of continuous casting is monitored, and problems are timely found and regulated; resources are saved, and utilization rate is increased; productivity and quality in casting blanks are improved.

Description

technical field [0001] The invention relates to a continuous casting machine, especially a new high-efficiency continuous casting machine capable of automatic operation, and also relates to a control system and a control method of the continuous casting machine. Background technique [0002] The production process of continuously casting high-temperature molten steel into a billet with a certain cross-sectional shape and a certain size specification is called continuous steel casting. The equipment required to complete this process is called continuous casting equipment. The electromechanical and hydraulic integration of steel pouring equipment, continuous casting machine body equipment, cutting area equipment, dummy bar collection and conveying equipment constitutes the core equipment of continuous steel casting, which is customarily called continuous casting machine. Continuous casting has the greatest impact on the structure of steel plants, and continuous casting is the...
