Title: Yasuhiko Daimon: Innovator in Seamless Steel Pipe Production
Introduction
Yasuhiko Daimon is a prominent inventor based in Tokyo, Japan. He has made significant contributions to the field of metal processing, particularly in the production of seamless steel pipes. With a total of 3 patents to his name, Daimon continues to push the boundaries of innovation in his industry.
Latest Patents
Daimon's latest patents include a piercing machine and a method for producing seamless metal pipes using this machine. The piercing machine features a plurality of skewed rolls, a plug, a mandrel bar, and an outer surface cooling mechanism. This cooling mechanism is strategically positioned around the mandrel bar to effectively cool the hollow shell as it advances through the cooling zone. The cooling fluid is ejected towards various parts of the hollow shell to ensure optimal cooling.
The production method for seamless steel pipes involves several steps, including heating an Nb-containing steel material to temperatures between 800 to 1030°C. The process utilizes piercing-rolling or elongation-rolling techniques to create a hollow shell. Following this, a cooling step is implemented to rapidly reduce the outer surface temperature of the hollow shell portion to between 700 to 1000°C within 15 seconds after passing through the rolling mill.
