Description
Шихта порошковой проволоки на основе системы CaFa-SiOa с применением ферросплавов и железного порошка известна.The mixture of flux-cored wire based on the CaFa-SiOa system using ferroalloys and iron powder is known.
Описываема шихта порошковой проволоки отличаетс от известной тем, что в нее, с целью повышени прочности сварного соединени , вводитс MgCOs в количестве 2-8%. Остальные компоненты берутс в следуюш.ем процентном отношении:The described batch of flux-cored wire differs from the known one in that, in order to increase the strength of the welded joint, MgCOs are introduced in the amount of 2-8%. The remaining components are taken in the following percentage:
флюоритовый концентрат- 2-7%fluorite concentrate - 2-7%
полевой шпат- feldspar-
ферромарганец-0,2-0,ferromanganese-0.2-0,
ферротитан- 2-4%ferrotitanium - 2-4%
железный порошок- 7-25%iron powder - 7-25%
остальное - лента стальна низкоуглеродиста .the rest is low carbon steel tape.
Получаетс шихта на основе системы MgCOs-CaFa-SiO2. panetне известна .A mixture is obtained based on the MgCOs-CaFa-SiO2 system. panet is not known.
Положительной особенностью описываемой шихты вл етс то, что процесс сварки открытой дугой можно вести без зашитных газов.A positive feature of the described charge is that the open arc welding process can be conducted without protective gases.
Благодар низкой температуре диссоциации MgCOs и относительно высокому потенциалу его ионизации эта защита металла позвол ет примен ть малое количество газо- и шлакообразующих материалов в шихте проволоки (8-12% от веса проволоки) и достигнуть высокого коэффициента расплавлени .Due to the low dissociation temperature of MgCOs and the relatively high potential for its ionization, this metal protection makes it possible to use a small amount of gas and slag-forming materials in the wire charge (8-12% of the wire weight) and achieve a high melting ratio.
Вследствие хорошей защиты металла от воздуха, основного характера шлака и малой его газопроницаемости сварные соединени , сваренные порошковой проволокой с шихтой на основе системы MgCOa- CaF2-SiO2, имеют высокие механические свойства.Due to good protection of metal from air, the basic nature of slag and its low gas permeability, welded joints welded with flux-cored wire to a charge based on the MgCOa-CaF2-SiO2 system have high mechanical properties.
Порошкова проволока с шихтой системы MgCO3 CaF2-SiOg обладает хорошими сварочными технологическими свойствами.Powder wire with a charge of MgCO3 CaF2-SiOg system has good welding technological properties.
