What are cupola furnaces for?

Cupola furnace, in steelmaking, a vertical cylindrical furnace used for melting iron either for casting or for charging in other furnaces.

How does a cupola furnace work?

To begin a production run, called a 'cupola campaign', the furnace is filled with layers of coke and ignited with torches. Some smaller cupolas may be ignited with wood to start the coke burning. When the coke is ignited, air is introduced to the coke bed through ports in the sides called tuyeres.

What is the difference between cupola furnace and blast furnace?

Abstract: Blast furnace and cupola furnace are furnace aggregates used for pig iron and cast iron production. ... They are compared by the contribution of the blast furnace slag cooled in water and on air, and cupola furnace slag cooled on air and granulated in water.

What metal is produced by the cupola furnace?

How do you attach a cupola to a metal roof?

METAL CUPOLA INSTALLATION GUIDE:

2. Mark the Cupola Base & Cutout - Remove the screws holding the 2 opposite (metal) side panels of your cupola base, keep these pieces to reattach to original position.

Where should a weathervane be placed in a house?

Ideally you want a weathervane to look part of the overall architecture of your home. Small weathervanes may be suitable for sheds and annex style buildings but they may look out of place on top of a large house. Similarly if the weathervane is too big for a home it can look garish or unsuitable.

How do you balance a weathervane?

Any good vane should balance if positioned horizontally on its side while resting in its spindle. By their nature, vanes must have the most exposed surface area on the downwind side. This usually means that it must be counterbalanced by adding weight to the upwind side. Lead is most often used.

How do you install functional cupola?

Cupolas come in three sections - base, vents, and roof - to make assembly easier. Place the vents (midsection) on top of the base and attach with 2” screws, using the pre-drilled holes. Then place the roof on the midsection and fasten with screws, again using the pre-drilled holes.
