熔渣的氮容量及氮在渣氣和渣鋼中的分配

Nitride Capacity of Fluxes and Nitrogen Distribution Ratio at Slag-Gas and Slag-Steel Equilibrium

摘要: 用鉑坩堝測定了熔渣氮容量。在大氣條件下,測得(質量分數/%)10CaO-33BaO-49Al₂O₃-8TiO₂和54CaO-21Al₂O₃-6MgO-6SiO₂-13CaF₂2種渣系的氮容量分別為10^-6和10^-5次方數量級。采用氧化鎂坩堝測定了氮在鋼與爐外精煉常用渣之間的分配系數。

Abstract: The nitride capacities of fluxes were detemined by application of platinum crucible.The nitride capacities of slag No. 1(10CaO-33BaO-49Al₂O₃-8TiO₂) and slag No.2(54CaO-21Al₂O₃-6MgO-6SiO₂-13CaF₂) are respectively the orders of 10^-6 and 10^-5 under the condition of atmosphere. The nitrogen distribution ratio between steel and the slag No. 2 was determined by application of MgO crucible.
