Description
技术领域technical field
本实用新型涉及一种浸入式水口在线深度测量装置。The utility model relates to an online depth measuring device of an immersion nozzle.
背景技术Background technique
炼钢连铸工段中间包开包时，需在线测量浸入式水口插入结晶器铜管液面的深度，测量时如果插入深度浅，浇铸过程中易造成结晶器铜管液面卷渣；而插入深度深，保护渣化渣效果差，会影响铸坯表面润滑而导致生产事故，甚至于当插入深度超过浸入式水口渣线区时会导致浸入式水口穿孔，造成铸坯报废。如图1所示为传统的浸入式水口插入深度测量装置，测量时，在中间包烘烤前，先测量出浸入式水口底部出口端距离中间包底板之间的长度B，中包开浇后再通过Φ6mm的长引流管测量出中间包底板到结晶器铜管液面的长度A，则浸入式水口在线插入深度为B-A。但由于中间包烘烤后受热、中间包装满钢水后受钢水静压力影响，中间包底板出现变形后导致在线测量插入深度产生偏差，易出现实际测量A变小，使得最终测量所得的插入深度变大，一旦当插入深度超过浸入式水口渣线区时，出现侵蚀穿孔现象。When unpacking the tundish in the steelmaking and continuous casting section, it is necessary to measure the depth of the submerged nozzle inserted into the liquid surface of the copper tube of the crystallizer on-line. The depth is deep, and the effect of mold slag melting is poor, which will affect the surface lubrication of the slab and cause production accidents. Even when the insertion depth exceeds the slag line area of the submerged nozzle, the submerged nozzle will be perforated and the slab will be scrapped. As shown in Figure 1, it is a traditional immersion nozzle insertion depth measuring device. When measuring, before the tundish is baked, first measure the length B between the outlet end of the immersion nozzle bottom and the tundish bottom plate. After the tundish is poured Then measure the length A from the bottom plate of the tundish to the liquid surface of the copper tube of the crystallizer through the long drainage tube of Φ6mm, and then the online insertion depth of the submerged nozzle is B-A. However, due to the heating of the tundish after baking and the influence of the static pressure of molten steel after the tundish is filled with molten steel, the deformation of the bottom plate of the tundish leads to deviations in the online measurement of the insertion depth, and the actual measurement A is likely to become smaller, making the insertion depth obtained in the final measurement. Once the insertion depth exceeds the slag line area of the submerged nozzle, erosion and perforation will occur.
