Description

Special device for online measurement of continuous casting billet height Wen Duanmian Technical Field The utility model belongs to the field of metallurgical continuous casting process equipment, and particularly relates to a special device for online measurement of a high-temperature section size of a continuous casting billet. Background In metallurgical continuous casting processes, accurate measurement of the cross-sectional dimensions of a continuous casting billet is critical to ensuring product quality. Continuous casting is a continuous high temperature process in which the surface temperature of the strand after leaving the mould is generally above 1000 ℃. After passing through the withdrawal and straightening machine, the temperature is 800-900 ℃, and personnel need to confirm whether the section size of the billet meets the requirement. In the prior art, a steel plate ruler is often adopted to measure the section of a steel billet after cutting. The measuring mode is based on a simple length comparison principle, the steel plate ruler is manually held, the ruler body is aligned with the edge of the section of the steel billet, and the scale value is read to obtain the size information. Therefore, the existing measurement scheme mainly relies on an operator to use a steel plate ruler, after a steel billet is cut, the steel plate ruler is moved to a cooling bed, the operator lies prone on the steel billet, measures the steel plate ruler close to the edge of a section, and only needs a measurement tool such as the steel plate ruler, but in actual operation, the measurement process is completely dependent on manual alignment and reading, and the measurement process lacks accurate positioning and guiding structures. Accordingly, the prior art has the following problems: 1. The problem of low measurement accuracy is that when the manual hand-held steel plate ruler is used for measuring, accurate alignment of the ruler body and the edge of the section of the steel billet is difficult to ensure, and the reading is easily influenced by factors such as visual angles, shaking and the like, so that the measurement deviation is large, and the high-accuracy production requirement cannot be met. 2. The potential safety hazard is high, the temperature of the cut steel billet is extremely high, operators need to lie prone on the steel billet for measurement, the close-range contact with the high-temperature area is extremely easy to cause scalding accidents, and meanwhile, the protector is easy to burn out in a high-temperature environment, so that the personal safety of the operators is seriously threatened. 3. And the measurement hysteresis is that the billet is required to be transported to a cooling bed for cooling after being cut, and then the billet cannot be measured in real time on a cutting site, so that the quality feedback is not timely, the rapid adjustment of the subsequent process parameters is affected, and the production efficiency and the timeliness of product quality control are reduced. Disclosure of utility model The utility model aims to provide a special device for online measurement of a high Wen Duanmian size of a continuous casting billet, which aims to solve the problems of low precision, high hidden danger and hysteresis in the prior art when the high-temperature section size of the continuous casting billet is measured. The utility model adopts the following technical scheme that the special device for online measurement of the high-temperature section size of the continuous casting billet comprises: The lower end of the scale rod is fixedly connected with a lower end buckling rod, and the lower end buckling rod is mutually perpendicular to the trend of the scale rod; The sliding rod is vertically arranged and is parallel to the scale rod, the lower end of the sliding rod is fixedly connected with an upper end buckling rod, and the upper end buckling rod is mutually perpendicular to the trend of the sliding rod; the fixed short pipe is sleeved on the scale rod and is fixedly connected with the scale rod; The sliding sleeve is sleeved on the sliding rod and can slide up and down along the trend of the sliding rod, and the sliding sleeve is fixedly connected with the fixed short pipe through a connecting rod which is horizontally arranged, so that the sliding rod can slide up and down relative to the scale rod; The outer wall of the sliding rod is provided with a mark, and the distance between the mark and the upper end buckling rod is equal to the distance between the zero point on the scale rod and the lower end buckling rod; The steel billet horizontally placed between the upper buckling rod and the lower buckling rod stretches into the steel billet, and then the scale value on the scale rod corresponding to the mark of the sliding rod is read, so that the section size of the steel billet can be obtained.
