In Kuznets Metal lurgical Combine, two types of containers have been tested for centra l ized transportation of ferroalloys from the main warehouse to the using shops~ scoop type and grab bucket type. The scoop type had a number of shortcomings and therefore their use has been abandoned. At the present t ime grab bucket type containers with a volume of 3 m 3 holding 12-13 tons of ferroalloys are used. Their dimensions are 2030 mm long, 1600 mm

wide, and 1600 mm high to the upper edge. The case of the container has four lugs, two for traasporting and two for unloading.

Previously, ferroalloys from the gondolas were unloaded through a hatch onto a platform placed at the 1eve! of the rails and then manual ly loaded into containers. Later this operation was mechanized. Along the railroad tracks a trench was dug and lined with meta l plates. On the bottom of the trench along the whole length of the car containers are placed direct ly against each other and the side wall, and when the hatches are opened the ferroat!oys drop direct ly into the containers.

The loaded containers are placed to the side by a 40 ton railroad crane or loaded on railroad cars for del ivery to the using shops. Empty containers are placed at a release point.

In the combine at the present t ime al l ferroalloys, with the except ion of small lots which are snppIied in drums or boxes as specified by standards, are delivered to the using shop in containers. In the combine containers are used not only for transporting ferroalloys from the warehouse to the shop, but also for temporary storage Of these materials. W ith more than 500 containers 400-500 tons of ferroalloys may be stored in containers ready to be unloaded. This makes it possible to significantly decrease the amount of warehouse work.

In addition, in using the container storage system the working conditions of the warehouse workers are i m - proved. When loading the containers the number, type and chemica l analysis of the load is recorded in the proper book. Therefore, at any moment i t is possible to find the required container and in the minimum of t ime deliver

i t to the specified point.

In the mel t shops the containers with the ferroalloys are unloaded into mechanized receiving Bunkers with

capaci t ies of 60-100 tons each and then del ivered in charging boxes or special bunkers to the point of use. Ferro- chrome from the containers is unloaded direct ly into charging boxes.

The use of containers for transporting ferroalloys, powders, l ime, and other toose ma teda i s has freed a Ngni ~ ficant number of loaders for other work and reduced the cost of moving a ton of mate r ia l from 16;4 kopecks (19453 to 4. 02 kopecks (1969). In addition, the manual labor used ear l ier for loading railroad cars at the warehouse and un~

loading them at the using shops has been comple te ly e l iminated.
