AI Technical Summary
Technical Problem
The traditional loading and unloading methods of existing vacuum furnaces are inefficient, have low graphite column loading capacity, high fuel costs, are cumbersome to operate, and are prone to lumps breaking off.
Method used
The process employs a vacuum furnace with tray loading, using stainless steel trays and a strut-type lifting forklift. Graphite columns are stacked layer by layer on the stainless steel trays, and the strut-type lifting forklift is used to efficiently feed and remove the graphite columns, simplifying the operation process.
Benefits of technology
It improves the effective use of space and roasting efficiency of the vacuum furnace, reduces the rate of broken pieces, increases the efficiency of loading and unloading the furnace, and reduces fuel costs.

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.
