Description
Technical field
The invention discloses a kind of preparation methods for coating far infrared glaze layer stuffing sand, belong to refractory material technology of preparing neck
Domain.
Background technique
A kind of bias furnace tapping essential refractory material, i.e. stuffing sand, it is mainly with Henan forsterite, Liaoning
The fused magnesite of Dashiqiao is primary raw material, and Yichang carbon materials are additive, by specific partial size and weight percent
It is combined, is mixed and be prepared into stuffing sand, proved after on probation, which has good dispersion flows, fire resisting
Degree is high, is not sintered, do not block, tapping rate drainage rate is up to 100%, using temperature >=1750 DEG C, does not occur with molten steel and alloying component
Chemical reaction, store quality do not occur changeability, are able to satisfy process for making requirement, are that eccentric furnace makes steel optimal fire proofed wood
Material.
It requires to be sintered at a lower temperature using stuffing sand, causes thing to avoid stuffing sand floating when molten steel is added
Therefore；It is required that meeting molten steel face under high temperature and long-time smelting state cannot be sintered too thick, in the hope of reaching automatic casting, production is improved
Efficiency reduces molten steel pollution, reduces flue gas consumption, improves production safety coefficient.
If refining ladle is unable to automatic casting when pouring steel, understands some molten steel and opens wide casting, secondary oxidation occurs,
Field trash is brought into crystallizer simultaneously, makes that casting billet surface is cracked, the defects of being mingled with, reduces the quality of slab, this is right
The production of high standard variety steel is particularly disadvantageous.
In the prior art, stuffing sand usually has following four classes: chromium matter stuffing sand, using ferrochrome sand, quartz sand as main material, adds
Carbonaceous binder mixing drying is added to be made.The casting rate of chromium matter stuffing sand is high, and still, contained chromium oxide can produce molten steel and environment
Raw pollution, SiO2 also pollute molten steel.Forsterite is mixed drying with raw materials such as additives by white olivine stuffing sand
It is made.White olivine stuffing sand it is cheap, but continuous casting automatic casting ratio is low, and silicon in stuffing sand and magnesium may also
Molten steel is polluted, is especially not suitable for limiting stringenter high-grade steel smelting to silicon, magnesium.Siliceous stuffing sand, by sea sand or stone
Sand, potassium feldspar and additive mixing drying are made.Although the fusing point of silica sand is 1680~1700 DEG C, siliceous stuffing sand exists
1200 DEG C can undergo phase transition, and thus cause biggish volume expansion, cause the adhesive force of back-up sand and mouth of a river inner wall to increase, serious shadow
The mobility for ringing stuffing sand, is unfavorable for opening the free-falling of stuffing sand when pouring.Siliceous stuffing sand is although cheap, but opens and pour
Rate is lower, and silicone content is too high, can generate pollution to molten steel, be not suitable for the needs of high-grade refining steel grade.Zirconium matter stuffing sand, with
Zircon is primary raw material, and a small amount of carbon dust mixing is added and dries.The content of zirconium silicate is resistance to not less than 97% in zircon
Fiery degree is higher than 1800 DEG C, and zircon, which has, corrodes the excellent performances such as penetrating power is strong and stability is strong than great, anti-molten steel, is
The desirable feedstock of ladle draining sand is done, but it is expensive, it does not use substantially in the actual production process.
With the development of world economy and the progress of science and technology, social every field proposes the quality of steel higher
Requirement." fine work steel theory " deepens constantly in iron and steel enterprise, and domestic large size steel mill is while improving iron and steel output, more
Focus on the production of high standard variety steel.The development of continuous casting and external refining is so that production efficiency is improved, but taps simultaneously
Temperature becomes higher, and molten steel biography, which puts the time, becomes longer, and traditional stopper system has been difficult to meet the requirements, instead then
It is ladle nozzle system.
Therefore, it is high and will not influence the stuffing sand of casting rate and be to technical field of fire-resistant material preparation to invent a kind of refractoriness
It is necessary to.
Summary of the invention
Present invention mainly solves the technical issues of, for the development of current continuous casting and external refining so that production efficiency obtains
It improves, but simultaneously tapping temperature becomes higher, molten steel biography, which puts the time, becomes longer, and such as under this condition, molten steel is easy to produce cold
Solidifying steel, expansion rate is higher at high temperature with chromium matter stuffing sand for commonly siliceous, seriously affects casting rate, while stuffing sand refractoriness
