Since providing the right coke for the job is absolutely critical to our customers' success, quality control is top priority at Walter Coke. Extensive sampling and testing is conducted at all critical stages of production and the most technologically advanced equipment and procedures are utilized throughout the process.  Additionally, Walter Coke’s commitment to excellence is demonstrated by its ISO 9001 certification for furnace and foundry coke, as well as numerous fiber products.

After pushing the coke out of the ovens, the hot coke is quenched with the proper amount of water, then air-dried in preparation for sizing. The coke is sampled at several points prior to loading.

Furnace and foundry coke are sized at separate screening stations. A crusher helps control top sizing of furnace coke prior to screening.  Samples are taken throughout the loading process. Results from sampling are stored on computer and readouts are generated as required. Every car of coke must meet customer specifications prior to shipment.
