Ductile iron indicator ICh-21










Linked profile in other language
Larisa Zezetko
The Institute of Applied Physics offers consumers an indicator for the rapid determination of the type of cast iron ICh-21 directly in castings under a manufacturing agreement and is looking for partners to conclude a distribution services agreement.
The ICH-21 indicator ( in Russian) is designed to quickly determine the type of cast iron (high-strength or gray) directly in the castings. The principle of operation of the indicator is based on comparing the results of the inspection of the casting by the indicator with the actual size of the casting, measured, for example, with a caliper.

Structurally, the Indicator is made in the form of an electronic unit and two sensors.
To conduct an examination, it is enough to attach the indicator sensors to the casting.
Information about the results of the casting inspection is presented on a liquid crystal display and LED indicators.
Casting preparation for inspection requires only shot blasting to remove scale. It is possible to inspect castings even after applying the primer, even if it has not yet dried.
Checking the performance of the indicator is carried out using a sample of the indicator included in the kit.
The indicator is designed to work in a workshop in offline mode, powered by a built-in battery or AC adapter.
The indicator is supplied in a protective case.


The minimum thickness of the cast iron billet at the control point
10 mm
 The maximum thickness of the cast iron blank at the control point  200 mm
 Supply voltage 4.8 ±1.5 V
 Maximum continuous operation time after full charge
good batteries without recharging
 8 hours

Areas of application - metallurgical production of high-strength cast iron, input and output non-destructive testing at machine-building enterprises.

Additional comments
The main scientific fields of the Institute:
- Physics of non-destructive testing;
- Development of methods and means of non-destructive testing and technical diagnostics of materials, products and technological processes;
- Creation of scientific foundations of information technologies for non-destructive testing and technical diagnostics.

Non-destructive testing methods developed at the institute:
- Methods of ultrasonic flaw detection, structuroscopy, thickness measurement of surface hardened layers;
- Capillary control method;
- Pulse magnetic control method;
- Methods of magnetic thickness measurement of coatings;
- Thermopower method;
- Eddy current methods of flaw detection and structuroscopy;
- Method of magnetic noise structuroscopy;
- Methods for monitoring the magnetic characteristics of soft magnetic materials, magnetic fields and residual magnetization;
- Methods of radio wave flaw detection, structuroscopy, thickness measurement;
- Contact-dynamic method for monitoring the physical and mechanical characteristics of materials;
- Methods of image reconstruction in x-ray tomography.

Solved applied tasks:
- Control of defects in the continuity of parts, blanks and structural elements (defectoscopy);
- Control of the structure and physical and mechanical characteristics of materials;
- Control of the geometric parameters of products, coatings and surface hardened layers;
- Control of the stress-strain state of metal structures;
- Technical diagnostics of objects.

Applied developments of the institute are characterized by a wide range of scientific and technical problems to be solved, which are of a diversified nature, and the developed modern methods and means of non-destructive testing and technical diagnostics are used in energy, space technology, metallurgy, auto, tractor and agricultural engineering, motor building, construction , welding industry, electronics, petrochemistry, railway and road transport, pipeline transport, bridge building, aircraft building, repair services, utilities, medicine, sports, forensics, etc.

The institute has two laboratories accredited by the State Standard of the Republic of Belarus: a testing laboratory for non-destructive testing and a verification laboratory.

Objects of control - Parts, blanks, castings, rolled products, forgings, welded joints, building and other structures made of metal, concrete, plastics, composite materials, pipelines, boilers, tanks, metal structures of hoisting and transport machines, products made of rubber materials, foundations, road coatings, machines and mechanisms, electrical machines, etc.

The Institute of Applied Physics is the only academic institute both in the Republic of Belarus and abroad that specializes in the field of physics of non-destructive testing and technical diagnostics. The results of research on the development of the scientific foundations of the theory of magnetism, electromagnetic, ultrasonic, radio wave, contact-dynamic, capillary and other methods of non-destructive testing brought fame to the institute. Scientists of the institute have created dozens of new types of methods and means of control, protected by copyright certificates and patents from the leading countries of the world, introduced at many industrial enterprises of the republic and abroad. The Institute maintains active international relations, being one of the founders of the World Federation of Non-Destructive Testing Centers (the headquarters of the World Federation is located in the USA). Representatives of the Institute traditionally head the Belarusian Association of Non-Destructive Testing and Technical Diagnostics, which is part of the European Federation of Non-Destructive Testing (EFNDT).
