Technical field
The present invention relates to ferrous metallurgy technical field of refractory materials, refer to a kind of iron ladle slag adhesion coating particularly.
Background technology
In iron and steel metallurgical industry, iron ladle is blast-melted collection, the inner visual plant converting iron of transport and steel mill, and life cycle is longer.But in use, iron ladle slag line and tank very easily form the slagging scorification of slag iron along position, and progressive additive, have a strong impact on production efficiency and the production safety of iron and steel enterprise, must scarfing cinder process be carried out.But scarfing cinder process is damaged serious to slag line and tank along position refractory materials, not only have impact on iron ladle and normally have enough to meet the need, also reduce its work-ing life.Therefore, need to carry out slag adhesion process to iron ladle slag line and tank along position, reduce this position slag iron slagging scorification, reduce and check number of times.
Part steel mill iron ladle is more, has enough to meet the need unsaturated, has grace time to carry out cold conditions maintenance of rolling off the production line, and can, after cold conditions is safeguarded, adopt slag adhesion coating to carry out slag adhesion process.The advantages such as it is high that the method has utilization ratio, and consumption is few, but the cold conditions that rolls off the production line frequently is repaired, and is unfavorable for the turnover of iron ladle, also there is considerable influence to ladle lining whole service life.Therefore, need to develop a kind of slag adhesion excellent property, coking property good and there is the iron ladle slag adhesion coating of certain iron-resistant scouring performance, thus reach and reduce the slagging scorification of iron ladle slag iron, improve the object in iron ladle turnover life-span.
Summary of the invention
The object of the present invention is to provide that a kind of slag adhesion is functional, iron-resistant scouring excellent performance, sintering strength is high, cost is low iron ladle slag adhesion coating.
For achieving the above object, the technical solution used in the present invention is: a kind of iron ladle slag adhesion coating, and composition and the weight percent thereof of described coating are as follows: the fire-resistant useless brick A level material of carbon containing: 35-70wt%; Useless high alumina brick material: 10-35wt%; Black silicon carbide: 5-30wt%; Luminite cement: 3-8wt%; Guangxi white clay: 3-8wt%; Xylo-Mucine: 0.1-2wt%; Tripoly phosphate sodium STPP: 0.1-1wt%; Organic explosion-proof fiber: 0.1-1wt%; Unslaked lime: 0.01-1wt%; The fire-resistant useless brick A level material of described carbon containing obtains by the following method: aluminum-silicon carbide brick give up brick, the aluminium carbon of brick, magnalium carbon that gives up gives up the higher useless brick of utility value that brick obtains in selection, removal of impurities, removing metamorphic layer process, and drying, fragmentation, screening obtain the fire-resistant useless brick A level material of carbon containing that granularity meets scope.
Further, the composition of described coating and weight percent as follows: the fire-resistant useless brick A level material of carbon containing: 40-65wt%; Useless high alumina brick material: 10-35wt%; Black silicon carbide: 5-30wt%; Luminite cement: 3-8wt%; Guangxi white clay: 3-8wt%; Xylo-Mucine: 0.5-1.5wt%; Tripoly phosphate sodium STPP: 0.1-1wt%; Organic explosion-proof fiber: 0.1-0.5wt%; Unslaked lime: 0.01-1wt%.
Further, the composition of described coating and weight percent as follows: the fire-resistant useless brick A level material of carbon containing: 60wt%; Useless high alumina brick material: 17wt%; Black silicon carbide: 12wt%; Luminite cement: 5wt%; Guangxi white clay: 5wt%; Xylo-Mucine: 0.2wt%; Tripoly phosphate sodium STPP: 0.4wt%; Organic explosion-proof fiber: 0.2wt%; Unslaked lime: 0.2wt%.
Further, the granularity of the fire-resistant useless brick A level material of described carbon containing is: 0.088mm < granularity D < 3mm.
Further, the granularity of described useless high alumina brick material is: D≤0.088mm; Described useless high alumina brick material obtains by the following method: by Al
2o
3give up brick drying, deironing, fragmentation, fine grinding of the high alumina that content is not less than 48% obtains the useless high alumina brick material of granularity D≤0.088mm.
Further, the granularity of described black silicon carbide is: D≤1mm, and in described black silicon carbide, SiC content is not less than 90%.
Further, the described luminite cement trade mark is No. 625.
Further, in described unslaked lime, CaO content is not less than 80%.
In the present invention, the fire-resistant useless brick of carbon containing is after selection, removal of impurities, removing metamorphic layer, after the series of processes process such as the fire-resistant useless brick drying of the unreacted carbon containing obtained, deironing, fragmentation, screening, obtain the fire-resistant useless brick A level material of carbon containing, can directly use by Substitute For Partial raw material, its cost is low, and performance is good, and cost performance is high.
In the present invention, in the fire-resistant useless brick A level material of carbon containing, content of graphite is about 5% ~ 18%, and graphite has good slag corrosion resistance and slag penetration resistance, joins in this coating, effectively can reach the object of slag adhesion; But when content of graphite is too high, because of the oxidizable and not easy-sintering of graphite, cause Gunning refractory sintering strength low.Therefore in iron ladle slag adhesion resistant gunning refractory, add the fire-resistant useless brick A level material of carbon containing of reasonable amount, under the prerequisite not affecting sintering strength, effectively raise slag adhesion performance.
