DOI: https://doi.org/10.37904/metal.2019.798, 187-193
Abstract:
Blast furnace gas, which is created as a by-product during the ironmaking, belongs to the less valuable fuels due to its low heating value. Due to BF gas parameters (high amount of gas and high content of CO), it is used as an energy source for the preparation of preheated air in the stoves or for the heating of industrial furnaces. [..]

Abstract:
Quantitative methods for determining the contamination of non-metallic inclusions (NMI) steel can be divided into metallographic, physicochemical or chemical. The quality control of steel in the metallurgical industry mostly uses a method in which their microstructure is observed on undigested destruction. [..]

Abstract:
The vast majority of metals and alloys used in technical practice are produced from a liquid state - a liquid metal. A most important phase transformation at steelmaking process is crystallization of steel (phase transformation of liquid steel from liquid to solid state) and process of own solidification of steel.

Abstract:
The influence of the cooling rate immediately before hot working on the flow stress and microstructure of δ ferrite-austenite duplex stainless steel (25 % Cr duplex stainless steel) was investigated by a hot compression test at 1,000 – 1,200 °C with various strain rates (0.1 to 10.0 s-1). In spite of the fact that the compression temperature was the same, the condition of rapid cooling immediately before the hot compression test greatly reduced the maximum flow stress σmax and work-hardening coefficient n values.
