Lines of Activities

CONSTRUCTION MANAGEMENT, MODERNIZATION AND RECONSTRUCTION OF BY-PRODUCT COKING INDUSTRY UNITS

Participation in development of design documentation on construction, reconstruction, expansion and modernization of by-product coking industry units, performance of designer's technical supervision carried out on a contractual basis with the customer, design institutes and design bureaus.

ENHANCEMENT OF SERVICE LIFE OF BY-PRODUCT-COKING INDUSTRY UNITS

Engineering solutions on thermal insulation and ventilation of the working zone allow carrying out repair all-year-round in any climatic conditions.

DRYING AND HEATING OF COKE OVEN BATTERIES WITH ANY GAS HEATING AGENCY

Drying and heating of coke oven batteries are separate stages of an integrated technological process. Both drying and heating follow one another and have the same pattern of gas flow.

ADJUSTMENT OF COKE OVENS HEATING REGIME

Adjustment of coking temperature range, i.e., achieving uniform temperature distribution in the heating system throughout the entire length of coke oven battery.

RESTORATION OF TECHNICAL CONDITION OF COKE OVEN BATTERIES AFTER А LONG COLD SHUTDOWN

- Technical diagnostics of coke oven battery;
- Cold repair of refractory brickwork of ovens and equipment of coke oven battery;

TECHNICAL EXPERT EXAMINATION AND CONSULTING IN COKE PRODUCTION

- Examination of design documentation;
- Technical diagnostics of coke production facilities with the issuance of an expert report;

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.
