Description

Technical Field

[0001] The utility model relates to the technical field of steel billet cutting seam width measurement, in particular to a steel billet cutting seam width measurement device. Background Art

[0002] Currently, cutting is used for cutting continuous casting billets to fixed lengths. The detection of the cutting seam is particularly important. It is necessary to detect whether the cutting seam is within the technical requirements. If the actual billet cutting gap is too large, it will reduce the billet forming rate and increase the steel material consumption. The cause should be checked immediately.

[0003] However, there are still some disadvantages: the existing technology generally uses a vernier caliper to measure the cutting gap. However, when using a vernier caliper, the hand is close to the cutting gap, which reduces the safety of the worker's hand and easily causes burns. Therefore, we propose a steel billet cutting gap width measuring device to solve this problem. Utility Model Content
