The efficiency of calcium introduction in steel is determined from tests in which 08, and steel is treated with silicocalcium powder wire in a 320-t steel-casting ladle, so as to ensure the best performance of a continuous bar-casting machine. The assimilation of calcium mainly depends on the oxidation of the slag: other conditions being equal, calcium assimilation is most complete and stable with <2.0% (FeO) in the slag and >0.015% Al in the metal. In these conditions, the consumption of the silicocalcium powder wire is unchanged. © 2010 Allerton Press, Inc. Source

Experience in the hot repair of coke furnaces by ceramic surfacing over 12 years at OAO ZSMK is reviewed. It is established that the calculation method for ceramic repair blends adopted at Chernogolovke must be employed. At OAO ZSMK, ceramic blends are produced from the initial components on special equipment. The ceramic patches obtained from these mixtures last 4-4.5 years. Since 2004, original equipment covered by Russian patents has been used for hot repair by ceramic surfacing. © 2010 Allerton Press, Inc. Source

Forged steel 50 rollers are used in the roughing group of wire and small-rod mills. In intense rolling, the roller pin often breaks, since the pin experiences the maximum stress. It is established that the fracture is of fatigue type, and three disintegration zones are identified. Crack propagation is due to the stress in the crack tip. The rate of crack propagation in cyclic loading depends on the structure of the metal, the grain size, and the mechanical properties of the rollers. The unbroken rollers are characterized by high values of the impact strength, initial and final temperatures of ingot forging, and σy/σB. An empirical dependence of the number of roller rotations to pin fracture on the mechanical properties of the material and the loads is established. Small-grain structure of the metal matrix and purity of the metal ensure a good combination of strength and plasticity. © 2010 Allerton Press, Inc. Source
