Abstract
The composition of coverflux contains (wt) SiO2 10%-20%, Al2O3 1%-5%, CaO 50%-60%, MgO 5%-12%, Fe2O3 1%-3%, MnO 0.01%-0.1% and fixed carbon 0%-1%. Said coverflux possesses proper melting point and good heat-insulating property, can prevent secondary oxidation of molten steel, and can prolong ladle life.
Description
The present invention relates to a kind of ladle covering agent, particularly relate to a kind of alkaline granule steel ladle covering agent.
General ladle covering agent generally adopts the tart insulating covering agent at present, and this kind insulating covering agent contains high SiO
2Though have heat-insulating property preferably, cause the secondary oxidation of molten steel easily, the Al in the molten steel
2O
3Inclusion content improves, and acid insulating covering agent slag can corrode the anti-material of alkaline ladle.
What the purpose of this invention is to provide a kind of alkalescence has that fixed carbon content is low, low, the initial Al of reducible oxide-based composition content
2O
3The alkaline granule steel ladle covering agent that content is low, basicity is high.
Technical scheme of the present invention is a kind of alkaline granule steel ladle covering agent of design, and it is characterized in that: the Chemical Composition of insulating covering agent (by weight) contains SiO2 10%~20%, Al
2O
31%~5%, CaO 50%~60%, and MgO 5%~12%, Fe
2O
31%~3%, MnO 0.01%~0.1%, fixed carbon 0%~1%.
Advantage of the present invention is that the fusing point of insulating covering agent is suitable, and three layers of melting structure be controlled to have heat retaining property preferably, can prevent secondary oxidation of steel, Al in the absorption molten steel
2O
3The inclusion ability is strong, can or not corrode the alkaline anti-material of ladle to molten steel recarburization, helps prolonging the bag age of ladle.
Below in conjunction with embodiment the present invention is elaborated, Chemical Composition (by weight) meter of insulating covering agent is got SiO
220 kilograms, Al
2O
35 kilograms, 60 kilograms of CaO, 12 kilograms of MgO, Fe
2O
32.7 kilogram, MnO0.1 kilogram, 0.2 kilogram of insulating covering agent that is mixed into 100 kilograms of fixed carbon, the oven dry of granulation (particle of 10mm*5mm) back, screening back packing.The fusing point of this insulating covering agent is suitable during use, and three layers of melting structure are controlled, has to be incubated rerum natura preferably, because reducible oxide-based composition content is low, can prevent secondary oxidation of steel, because Al
2O
3Content is low, Al in the absorption molten steel
2O
3The inclusion ability is strong and carbon content is low can because insulating covering agent is an alkalescence, can not corrode the alkaline anti-material of ladle to molten steel recarburization, helps prolonging the bag age of ladle.
