Step 2.2:

Check the radial runout of the tyre in the actual installation. Measurement should be taken in 3 and 9 o'clock position at the same time. Please use Polysius measuring Protocol Annex B. Record your readings for reference.

Step 2.3:

Marking on kiln shell for cutting. Mark reference lines next to the kiln section that has to be removed. The reference lines have to be marked on the remaining part of the kiln, not on the scrap tyre section! These reference lines have to be made by means of a scriber. Use visible and permanent marking ink.

Step 2.4:

Four backing plates (machined, rectangular, 25 mm thickness) have to be welded to the kiln shell. These backing plates are working as stoppers and must be positioned precisely for the final position of the tyre. Fig. 13

Step 2.5:

Full welding of two ( 2 ) spider supports inside the existing shell approx (1) ONE meter back from the replacement section joints. Angle sections 75mm x 75mm x 10mm welded to a 400mm Ø center disc. This is to maintain cylindrical dimensions throughout the repair works. Fig.4

Phase 3: Mounting / Rigging up & Alignment of the new Kiln shell section (Including trye) Step 3.1:

Four backing plates (machined, rectangular, 25 mm thickness) have to be welded to the kiln shell. These backing plates are working as stoppers and must be positioned precisely for the final position of the tyre. ( Reference: Polysius _ Montage Laufring grob e ). Refer to installation of tyre, Fig 14.

Step 3.2: The tyre has to be shifted against these stoppers, centered in radial direction and then another 4 backing plates (Fig.14) have to be positioned against the tyre and then welded to the kiln shell. Step 3.3: After that the tyre fixation as to be installed step by step in 12o'clock position and tack welded. After the installation of all fixations, the welding of the fixations can be started. The axial fixation for the tyre must not be welded at this point of the pre-assembly

NOTE:


Step 3.4: Arrest the new kiln shell assembly with web / wire rope slings & shackles – securely hooked on the mobile crane, ready for lifting. Step 3.5: Slowly swing the boom westward & position new kiln shell on the space for replacement. Fig.16.

Fig. 16 Step 2.3: Slowly & precisely, lower down the new kiln shell assembly to rest & aligned on the existing kiln shell. The boom should be steady. Step 3.3: Install & full weld a series of brackets for draw bolts inside the old kiln shell. They should be welded uniformly around the inside part of the old kiln shell at both ends and are spaced approx. 400mm apart. Two (2) main versions of draw bolt brackets are used. POLYSIUS recommend an angle cleat design (while F.L.S. choose a “U” section format). Pre-assembly / Installation tolerances – refer to Annex A

Fig.17 Step 3.4: On alignment, there may be some trimming required for a good fit up. When positioned, the joint for welding should be a 60° included angle – single “V” preparation with a 2mm root face bull nose to both parts.

Step 3.5: Check alignment and completely weld along one side (existing kiln shell), a series of approx. 15 strong backs across the two joints. Fig. 18.

Fig.18 Step 3.6:

Weld the draw bolt brackets to the new kiln shell section. Insert 30mm fully threaded draw bolts across the joint & attach four ( 4 ) hexagonal nuts per bolt, ( 2pcs outside & 2 pcs inside ) – this is to create a push & pull mechanism.

Step 3.7:

Weld the draw bolt brackets to the new kiln shell section. Insert 30mm fully threaded draw bolts across the joint & attach four ( 4 ) hexagonal nuts per bolt, ( 2 pcs outside & 2 pcs inside ) – this is to create a push & pull mechanism. Fig. 19.

Fig. 19 Step 3.8:

Weld in place a series of approx. 30 equally spaced screw blocks to the new kiln shell section so that they cross the joint. These will be used to adjust & align both cylinders Fig. 20.

Fig. 20 Step 3.9:

Manually rotate the kiln in order to conduct a true alignment check. As the kiln rotates, 12 datum points are selected & measured using a polar diagram, one (1) meter away from the each joint. This determines the true center line of the kiln.

If the test proves unsatisfactory, the strong backs are released by gouging and the draw bolts are adjusted where necessary. Strong backs then re-welded and a further alignment check is conducted until the kiln measures a true alignment. Fig. 21.

Fig. 21 Differences in the diameters have to be uniformly distributed on the circumference to avoid edge misalignment. Max. differences in the edge misalignment are 1 mm. (Polysius data)

Remarks by:

Executioner Step 3.11:

Prior to welding, PRE-HEAT IS CRITICAL. The correct pre-heat temperature has been calculated on Annex B. (Method case study for the welding of Kiln sections provided for Rugby Cement Crown House by Mike Bedford) Pre-heat of 120°C to a distance of 150mm from each side of the joint. A thermal crayon (preferably a pyrometer) Fig. 22, should be used to monitor the temperature and ensure that this temperature of 120°c is maintained throughout the welding process. Re-heat as necessary.

Fig. 22 NOTE:

The welding electrodes should be heated for two (2) hours in a suitable baking oven.

Step 3.12:

Commence welding from the outside of the kiln, Fig. 24 employing two (2) welders on each joint working continuously around the clock. Deposit fully a single root pass weld using a 3.2mm Ø electrodes. De-slag thoroughly using an air chisel.

*** During the complete repair, the kiln should be rotated manually as necessary to assist convenient weld positioning ( >4.2m kiln = 8 spokes; 4.8m kiln =m 10 spokes ). Step 3.13:

The hot pass, intermediate welding can be completed in stages to fill 2/3 of the weld preparation. DO NOT CAP. To obtain optimum mechanical soundness – weaving must be avoided, therefore, use stringer beads up to a deposit width of twice the electrode diameter.

Step 3.14:

Return, to the inside of the kiln and by gouging, remove the brackets, screw blocks & spider supports. Grind to smooth finish gouged areas. Fig. 24.

Fig 24 Using 8mmØ carbon electrodes & the air arc gouging process, conduct an internal root preparation by back gouging into the external root weld to a depth of approx. 10-15mm. This will also remove any possible slag inclusions. Grind properly the “U” to remove all gouging residues. Step 3.15:

Ensure that the pre-heat is maintained & deposit an internal root weld, Fig.25 using 3.2mmØ electrodes. Complete hot pass & cap with 4.0mmØ electrodes. Grind internal surface flush, as welds left proud & undercut can have the effect of multiplying the stress.

Fig. 25 Step 3.16:

Return to outside of the kiln shell & continue / complete filling and capping weld deposits, ensuring stringer bead format, using 4.0mmØ or 5.0mmØ electrodes.

Step 3.17:

Wire brush thoroughly the inside & outside welded joints of the kiln shell. Visually inspect the finished welded joints. Suspected areas should be investigated by using dye penetrant (preferably – ultrasonic testing).

Step 3.18:

Weld is subject to a 100% radiograph upon completion. Gouge & re-weld any defects.

Step 3.19:

Reinstallation of kiln shell cooling fans, ducting and other kiln accessories in place. Full welding of ducts & supports.

NOTE:


.

Phase 4: Safekeeping Step 4.1:

Removal of all temporary welded supports & pad eyes, grinding to smoothen area.

Step 3.2:

Removal of all scaffolding pipes (by the Scaffolding Contractor)

Step 3.3:

Disconnect the welding cables ( ground cable ) from the kiln area. Housekeeping of all oxygen & acetylene cylinders. Empty cylinders should be returned back to the warehouse.

Step 3.4:

General cleaning of work area and removal of backfilled materials to FRCC designated area. Using the Payloader, load all these scrap & haul to the scrap yard for proper disposal.

Step 3.5: Travel the mobile crane outside the kiln area.
