6. Erection Procedure

6.1 Support Structure & Base Frame

• Position and fix base frames on foundation bolts.

• Level and align base frames to within specified tolerances.

• Grout and allow adequate curing time.

6.2 Support Rollers Assembly

• Place support roller shafts on bearings and adjust height and slope.

• Ensure proper axial alignment between roller centers.

6.3 Kiln Shell Erection

• Begin from the feed end and proceed section by section.

• Lift each shell section using cranes and position it over the support rollers.

• Align the shell longitudinally with the kiln centerline.

• Check ovality, runout, and slope (as per design inclination).

• Weld shell joints after proper fit-up and tack welding inspection.

6.4 Girth Gear and Pinion Assembly

• Mount the girth gear on the designated shell flange.

• Perform radial and axial runout checks.

• Align pinion with the girth gear maintaining specified backlash.

• Tighten bolts to the recommended torque values.

6.5 Drive Assembly Installation

• Install gearbox, motor, and couplings on the drive base frame.

• Check centerline alignment between motor, gearbox, and pinion.

• Ensure smooth rotation of the kiln during trial runs.

6.6 Inlet and Outlet Seals

• Mount inlet and outlet sealing systems.

• Ensure proper sealing clearance and flexibility for kiln expansion.

6.7 Refractory Lining (Post-Alignment)

• After mechanical alignment and trial rotation, proceed with refractory installation.

• Maintain expansion joints and anchoring per design.

• Dry-out and curing to be carried out as per refractory suppliers instructions.

---

7. Final Alignment and Trial Run

• Perform final alignment of rollers and shell slope.

• Rotate kiln manually and under power to confirm smooth operation.

• Check vibration, axial movement, and gear meshing noise.

• Record and submit alignment report to the client.

---

8. Safety Precautions

• All personnel must wear PPE (helmet, gloves, safety shoes, harness).

• No work under suspended loads.

• Follow KINC and site-specific safety protocols.

• Lifting tools must have valid test certificates.

---

9. Documentation

• Foundation Inspection Report

• Erection Checklist

• Alignment Report

• Trial Run Record

• Handover प्रमाणपत्र
