Description
Целью изобретени вл етс понижение угара ванади , снилсение температуры плавлени лигатуры и повышение механических свойств сталей, особенно их хладостойкости. Это достигаетс тем, что в предлагаемый состав ванадийсодержащей лигатуры дополнительно введен кальций при следующем соотношении компонентов, вес. %:The aim of the invention is to reduce vanadium carbon monoxide, lower the melting temperature of the master alloy and increase the mechanical properties of the steel, especially its cold resistance. This is achieved by the fact that calcium in the proposed composition of the vanadium-containing ligature is additionally introduced in the following ratio of components, wt. %:

Лигатуру присаживают в жидкую сталь в расчетном количестве в процессе плавки или выпуска в ковш,The ligature is placed in molten steel in the calculated amount during the smelting or release process into the ladle,
В процессе растворени лигатуры в жидком металле ванадий, азот, титан и углерод образуют питриды и карбонитриды ванади и титана , которые при заданном соотношении компонентов обеспечивают получение необходимых гарантируемых механических и эксплуатационных характеристик стали. Введение кальци в лигатуру необходимо дл получени стали повышенной хладостойкости.In the process of dissolving the master alloy in the liquid metal, vanadium, nitrogen, titanium and carbon form vanadium and titanium pitrides and carbonitrides, which, with a given ratio of components, provide the necessary guaranteed mechanical and operational characteristics of the steel. The introduction of calcium into the ligature is necessary to obtain high cold-resistant steel.
Примером может служить сталь марки 20 Г1ФЛ, раскисленна и легированна разработанной лигатурой, содержащей 0; 0,05; 2,5; 5,0 п 8,0% Са. Плавка стали производитс в 300-килограммовой индукционной печи, лигатура вводитс в ковш пофракционно.An example is steel grade 20 G1FL, deoxidized and alloyed developed ligature containing 0; 0.05; 2.5; 5.0 p 8.0% Ca. The steel is smelted in a 300 kg induction furnace, the ligature is introduced into the ladle in fractional form.
Механические свойства при различном содержании кальци в лигатуре, полученные на образцах, вырезанных из стандартных трефо20 видных проб, приведены в таблице.The mechanical properties for various amounts of calcium in the ligature obtained on samples cut from standard trefo 20 samples are given in the table.
Из таблицы видно, что присадка в сталь 20Г1ФЛ лигатуры оптимального состава (2,5% Са) позвол ет подн ть ударную в зкость при -60°С на 40%. Повышение содержани кальци выше 5% не приводит к дальнейшему повышению хладостойкости стали.From the table it can be seen that the additive in steel 20G1FL of the ligature of optimal composition (2.5% Ca) allows the impact strength to be raised at -60 ° C by 40%. An increase in the calcium content above 5% does not lead to a further increase in the cold resistance of the steel.
