Foundry production is one of the most labor-intensive in heavy engineering. Scientists do a lot to ensure that the work of foundry workers meets the requirements of progress.

New mechanisms of the foundry industry.
Alternating frames with large cast parts of various configurations.
A crane carries a cast part around the workshop.
For the individual production of castings, a system of molding lines based on forty-ton, twenty-seven and six-ton shaking tables was created and implemented at Uralmash.
The line provides for, during a quick change of equipment, shaking with pressing, removing excess mixture, tilting flasks, and removing models.
High-speed drying of half-molds is carried out here by creating a vacuum under the flask.
Hot gases penetrate the mold faster and speed up the drying process.
Making a mold for casting.
The Kramatorsk Institute of Mechanical Engineering has developed an original molding method - pulse.
A cartoon explaining the essence of the pulse molding method.
Pulse molding unit.
Pulse units are built into molding lines.
One of such installations operates at the Bezhitsa Steelworks.
Pouring metal into a mold.
Universally prefabricated core boxes developed by the Kramatorsk Institute.
Up to 60 boxes, which are stronger than wooden ones, can be assembled from one set of prefabricated elements.
Multiple use of universally prefabricated core boxes saves on timber.
Filling the boxes with molding mixture.
Extracting the casting.
Method of centrifugal production of shell cores.
At the Bezhitsa Steelworks, this method is used to produce cores for casting wagon axle boxes.

Cleaning heavy castings from molding and core mixtures.
An electrohydraulic casting cleaning unit developed at Uralmash.
A container with castings and electrodes is lowered into water.
Unit control panel.
Powerful electric discharges create hydraulic shocks underwater.
Within a few minutes, all castings are cleaned of mixtures.
Preparation of quartz mixture molds.
Spent molding mixtures.
An unit for dry regeneration of liquid glass-based mixtures installed at Uralmash.
Developed by the Central Research Institute of Heavy Engineering.
A cartoon explaining the operation of such an unit.
The Kremenchug Technological Institute of Carriage Building proposed a method for dry regeneration of spent sand-clay molding mixture.
When the rotor rotates, the grains of the molding mixture are thrown by centrifugal force onto the annular slope and, as a result of multiple collisions, are freed from clay.
The dust is carried away into the ventilation systems.
Removal of risers from heavy steel castings.
Mechanized remote-controlled units for cutting off large risers with a diameter of up to two meters.
Automatic robotic machine for the production of high-precision castings with a clean surface from aluminum alloys.
Castings made on such machines do not require mechanical processing.
Production of parts from metal powders.
A part pressed from metal powder, after heat treatment, acquires physical and chemical properties close to the properties of the metal.
Automated line for centrifugal casting of car axle box bodies on a sixteen-position carousel device.
Each positional nest of the carousel has an independent centrifugal machine.
The high rotation speed of the chill mold up to 600 rpm ensures the production of a vertical cylindrical hole.
At the last position, the chill mold together with the hardened casting is replaced with a new, empty one.
