Metrology and Measurement Systems
EN Measurement system analysis (MSA) was used for estimation of hardness (HBS) measurement system capability. The time dependence of capability was evaluated. Experimental material Cu-Zn-Al cast alloy was used as shape memory alloy. The average and range method with 2 appraisers, 10 samples and 3 trial[...]

Metrology and Measurement Systems
EN A Brinell hardness tester with carbide and steel balls was calibrated and thereafter the hardness of ten samples of steel STN 41 1600 was measured by four appraisers. The uncertainty of calibration and of the hardness measurement were calculated. The results obtained with carbide and steel balls wer[...]

EN The melting of steel or cast iron is one step of the foundry process. The foundry industry uses different types of furnaces, and metallurgical slags are products of the pyrometallurgical processes defecting in these furnaces. Furnace slag is a non-metallic by-product that consists primarily of silic[...]

EN Blast furnace and cupola furnace are furnace aggregates used for pig iron and cast iron production. Both furnace aggregates work on very similar principles: they use coke as the fuel, charge goes from the top to down, the gases flow against it, etc. Their construction is very similar (cupola furnace[...]
