Технология производства и исследование качества сверхтолстых листов высокопрочной конструкционной стали АБ2Р, изготовленных из крупных кузнечных слитков

Abstract

The manufacturing technology was tested and the quality study of super-thick sheets made of highstrength structural cold-resistant steel AB2R made from large ingots was carried out. Ingots are poured with siphon using modern pouring and heat-insulating mixtures while protecting the metal with argon. The use of the developed technology for casting large ingots together with the use of out-of-furnace refining and metal modification with aluminum and calcium provides a high level of quality of super-thick rolled products.
