The invention provides a lubricating oil barreled additive heating device and system. The system comprises a heating box, accessory equipment, a control system and a steam control valve bank. The system can complete the automatic heating process of additives just by putting lubricating oil barreled additives into a box body; the heating time can be set; and the functions of high-temperature warning and high-temperature interlocking cut-off of heating steam are achieved. By adopting the lubricating oil barreled additive heating device and system, the problem of heating of lubricating oil barreled additives is solved. The device is simple, operation is easy, the temperature rising speed is high, and the temperature is uniform and controllable. Accordingly, the efficiency is improved, and the production cost is lowered.
