According to statistics, the market holdings of cold rolling tube mills have reached more than 6,000 sets, but they are basically in the current situation of low production efficiency, slow rolling speed and low product precision. With the market orientation and application scenarios, the requirements for product specifications (increased diameter-wall specific gravity), product precision (roundness, straightness, surface finish) and product performance (nickel-based alloys, duplex stainless steel, etc.) have increased, and the requirements for the capabilities and functions of traditional equipment have become higher and higher, and they are developing towards extreme, high-speed, intelligent, high-precision and multi-functional aspects, thereby promoting the rapid development of equipment, and then putting forward higher requirements for the structural design, equipment level and manufacturing precision of periodic cold rolling tube mills. Cold rolling tube mills will develop towards extreme, high-speed, intelligent, high-precision and multi-functional aspects.
Seamless pipes are important products. Therefore, in addition to improving the rolling mill, there is a matching intelligent diameter gauge, which is an important instrument for detecting the outer diameter of seamless steel pipes. It plays an important role in realizing automation, intelligence, high speed, and unmanned operation, and is an important part of quality inspection. It has important functions such as online, automation, intelligence, high speed, software system, out-of-tolerance alarm, long-term storage, real-time, and adjustable measurement range, and completes the inspection of various specifications of pipes in production. At present, the online diameter gauge can detect small-sized rolled materials of 0.1mm, and can also complete the inspection of oversized sizes of thousands, tens of thousands of millimeters or even larger. Therefore, basically any size of seamless pipes in production can be inspected by the diameter gauge.
