The uniformity of tap time and the time of slag exposure are important indicators to measure whether the taphole of the blast furnace is operating normally. Automatic identification is the basis of enterprise production automation and management informatization.
目前炼铁厂普遍采用的记录开铁口、堵铁口时间和见渣时间的方式为人工判断,然后在电脑上输入相应的时间。由于高炉上的工作节奏快,事情多,经常不能在第一时间记录,导致记录的时间不准等问题。At present, the method commonly used in ironmaking plants to record the time of opening, plugging and slag viewing is manual judgment, and then input the corresponding time on the computer. Due to the fast pace of work on the blast furnace and many things, it is often impossible to record at the first time, resulting in inaccurate recording time and other problems.

Computer vision is to replace the visual organ with various imaging systems as input information. The computer replaces the brain to complete the processing and interpretation. The ultimate goal of computer vision is to study the ability of computers to perceive and understand the world like humans, with autonomous environmental adaptation capabilities. At present, there are more and more application scenarios of computer vision in iron and steel enterprises, which reduces the labor cost of enterprises to varying degrees and ensures the timeliness of information. However, the traditional image technology needs to design a large number of artificial features. In a complex production environment, some features may be blocked by certain items and machinery, resulting in a low recognition rate. How to overcome the shortcomings of the existing technology is currently in the field of metallurgical automation technology. Urgent problem to be solved.
