Description
Technical field
The invention belongs to technical field of refractory materials, and in particular to a kind of calcareous slag adhesion spray paint for converter mouth.
Background technique
The equipment of steel plant's pneumatic steelmaking usually will appear serious dry slag phenomenon, the dry slag of converter mouth in use
Become it is changeable it is thick after will affect the size of converter mouth, when fire door reduces, the speed of molten iron plus steel scrap is reduced, while can also make
Oxygen rifle downlink.Since dry slag is Nian Jie with the refractory material in equipment securely, thus scarfing cinder is very difficult, and average scarfing cinder once needs
30~40min, the slag hitting time is long, delays steel-making.Current each steel mill is that the measure that mitigation dry slag is taken is varied, usually
Converter mouth is sprayed using spray paint, spray paint is wrapped in converter mouth, utilizes the substance and converter liquid slag in spray paint
And the centrifugation of remaining molten steel makes to make steel dry slag not hang and is attached to converter mouth, to realize slag adhesion effect.
Main raw material(s) the prior art mainly adopts bauxite as slag adhesion spray paint, higher cost, and aluminium alum
Soil reaction is slower, general so as to cause slag adhesion effect.Chinese patent CN1429677A, which discloses one kind, prevents steelmaking container
The oxidation calcium paint of dry slag, the coating is by lime stone, calcium hydroxide, SiO2Micro mist, sodium tripolyphosphate, waterglass and paper fiber etc. are former
Material is prepared, which has many advantages, such as that resistance to slag is good, high temperature resistant, but lime stone and calcium hydroxide combine in the program, can make
The spray paint cohesion that must be prepared is fast, it is necessary in a short time be finished the slurry stirred, otherwise be easy blocking spraying gun barrel.And
And contain sodium tripolyphosphate in raw material, which thermal decomposition can occur at high temperature and generate irritative gas and toxic gas (such as
The oxide of phosphorous oxides and sodium), there is some potential safety problems.
Summary of the invention
The slag hitting time is long when to solve to handle converter mouth dry slag in the prior art, the cohesion of slag adhesion spray paint is fast, slag adhesion
The bad disadvantage of effect, the purpose of the present invention is to provide a kind of calcareous slag adhesion spray paints for converter mouth.
For achieving the above object, the technical solution adopted by the present invention are as follows:
A kind of calcareous slag adhesion spray paint for converter mouth, adds water to be prepared: carbonic acid by the raw material of following weight percent
Calcium powder 85~90%, metal zirconium powder 2~5%, carborundum powder 2~5%, dispersing agent 1~3%, thickener 2~4%；
The thickener is mixed by starch and xanthan rubber powder by the weight ratio of 1~2:1~2；
The quality of the water is the 30~40% of above-mentioned raw materials gross weight.
Further, water is added to be prepared by the raw material of following weight percent: Paris white 88%, metal zirconium powder 3%,
Carborundum powder 4%, dispersing agent 2%, thickener 3%；
The thickener is mixed by starch and xanthan rubber powder by the weight ratio of 1:1；
The quality of the water is the 35% of above-mentioned raw materials gross weight.
Further, the fineness of the Paris white is 400~600 mesh, CaCO in Paris white3Content >=95%.
Further, the fineness of the metal zirconium powder is 180~260 mesh, Zr content >=65% in metal zirconium powder.
Further, the fineness of the carborundum powder is 180~300 mesh, SiC content >=92% in carborundum powder.
Further, the dispersing agent is one of carbon black, graphite and petroleum coke powder or a variety of, and the fineness of dispersing agent is
180~300 mesh.
Further, the fineness of the starch is 180~280 mesh, and the fineness of the xanthan rubber powder is 200~260 mesh.
Above-mentioned calcareous slag adhesion spray paint the preparation method comprises the following steps: a, above-mentioned raw materials are weighed in proportion；B, it adds raw materials into
It is stirred evenly to stirrer for mixing, c plus water are mixed.
In use, take above-mentioned calcareous slag adhesion spray paint, it is painted on converter mouth position, each spray time 1~
3min, with a thickness of 1~3mm, preceding primary for fixed 3 furnace steel of every refining spraying twice, third time can normally make steel 6~10 furnaces after spraying
Spraying is primary, can make steel immediately after spraying every time.
Compared with prior art, the invention has the following advantages:
The present invention is using Paris white as primary raw material, and carbon black, graphite and petroleum coke powder are as dispersing agent, calcium and dispersing agent knot
It closes, plays the role of separating spray paint with fire door dry slag jointly, so that dry slag is not easy to hang over converter mouth；Starch and xanthan gum
Powder is thickener, is not easy to precipitate in 6 hours, prevents blocking lance tube；Metal zirconium powder and the high temperature resistant of carborundum powder itself are steady
It is qualitative to play the role of anti-erosion, antiscour, anti-oxidant, resistant to high temperature in the present invention, prevent spray paint from producing at high temperature
Change shape, sagging phenomenon.Calcareous slag adhesion spraying material formula of the invention is simple, preparation is convenient, and the spray of 3 furnace steel of every refining is primary, often
Secondary spray time is 1~3min, with a thickness of 1~3mm, can adhere to that the spray of 6~10 furnaces is primary after continuous spray twice, slag adhesion effect
Good, slag hitting only needs 8~12min, saves the slag hitting time, increases the steel-making time, has high economic benefit.
