  • Treatment Of Steel In Its Molten State (AREA)

Description

Пример. Дл  получени  лигатуры готов т шесть смесей, имеющих различное количественное содержание кальци  и титана. Кажда  смесь сплавл етс  отдельно в открытых индукционных печах с защитой от воздуха аргоном или фторидным флюсом.Example. To obtain ligatures, six mixtures are prepared with different quantitative contents of calcium and titanium. Each mixture is fused separately in open induction furnaces with air protection with argon or fluoride flux.

Химический состав лигатур и свойства обработанной ими стали приведены в таблице.The chemical composition of the ligatures and the properties of the steel treated by them are given in the table.

Испытание на износостойкость провод т путем перемещени  двух кольцевых образцов на длину 10 мм при удельном давлении 300 кгс/см. Коррозионную стойкость определ ют в кип щей 55%-ной азотной кислоте в течение 24 ч. Наличие следов межкристаллитной коррозии при испытании не вы влено.A wear resistance test was carried out by moving two ring specimens over a length of 10 mm at a specific pressure of 300 kgf / cm. Corrosion resistance is determined in boiling 55% nitric acid for 24 hours. No trace of intergranular corrosion has been detected by testing.

Использование предложенной лигатуры позвол ет -повысить срок службы и надежность работы оборудовани , например клиновых задвижек в различных средах химического производства.The use of the proposed ligature makes it possible to increase the service life and reliability of the equipment, for example, wedge gate valves in various chemical production environments.
