Device and method for measuring coaxiality of trunnions of converter backing ring

Abstract

The invention provides a device and method for measuring coaxiality of trunnions of a converter backing ring, which belong to an online measuring and adjusting device and method for detecting transverse offset between two parallel shafts, in particular the coaxiality of the trunnions in the converter backing ring manufacturing process. The device comprises two trunnions and two fan-shaped bodies, wherein the two trunnions are provided with backing rings; the device is characterized in that a transmission bracket and a laser are arranged at the outer end of the trunnion on the transmission side and a transmission target bracket and a target are arranged at the inner end of the trunnion on the transmission side; an inner receiving target brackets, outer receiving target brackets and targets are arranged at inner and outer ends of the trunnion on the free side; and the measurement is carried out by a method for arranging the brackets, mounting the laser, debugging the laser, measuring the free trunnion, adjusting the free trunnion, observing the welding, measuring after welding and processing data. The device and method for measuring the coaxiality of the trunnions of the converter backing ring, provided by the invention, have the advantages of novel design, simple structure, simplicity and convenience in operation and accurate and timely measurement; a problem that the coaxiality of the trunnions is hard to measure inthe manufacturing process is solved; the machining efficiency is increased; the accuracy of the coaxiality is enhanced; the machining quality is improved; the consumption is reduced; the service life of the backing ring is prolonged; and steelmaking smoothness is guaranteed.

Description

technical field [0001] The invention belongs to the detection of lateral offset between two parallel shafts by an optical method, and in particular relates to an on-line measurement device and method for trunnion coaxiality in the manufacturing process of a converter support ring. Background technique [0002] The converter support ring is an important bearing and transmission part of the converter. During the working process, in addition to bearing the static load of the furnace body, molten steel and accessories of the furnace body and transmitting the tilting moment, it also bears the dynamic load generated by frequent starting and braking, as well as the dynamic load from the furnace body, molten steel tank, smoke hood and spray The heat load generated by the thermal radiation of the splash. Therefore, the manufacturing quality of the support ring determines the service life of the converter, and the coaxiality of the two trunnions is an important technical quality inde...
