The sealing of Aluminum Alloy Quenching Furnace is crucial to ensure the stability of the furnace atmosphere, the preservation of heat, and the improvement of heat treatment effect. The following are several key measures on how to ensure the sealing of Aluminum Alloy Quenching Furnace:
Furnace door and furnace body sealing design:
Aluminum silicate refractory fiber material is used as the sealing material between the furnace door and the furnace body of Aluminum Alloy Quenching Furnace. This material has good high temperature resistance, corrosion resistance and sealing performance.
After the furnace door is closed, it fits tightly with the insert knife of the furnace mouth to ensure that there is no heat dissipation and prevent the external cold air from entering to affect the atmosphere and temperature in the furnace.
Furnace door opening and closing mechanism:
The furnace door opening and closing mechanism of Aluminum Alloy Quenching Furnace is reasonably designed, and adopts mechanical automatic or electric automatic type to ensure that the furnace door can be accurately and smoothly sealed when closed.
Set the travel switches such as switch in place and deceleration in the travel direction on both sides of the furnace door to control the opening speed and closing force of the furnace door to avoid poor sealing due to improper operation.
Furnace door sealing technology:
For vertical aluminum alloy quenching furnace, when the furnace door is closed, the upper furnace door first contacts and squeezes each other, causing the furnace door to be vertically squeezed along the inclined guide rail on the lower bracket and the guard plate around the furnace door to complete the sealing.
The double-layer frame structure is reasonably designed to avoid scratching between the sealing rope and the furnace mouth guard plate, ensuring that the furnace door and the furnace body fit tightly.
Selection and maintenance of sealing materials:
Select aluminum silicate refractory fiber materials with high temperature resistance, corrosion resistance and good sealing performance as sealing materials.
Check the status of the sealing material regularly, and replace it in time if it is damaged or aged to ensure the sealing effect.
Sealing test:
During the equipment commissioning stage, a sealing test is carried out to ensure that there is no air leakage when the furnace door is closed.
During use, regular sealing checks are carried out to ensure that the sealing performance of the equipment is always in good condition.
In summary, through reasonable design of furnace door and furnace body sealing, furnace door opening and closing mechanism, furnace door sealing technology, selection and maintenance of sealing materials, and sealing testing, it can be ensured that the Aluminum Alloy Quenching Furnace has good sealing and provide a stable environment for the heat treatment of aluminum alloy materials.
