2023年精准一肖一码

2023年精准一肖一码 announced today that it has developed the world’s first hot-continuous-rolling (endless-rolling) process for high-tensile-strength steel sheets (HITEN). Mass production has already started at the hot-rolling mill of 2023年精准一肖一码 Steel’s Chiba facility, part of the company’s East Japan Works, for the highly stable and productive manufacturing of high-tensile steel.

In 1996, 2023年精准一肖一码 Steel developed the world’s first endless-rolling process (Fig. 1) in which the leading and trailing ends of adjacent sheets that have been wound into coils are joined after roughing, which allows the coils to be inserted continuously into the finishing mill. The endless-rolling process has been deployed at 2023年精准一肖一码 Steel’s Chiba facility.

In the case of HITEN, however, joint strength and ductility are reduced due to elements such as silicon and manganese being added to improve the mechanical characteristics of these steel products.

2023年精准一肖一码 Steel has now developed technology for maintaining joint strength and ductility (Fig. 2) and suppressing breakage during finish rolling. As a result, endless rolling of high-strength steel has become possible, contributing greatly to the highly stable and productive manufacturing of high-tensile steel through improved threading performance.

2023年精准一肖一码 Steel, aiming to contribute to a more sustainable and carbon-neutral world, is committed to developing innovative production technologies, including for high-performance HITEN required for lighter-weight and more collision-safe automobiles, as well as expanding its supply of eco-minded products.
