The steel market in Poland has increased over the last few years in the market economy. Domestic steel producers manufacture more crude steel and steel products. The consumption of steel increases more and more every year. The value of shipments from the Polish steel sector account for approx. 3% of industrial production. The Polish economy uses and processes over 8 million tonnes of steel (apparent consumption of crude steel/semi-products) yearly (average volume of steel consumption from 2000 to 2017). The largest user of crude steel is metal good, but the largest user of finished steel products is construction (more than 40%), followed by: machinery industry (15%), automotive (about 12%), transport equipment (4%), home appliances industry (3.5%) and other industry sectors, e.g. electrical equipment, electronics. Changes in domestic steel consumption are presented in the paper. The publication presents the historical trends and forecasts of quantity (volume) of steel consumption. The analysis of steel intensity was realised on the basis of apparent consumption of steel in device on: semi-products and finished steel products. Realised analysis is the base for building of scenarios of steel production by particular sectors of industry in Poland.
Industry 4.0 is a collective term meaning the integration of intelligent machines and systems, and the introduction of changes in production processes, aimed at increasing production efficiency and introducing the possibility of flexible changes in the assortment of products. Industry 4.0 is focused on the continuous improvement of manufacturing processes through the use of self-learning robots and personalized production. The aim of the article is to identify key directions of improvement of the heat treatment process of cylindrical products in the context of applications of Industry 4.0 solutions. The analysis of individual stages of the heat treatment process using an example of a metallurgical company became the basis for determining key organizational and technical problems at individual stages of product manufacture.
