Miller and Company’s Carbon briquettes are produced from a unique combination of carbonaceous materials, rich in graphite.
It is not a coke breeze product. These briquettes can provide the following benefits, when used as a supplement to foundry coke in a cupola furnace.
A. Coke Reduction-Source of Carbon
Most common use of these briquettes is to replace/supplement the coke that provides Carbon to iron, thus reducing the amount of coke charged, resulting in cost savings. Costly supplemental additions of graphite after tapping of cupola can also be reduced.
B. Reduce Pig Iron
Because of graphite content of Carbon Briquettes, some foundries have been able to reduce the amount of Pig Iron in the charge. Cost savings are possible, depending on the relative cost of the Pig Iron vs. steel.
C. Hotter Iron
Higher iron temperature is possible by utilizing the Carbon from these briquettes to raise the tap Carbon and utilizing the coke to raise the temperature. Another alternative would be to charge more coke but at a significantly higher cost than briquettes.
D. Flexibility/Better Carbon Control
When used in combination with Silicon Carbide briquettes, this product can be used to increase/decrease tap Carbon without changing the amount of Silicon Carbide briquettes and coke.
E. Higher Melt Rate
In some cases, a higher melt rate is possible if these briquettes are used and the amount of coke is not reduced, because air blow rate will have to be increased to compensate for higher temperature.
Most foundries use this product to reduce the amount of coke charged and thus reduce their overall charge cost. Briquettes are available in 23 pound slabs on pallets for manual additions or as bulk briquettes in oval or cylindrical form for bulk handling systems. They are very strong and unlike coke will not disintegrate during handling.
4″ x 8″ x 16″ Slab
3″ x 6″ Bulk Briquettes
23 lbs. (10.4kg) each
150 pieces per pallet
or Bulk Cylinders/Ovals
Palletized, stretch wrapped on four (4) sides, banded for rail shipments or bulk shipments.
Care should be taken in determining the amount of coke replaced as certain minimum amount of coke is essential for cupola operation.
These briquettes can be used to partially replace (10-15%) coke in a Cupola. Typical replacement ratio is approximately 110-120 pounds of briquettes for 100 pounds of coke, in some cases pound for pound replacement has been achieved. Actual replacement ratio will vary, depending upon quality of coke, cupola operation as well as tap temperature and tap Carbon.
