Sumitomo Metal Industries Ltd has developed temperature measuring technology for the cooling banks of the hot strip process as well as high precision control technology based on the use of the former technology. This has enabled the company to manufacture better quality high-tensile strength hot strip in a more stable manner. The quality and properties of high-tensile strength hot strips depend on temperature control during the cooling stage right after being rolled out. To ensure better control, the temperature needs to be measured more accurately. Sumitomo Metals subsequently developed a new technology to measure the temperature more accurately and improve temperature control precision when cooling strip. As a result, high tensile hot strip detect length beyond a tolerable margin of error in the measuring temperature before the coiler were almost halved, enabling manufacturing of high-tensile strength hot strip with more stable quality.
