Abstract
The present invention relates to a patching material for air brick of steel ladle, and is characterized by that the air brick is covered with a layer of repairing material, at the same time of ensuring its air permeability the life of air brick can be prolonged so as to make all the materials of steel ladle are synchronously damaged, and can be synchronously removed and repaired.
Description
Material for repairing air brick of steel ladle belongs to the steel-making refractory materials.At present, air brick of steel ladle is because the static pressure of molten steel makes airway obstruction, the erosive wear and the erosion action of molten steel and molten slag vigorous stirring, and the wearing and tearing of the temperature action of gas when being blown into make gas permeable brick and around refractory materials formation pit, the core brick deteriorates seriously, causes the life-span lower.Material for repairing air brick of steel ladle of the present invention then can solve the problems referred to above.
Core of the present invention is to adopt the form of spray repair to mend on gas permeable brick brick core and anti-material thereof on every side, utilizes the of short duration sintering of ladle waste heat to come into operation.After filling the our factory material for repairing air brick of steel ladle, when can guarantee its permeability, prolong the gas permeable brick life-span, make each position material of ladle on the basis of improving the life-span, damage is synchronously overhauled synchronously, reaches the coupling purpose that satisfies technological process.
The main thought of material for repairing air brick of steel ladle is to add composite additive, makes to expect can produce the perforation pore behind the sintering, can gas-pervious effect thereby reach.Proportioning raw materials such as following table:
| Material name | Electrosmelted magnesite clinker | The magnesium chromium powder | Tripoly phosphate sodium STPP | Sodium hexametaphosphate 99 | The silicon ash | Composite additive |
| Content (%) | ????73 | ????10 | ????2.5 | ????1 | ???2 | ????11.5 |
Adopt the method for semi dry gunning that air brick of steel ladle is repaired, test in Wuhan Iron and Steel Plant one, three steel-making respectively, effect is remarkable, produces a desired effect substantially.At present, entered the technical specialist of Wuhan Iron and Steel Plant company and evaluated the stage, and applied.
