DINKONDA GLOBAL Power Plants Special Cardan Type Blast Furnace Air Supply Device Universal Hinge Type Corrugated Compensator Metal Expansion Joint

DINKONDA GLOBAL Power Plants Special Cardan Type Blast Furnace Air Supply Device Universal Hinge Type Corrugated Compensator Metal Expansion Joint

Product Overview

The Cardin type blast furnace air supply device is a core specialized equipment for blast furnace hot air system, specially designed for blast furnaces with a volume of 600m ³ and above. It is installed between the hot air duct and the blast furnace tuyere for high-temperature hot air transportation. The product adopts a Cardan universal joint compensation structure, relying on a compound universal joint type corrugated compensator to achieve multi-directional angular displacement compensation, which can eliminate the additional load caused by thermal expansion and safely and stably deliver high-temperature hot air into the blast furnace. It is a key equipment for the air supply pipeline of large and medium-sized blast furnaces.

Structural Composition

1. * * Horn tube * *: a transitional guide pipe between the hot air duct and the compensator, optimizing the flow field, reducing high-temperature hot air resistance, and withstanding alternating high-temperature heat loads.

2. * * Compound universal joint compensator * *: It consists of two sets of universal joint corrugated compensators and a middle connecting pipe combination, which is the core compensation component of this device. It relies on the combination of two sets of corrugated pipe angular displacement to achieve omnidirectional displacement compensation; The internal spherical structure has small expansion joints, and the gap size remains stable during displacement.

3. * * Bent pipe * *: a turning component of the pipeline, connecting the compensator and the straight blowing pipe to change the direction of hot air delivery.

4. * * Peek hole * *: Inspection observation window, which allows for intuitive viewing of the internal combustion conditions of the air outlet without stopping the machine, facilitating on-site operation and monitoring.

5. * * Direct blow pipe * *: The hot air terminal conveying pipe section guides high-temperature hot air into the blast furnace tuyere.

6. * * Upper tensioning device * *: The upper limit tensioning component constrains the maximum deflection angle of the compensator, protects the corrugated pipe, and prevents over angle deformation and damage.

7. * * Lower compression device * *: The lower support compression component carries the weight of the entire air supply device, suppresses operational vibration, and stabilizes the installation position of the equipment.

Product Features

1. * * No blind plate force output, no additional load generated**
The core advantage of the compound universal joint structure is * * no blind plate force output * *, which does not transmit additional thrust to the hot air duct and small sleeve during equipment operation, protecting the hot air duct and furnace components from the root and greatly reducing the risk of pipeline stress damage.

2. * * Angular displacement compensation capability in all directions**
Two sets of universal joint corrugated compensators work together to absorb multi-directional thermal deformation displacement through angular displacement combination, adapting to the spatial deformation caused by complex thermal expansion and foundation settlement of the blast furnace body and hot air shroud after heating up.

3. * * Spherical sealing structure, stable expansion joint**
The internal spherical structure is designed with small gaps between expansion joints, and the size of the gaps will not change with displacement deformation, ensuring high-temperature hot air sealing performance and reducing hot air leakage.

4. * * Controllable deflection angle, stable air supply**
During the product design phase, the deflection angle of the compensator can be accurately limited according to the working conditions of the blast furnace. While meeting the displacement compensation requirements, it ensures the stability of the hot air channel shape and guarantees uniform and efficient air supply.

5. * * High temperature and high pressure resistance, suitable for harsh working conditions of blast furnaces**
It can withstand high temperature hot air from 1100 ℃ to 1380 ℃ for a long time, with a design pressure coverage of 0.3MPa to 0.65MPa. It is resistant to high temperature fatigue and hot air erosion, meeting the continuous and long-term operation needs of large and medium-sized blast furnaces.

6. * * Convenient operation and maintenance, safe and reliable**
Integrated peephole design for easy daily inspection; The up and down tightening device provides limit protection for the corrugated pipe, ensuring safe and stable operation of the equipment and reducing maintenance frequency.
