Of course that will depend on what kiln you are using. This is a tested schedule used in Paragon kilns.

Casting 2" thick slab:

1) 50°/ hour to 1150° & hold for 45 minutes

2) 50°/ hour to 1200° & hold for 2 hours

3) 50°/ hour to 1250° & hold for 3 hours

4) 50°/ hour to 1350° & hold for 2 hours

5) 100°/ hour to 1450° & hold for 1 hour

6) 100°/ hour to 1550° & hold for 40 minutes

7) 9999 to 900° & hold for ten hours

8) 4°/ hour to 800° & hold for 2 minutes

9) 8°/ hour to 700° & hold for 2 minutes

10) 26°/ hour to 350° & hold for 2 minutes (in cold weather make it 200°)

How many 450mm x 450mm garden slabs do you need for garden area of 21ft x 19ft?

The answer will vary slightly depending on assumptions: will the slabs have a space between them, and will you be cutting the slabs to fill fractions. 21 feet is equal to 14.2 of the 450 mm slabs. 19 feet is equal to 12.9 of the slabs. To complete the rectangular area, 14.2 x 12.9 = 183 slabs.

What the advantage does continuous casting have over casting into ingots?

Advantages:Reduced CostImproved Quality [ Less variability in chemical composition both along the thickness and along the length and surface has fewer defects ]Increased Yield [ Since it is not necessary to crop the ends of continuously cast slabs ]Reduced Energy costs [ The slabs are sent directly to hot rolling and do not require pits for reheating and also the thickness of continuously cast slabs is half the thickness of ingot castings and thus require lower energy for hot rolling ]Less pollutionAlso the dimensions produced in continuous castings is more amenable for hot rolling. In ingot castings, the ladle is to be moved with crane for filling the molds below but here the ladle has to move short distance i.e. only over the tundish and not over each and every mould.
