Abstract

The invention relates to an oxygen lance position detection encoder verification device and method, and belongs to the technical field of steelmaking. According to the technical schemes, a to-be-verified encoder (1) is connected with one end of a variable frequency motor (3) through a coupler A (2); a standard encoder (5) is connected with the other end of the variable frequency motor (3) through a coupler B (4); a to-be-verified encoder display circuit (6) and a standard encoder display circuit (8) are respectively connected with the to-be-verified encoder (1) and the standard encoder (5) through cables; and a variable frequency motor control circuit (7) is connected with the variable frequency motor (3) through a cable. According to the oxygen lance position detection encoder verification device and method of the invention,whether the encoder has a fault or not and whether detection error is qualified or not are detected by simulating field working operation conditions, so that an oxygen lance position detected by the encoder used on line is ensured to be accurate, and production, safety and environmental protection accidents are avoided. The device is simple in structure, reliable in operation and is convenient to operate.

Description

technical field [0001] The invention relates to an oxygen lance position detection encoder verification device and method, and belongs to the technical field of steelmaking. Background technique [0002] Oxygen lance is the main process equipment in top-blown oxygen converter steelmaking, its performance characteristics directly affect the smelting effect and smelting time, and then affect the quality and output of molten steel. In different stages of blowing, due to the obvious difference in slag composition, metal composition and molten pool temperature, the position of the oxygen lance is also different. Usually an encoder is used to detect the gun position of the oxygen gun in real time. When the encoder fails or the error is large, the position of the oxygen lance is wrong, which will further cause a series of production, safety and environmental protection accidents, such as production stoppage, gun eating, smoking and other accidents. For this reason, it is necessar...
