In the metallurgical industry, by the ladle car to undertake ladle refining operations, ladle car in the production process with the process requirements to constantly move to different positions,      such as refining position, wire feeding position, bale hoisting position and so on. In the process of   refining, have higher requirements to the position of the ladle car, in the past using close reflection for the position limit position, because of the refining furnace under the reality conditions, the spray of molten steel in the process of refining the four splash, splash spray of molten steel to make the   circuit and the limit of fire, damage, such as wiring short circuit, open circuit, lead to the  failure of  positioning and orientation is not accurate, The ladle car can not stop at the predetermined            position, thus causing the phenomenon of slipping, resulting in vehicle collision or cable pulling off  accidents, affecting refining production, and even causing the injury of personnel and equipment,so the  distance  laser  sensor with high measurement accuracy and convenient maintenance is            adopted.The application of distance  laser  sensor is very helpful for accurate positioning of ladle    car.

     MIDEKER pulse laser ranging sensor can better solve this application pain point, and has          applied for a patent (patent name: a pulse sensor for ladle car positioning, Patent Number: CN202021912999.4), MIDEKER sensors are connected to the control network through the PROFINET          interface of PLC to realize automatic control of ladle car process operation.

     MIDEKER sensor has the advantage of adapting to complex environment and non-contact.      After a long time of development, the technology has been mature and the measurement accuracy has been greatly improved. The distance ranging positioning of The Steel refining furnace ladle car has been transformed into a laser range finder through the near-range reflection limit. It is not only light in weight, small in size, easy to install and adjust, but also stable in work and strong in             anti-interference ability, which can eliminate vehicle collision and vehicle cable pulling off accidents caused by positioning failure, greatly reduce the accident rate of refined steel chartering car, and    ensure the normal production rhythm and smelting quality of refining.
