Title:
HEAT TREATMENT PRODUCTION LINE WITHOUT CHARGING BASKET
Document Type and Number:
WIPO Patent Application WO/2020/168689
Kind Code:
A1
Abstract:
Disclosed is a heat treatment production line without charging basket, comprising a smelting furnace feeding mechanism (1), a smelting furnace accumulating mechanism (2), a smelting furnace (3), a quenching mechanism (4), a water pouring mechanism (5), an ageing furnace (6), an ageing furnace accumulating mechanism (7) and an ageing furnace discharging mechanism (8) which are successively connected. Multiple layers of roller bars (9) which are longitudinally arranged at intervals are correspondingly disposed in the interiors of the smelting furnace (3) and the ageing furnace (6); a combustion circulating mechanism used for heating is provided inside the smelting furnace; and a waste heating mechanism is disposed outside the smelting furnace (3) for connecting with the ageing furnace (6). The heat treatment production line changes the traditional heat treatment mode, cancels the charging basket and reduces manual discharging, thereby realizing the automation of heat treatment production process. Direct combustion in the furnace is adopted so as to improve the thermal efficiency. A waste heating mechanism is configured to make a secondary utilization of the waste heat, so as to reduce the combustion energy of the ageing furnace.
