Background technique
It is easy to produce ferriferous oxide on hot rolling technology light plate surface, especially contains nickel steel, Ni is enriched with shape in oxide layer
At the metal twine and particle of Ni, with continuing for heating process, the metal twine of this Ni layers of richness is by metallic matrix and oxidation
Layer connects together, and oxide layer is caused to have very strong adhesive force in billet surface, and thickness is deep, area is big.Due to the gold
Belong to twine-oxide layer structure plasticity and thermal expansion coefficient is close with metallic matrix, therefore only leans on height to remove the oxide layer
Warm water pressure be it is far from being enough, the later period still needs to expend and greatly manually carries out repairing film or pickling to steel billet, and often effect is not
It is good, and the lumber recovery decline of steel, it pollutes the environment.The whole nation every year because caused by high temperature oxidation and corrosion output of steel loss reach
3% or more.
The oxidation layer method is substantially following several for capable of removing of using at this stage, and passes through the heating system of optimization steel billet
Spend, change the atmosphere in heating furnace and then steel billet is protected, improves de-scaling hydraulic pressure etc., but all multi-methods all have little effect,
The generation and/or person that cannot fundamentally reduce oxide layer reduce the adhesive force of oxide layer and steel billet.
Summary of the invention
Goal of the invention: the first object of the present invention is to provide a kind of generation that can fundamentally reduce nickeliferous steel oxidation layer
And oxide layer and steel billet adhesive force are reduced, make it easy to the high-temperature oxidation resistant de-scaling interleaving agent removed；
The second object of the present invention is to provide the preparation method of above-mentioned de-scaling interleaving agent.
Technical solution: the present invention is based on the high-temperature oxidation resistant de-scaling interleaving agents containing nickel steel, which includes quality
Than for 6~10:1~3:0~2:0.05~0.8 composite inorganic powder, inorganic binder, water and suspending agent；Wherein, described multiple
It includes: nitride 20~36%, silicon powder 15~30%, silicon carbide 5~25%, powder containing ferrochrome that inorganic powder, which is closed, by mass fraction
15~38%, aluminium oxide 8~15%, magnesia 1~14%, calcium oxide 1~6% and boric acid 2~8%.
High-temperature oxidation resistant de-scaling interleaving agent of the invention by by nitride, silicon powder, silicon carbide, powder containing ferrochrome, oxidation
Aluminium, magnesia, calcium oxide and boric acid compounding, on this basis in conjunction with inorganic binder, water and suspending agent, and then the height prepared
The anti-oxidant de-scaling interleaving agent of temperature can fundamentally reduce generation and the drop of nickeliferous steel oxidation layer at high temperature (900~1300 DEG C)
The adhesive force of suboxides layer and steel billet is allowed to be stripped clean under the simple measures such as giant, reduces subsequent de-scaling
Process and artificial investment.Preferably, it is that 6~10:1~2.6:0~2:0.06~0.8 is compound that de-scaling interleaving agent, which includes mass ratio,

Micro mist 15~30%, silicon carbide 5~21%, powder containing ferrochrome 15~28%, aluminium oxide 8~12%, magnesia 5~10%, oxidation
Calcium 2~6% and boric acid 1~5%.
Since steel billet is slower in 1000 DEG C of oxidations rate below, but works as temperature and reach 1100~1200 DEG C or more, oxidation
Rate doubles, therefore coating needs to have good anti-oxidation bridging effect to steel billet at 1000 DEG C of high temperature or more, especially exists
1200 DEG C or more.After the interleaving agent is coated on steel billet, heating is initial, and the boric acid dehydration of low melting point generates B2O3, with steel
The micro oxide skin in surface forms sticky iron borate melt film, and is acted synergistically by inorganic binder and other inorganic powders,
Making coating tentatively has anti-oxidation effect；With the rising of temperature, inorganic binder in system, a large amount of Si member contained in powder
Element, reaction generates Fe under the action of the oxides such as silica and oxygen2SiO4It is interspersed in system glassy state melt film, hinders iron
Diffusion of the ion in iron scale has completely cut off erosion of the partial oxidation to matrix to a certain extent；When temperature rises to 1000~
1100 DEG C, the SiC in system is gradually consumed oxidation and generates SiO2, the reaction preferentially consume the oxygen near matrix for matrix battalion
Make reducing atmosphere, and at this time coating by step by step heating and oxidation reaction form based on Ca-Mg-Al-B-Si-O
Fine and close Glassy polymer structure, effectively oxygen can be prevented to enter matrix；And continue to increase with temperature, SiC is gradually
It is depleted, at this time Si in coating3N4It is the main component that (> 1200 DEG C) coating plays the shielding action of inertia melt film under high temperature, at this time
Si3N4Passive oxidation occurs and firstly generates amorphous glass state SiO2, with SiO remaining in coating2Crystallization occurs and generates crystalline state
SiO2, the viscosity of coating is further increased, billet surface is made to form what one layer of fine and close crystal phase was mixed with glass at high temperature
Protective film prevents contact of the interior nickel steel matrix with oxidizing gas；Also, Si3N4It, can be aptitudinal during oxidation
In surface SiO2The inside of protective film generates one layer of Si2N2The nitrogen oxygen layer of O, can be further improved the consistency of protective coating, greatly
Oxidation rate is reduced greatly.
Therefore at high temperature, even if the Ni element in nickeliferous steel matrix has been progressively enriched in steel surface and oxide skin
Come, as around Ni anoxic and the wire mesh of Ni-O cannot be formed, reduce the adhesive force of oxide skin and matrix, cause oxygen
Change skin and is easy to same protective film together from base's peeling in the later period；Secondly, the Cr in protective film reacts at high temperature with the Ni of enrichment
Generate NiCr2O4Spinel structure, Cr consumes the Ni in this Ni layers of richness, also weakens oxide layer and nickel steel matrix indirectly
Adhesive force, be easy to remove together with oxide film in the later period.
In addition, calcium oxide softening point is lower, its addition can not only reduce sintering temperature, promote magnesia, aluminium oxide
The melting of equal infusibilities substance forms glass phase, reduces coating viscosity, increases the adhesive force of coating and matrix, while cooperateing with Mg, Al
The spinel structure for forming Mg-Al-Fe at high temperature with Fe more preferably resists the further oxidation of matrix.Under high temperature, Cr's is de-
Oxygen ability is stronger compared with Si, is added under the high temperature of powder containing Cr and forms FeCr between iron scale and matrix steel2O4, effect with
Fe2SiO4It is identical.
Furtherly, inorganic binder can be inorganic silica solution, Aluminum sol, aqueous silicate solution or phosphate aqueous solution,
Preferably, inorganic binder can be inorganic silica solution.Suspending agent can include at least modified alta-mud, meteorological white carbon black, polypropylene
One of amide, methylcellulose, polyvinyl alcohol, it is preferred that suspending agent can be modified alta-mud and/or methylcellulose.
