Casting flow tracking system of continuous casting machine

Abstract

The invention discloses a casting flow tracking system of a continuous casting machine, which is used for successfully measuring actual positions of a blank and a dummy bar in a sector section and casting length of a casting blank through a plurality of encoders, a high-speed calculation template, a signal source counting overflow processing module, a signal source correct recognition and screening module and a tracking calculation module, wherein the plurality of encoders are arranged at a plurality of sector sections to drive a rear shaft of a drive motor, and the measuring process is safe,and is safer and more reliable compared with single-point detection; the signal source counting overflow processing module improves the reliability and the tracking precision of the signal source; and the signal source correct recognition and screening module recognizes a reference signal source from the plurality of encoders to overcome the defect of signal distortion of the signal source causedby using the selected fixed signal source as the reference signal. A human-computer interface unit determines the actual diameter of a drive roller according to the abrasion condition of a mechanicalroller and solves the problem of error compensation of the tracking data caused by the abrasion of the mechanical roller. A tracking classification processing module and a delivery continuous castinguser data module can realize the application of the calculation result.

Description

technical field [0001] The invention relates to a casting strand tracking system of a continuous casting machine Background technique [0002] The continuous casting process is a classic conversion process between steelmaking and steel rolling in steel production, and its quality directly affects the success rate and quality of rolled steel products. The casting strand system is the key and main link of the continuous casting process. Divided from the process area, the casting strand system includes dummy bar storage and conveying device, crystallizer, primary cooling water, tension straightening machine (sector section), secondary cooling water, stripping roller, dummy bar receiving device, etc. The main tasks of the process are receiving and sending dummy rods, slab and dummy rod position tracking, stripping control, billet liquid core tracking, primary and secondary cooling water, billet casting speed control, ASTC control, etc. The realization of these technological pr...
