It can be used in the aerospace and aviation aircraft manufacturing industry, and the electric furnace microcomputer program temperature control cabinet realizes high-precision process curve automatic temperature control.
- The aluminum alloy pit aging furnace shell is made of steel plate and section steel, and the inner surface of the furnace cover is made of stainless steel plate. The lining is made of ultra-lightweight and energy-saving microbead refractory insulation brick. The lining and the furnace shell are sandwiched with aluminum silicate ultra-long fiber cotton insulation, and the gap is filled with the expansion heat preservation powder. It belongs to the typical energy-saving furnace lining structure, saving 30%-40%. The electric resistance wire is spirally mounted on the wire brick of the furnace by a 0Cr25Al5 high resistance alloy wire. A stainless steel loading basket is placed inside the hearth. The furnace cover is lifted by a manual mast, and the large furnace cover is lifted by an electric transmission. In order to uniformly heat the workpiece, a hot air circulation fan made of a heat-resistant stainless steel shaft and a fan blade is installed on the furnace cover. During the heating process, the hot air is circulated up and down in the aluminum alloy aging furnace to ensure uniform heating of the workpiece. In order to ensure the safety of operation, a limit switch is installed near the lifting mechanism. This switch is interlocked with the power supply of the aluminum alloy aging furnace control cabinet, and the power is turned on when the furnace cover is closed (working). When the furnace cover is opened, the limit switch cuts off the control power, so the power of the heating element is cut off at the same time to ensure safe operation. The aluminum alloy pit aging furnace is equipped with automatic temperature control cabinet and thermocouple.
