Large scale furnace body steel structure steel skeleton of natural gas trolley furnace is welded by large steel, steel plate, etc, with high strength bolts and bolts. In the design, the influence of thermal expansion is fully considered. In any case, the furnace body will not be deformed due to the expansion and contraction.

 

The refractory fibre composite structure of the furnace body, the weight is only a brick furnace 1/20, but can save 25 ~ 30%, the lining has characteristics of convenient installation, short construction time, service life than brick furnace. Fiber furnace wall heating up fast, 1.5 hours to reach the temperature of the air heater can be achieved; fiber furnace body heat storage is less, in the district to mediate the temperature, the response rate is faster than the brick body. And when the fault shutdown after a relatively short period of time can be ruled out fault; refractory fiber furnace wall thermal shock stability, even when subjected to mechanical collision damage, only local repair, and does not require the oven. Because the lining of aluminum silicate fiber, small thermal conductivity, low density material, so the furnace wall thickness is only half of the brick wall, gas furnace body skeleton is car light. Refractory fiber module has no obvious gap affect the normal performance in the process of using, design and material lining according to the normal service life of not less than 10 years to consider.

 

Natural gas furnace trolley trolley furnace belongs to super heavy truck wheels, put forward higher requirements on the vehicle beam, beam furnace; heavy load furnace composed of high strength car wheels, large steel structure Fishbelly / longitudinal beam of the frame, iron frame and the high strength refractory insulation materials, design and material selection for the bogie frame according to normal the use of deformation conditions in 5 years does not affect the car out, sealing, considering partial load. The car on both sides of the large furnace refractory brick shaped castable (form a labyrinth structure and forming the furnace body on both sides of fiber castable block, and the middle of the car) than the furnace castable is low, not only the unit pressure, impact resistance, and long service life, once damaged, the replacement is convenient. Natural gas furnace trolley electric bicycle, electric motor, spiral bevel gear reducer, brake three-in-one, directly installed in the driving wheel group, convenient installation and maintenance, through the automatic version of the power supply to the car body. The walking speed of the furnace is about 6 to 8m/min.
