Foundry Coke

Foundry Coke is the special coke that is used in the furnaces for the production of ductile and cast iron products. It helps in maintaining the required carbon content of the metal and acts as a source of heat. The production of foundry coke requires lower temperature conditions and longer time duration then the blast furnace coke.

Topaz Impex Incorporated (TII) manufactures Hi-quality Foundry Coke as per the Customer’s requirement. TII is well aware of the effect of coke properties on cupola furnace operation which is described below:

Metallurgical Coke

Met-Coke is general :

term for the coke used for metallurgical purposes VIZ Iron Foundries, Steel Foundries, Non-Ferrous metal castings, Lead & Zinc smelters, secondary Steel Producers, Chemical Plants VIZ Soda Ash & Calcium Carbides Plants, Ferro-Alloy Plants & Pig Iron Producers using Blast Furnaces.

LAM Coke is known as Low Ash Metallurgical Coke.

During the manufacture of Met-Coke using Coke Oven Furnaces, the hot coke produced is taken to a Quenching Tower for quality / cooling the coke to normal temperature. By virtue of the coals available in the nature & the characteristics of the coking process, the quenched coke will not have one uniform size but mixture of various sizes. These are sorted out into fractions using coke cutters 7 screens & graded into following fractions which are basically defined as follows-:

1. Balst Furnace Met-Coke....... Sizes from +20 or +25 or +30mm up to -60 or 80 or 90 or 100mm
2.Foundry Met-Coke.......Sizes of +60mm or +80mm or +90mm or +100mm.
3. Nut Coke.......Sizes barely from +20mm to -30mm or -40mm.
4. Pearl Coke.......Sizes from +10mm to -20mm or -25mm
5.Coke Breeze.......Sizes less than -10mm.

As such, the coking process used is the Same for all the types of coke as above.
