The effect of the design of the metal receiver slab continuous casting machine on the movement of metal in the intermediate ladle when the metal stream deviates from the desired position. Part I. Formulation of the problem

The article is devoted to assessing the effect of the design of the metal receiver in the intermediate ladle of the large capacity slab continuous casting machine on reducing the turbulence of flows when the metal stream deviates from the required position during casting. The results of computer simulation of industrial variants of displacement of a stream of metal from a steel pouring ladle to an intermediate ladle from the target input point are presented. The distribution of metal flows in the tundish is compared with different designs of metal receivers. Recommendations are given for reducing flow turbulence for the cases considered. Ill. 6. Ref. 5.

Mathematical Analysis and Mechanical Modeling of an Inoculation System on Feeder Control for Pouring Unit in a Foundry Station

This paper presents on feeder control; the inoculation device has been designed to automatically add inoculating powder to metal stream working with an automatic pouring unit. This system applies a constant dosage of inoculant easily modified by the control unit, with precise repeatability of the process. It incorporates a system of the instant direction of faults at all times, to ensure proper operation. In this project, the human effort is reduced by automating the inoculant feeding mechanism performed in a foundry. By doing pouring in manual manner, it ends up in reducing the rejection of production 2% owing to poor inoculation which disturbs the company's production. This system is used to feed the inoculant to the molten metal in a highly precise amount as per the requirements. After researching various feeding mechanisms, concluded with feeding machine with the help of screw which is more adoptable for desirable number of inoculants to be transferred. The mathematical analysis has been done and it is proven that satisfies the design criterions for modeling of the proposed system. The mechanical modeling is designed in such a way that inoculant occupies in two class of separate hoppers.

Casting of Aluminum Alloy Rod by a Single Wheel with V-Groove

Casting of a convex rod from 5182 aluminum alloy was attempted using a single wheel caster with a V-shape groove. The diameter of the mild steel wheel was 600 mm, the angle of the vortex was 90 degrees, and the width of the groove was 20 mm. Important factors to cast a rod with a convex shape are the speed of the molten metal ejected from a hole-nozzle and the collapse angle between the molten metal stream and the wheel. Important factors that affected the cross sectional shape of cast-bar were the speed of molten metal ejected from the hole-nozzle and the collapse angle of the molten metal against the wheel. A collapse angle close to 90° was better than an angle less than 90°. Casting speeds of 5 m/min and 15 m/min were employed, which resulted in convex cross sectional rod areas of 30 mm2 to 190 mm2.
