Intensification of production at Cherepovets steel mill (1987)

Foundry production at the Cherepovets Metallurgical Combine.

Unloading of iron ore concentrate.

Coke chemical production of the plant.

Dry quenching of coke.

Hot coke from coke batteries is fed to the USTK (dry coke extinguishing plant).

A cartoon explaining the operation of such an installation.

The heat generated by the installation is used to generate steam, and its pressure is used to generate electricity at the turbine generator.

For the first time in world practice, an industrial installation for calcination and dry quenching of pitch coke has been created.

Blast furnace production.

Over the decade, all blast furnaces were reconstructed.

New cast-iron letka.

Air tuyeres in the furnace.

A worker watches the melting process.

Liquid metal is released from the blast furnace.

Performance indicators of the Cherepovets Metallurgical Combine.

The world's largest blast furnace No. 5, equipped with the most modern equipment.

All the vital centers of the huge plant are connected to computing complexes based on microprocessor technology.

The main technological processes are controlled by local automated systems. united in the automated control system.

The information is displayed on the display in a form convenient for technologists.

600-ton mixer-type buckets are used for the transportation of liquid cast iron.

Powerful mixers have more than halved the heat loss.

This facilitated the smelting of convector steel from low-manganese cast iron with a reduced silicon content.

Ladle for filling liquid metal.

Control room of the converter shop.

At the end of the drain, the slag is cut off by the manipulator.

Instrument readings.

All metal is purged at the argon plant and poured in a continuous way.

Continuous casting machines are equipped with an automatic control system.

In the electric steelmaking shop, the technology of smelting corrosion-resistant steel in heavy-duty electric furnaces has been mastered.

Casting of corrosion-resistant steel is carried out on continuous casting machines.

Shop of rolling production.

A wire mill for large-section blanks operates in the rolling mill.

The mill is equipped with horizontal prestressed crates.

The small-grade mill 250 is equipped with horizontal and vertical crates of this type.

Accelerated cooling of rolled products in the stream has been introduced here, metal losses in scale have been reduced.

Mill 2000 in the sheet rolling shop, one of the most equipped and high-performance broadband hot rolling mills in the country.

Supporting elements of slabs, raiders.

Special alloys for raiders and a new technology for their production were developed.

The durability of the raiders has increased and the quality of the slabs has improved.

The mill 2000 has mastered the production of rolled sheets of reduced thickness with guaranteed strength.

This is achieved by using an inter-cage cooling system and introducing controlled rolling to obtain the required temperature regime at its end.

Transportation of rolled products on the shop floor.

Cold rolling shop.

Loading rolls with rental.

The head part of continuously etching units.

Joint welding machine.

X-ray thickness gauges are installed on the 1800 mill.

Automatic system for adjusting the tension and thickness of the strip.

Rolls with sheet steel.

Hot continuous galvanizing unit.

Galvanized steel rolls.

Shop of bent profiles.

The technology of production of welded closed profiles has been mastered.

The operator watches the welding.

The pre-formed profile is supplied for longitudinal welding.

The edges are heated by a high-frequency current, while compression occurs.

The profile is calibrated in the correct crates and cut with a flying saw in the stream.

Restoration and strengthening of rolling rolls.

Working and supporting rolls are restored by the method of electric arc surfacing.

Plasma surfacing has been introduced.

Specialized sites have been created in repair shops.

Highly alloyed powder materials are used for surfacing.

Plasma-mechanical processing of metal.

Plasma cutting and welding.

Plasma and gas thermal spraying.

Samples of the restored instrument.

Turning works.

Metal is pouring from the blast furnace.
