Reference materials (RM) are samples that are used to set up and calibrate optical emission spectrometers. RM samples should be completely homogeneous in terms of chemical composition and have the least amount of alloying element segregation.
These samples are produced by special casting methods and techniques that are needed to produce homogeneous samples with minor segregation of alloying elements.
Razi Metallurgical Research Center (RMRC) has been the first and the only manufacturer of reference materials to produce these samples inside the country since2003 and in 2017 and 2018, it also succeeded in registering patents for the production of steel and non-ferrous reference materials.
At present, the range of alloys produced is much wider and includes a wide range of industrial alloys such as carbon steels and stainless steel, manganese steel, grey and ductile cast irons, Ni -resist and Ni-hard cast irons, Brass and bronzes, aluminum alloys, zinc based alloys and super alloys.
The samples are analyzed with different methods and after examining the chemical and structural composition of the product and ensuring the precision of its chemical composition and homogeneity, the certificate is issued for each sample.
The production of these samples is carried out using medium frequency induction furnaces with capacities of 5 and 25 kg, as well as Vaccum induction melting furnaces of 5 kg capacity and electromagnetic stirrer in special molds, which according to the design technology used, is possible to ensure the uniformity and homogeneity of the samples.
