The chamber-type electrically heated tempering line consists of one electrically heated chamber-type solid solution furnace, one electrically heated chamber-type aging furnace, two quenching tanks with cooling, circulating, and stirring systems, and one heat-treatment charging and reclaiming machine and charging and reclaiming pedestal. The chamber furnace is configured in accordance with AMS2750 and RRP54000 standards and meets the requirements of Napcad system. The maximum operating temperature of the solid solution furnace is 1200℃, and the homogeneity of the effective zone is ≤10℃; the maximum operating temperature of the aging furnace is 750℃, and the homogeneity of the effective zone is ≤6℃, with hot air stirring system. The automatic loading and unloading machine can realize the self-movement of workpieces under any process among multiple stations such as material table-solid solution furnace-ageing furnace-quenching tank. The main products of this tempering line are blade flat steel, precipitation hardening stainless steel, high temperature alloy, etc.; the main specifications are 50~100×90~200×2500~4000, φ90~350×2500~4000, φ50~80×2500~4000, with an annual design capacity of 1500 tons.
