A converter sub-lance centering device and centering method

Abstract

The invention provides a converter sublance centering device. The converter sublance centering device comprises a conical centering cylinder, supporting frames, hoisting steel ropes, centering adjusting bolts A, centering adjusting bolts B, a fixing frame, a fine adjustment frame, a balancing weight and a base. One end of each hoisting steel rope is connected with a balancing weight cylinder, and the other end of each hoisting steel rope is connected with the corresponding centering adjusting bolt B. The centering adjusting bolts B are in screw joint with the supporting frames. The balancing weight is fixedly arranged at the lower end of the balancing weight cylinder, the fixing frame is fixedly arranged at the upper end of the balancing weight cylinder, and the fine adjustment frame is fixedly arranged on the periphery of the conical centering cylinder. Bolt holes are formed in the fixing frame, long bolt holes are formed in the fine adjustment frame, the fine adjustment frame is in lap joint to the fixing frame, and the fine adjustment frame and the fixing frame are connected through the centering adjusting bolts A. The base is arranged above the position where a probe is inserted into a mechanical hand, and the supporting frames are fixedly arranged on the base. The converter sublance centering device is simple in technical scheme and easy to implement, adjust and control, can guarantee the construction quality of sublance centering adjustment, can also improve the production efficiency, saves the production cost and guarantees stable operation of production.

Description

technical field [0001] The invention relates to the field of metallurgical machinery, in particular to a centering device and a centering method for sub-lances in converter production. Background technique [0002] As the main equipment of automatic steelmaking, converter sublance plays a very important role in modern steelmaking plants. During the smelting process, the sub-lance equipment provides an effective measurement tool for the converter, and the sub-lance can be used to obtain various information about the converter melt pool without interrupting the blowing or turning down the furnace. The sub-lance centering device is the main device for loading and unloading the test probe of the sub-lance. The quality of the sub-lance centering device directly determines the operation rate of the sub-lance system of the converter and the success or failure of the converter's automatic steelmaking.
