Metallurgical coke

All metallurgical coke is produced using the "byproduct" method. Destructive distillation ("coking") of coal occurs in coke ovens without contact with air. Most U. S. coke plants use the Kopper-Becker byproduct oven. These ovens must remain airtight under the cyclic stress of expansion and contraction. Each oven has 3 main parts: coking chambers, heating chambers, and regenerative chambers. All of the chambers are lined with refractory (silica) brick. The coking chamber has ports in the top for charging of the coal.

metallurgical coke is the quintessential fuel for melting iron in ovens, ensuring the iron achieves exceptional heat. It is expertly designed to uphold outstanding air permeability by supporting stock columns. As such, our foundry coke embodies essential qualities: large block size, minimal activity, fine porosity, robust anti-crush strength, and impressively low levels of ash and sulfur. Beyond the standard 10% ash foundry coke, our special grade variant shines with an ash content of just 8%. This remarkable casting coke offers unique benefits, featuring ultra-low ash and sulfur levels coupled with reduced apparent porosity. Predominantly aimed at the export market, this superior casting coke is ideal for precision casting applications, meeting the highest standards.
