    Domestic Refractory Ceramics Prevent Currency Outflow

    A domestic knowledge-based company has produced refractory ceramics that have high heat resistance and wide industrial applications

    A knowledge-based company has produced industrial refractory ceramics, which prevented a significant currency outflow from importing counterparts.

    These ceramics are used in various advanced industries and modern manufacturing processes, according to a member of the Board of Directors of Evarplast Komesh Company.

    “Using refractory ceramics in places where there is a possibility of fire or high heat can be very economical and safe [due to their higher resistance compared with metals and other materials],” Nahid Chegeni was also quoted as saying by the news portal of the Vice-Presidency for Science and Technology.

    Refractory ceramics show good resistance in environments with very high temperatures and can withstand physical wear and corrosion caused by chemical agents, hence they are used to line hot surfaces inside industrial equipment and furnaces.

    These ceramics can be used in automotive, railroad, oil, gas, petrochemical, wood and furniture, printing and packaging, textile, electrical, electronic and telecommunication industries. They are essential to petrochemical production and gasoline refining.

    Chegeni said refractory ceramics have many other features such as excellent resistance to oxidation and corrosion, high thermal insulation and mechanical resistance, low thermal expansion and excellent wear resistance.

    Refractory ceramics can show high resistance to chemical compounds, corrosion and pressures applied during the manufacturing processes. They are mainly used in industries dealing with fire, especially in industrial furnaces, as they can withstand 600-2,000 degrees Celsius.

    The company official noted that the thin industrial refractory ceramic has high torsion strength, electrical shock resistance, electrical insulation and thermal tolerance.

    “The production of refractory ceramic production has created many directly and indirect jobs,” she said, without further elaboration.

     

     

    Domestic Calibrator Increases Accuracy of Tests

    A domestic knowledge-based company has designed a calibrator that can compete with foreign counterparts.

    Calibration is the process of adjusting a device to meet the manufacturer’s specifications.

    Calibrators vary in form and function, depending on instruments with which they are designed to work.

    The criteria measured by the domestic calibrator are traceable measurement standards, according to a member of the Board of Directors of Behrad Sazan Parse Shiraz Company.

    “The purpose of calibration is to control the accuracy and precision of the metrological parameters of testing and measuring devices as well as equipment that impact the quality of the process involved,” Hossein Bostani added.

    Calibration is used to ensure that measurements conform to international standards.

    The most sophisticated industrial equipment will not be very useful unless it is calibrated.

    Through calibration, adjustments made to a piece of equipment ensure that it performs as expected and can be relied on to deliver predictable, accurate results that meet quality standards.

    Most instruments and sensors are designed to meet certain accuracy specifications and calibrators adjust the instruments to meet those specifications.

    Usually, after some time, an equipment develops a measurement error and for its correct operation, the process and system must have the necessary accuracy.

    For instance, the regular calibration of precision instruments is one of the things that must be paid attention to in industrial automation.

    Thermocouples, temperature and pressure indicators, temperature and flow transmitters, level transmitters and control valves are among other devices that can be calibrated.

    The initial calibration of a test and measurement device is carried out in the manufacturing and production stage, which can include the grading of a device, adjusting its electrical circuits, such as setting digital indicators and estimating the stability of the device. Then after some time, calibrators can be used to calibrate the devices periodically.

    “The domestic calibrator will reduce the costs of companies by half and prevent a significant currency outflow. If the necessary support is provided in the field of export, it could compete with foreign counterparts,” he said.

    Bostani noted that 20 jobs have been created in Parse Shiraz Behrad Sazan Company, which can be increased if the company starts exporting the calibrator.
