For the purpose of investigation of highly resistant refractories for use in the tuyere zones of the bottoms of converters with bottom oxygen blowing after semiproduction tests, comparative tests were made of different domestic refractories under production conditions. Tuyere refractories in the form of 280x225x190 mm blocks with a center channel under the 30 mm diameter tuyere were produced for the investigation at Magnesite Combine in TsMI-2. Blocks of the type PKhK periclase-chromite composition, type PShGP periclase with a spinel binder, type KhM chromite-periclase, KhPT, and type MKhVP periclasechromite were produced. The chemical compositions of the mixtures for production of the parts are given. Vanadium iron was blown and the bottom fuel-oxygen blowing of the vanadium iron was done using two variations. The amount of wear of the blocks and tuyeres is presented and a chemical analysis of the samples of parts after service is shown. Under the conditions of the investigation conducted, KhM chromite-periclase refractories showed the greatest resistance.
