Justification of the Production Technology Efficiency for High-Strength, Low-Alloy Steels with Improved Properties and Quality at Low Cost. Part 3. Production of Rolled Products from Transitional Slabs
We study metal samples taken from two batches of hot-rolled, semi-finished steel products and two batches of grade HC340LA cold-rolled steel, annealed in bell-type furnaces, produced from transitional slabs obtained by continuous casting of the developed high-strength, low-alloy, microalloyed, auto-...

Summary: | We study metal samples taken from two batches of hot-rolled, semi-finished steel products and two batches of grade HC340LA cold-rolled steel, annealed in bell-type furnaces, produced from transitional slabs obtained by continuous casting of the developed high-strength, low-alloy, microalloyed, auto-sheet steel microalloyed with titanium (Ti) onto steel microalloyed with niobium (Nb). Based on the results obtained, for the first time, the possibility of continuous casting of the developed high-strength, low-alloy, auto-sheet steel microalloyed with Ti onto steel microalloyed with Nb is established. It is revealed that both grade S420MS hot-rolled steel according to EN 10149 and grade HC340LA cold-rolled steel, annealed in bell-type furnaces, can be simultaneously produced from transitional slabs while meeting EN 10268 requirements with reduced costs. |
