Antiabrasion materials


Description

Abrasion and erosion are the dominant wear mechanisms in many areas of industry which shorten the life of expensive mechanical parts and equipment. Abrasion wear resistance and ability to withstand complex mechanical stress is often a requirement. Finding a materials resistant to erosion and cost-effective prices for industrial use are very important items in term of realization planning and economicla efficiency of powerplants, quarries, mines and many other industrial systems.

Testing of material resistance to strong abrasion made by our company in cooperation with the Faculty of Mechanical Engineering in Belgrade showed that "MM antiabrasive" provides much longer durability and abrasion resistance compared to other materials under extreme conditions of continuous wear and scratching material. Abrasion resistant alloys MM antiabrasive is a new product from the point of view of production technology as well as the obtained chemical and physical properties that allow high resistance to erosion (abrasion). High abrasion resistance is the result of a relatively soft and flexible base that keeps very hard carbides. MM antiabrasive is made of abrasion resistant cast iron alloy that has a significantly better properties than other materials in use, along with a favorable cost price.

Exploitation and laboratory testing of erosion resistance alloys and correlation with the microstructural characteristics and mechanical properties are made in order to compare with other antiabrasion materials. As outsiders in the study were engaged proffesors from the Faculty of Mechanical Engineering in Belgrade (Department of Mechanical Materials). In order to carry out physical and chemical analyzes the best experts in Serbia in the field of materials and erosion/abrasion thermally loaded material were hired. It was confirmed that our alloy substitute products made of basalt, ceramic, metallic coated products, austenitic steel, manganese steel, carbon steel, but with better effects of antiabrasion protection. Our alloy has longer service life and averagely lower tehnology price in producing (casting) of fabricated metal products and significantly lower price than ceramic.

Types of products by type of abrasion and areas of application

Development of several types of products is planned according to the type of abrasion and areas of application, based on validated customer requirements, experimental laboratory research, effective and efficient production based on demand and the mass ratio.

MM antiabrasive is proved to be the best solution in all industries where occurs wear of equipment driven by the abrasion. Our knowledge and experience based on a number of successful applications will also help you to work more economical, safer and with less downtime.

The test results in relation to steel Č0361

The test results in relation to steel Č0361:  Erosion causes a significant reduction of the equipment life when operating the coals with a high content of mineral material remaining in the ash. It is expressed in parts of the plant for delivery, preparation and combustion of fuels in power plants (blinds of air-mixture channels). In solving the problem of blinds erosive wear that direct windflaw with coal dust particles in power plant furnaces, were carried out laboratory and experimental research and followed the product in use.

 

The results are as follows:

Blinds of air-mixture channels in "Thermal power plants Nikola Tesla" - branch TENT B (material: Č0361, time work: 3 months)


Blinds of air-mixture channels in "Thermal power plants Nikola Tesla" - branch TENT B (material: MM antiabrasive, time work: 3 months)


Blinds of air-mixture channels in "Thermal power plants Nikola Tesla" - branch TENT B (material: MM antiabrasive, time work: 6 months)


Blinds of air-mixture channels in "Thermal power plants Nikola Tesla" - branch TENT B (material: MM antiabrasive, time work: 16 months)

Advantages of MM antiabrasive compared to antiabrasive materials

Advantages of MM antiabrasive compared to antiabrasive materials which exists on market:

  • Substitute products made of basalt, ceramic, metallic coated products, austenitic steel, manganese steel, carbon steel, where are necessary 1,5-2 times smaller amount of alloy to achieve the same or better effects antiabrasion protection.

  • Significantly lower product costs from the standpoint of the purchase and installation price and exploitation costs. Lower cost price (production) then the price of metal materials which are less resistant to erosion and significantly lower price than the basalt and ceramic from which our alloy also has a greater resistance to erosion. Stopping, halt and restart of industrial transport systems may be much more expensive than the price of the product - worn parts that change and install.

  • An alloy is a homogeneous structure and has appropriate lower macro-hardness which ensures its good technology and metallurgy workability. Machining to tight tolerance measures made possible by procedures of turning, milling, polishing, etc.

  • The alloy is more resistant to abrasion than existing materials in use. Exploitation and laboratory testing of erosion resistance alloys, correlation with the microstructural characteristics and mechanical properties are made in order to compare with other antiabrasion materials (basalt, ceramic, metallic coatings, austenitic steels, Mn-steels and carbon steels).

  • The alloy is very environmentally friendly, non-toxic and it is possible to 100% recycling (compared with basalt and ceramic which are toxic).
