Through a combination of more than 90 years of operating experience, an uncompromising commitment to our customers, and substantial capital investment, Walter Coke has taken the science of making premium-quality blast furnace and foundry coke to the highest level.

Continuous efforts to improve the quality of our products, as well as comply with our customers' most exacting requirements, include state-of-the-art equipment and technology such as:

• Rotary car dumper for unloading selected coals into the preparation system
• Air blaster unloading controls that ensure a steady flow of coal for uniform preparation
• Coal pulverizers to ensure proper sizing of coals for optimum blending and coke production
• Fourteen blending silos to separate and contain the sized coals prior to blending
• The establishment of standards for precise blending of coals as established by petrographic analysis of individual coals
• Bulk density control to ensure that the physical characteristics of the coke delivered to our customers is consistent from one car to another
• Industry-leading quality control methodologies are used for sampling and testing. This ensures that the proper coals are used in the correct proportions to achieve the required coal blend. The data is then processed such that all information can be recalled and the blend duplicated at any time.
• Walter Coke requires all coal suppliers to furnish specifications on their products. The coals are then evaluated against the chemical and physical parameters (including petrographic data) necessary to ensure compliance with customer standards.
