Best technology
In our production facilities, we apply the most advanced technologies, which have proven themselves in
Russia and abroad and consistently guarantee the maximum quality of products.
High casting quality at RM Rail VKM-Steel is ensured by the HWS-Sinto automatic vacuum-film forming
line.
The technology is based on using dry sand without the addition of any binders, which reduces the amount of mixture waste and lowers the cost of castings. In addition, the surface of the products is less rough (≈100 μm), "hot cracks" are excluded. The line is fully automated and its maximum capacity is 10 molds per hour.
Thanks to the LAEMPE sand core shooting machines, we can produce cores using the Cold-Box-Amine process in complex configurations (up to 120 kg). They have the necessary strength, minimal crumbling and excellent surface quality. The formation of gas and sand defects in castings is excluded.
Specialized industrial pass-through furnace with gas heating of ThermoGaz LO series is designed for
continuous technological processes of normalization and annealing of railway castings.
Three modern electric arc furnaces ensure high productivity of the melting site.
An alternating current steelmaking furnace with a capacity of 16 t manufactured by Thermomelt (Italy).
It is equipped with a system of automatic dosing of ferroalloys supply, which eliminates manual labor of steelworkers and allows to increase the accuracy of the chemical composition of liquid steel by alloying elements. The water-cooled vault of the furnace requires minimal repairs and helps to reduce refractory material consumption. Due to the increased transformer power and the oxygen and coal mixture injection system, the melting time gets 30–40% shorter.
The next-generation shot blast chamber from Stem (Slovenia)
significantly improves the casting cleaning quality.
At RM Rail Ruzkhimmash, TRUMPF 3040 laser cutting machines are used for metal cutting and nesting, including for thin sheet and non-ferrous metal processing.
These machines are capable of processing sheets of up to 4,000x2,000 mm with the maximum metal thickness of up to 18 mm.
In 2023, the company expanded its laser cutting machine fleet.
Han's Laser fiber optic laser machines
With a power of 20 kW, they can cut parts from mild steel of up to 50 mm thick and stainless steel and aluminum alloys of up to 60 mm thick. The cut precision and the resulting roughness allow to reduce or completely eliminate machining of parts and, therefore, reduce the production costs without compromising the product quality.
KOIKE gantry CNC plasma cutting machines
Used for machining and cutting sheet metal, including non-ferrous and high carbon (stainless) steel. The advantages include perfect cut quality at the ends and a perfect match to the required parameters.
Pilot process complex
for shaped cutting of rolled products made of low- and high-carbon steels and their alloys. The state-of- the-art machine is equipped with 10 cutting cutters to increase its accuracy and cutting speed.
ALIKO, Durma, and Ermaksan hydraulic CNC press brakes
With a power of 20 kW, they can cut parts from mild steel of up to 50 mm thick and stainless steel and aluminum alloys of up to 60 mm thick. The cut precision and the resulting roughness allow to reduce or completely eliminate machining of parts and, therefore, reduce the production costs without compromising the product quality.
Double-acting hydraulic sheet-punching press (P4644)
unique equipment with a maximum force resulting from a simple action (4,000 tf). It is used to draw hot and cold molds for making elliptical bottom and calibrate and bend sheet metal parts.
VABS welding and assembly gantry
the only advanced machine of its kind, exclusively present in the Ruzkhimmash fleet only. Due to its versatility, it can be used to produce both 40- and 80-foot platform wagons at the same time. Thanks to the pneumatic clamps, the required parameters are available in a wide range. The technology allows working with variable cross-section structures up to 26 m long, which ensures the equipment reliability during operation.
Thermostal TS-205 thermal furnace with a roll-out hearth
designed for heat treatment (hardening heating, annealing) of large items, including tank shells. The use of a pull-out heathers reduces loading and unloading times and automates the heat treatment process. With internal dimensions of 16,000x4,000x4,000 mm, the furnace processes apparatuses with the maximum diameter of 3,400 mm at the maximum heating temperature of 900ºC. The multi-zone program control distributes the temperature evenly across the chamber.
