A vacuum furnace reduction process with a belt outfeed

Abstract

A kind of vacuum furnace reduction process with tray out loading, the process makes several square graphite plates, evenly and densely sets several air holes on the graphite plate, and makes several high-temperature-resistant stainless steel trays;At least two layers of graphite columns are stacked in the stainless steel tray, the graphite plate is horizontally laid on the transfer trolley, then the stainless steel tray loaded with graphite column is stacked layer by layer on the surface of the graphite plate, and the transfer trolley is driven to send the stacked graphite column into the oven for low-temperature baking;After low-temperature baking, the graphite column is taken out as a whole by the transfer trolley and transferred to the vacuum furnace for vacuum baking;The process does not need to place the graphite plate layer by layer, removes the multi-layer graphite plate structure, greatly increases the effective utilization space of the vacuum furnace and the oven, and the number of graphite columns loaded per furnace can be increased by more than 30%, when discharging, it does not need to be loaded into the tray manually, but directly put the tray loaded with graphite column into the turnover box, reduces the rate of rotten block, effectively improves the baking efficiency and yield.
