Refractory materials
Refractory materials are used in the ironworks and foundry industry, in the manufacture of cement and bricks, in thermal power plants and in heating plants. They are also intended for the construction of household furnaces and fireplaces.
COMET's product range also comprises appropriate supplementary materials for installation and maintenance, such as glues, mortars and putties.
They are produced on the basis of aluminate raw materials and heat resistant to 1800° C.

Lateral testing machine
In 2005, the OSA (Organization for the Safety of Abrasives) tightened its requirements with a new regulation requiring additional testing for all cutting-off and grinding wheels marked with the OSA symbol. In addition to the breakage test, products now also need to be subjected to the testing of single and three-point lateral loads and the impact test.
COMET has produced the first prototype of a testing machine, which is also intended for sale on the market. Potential customers may view it in operation at our company.
This machine makes it possible to perform all the prescribed tests in compliance with OSA requirements:
- single-point product loading for dimensions from Φ 115 to Φ 400 mm,
- three-point product loading for dimensions from Φ 300 to Φ 400 mm
- product impact test for dimensions from Φ 115 to Φ 400 mm
During the pendulum impact test, the product is tested for impact by a pendulum that has a certain weight and is lowered from a certain height, thus releasing energy upon impact. The product is required to sustain the prescribed impact energy.
All test results are automatically recorded in an industrial-grade personal computer, which is also prescribed. Automatic transfer of the results of testing to the company's central business system is also possible to achieve more permanent archiving of data and enabling access to this data for further processing.
