The deep well resistance furnace is mainly used for hanging and heating type workpieces such as long shafts, connecting rods, and rigging. The temperature is uniform during heating and the deformation of the workpiece is small. Adopting load-bearing refractory brick structure.
The structure of a deep well resistance furnace mainly consists of a furnace body, a furnace cover, heating elements, and a temperature control system.
The outer shell of the furnace body is welded from steel sections and steel plates, and the furnace lining adopts a brick type load-bearing furnace. Long fiber felt is used as insulation material. The equipment is made into various specifications according to the furnace body, and a certain amount of compression is left during the processing to ensure that each ceramic fiber block expands in different directions after the module is built, so that the modules are squeezed into a seamless whole, achieving good heat storage effect. Moreover, this product is easy and fast to construct, and can be directly fixed on the stainless steel anchor round nails of the furnace shell steel plate. Compared with other products, the advantages are low thermal conductivity, low heat capacity, excellent corrosion resistance, excellent thermal stability, thermal shock resistance, insulation, and the anchor is set on the cold surface of the furnace body, which improves the high temperature resistance strength of the fiber.
The spiral heating element is fixed to the furnace lining with high aluminum nails.
The opening and closing of the furnace cover are both completed by an electric motor mechanism. When the furnace cover needs to be opened, simply press the button, and the furnace cover can be opened to both sides; To close the furnace cover, simply press the button and the cover will close towards the center. At the opening and closing position, there is a limit switch. When in place, the limit switch automatically cuts off the power supply of the electric fan to avoid danger during operation.
According to the special heating characteristics of the workpiece, there is a fixed heavy-duty steel structure frame on the moving bracket of the furnace cover of the deep well resistance furnace. After hanging the workpiece into the furnace, the bracket is placed on the steel structure frame.
The size is customized according to user requirements, with an energy-saving effect of 30% and testing exceeding the national standard.
