Split type mobile furnace, split type mobile furnace factory

Description :

　　Overview (This furnace mainly relies on the movement of the furnace body to complete its work)

　　The RT3 full fiber series trolley type resistance furnace (hereinafter referred to as the electric furnace) is mainly used for heat treatment of general metal or alloy parts at temperatures lower than the rated temperature.

　　2、 Usage conditions

　　1. Indoor use.

　　2. The ambient temperature is within the range of -5 ℃ to 40 ℃.

　　3. The monthly average relative humidity in the usage area shall not exceed 85%.

　　4. There are no conductive dust, explosive gases, or corrosive gases that can seriously damage metals and insulation around.

　　5. No obvious vibration or turbulence

　　3、 Structure Introduction

　　The shell of this series of electric furnaces is welded from steel plates and steel sections, and the trolley is welded from steel sections and steel plates. The trolley reduces heat radiation and convection losses by soft contact with the furnace lining, effectively ensuring the sealing of the furnace body.

　　Lining: The furnace body of this furnace is made of full fiber, and the fibers are made into modules according to the size of the furnace. The fibers are compressed into blocks for on-site cotton construction. The fixing method is to evenly thread through the block shaped fiber cotton with hooks and nails, then hook the threads with hooks and nails, tighten them, and weld them to the furnace body. The pressure resistant part of the trolley is constructed with high alumina bricks, and the lower part is insulated with insulation bricks.

　　The lifting of the furnace door is achieved by rollers on the guide rail It is achieved by rolling up and down, and adopts advanced spring compression mechanism in China to seal the furnace door. This not only ensures the sealing between the furnace door fibers and the furnace body fibers when closed, but also ensures that the fibers will not be damaged by friction during the opening and closing process. The power of the furnace door and trolley is provided by an electric motor through a cycloidal pinwheel reducer, and has controllable braking function.

　　The various activity mechanisms of the electric furnace adopt chain control, that is, when the furnace door is opened, the power supply to the heating element is automatically cut off, and at the same time, the power supply for the trolley to travel is restored; After the furnace door is closed, the power supply to the trolley walking motor is automatically cut off, and the power supply to the heating element is restored to prevent accidents caused by misoperation.

　　The heating element is made of high-temperature resistance alloy wire wound into strips and spirals, which are hung on the furnace side and placed on the wire support brick of the trolley, and fixed with high aluminum porcelain nails and socket support bricks to prevent detachment.

　　The trolley is equipped with a pressure resistant and high-temperature resistant cast steel furnace bottom plate for carrying workpieces. In order to prevent the oxide scale generated after heating the workpiece from passing throughIndustrial electric furnaceThe gap between the furnace bottom plate falls around the heating element, causing damage to the heating element. Therefore, the contact between the furnace bottom plate and the furnace body adopts an insertion type contact.

　　Due to the relative entry and exit between the furnace body and the furnace truck, considering the expansion after heating, this part adopts a fiber cotton soft contact sealing structure. The characteristic of this sealing structure is reliable sealing and easy maintenance.

　　The entire electric furnace is temperature controlled by zones, with one thermocouple used for temperature control and detection in each zone. The control method is programmable PID automatic adjustment, and a thyristor zero crossing trigger circuit is used for temperature adjustment. And adopt contactor protection control. The intelligent digital temperature controller can be used for temperature setting, correction, digital display, and control. If Dahua instruments are used, temperature can be printed and recorded, and sound and light alarms can be triggered after overheating, but not controlled.
