Metering component for continuous casting of aluminum-deoxided steel

Conclusions Scale growth in the channel of the metering component during the pouring of steel deoxidized by 2.2–2.5 kg/ton of aluminum is influenced by: the amount and composition of the nonmetal impurities; the material and construction of the component; and the method of supplying the metal to the ingot mold. Stable steel pouring is secured by using a fireclay (36% Al₂O₃) metering component with widened channel (depth 55 mm), and with full protection against secondary oxidation for the metal stream.Translated from Ogneupory, No. 8, pp. 34–37, August, 1969.     

The effect of geometrical parameters of hypoid and spiroid gears on its quality characteristics

The orthogonal hypoid and spiroid gears are here considered. The point of tangency of the pitch cones is presumed to be simultaneously the calculation contact point of the teeth surfaces. Analytical relationships for the geometrical parameters and important quality characteristics depending on the contact point coordinates are given. These analytical relationships show that there is a possibility of varying the independent geometrical parameters within permissible limits. Because of this, it is shown that a pair of pitch cones with the best quality characteristics may be found.
