Abstract

The invention discloses an off-line test system for an embedded molten steel liquid level sensor of a crystallizer. The system comprises the molten steel liquid level sensor, a simulated molten steelliquid level measuring device, a crankshaft linear stroke vibration device and a control device. The molten steel liquid level sensor is used for detecting displacement difference between the simulated molten steel level measuring device and a fixed sensor platform on the crankshaft linear stroke vibration device to obtain a real-time molten steel level signal, outputting the real-time molten steel level signal to the control device, detecting vibration frequency of the crankshaft liner stroke vibration device to obtain a real-time vibration state signal of a simulated crystallizer, and outputting the real-time vibration state signal of the simulated crystallizer to the control device. According to the off-line test system for the embedded molten steel liquid level sensor of the crystallizer, an off-line dynamic test of on-site operation stimulation of the embedded molten steel liquid level sensor of the crystallizer is achieved.

Description

technical field [0001] The invention relates to the technical field of crystallizer non-contact detection equipment, in particular to an off-line testing system for an embedded mold molten steel level sensor. Background technique [0002] In the slab continuous casting production process of iron and steel enterprises, the molten steel level detection technology of the mold has always been one of the core technologies of the production process control. The occurrence of major production accidents caused by steel is also an important technical guarantee for realizing automatic casting, improving continuous casting production efficiency, and reducing the labor intensity of staff. [0003] At present, most domestic large and medium-sized steel mills use imported embedded mold steel liquid level sensors on the molds produced by slabs. However, due to the high cost of imported detection equipment from abroad and the harsh operating environment on site, it has become a consumable p...
