The Institute of Metal Technology offers customers components made of chromium wear-resistant cast iron for centrifugal crushing and grinding equipment and applications in the construction industry under a manufacturing agreement, the technology for their manufacture under a commercial agreement with technical assistance and/or a licensing agreement, and is looking for partners interested in a distribution services agreement.

Abrasive wear is the main cause of failure of machine parts and mechanisms in the mining, construction, road and agricultural industries. Most parts of crushing and grinding equipment operate under shock loads (the size of the initial grinding particles is 20-5 mm), therefore, chromium cast iron is required to work under such conditions, which has high values ​​of impact strength and wear resistance.

On the basis of technologies developed at the Institute, the following can be manufactured:
1. Impact plates
- A slab 50×50×90 mm weighing 1.8 kg is cast into a sand mold from XTS, followed by heat treatment to increase hardness.
Hardness 61 - 64 HRC, impact strength KC 8 - 12 J/cm2.
- Slab 70×70×140 mm weighing 5.3 kg, cast in a combined mold:
the lower part is a metal plate, the upper part is made of XTS.
Used without heat treatment.
Hardness from below 59 - 62 HRC, from above - 52 - 56 HRC.
- A slab 85×85×180 mm weighing 9.8 kg is cast into a metal mold with a sandy top part.
Used without heat treatment.
Hardness of all surfaces 59 - 62 HRC, impact strength KC 8-10 J/cm2.

2. Cones, bead mill disks, funnels, inlet rings, backing sheets, etc.

3. Replaceable parts of mixers according to customer drawings for mixing concrete and other building mixtures, including mixer blades, auger knives, etc.

The compositions of the IChKh18VM, IChKh18VN, IChKh18G2VM, and 450Kh18VFMNB cast irons (patent BY 23010) have been developed, as well as technologies for their casting in combined and metal molds (chill molds), as well as technical specifications for castings made from heat-treated wear-resistant chromium cast irons. The technology for casting parts from chromium cast irons into metal and combined molds best meets modern requirements for resource conservation and the quality of manufactured parts.

The use of alloyed steel scrap ensures the production of alloying elements such as chromium, nickel, vanadium, tungsten, and molybdenum.

Cast parts made from wear-resistant chromium cast irons are intended for crushing units of centrifugal crushers and mills, construction equipment, shot blast machines, and are also used by mineral processing plants and construction companies.

Technical advantages (compared to the best domestic and foreign analogues).

The casting technology ensures the production of a finely dispersed chromium cast iron structure. Compared to analogues available on the Belarusian and Russian markets, parts made from chromium cast irons developed at the Institute of Metal Technology of the National Academy of Sciences of Belarus exhibit increased wear resistance and can increase the durability and reliability of parts and equipment operating under intense abrasive conditions. They are characterized by a long service life, with the operating time of such parts being 1.5–2 times longer than that of existing analogues. The use of alloyed steel scrap reduces the cost of production by 10–15%. The achieved performance indicators are comparable to the best global analogues, which provides the basis for the further promotion of cast consumables in the markets of the Republic of Belarus, the Russian Federation, and neighboring countries.

The Institute of Metal Technology completed a research project, "A Study of the Complex Effect of Alloying and Heat Treatment on the Structure and Performance Properties of High-Wear-Resistant Chromium Cast Irons." The results of this research were used in the development of the technology.
