With the development of mechanization, the car and they are widely used in industrial furnace plays an important role in the production process, pallet car furnace because of its unique way of operation, heat dissipation for desktop furnace is very important, below small make up take you to know the following about the "product features and pallet car furnace furnace cooling method" is introduced.
[What product characteristics do trolley stoves have]
1. The trolley furnace equipment USES all kinds of combustion gases as the medium, and is heated through all kinds of burners, with the temperature of 1200℃.
2, trolley furnace furnace framework by a variety of large and medium-sized steel site combination of welding, the shell seal plate for color steel plate, high aluminum fiber fire-resistant cast silk blanket module for the furnace lining, sealing energy-saving effect is obvious.
3. The frame of the trolley is welded by a variety of large I-beams, channels, angles and thick steel plates.
4. All the wheels of the trolley are driving wheels, and the driving is reliable. The transmission system adopts the "three-in-one" motor - reducer installation mode as shaft installation, which is compact in structure, firm in assembly, flexible in and out, simple in operation and convenient in maintenance.
5, the trolley furnace table car refractory brick structure with high aluminum shaped, and the furnace seal effect is good, high compressive strength. The surface of the trolley is laid with iron for stacking workpieces. All the top plates of the platform are made of cast parts to ensure no deformation and durability of the platform furnace body. The sealing between the furnace car and the furnace lining adopts the automatic pressing structure of electric push rod of fire-resistant fiber sealing block. Side sealing open and close interlock with furnace car in and out.
6, the trolley furnace door adopts high aluminum full-fiber fire-resisting silk blanket and section steel combined frame structure, electric hoist lifting, the furnace door sealing mechanism adopts long and short lever spring automatic pressing CAM mechanism and soft side sealing device. Ensure no friction up and down, relaxed, safe and reliable.
7. The chimney is installed with automatic furnace pressure control and butterfly valve, etc., which can adjust the cooling speed.
8. Trolley furnace heating adopts high-speed burner with both sides of cloth. Continuously proportionally regulated combustion. Actuators to adjust the size of air volume, through the size of the proportional valve to adjust the volume of gas, achieve air-fuel ratio, combustion gas and air has a lower limit, each burner gas pipe is equipped with the control solenoid valve, each burner with complete combustion controller independently, with automatic ignition, flame detection, automatic fire alarm to snuff out. This fully ensures the stability and safety of the combustion temperature control system.
[Heat Dissipation method of trolley furnace]
Reduce the trolley furnace to reduce the heat dissipation of the furnace wall, improve the thermal insulation capacity of the lining material and reduce its heat storage, increase the sealing of the furnace, reduce the heat taken away by the driving parts and the basket, the plate, etc.
1. The effective way to reduce the heat dissipation of trolley furnace is first to reduce the surface area of the furnace.
Other conditions being equal, the heat loss of the furnace is proportional to the surface area of the furnace wall. The outer surface of the cylindrical furnace is nearly 14% smaller than that of the box furnace, and the outer wall temperature is 10℃ lower, which can reduce the heat dissipation of the furnace wall by about 20%, reduce the heat storage of the furnace lining, and reduce the unit energy consumption of the processed workpiece by 7%. Therefore, the current type of periodic and continuous trolley furnace has been changed into a cylinder.
2. The method to reduce the heat storage of furnace lining is to adopt the adiabatic refractory with low mass heat capacity and density.
Ceramic fiber, commonly known as aluminum silicate fiber, is an ideal new energy-saving refractory. Because the thermal conductivity of ceramic fiber is small, in the same furnace and lining size, the same furnace temperature, the furnace wall temperature is much lower than the specific brick and light refractory brick. The heating time of ceramic fiber lining is only 1/5 to 1/6 of that of light brick and clay lining.
When the trolley furnace is often running intermittently, the use of ceramic fiber lining is obviously particularly advantageous. On the one hand, the rapid heating of the furnace shortens the auxiliary time; on the other hand, it greatly reduces heat storage and significantly reduces energy consumption. Using ceramic fiber lining reduces the heating time of empty furnace by one sixth and saves fuel by 50%.
3. For all types of trolley furnaces, the proportion of heat energy required by the basket is 18%~29% for trolley interlayer and material tray.
Therefore, reducing the fixture and the weight of the material tray is of great significance to the efficiency of vehicle lifting. One of the ways to reduce weight is to improve the structure of clamps and trays; The second is a reasonable choice of materials. Practice has proved that it is economical to use high quality heat resistant steel to make fixtures and trays from the perspective of life and energy saving.
The above introduction of "what are the characteristics of the trolley furnace products" and "the heat dissipation method of the trolley furnace" hope to let you understand "the product characteristics of the trolley furnace and the heat dissipation method of the trolley furnace" to bring help.
