Abstract

Способі позапічної обробки сталі, що містить в собі розкиснення сталі алюмінієм і введення в сталерозливний ківш матеріалів, що містять в собі кальцій, перед введеням матеріалів, що містять в собі кальцій, визначають кількість алюмінію і вуглецю в розплаві, а витрати матеріалів, що містять в собі кальцій, в перерахунку на усвоєний металом кальцій, установлюють із співвідношеня [Ca] = (0,14...0,18) [Al] при кількості вуглецю до 0,17% і із співвідношення [Ca] = (0,10...0,14)[Al] при кількості вуглецс більш 0,17%. При цьому як матеріали, що містять в собі кальцій, використовують силікокальцій в вигляді порошкового дроту.The method of out-of-furnace treatment of steel containing deoxidation of steel with aluminum and the introduction into the steel ladle of materials containing calcium, before the introduction of materials containing calcium, determine the amount of aluminum and carbon in the melt, and the cost of materials containing calcium itself, in terms of assimilated metal calcium, set from the ratio [Ca] = (0.14 ... 0.18) [Al] at a carbon content of up to 0.17% and from the ratio [Ca] = (0.10 ... 0,14) [Al] when the amount of carbon is more than 0.17%. In this case, as materials containing calcium, use silicocalcium in the form of flux-cored wire.
