Title:
METHOD FOR PRODUCING CARBIDE, AND EQUIPMENT FOR PRODUCING CARBIDE
Document Type and Number:
WIPO Patent Application WO/2021/200520
Kind Code:
A1
Abstract:
Provided is a method for producing a carbide, the method involving using a rotating retort furnace including a rotating retort, a combustion chamber for heating the surface of the retort using combustion gas, and an exhaust means that exhausts the gas generated inside the retort into the combustion chamber to indirectly heat a processing material while causing the same to move within the retort, thereby generating a carbide, the method for producing a carbide including a step in which a component at or below a prescribed grain diameter is separated from the processing material before the processing material is charged into the retort.
