Title: Noboru Komatsubara: Innovator in Refractory Materials
Introduction
Noboru Komatsubara is a notable inventor based in Kurashiki, Japan. He has made significant contributions to the field of refractory materials, holding 2 patents that showcase his innovative approach to material science.
Latest Patents
One of his latest patents is for a graphite-containing monolithic refractory material. This material comprises at least one component selected from alumina and alumina-magnesia spinel, which are divided into selected particle size regions, artificial graphite having a selected average particle size, and pitch powder. The refractory material may optionally include a selected amount of silicon carbide with a specific average particle size. This innovative material exhibits excellent casting workability at a low moisture content, along with outstanding corrosion resistance and spalling resistance. It is particularly suitable as a casting monolithic refractory material for lining a torpedo ladle car.
Another significant patent involves a repairing material for the bricks of the carbonizing chamber in a coke oven. This repairing material is obtained by compounding mortar as a main component with a powder comprising 70-100 wt. % of a Co compound, Ni compound, and/or Al compound, along with 0-30 wt. % of at least one compound selected from among the compounds of Ca, Mg, Zn, Sr, Ba, Fe, V, Pb, Cu, and Ti, and a liquid formed of water, B, P, and at least one member selected from among Si, Na, and K. The method for repairing includes hot applying the repairing material to portions of the bricks of the carbonizing chamber in the coke oven that require repair.
