OverviewrnrnThe taper of the narrow face of the mold has an important influence on the quality of the casting billet. Excessive taper will cause the mold to squeeze the billet shell, and a small taper will increase the air gap. With the continuous increase of the requirements of the casting billets’ quality and the continuous introduction of high-precision molds, the current taper measuring instrument in the domestic market generally have low measurement accuracy and complex measurement methods, which restrict production development.rnrnThe new-generation taper measuring instrument developed by Wuhan CenterRise M&C Engineering Co., Ltd. adopts imported high-precision inclination sensor, combined with ultra-low power consumption processor, which can quickly and accurately measure the actual taper value of the narrow copper plate of the mold. The instrument is fully functional, easy to use and suitable for slab molds of various lengths.rnrnMost of the current slab molds are single-taper, a narrow flat copper plate. The taper value required for production can be achieved by adjusting the angle between the narrow copper plate and the direction of gravity. The taper measuring instrument directly measures the angle between the narrow copper plate and the direction of gravity. According to habits and production needs, the angle is converted into the value of one-sided shrinkage of the upper and lower ports.rnrn rnrnThe main featuresrnrn1.
