Method for automatic pouring of thin sheet bar continuous casting machine

The invention provides a method for automatic pouring of a thin sheet bar continuous casting machine. The method comprises the steps of preheating a pouring box; injecting molten steel in a steel ladle into the pouring box, and using a pouring box stopper to automatically operate to inject the pouring box molten steel into a crystallizer; detecting a molten steel liquid level by a radiation source, adding protective slag, when the molten steel liquid level reaches 125 mm, automatically activating secondary cooling water, crystallizer vibration and a tension leveler, and setting the pulling seed of the tension leveler; when the pulling speed is 3.5m/min and a stable casting blank tracking value ranges from 3m to 5m, using an eddy current sensing to detect the molten steel liquid level; whenthe molten steel liquid level floating range is+-1mm and the casting blank tracking value ranges from 5m to 8m, after the electromagnetic brake is in normal operation, pressing a dynamic liquid core,completing automatic pour
