Converters with capacity of 160 - 370 t

PJSC "Azovmash" executes the designing, manufacture and completed delivery of the equipment for the converter shops with converters from 160 to 370 t.  The experience accumulated for many year in designing and manufacture of converters for service under diverse technical and climatic  conditions has allowed to develop optimal designs ensuring high reliability and long service life, repairability and convenient maintenance and making  steels according to the newest technologies.   

 

Depending on the adopted processes of steel making, the converters are furnished with the systems of the top blowing of melted pig with pure industrial oxygen, with a supply system of energy carriers through the bottom or with a  system for combined blowing by the process gases. The converters are equipped with mounted multimotor tilting drives.

The converters  of Azovmash  design feature  an important property – possibility of replacement  of small  and medium  capacity  converters  with  vessels of large capacities with their accommodation within the existing spaces and without changing  the foundations  and metal  structures of the plant. This procedure for replacing the converters was successfully used at the Ukraine metallurgical enterprises in Mariupol, Krivoi rog, Enakievo, as well as at the Novolipetsk, Nizhniy Tagil, Weast- Siberian and Chelyabinsk integrated iron-and steel works in Russia, in Raahe (Finland) and others.


The service experience of the equipment at the metallurgical works has allowed to create on the base of the large number of the inventions and “know – how” the original designing solutions of all units that enshures the high technical-and-economic indexes.
