By-product coking industry – is one of the most important sub-sectors of iron-and-steel industry. Coal is processed at coke plants for cokemaking, production of coke oven gas and chemical products. 

Modern coking plant – is a complex thermotechnical unit. More than 90% of the total mass of coke oven battery’s brickwork consists of refractory materials that are not destructed by many years of work at high temperatures. This includes silica, fire-clay and semiacid refractory products, as well as mortars, which serve to bind the product together in the brickwork. Coke oven battery is equipped with a variety of process equipment, piping and machinery. Structurally, coke oven battery combines from 45 to 77 coke ovens operating in set thermo-hydraulic modes. Compliance with the rules of technical operation of coke enterprises is the key to producing good quality coke and preservation of ovens brickwork. 

Technical assistance in construction, commissioning and adjustment of operating modes of new coke oven batteries, operation, modernization and renovation of the existing coke oven batteries and other by-product coking industry units – is a complex of technical services rendered by "OKOS" LLC.
