METHOD FOR OBTAINING BRIQUETTE TO OBTAIN TITANIUM- AND ZIRCONIUM-CONTAINING CAST IRON Russian patent published in 2014 - IPC C22B1/244 

FIELD: metallurgy.

SUBSTANCE: invention relates to metallurgical, casting production, and namely to production of cast irons operating under abrasive wear conditions. The method involves preparation of a mixture of initial material with further moulding. As initial material, crushed metal chips and metal scrap in the form of scale and scrap of ferrous metals, which are mixed with cryolite, and zircon and ilmenite concentrate, are used. Water solution (40%) of glyoxal is used as the binding agent. Components of the briquette are contained in the following ratio, wt %: metal chips and metal scraps in the form of scale and scrap of ferrous metals - 60, cryolite - 20, zircon concentrate - 7.5, ilmenite concentrate - 7.5, water solution (40%) of glyoxal - 5. The obtained mixture is homogenised by mixing, formed into a briquette by pressing and dried during 3 hours at 80°C.

EFFECT: according to the invention, use of briquettes will allow increasing wear resistance of the obtained cast iron.
