Periclase-Carbon Components for Use in the Refractory Lining of the Steel-Tapping Channel of a 370-Ton Converter

Tests of periclase-carbon blocks for the converter's steel-tapping channel available from the Kombinat Magnezit JSC were carried out in an oxygen-converter shop at the Magnitogorskii Metal-and-Steel Works JSC. The new refractory materials are shown to have a higher endurance as compared to the conventional periclase blocks, which made it possible to increase the operational efficiency of converters.     

Vitamin C status of inhabitants of the Gomel region

The carried out research of vitamin C status of 250 young people 17-20 years old constantly living in region of the periodic radioactive control of the Gomel region of Republic Byelorussia have shown, that in the spring the vitamin C deficiency is observed at more than 55% examined, and autumn this parameter is reduced approximately on 20%. The vitamin C provision of the women is slightly higher, than one of men. The vitaminization of the population within 1 month by polyvitaminic complexes results in twofold reduction of number examined with vitamin deficiency.     

Periclase-Carbon Refractories from the Kombinat Magnezit JSC for Use in Converter Steelmaking Technology at the Magnitogorskii Metal-and-Steel Works JSC

Cooperation between the Kombinat Magnezit Joint-Stock Co. and Magnitogorskii Metal-and-Steel Works Joint-Stock Co. in the area of exploitation of converter refractories is briefly outlined. Prospects for further improvement of the performance characteristics of refractories and converter design are discussed.     

Experience Gained in the Service of a Zonal Lining for Converters at the Magnitogorskii Iron-and-Steel Works Joint-Stock Company

A brief report on the execution of a step of a program on improving durability of the refractory converter lining at the MISW JSC in 2001 is presented. The use of refractory components PUPK-1 (available from Kombinat Magnezit) and refractory components available from Meierton Co. in various campaigns is discussed.     

Using Periclase-Carbon Converter Linings at the Magnitogorskii Iron-And-Steel Works (MISW) Joint-Stock Co.

Results of a repair-and-maintenance program aimed at increasing the durability of the converter lining in an oxygen converter shop at the MISW JSC are reported. The program includes a single-round placement of the lining, the use of high-resistance PUPK-1-grade refractory components in high-wear zones, advanced methods for lining maintenance, development of high-resistance mixtures and taphole blocks, improvement of the converter process parameters, and introduction of advanced methods for lining wear monitoring.     

Fabrication Of Periclase-Carbon Refractories With An Antioxidant And Their Testing In A Lining Of A 370-ton Converter

Periclase-carbon refractories based on electrofused periclase with an additive of passivated aluminum have been tested in service in the top cone of a 370-ton converter of the Magnitogorsk Metallurgical Works. The lining with experimental refractories withstood 1501 heats whereas the endurance of commercial periclase-carbon refractories of grades PUPK-6 and PUPK-8 equals 1185–1416 heats. It was concluded that the periclase-carbon articles with an aluminum antioxidant have good prospects for lining converters.
