CONTINUOUS HYDROGEN FURNACE EQUIPMENT FOR MANUFACTURING DIAMOND TOOL AND HEAT TREATMENT METHOD OF DIAMOND TOOL MATERIAL USING THE SAME

摘要

A continuous hydrogen furnace system for reducing or suppressing dangerousness of explosion generated when hydrogen comes in contact with the oxygen contained in the external air by isolating a hydrogen atmosphere within a furnace core pipe from oxygen contained in external air more reliably, and a heat treatment method using the continuous hydrogen furnace system are provided. In a continuous hydrogen furnace system in which an inlet area(I), a heating area(H) and an outlet area(O) are continuously disposed along a pipeline(10) comprising an inlet pipe(12), a furnace core pipe(14) and an outlet pipe(16), the continuous hydrogen furnace system comprises: a transfer unit(20) for transferring a treatment object through the pipeline; a heating unit(50) formed on the periphery of the furnace core pipe to heat the treatment object transferred into the furnace core pipe; a gas supply unit(60) for blowing hydrogen gas into the pipeline to create a hydrogen atmosphere within the pipeline; and gas curtain units(70a,70b) for forming a gas curtain in the inlet pipe and the outlet pipe to isolate the hydrogen atmosphere within the pipeline from oxygen of the outer side of the pipeline.
