英国ｌａｎｄ红外技术公司开发出一种在连续退火期间测量钢及其他光亮金属带材温度技术 ,且成本低廉 ,目前英国、日本和北欧国家均已引进。该法是将ＬａｎｄＳｙｓｔｅｍ 4红外辐射温度仪对准带材与辊子的接触点———楔口或辊缝。此处热能常因在带材和辊子之间经过多次反射而 Land infrared technology company of the United Kingdom has developed a technology for measuring the temperature of steel and other bright metal strip during continuous annealing at a low cost and is currently being introduced in the United Kingdom, Japan and the Nordic countries. The law is LandSystem 4 infrared radiation temperature meter aligned with the roller contact point --- wedge mouth or roll gap. Thermal energy here is often due to multiple reflections between the strip and the roll
