Polycrystalline mullite fiber cotton blocks enhance radiation heat transfer and reduce heat loss

1. Improve the service life of rotary kiln and burner bricks

Manufacturer of polycrystalline mullite fiber cotton block: After pasting polycrystalline mullite fibers on the inner surface of the rotary kiln, the direct flushing of the furnace gas on the rotary kiln is improved, and the quenching and heating of the rotary kiln are cached. The temperature controlled by the rotary kiln can be reduced by 70-100 degree , effectively preventing the cracking and detachment of refractory materials. Due to the characteristics of thermal storage ignition technology, the gas after thermal storage has a significant destructive effect on the burner brick. The selection of pre formed technology or on-site pouring technology for brick firing makes maintenance and replacement difficult. If polycrystalline mullite fibers are pasted on the surface of the burner brick, it will reduce the flushing of the flame on the burner brick and effectively protect it. After self pasting fibers, the burner brick only shows slight cracks after being applied for 2 years, and its service life can be extended to more than 4 years.

2. Meningkatkan radiatif haba pemindahan dan mengurangkan haba kehilangan

Polycrystalline mullite fiber cotton block manufacturer: The heat transfer method in the high-temperature zone of the heating furnace is mainly radiation heat transfer, and radiation source heat exchangers are carried out between the furnace gas, furnace mouth, and the heated steel. The luminosity of the furnace mouth is generally {{}}.8. The luminosity of polycrystalline mullite fibers is 0.95. Under the same heating conditions, the increase in luminosity after pasting polycrystalline mullite fibers increases the radiation heat in the furnace, thereby improving the heating speed of steel and the heating level of the furnace.

Pengilang of polycrystalline mullite fiber cotton blocks: Based on the measurement of the ambient temperature at various points after repair and the next maintenance and upkeep, the dropping status of polycrystalline mullite fibers was checked. under the same temperature control conditions, after sticking polycrystalline mullite fibers, the average surface temperature of the furnace wall decreased by 34. 8 degree , reducing the heat discharge of the furnace wall and improving the thermal efficiency of the furnace. At the same time, with the improvement of the office environment, it has added convenience to the supervision, inspection, and operation of workers.

3. Reduce thermal inersia, improve efficiency and heating quality

Polycrystalline mullite fiber cotton block manufacturer: The armpit of the continuous high temperature section of the heating furnace is made of refractory casting material, which can be compacted with plastic in the rotary kiln. The refractory material used has a relatively high thermal conductivity, and the burner adopts a single thermal storage combustion method. On the one hand, this depends on the existence of a certain lag effect in the heating furnace during temperature increase and decrease. On the other hand, polycrystalline mullite fibers can reduce the thermal conductivity and thermal conductivity of the furnace, accelerate the temperature increase and decrease, and reduce thermal inertia, which is beneficial for increasing production. Due to the reduction in heating time of the raw material, the air oxidation and carburization of the raw material in the heating furnace are reduced, ensuring the heating quality of the raw material.
