Product Details
Sintering fan introduction:
The ore used for smelting should be sintered before smelting, sintering machine should be used for sintering, and the sintering furnace needs to use the main exhaust fan and cooling fan, and the centrifugal blower has become the mainstream choice for the main exhaust fan used in the sintering plant with its large air volume and high negative pressure performance characteristics.
Depending on the different sections of the fans in the Sintering system, they are called (taking the sintering ring cooling/cooling fan model of the Hubei Double Sword Blower as an example) : sintering main extraction fans, sintering ring cooling/cooling fans, head/tail dust removal fans, sintering machine ignition aid fans, etc.
As the main smoking machine of sintering machine, the power consumption of sintering blower accounts for more than 50% of the total power consumption of sintering plant. And because the medium transported is sintering flue gas, the dust content is large, therefore, improving efficiency, reducing energy consumption, strengthening wear-resistant measures, and improving service life are still the main technical topics of sintering centrifugal blower.
The air volume of the sintering blower depends on the sintering area of the sintering machine. The pressure depends on the thickness of the sinter layer.
At present, the large-scale sintering machine (has been able to produce 1000 m2 sintering machine) and thick material layer (has reached 700mm), prompting the sintering centrifugal blower to develop in the direction of large air volume and high negative pressure. The maximum flow rate of sintering centrifugal blower is 23000m3/min, the maximum pressure is 19620Pa, and the maximum power is 14500kW.
Due to the limitation of manufacturing process conditions and transportation conditions, the sintering induced draft fan supporting the extra-large sintering machine often adopts the form of double parallel.

Wear resistance measure
Serrated center plate
It can not only improve the airflow distribution at the impeller outlet and reduce GD 2, but also avoid the wash of flue gas on the middle disk
Wear-resistant lining surfacing
The blade is equipped with a replaceable wear-resistant liner (tungsten carbide surfacing on the liner surface)
Replaceable cone
The middle disc is protected from wear by a replaceable cone
Surface strengthening treatment
Surface surfacing, thermal spraying, boriding, laser surface hardening and high frequency hardening, etc
At present, the research on the two-phase flow (solid particles and sintering flue gas) of sintering centrifugal blower aerodynamic design is being carried out abroad, trying to further solve the wear problem of sintering induced draft fan from the aspect of air dynamics.

Maintenance
1. Daily inspection and maintenance
Appearance inspection: Check the appearance of the blower regularly to confirm that there is no damage, deformation or rust.
Running sound: Monitor the running sound of the blower. If there is abnormal sound, stop the machine immediately for inspection.
Vibration: Check the vibration of the blower regularly to ensure that it is within the allowed vibration range.
2.Lubrication system maintenance
Lubricating oil inspection: check the oil level and quality of lubricating oil regularly to ensure that it is within the specified range, and replace the deteriorated lubricating oil in time.
Grease replacement: For the parts that use grease, it is necessary to replace it regularly to ensure the lubrication effect.
3.Cooling system maintenance
Cooling water inspection: For the blower with water cooling, it is necessary to regularly check the flow rate and temperature of the cooling water to ensure that the cooling effect is good.
Cooler cleaning: Clean the cooler regularly to prevent its blockage affecting the heat dissipation effect.
4.Internal inspection and maintenance
Internal cleaning: Regularly clean the dust and debris inside the blower to avoid damage to the blower.
Fastener inspection: Check the fasteners inside the blower to ensure that they are tight and not loose.
5.Electrical system maintenance
Motor inspection: Check the running status of the motor regularly to ensure its normal operation.
Cable check: Check the connection and insulation of the cable to ensure that there is no damage or aging.
6.Shutdown and maintenance
Shutdown cleaning: When the blower is shut down, thoroughly clean the dust and dirt inside and outside the blower.
