What are the installation methods for industrial annealing furnace manufacturers?

The installation methods for industrial annealing furnaces vary depending on furnace type, structure, and specific requirements, but generally follow these fundamental steps and principles:

I. Preliminary Preparation

Design Review: Verify the annealing furnace's design drawings, technical specifications, and installation requirements to ensure compliance with production needs and safety standards.

Foundation Construction: Execute the annealing furnace foundation works according to design drawings, encompassing excavation, reinforcement tying, formwork installation, and concrete pouring. Ensure the foundation is robust, level, and dimensionally accurate.

Equipment Acceptance: Conduct acceptance inspection of the annealing furnace equipment, verifying specifications, model, quantity, and quality against requirements. Prepare necessary installation tools and materials.

II. Installation Procedures

1. Process Steel Structure Installation

Bottom Process Steel Structure Installation: The industrial annealing furnace manufacturer first installs the bottom process steel structure, ensuring its horizontal and vertical alignment meets design specifications.

Layered Installation: Employ a segmented, layer-by-layer installation technique, progressively erecting the process steel structure upwards to the furnace shell top. After each layer is installed, perform alignment welding to ensure structural stability.

2. Furnace Shell Installation

Bottom Plate Installation: Following completion of the bottom process steel structure, install the furnace shell bottom plate and secure it in alignment.

Installation of Furnace Shell Side Plates: Utilise the platform's auxiliary centreline to position the furnace shell side plates. Lift and position them sequentially, performing preliminary alignment and securing. Install the furnace shell side plates layer by layer upwards until reaching the top of the furnace shell.

Overall Alignment of Furnace Shell: After complete installation of the furnace shell and process steel structure, precisely align the verticality of the furnace shell plates and the squareness of the furnace shell's upper and lower openings from top to bottom. Ensure the furnace shell installation accuracy meets requirements.

3. Installation of Other Components

Guide Sleeve Installation: The industrial annealing furnace manufacturer installs guide sleeves to ensure smooth lifting and lowering of the outer casing during hoisting operations.

Exhaust Hood and Exhaust Pipe Installation: Install the exhaust hood and exhaust pipe, taking thermal expansion factors into account to ensure unimpeded exhaust flow without affecting other components.

Burner and Heat Exchanger Installation: Install the burners and heat exchangers to ensure uniform mixing of gas and air, achieving optimal combustion efficiency.

4. Pipework Configuration

Pipe Internal Surface Preparation: Clean the internal surfaces of pipes, removing surface rust and contaminants.

Pipe Welding: Employ suitable welding techniques (e.g., TIG welding) for pipe joints, ensuring weld quality meets specifications.

III. Post-Installation Commissioning and Acceptance

Individual Component Testing: Conduct standalone testing of all annealing furnace components to verify proper operation.

No-Load Interlock Testing: Perform no-load interlock testing to inspect coordination between components.

Furnace Drying: Execute furnace drying to eliminate moisture and impurities from the chamber.

Acceptance: Conduct acceptance inspections according to relevant standards and specifications to confirm installation quality compliance.

IV. Safety Precautions

Safety Regulations: Strictly adhere to safety operating procedures and installation specifications to ensure a secure and orderly installation process.

Protective Measures: Implement necessary protective measures during installation, such as wearing protective equipment and setting up safety warning signs.

Quality Inspection: Conduct quality inspections and controls at critical stages of the installation process to ensure compliance with requirements.

In summary, the installation method for industrial annealing furnaces is a complex and meticulous process requiring strict adherence to design requirements and installation specifications.
