Title: Motoyasu Yaji: Innovator in Refractory Coating and Continuous Casting Technology

Introduction

Motoyasu Yaji is a notable inventor based in Chiba, Japan. He has made significant contributions to the fields of refractory coating and continuous casting technology. With a total of three patents to his name, Yaji's work has had a considerable impact on industrial processes.

Latest Patents

Yaji's latest patents include a method and apparatus for spray coating of refractory material. This innovative technique utilizes a mixture of refractory material and a combustible metal powder. The particle size of the metal in the mixture is carefully selected to ensure safe treatment while being small enough for transport via gas flow. A non-combustible gas or fuel gas serves as the carrier gas for this mixture. The process involves discharging a fuel gas and a combustion-assisting gas toward the surface section to create a combustion frame. The refractory material is then discharged into this frame, enhancing the efficiency of the coating process. Another significant patent is a method of controlling continuous casting equipment. This method aims to prevent breakouts or cracks in the slab of continuous casting equipment by measuring heat flux waveforms or values at various positions of the mold. When deviations from target values are detected, adjustments are made to the pouring rate and other parameters to maintain optimal conditions.
