Abstract

The invention discloses double-sensor molten steel liquid level measuring equipment. The equipment is based on non-contact type liquid level eddy type sensors, and multi-disciplinary technologies such as an electro-magnetic induction technology, a signal processing technology and a computer technology are fused. Compared with a traditional single sensor, double sensors have the advantages that a false liquid level can be well detected, and stability is great. A crystallizer is a key part in continuous casting equipment and is the heart of the continuous casting equipment. Detecting and controlling of a crystallizer liquid level are the premise of normal working of the crystallizer, the double-sensor molten steel liquid level measuring equipment has better measuring effect on a large continuous casting machine plate blank crystallizer than that of a single-sensor detecting mode, the double sensors are arranged on the two sides of a crystallizer water opening, a symmetrical liquid level collecting mode is used, influence on the liquid level from false liquid fluctuation can be well removed, the shortcomings that a traditional single sensor is small in detecting range and poor in single-point measuring stability are overcome, and the shortcoming of influence on the liquid level from electro-magnetic testing is overcome.

Description

technical field [0001] The invention relates to continuous casting equipment, in particular to a dual-sensor molten steel liquid level measuring equipment. Background technique [0002] Generally speaking, the mold is the most critical part of the continuous casting equipment, and it is also the heart of the continuous casting equipment. The detection and control of the liquid level by the mold is the premise to ensure the normal operation of the mold. [0003] At present, the molten steel level measurement system of continuous casting machine has a very wide range of applications in the metallurgical industry. It can be roughly divided into the following two categories: eddy current molten steel level measurement system and electromagnetic molten steel level measurement system. [0004] The eddy-current molten steel level measurement system is installed at the nozzle end above the crystallizer, which has no effect on electromagnetic stirring. However, this system uses a s...
