Задача изобретения состоит в повышении прочности стали.The objective of the invention is to increase the strength of steel.
Технический результат достигается том, что сплав для раскисления, легирования и модифицирования стали, содержащий кремний, кальций, титан, бор, азот, ванадий, молибден, железо, дополнительно включает цирконий, алюминий и ниобий, при следующем соотношении компонентов, мас.%: кремний 4,0-8,0; кальций 0,5-1,0, титан 16,0-20,0; бор 4,0-8,0; азот 0,1-0,2; ванадий 4,0-8,0; молибден 10,0-12,0; цирконий 4,0-8,0; алюминий 4,0-8,0; ниобий 4,0-8,0; железо - остальноеThe technical result is achieved in that the alloy for deoxidation, alloying and steel modification containing silicon, calcium, titanium, boron, nitrogen, vanadium, molybdenum, iron, additionally includes zirconium, aluminum and niobium, in the following ratio, wt.%: Silicon 4.0-8.0; calcium 0.5-1.0, titanium 16.0-20.0; boron 4.0-8.0; nitrogen 0.1-0.2; vanadium 4.0-8.0; molybdenum 10.0-12.0; zirconium 4.0-8.0; aluminum 4.0-8.0; niobium 4.0-8.0; iron - the rest
В таблице приведены составы сплава.The table shows the alloy compositions.
Сплав для раскисления, легирования и модифицирования стали может быль выплавлен, например, в индукционных электропечах (ИСТ-0,06, ИСТ-0,16 и др.). Основное сырье для выплавки сплава: ферробор (ФБ2), ферротитан (Тн0), ферромолибден (ФМ3), молибдат кальция, феррованадий (ВД1), ферроцирконий, лом изделий из сплавов АЛ2, АЛ4, Д-31.The alloy for deoxidation, alloying and steel modification could be melted, for example, in induction furnaces (IST-0.06, IST-0.16, etc.). The main raw materials for smelting the alloy: ferroboron (FB2), ferrotitanium (Tn0), ferromolybdenum (FM3), calcium molybdate, ferrovanadium (VD1), ferrozirconium, scrap products from alloys AL2, AL4, D-31.
Сплав в нагретом не ниже 400°С состоянии вводят в начале кипения стали, выплавляемой мартеновским кислым способом (основное сырье для выплавки стали: стальной лом и передельный чугун). Расход сплава 1,0-1,5% от общей массы выплавляемого металла. Корректировку производят не позднее чем за 25-30 мин до выпуска стали из печи. При выпуске из плавильной печи стали, обработанной сплавом, ее температура должна составлять 1550-1570°С.Alloy in a heated state not lower than 400 ° С is introduced at the beginning of boiling of steel smelted by the open-hearth acid method (the main raw materials for steel smelting are steel scrap and pig iron). Alloy consumption is 1.0-1.5% of the total weight of the smelted metal. The adjustment is made no later than 25-30 minutes before the release of steel from the furnace. When the steel processed by the alloy is released from the melting furnace, its temperature should be 1550-1570 ° С.
Сталь марки 33 ХС до обработки сплавом имеет предел прочности на растяжение 90 кг/мм2, после обработки сплавом (расход 1%) - 93-95 кг/мм2. Сталь марки 38 ХС до обработай сплавом имеет предел прочности на растяжение 95 кг/мм2, после обработки сплавом (расход 1%) - 99-103 кг/мм2. Сталь марки 20 ХГСА до обработки сплавом имеет предел прочности при растяжении 80 кг/мм2, после обработки сплавом - 84-86 кг/мм2.Steel grade 33 XC before alloy treatment has a tensile strength of 90 kg / mm 2 , after alloy treatment (consumption 1%) - 93-95 kg / mm 2 . Steel grade 38 XC before the alloy treatment has a tensile strength of 95 kg / mm 2 , after alloy processing (consumption 1%) - 99-103 kg / mm 2 . Steel grade 20 HGSA before alloy treatment has a tensile strength of 80 kg / mm 2 , after alloy treatment - 84-86 kg / mm 2 .
