Abstract
The invention relates to the technical field of metallurgical refractory materials, and particularly relates to a refractory castable for a steel ladle. The castable consists of the following materials in percentage by weight: 20-25 percent of a high-aluminum clinker, 10-15 percent of bauxite cement, 8-10 percent of silica micro-powder, 20-40 percent of aluminum oxide and 10-20 percent of fused magnesite. The invention aims to provide the refractory castable which is ideal in performances, long in service life and low in cost, for the steel ladle.
Description
Technical field
The present invention relates to the technical field of metallurgical refractory materials, specifically a kind of ladle refractory castable.
Background technology
It is reported, test at present relatively successfully belongs to the Mgo-ZrO of Japan's exploitation
2matter mould material, it ladle slag line position damage speed be 1.25mm/ stove, although density is improved, cause its consumption and cost higher, make ton steel cost of resistance to material higher.In today of smelting technology development, subsequent treatment process after molten steel tapping becomes increasingly complex, the residence time of molten steel in ladle is more and more longer, this more aggravates the temperature drop of molten steel in ladle, smooth and easy in order to ensure pouring molten steel, must tapping temperature be improved, which results in the raising of smelting molten steel cost.Along with the raising of Refractory Carstables for Ladles density and the quickening of molten steel temperature drop speed, easily make molten steel and slag be bonded on steel ladle, cause ladle volume to diminish overweight with ladle, the direct motion that impact is produced.
Summary of the invention
The object of the invention is to be to provide a kind of performance desirable, long service life, the ladle refractory castable that cost is low.
The technical solution used in the present invention is, a kind of ladle refractory castable, and described each material is by following weight percent composition: high alumina 20-25%, luminite cement 10-15%, silicon powder 8-10%, aluminum oxide 20-40%, electrosmelted magnesite clinker 10-20%.
Advantage of the present invention to use mechanized construction, has good slag resistance, resistance to flaking, high life, the steel ladle casting material that cost is low.
Embodiment
The present invention is further described with the following Examples.
Embodiment 1, each material described in a kind of ladle refractory castable is by following weight percent composition: high alumina 20%, luminite cement 15%, silicon powder 8%, aluminum oxide 40%, electrosmelted magnesite clinker 10%.
Embodiment 2, each material described in a kind of ladle refractory castable is by following weight percent composition: high alumina 25%, luminite cement 10%, silicon powder 10%, aluminum oxide 20%, electrosmelted magnesite clinker 20%.
Embodiment 3, each material described in a kind of ladle refractory castable is by following weight percent composition: high alumina 22.5%, luminite cement 12.5%, silicon powder 9%, aluminum oxide 30%, electrosmelted magnesite clinker 15%.
Should be understood that this embodiment is only not used in for illustration of the present invention to limit the scope of the invention.In addition, should be understood that those skilled in the art can make various changes or modifications the present invention, and these equivalent form of values fall within the protection domain that the application's appended claims limits equally after having read the content that the present invention lectures.
