Abstract
The invention relates to a special-purpose coating material for steel slag removing harrows, which mainly 50-60% of soil form graphite, 20-30% of lamellar graphite, 10-20% of coke powder, 10-20% of calcium carbonate powder, and water 30-60% of the total amount of the constituents.
Description
Technical field
The present invention relates to a kind of coating, specifically, is a kind of special coating for slag harrow.Described slag rake is to be used for the Cinder Machine that the slag of molten steel or ladle is removed or the corollary apparatus of dragveyer.
Background technology
The slag rake of steel (iron) water Cinder Machine or dragveyer need often dip in and get or brush coating when work.Its effect mainly contains two, and the first is implemented to apply protection to the slag rake, avoids high-temperature steel (iron) water logging erosion; It two is to prevent that scum from directly adhering to slag rake metal surface and be difficult for removing.
Existing special coating for slag harrow main component is a graphite, such as amorphous graphite or crystalline flake graphite.Facts have proved that there is following major defect in existing coating: promptly scum and dope layer are bonding too closely, firm, adopt usual way to be difficult to slag is harrowed the scum removal on surface, need manually strike off.Not only increase the amount of labour, reduced production efficiency, and have certain potential safety hazard.On the other hand, band slag work in slag rake surface has influenced normally carrying out of scarfing cinder work again.
Summary of the invention
Technical problem to be solved by this invention provides a kind of new special coating for slag harrow for removing slag of iron and steel, and slag rake dips in to get or brush and combines behind this coating loosely with scum, is easy to scum is bled off.
In order to address the above problem, the present invention has adopted following technical scheme.
A kind of special coating for slag harrow for removing slag of iron and steel, its special feature is: it mainly comprises the amorphous graphite of 50-60%, the crystalline flake graphite of 20-30%, the coke powder of 10-20%, the Paris white of 10-15%, said components is made 200-1000 purpose powder respectively, and makes with the water mixing and stirring of said components total amount 30-60%.
Optimized technical scheme is: it is by the amorphous graphite of 50-60%, the crystalline flake graphite of 20-30%, and the coke powder of 10-20%, the phosphoric acid calcium powder of 10-15% is formed; Above-mentioned each component is made 200-1000 order pulvis respectively; Then with the adhesive of said components total amount 3-8%, the suspending agent of 3-8%, the water mixing and stirring of 30-60% is made.
Described adhesive is a white glue with vinyl, and suspending agent is a bentonite.
The various components among the present invention and the selection of consumption thereof all are key technologies, the too high or too low all inaccessible technique effect of the present invention of each amounts of components value.
Wherein coke powder and Paris white have certain refractoriness, simultaneously can in high temperature liquid iron, produce a certain amount of gas, make coating have foaming effect, finished product coating forms porous material, effectively prevent the strong bond of coating and molten iron, gently knocking the slag rake can bleed off scum at an easy rate from the removing of slag rake.
