Purpose of the development: New resource-and energy-saving technology and device designed to improve the stability of converter lining using cheap gunning masses in the steel industry.

Recommended application field: Metallurgy.

Advantages over analogues: No analogues.

The development stage readiness: Ready for application

Technical and economic effect: Implementation: The technology has wide industrial test and is used in the normal process of steelmaking at PJSC "ArcelorMittal Krivoy Rog". Results of Study: Technology hot relining 160-ton converters by applying slag skull using gaspowder inflating final slag cheap gunning mass based on unroasted dolomite using a special rotating gunning lance introduced in CCC JSC "Mittal Steel Krivoy Rog".

Description of the development:
()
Developed and implemented a new resource and energy-saving technology and design scull lance providing increased resistance lining 160 - ton converters BOF shops of " Mittal Steel Krivoy Rog " by applying slag skull using gaspowder inflating final slag cheap gunning mass based on unroasted dolomite. Patenting , competitive results : Obtained in 2010 Ukraine declarative patents of utility model number 50940 " Gunite - lance relining converter " and number 50942 "Method relining converter " (authors - Chernyatevich AG , etc.). Owned by DSTU , introduced in constant commercial operation in BOF shop JSC " Mittal Steel Krivoy Rog " . The economic attractiveness of development for market promotion , application and realization, parameters, price : the economic effect of $ 5477379 USD. ( 1.19 USD / t.stali ) due to cheaper gunning mass flow and save it to 0.87 kg / t steel.
