Abstract: The magnetic properties of polycrystalline samples of isotopically enriched iron with the content of isotope 56Fe 99.945±0.002 at. % were investigated. [..] Read more

Abstract: Traditional routes of ironmaking and steelmaking processes demand high-temperature preparatory steps, such as coking and sintering. These processes are of great concern since they represent a considerable environmental burden. [..] Read more

Abstract: Blast furnace slag is generated as a by-product of the metallurgical industry and can be called “multifunctional waste”. It can be used in the building industry, reused in production or landfilled. [..] Read more

Abstract: The processes of production of pig iron, steel and cast irons are accompanied by the formation of a significant amount of slag. This waste can be sent to re-smelting, however, if it contains a high content of impurity components, it is sent to the dump as waste. [..] Read more

Abstract: Hydraulic descaling is an inherent part of the hot rolling process but can sometimes also be applied in the heat treatment process, continuous casting and other processes. The need for optimal descaling is linked with the quality of the final product. [..] Read more

Abstract: The article deals with the determination of sulphur contents in different types of foundry furan no-bake reclaims from different suppliers using two different methods – combustion elemental analysis and gravimetrically. The first of these methods is the standard fast instrumental method. [..] Read more

Abstract: Iron metallurgy is one of the most iconic achievements of early human history. It surely forged the future. [..] Read more

Abstract: Granulated blast furnace slag exhibits latent hydraulic properties and its binding properties can be evoked by the addition of the alkali activator. Subsequent hydration processes during the setting and hardening processes let to origination of the solid products with the mechanical properties comparable or even better than the product obtained with ordinary Portland cement.

Abstract: Paper presents an analysis of 3D images of the composite with a polyamide (PA) matrix reinforced by short glass fibres. The aim of the study was the assessment of the orientation of the fibres. [..] Read more

Abstract: Production of new steel grades and growing demands on productivity require an increasing understanding of heat transfer during the continuous casting process. This work is focused on a mould which has a great influence on the casting process and the final quality of billets. [..] Read more

Abstract: The work is dedicated to obtaining a complex Al-Mn-Fe master alloy for precise alloying high-manganese steels with aluminum high content as well as for making additions during aluminum alloys production. The addition of aluminum large quantity to steel during steelmaking is an especially difficult task, because of the low density and melting temperature of aluminum. [..] Read more

Abstract: Non-metallic inclusions are one of the factors that influence the fatigue strength of steel. Although steel has a relatively small number of non-metallic inclusions, those impurities have a considerable impact on the material's technological and strength parameters, in particular fatigue strength and life. [..] Read more

Abstract: Using oxyfuel combustion in steel reheating provides higher throughput and substantial fuel savings. Accordingly, oxyfuel has many benefits, but also some drawbacks like hot spots in furnaces and thermal NOx generation. [..] Read more

Abstract: One of the products of pig iron production is blast furnace gas. Its pressure energy can be used, among other things, by including an expansion turbine with subsequent production of electricity. [..] Read more

Abstract: Objective of this work is to model the thermal expansion coefficients of selected steel grade and compare results with those measured by TMA method. Coefficient of thermal expansion is described as a function of steel composition (C, Mn, P, S, Si, Cr, Ni, Mo) and temperature.Experimental values are described and compared with model. [..] Read more

Abstract: The paper is focused on the design of a new technology for the production of bearing components in operating conditions. The design is compared with current technology, the essence of which is the operation of multi-spindle automats, i. [..] Read more

Abstract: The paper deal with the unconventional method of creating cavities in samples. There is also described the principle of system for creating experimental samples. [..] Read more

Abstract: Creation of new structural materials with new unique properties of metal remains one of the urgent tasks of modern materials science. In practice, it is possible to improve the properties of existing structural materials by grinding their structure to an ultra-fine-grained state. [..] Read more

Abstract: A hot flow curve approximation performed via flow stress models as well as artificial neural networks requires precisely estimated constants. This estimation is in the case of highly-nonlinear issues often solved via gradient optimization algorithms. [..] Read more

Abstract: The main goal of this study is to analyze the influence of radial-shear rolling (RSR) modes on the structure and properties of 1050A using finite element modeling (FEM) and experimental verification of the results. Ingots with a diameter of 60 mm were obtained, which were rolled into rods with a diameter of 14 mm at different regimes (total elongation ratio µ = 18.4). [..] Read more
