Description
Technical field
The present invention relates to enamel fields, more particularly to a kind of high-temperature enamel for high-chromium white cast iron.
Background technology
High-chromium white cast iron is a kind of heat-resistant and wear-resistant material of function admirable, wherein Cr2O3Content is 11.3-30%, is used
720-950 DEG C of temperature is widely used high-temperature and wear-proof in modern industry.It is modern with the demand for development of industrial technology
The temperature of sintering furnace be increased to 1050-1200 DEG C it is even higher.It has been more than the working limit of 950 DEG C of high-chromium white cast iron,
Occur in the quickening of oxidation corrosion rate, lost of life problem, especially furnace gas in the case of sulfur-bearing, high temperature corrosion is tighter
Weight.To solve the above problems, being often used fireproof coating, it is coated on the surface of high-chromium white cast iron, it is anti-oxidant in the hope of reaching a high temperature
Purpose, but coating is loosely easily peeled off with substrate bonding, and pin hole and bubble easily occurs in the enamel on high-chromium white cast iron,
Enamel does not have protective effect to base material.
Therefore, in view of the above-mentioned problems, the present invention provides a kind of high-temperature enamel for high-chromium white cast iron, height is solved
Antioxidant wear-resistant in chromium white cast iron hot operation damages problem, and is combined well with enamel, and pin hole and bubble are avoided
Occur.

The problem of, make high-temperature enamel that there is excellent high temperature corrosion-resisting antioxygenic property, enamel is Nian Jie with high-chromium white cast iron secured,
Generation without stripping and oxidative phenomena.
To achieve the above object, the present invention provides following schemes：
The present invention provides a kind of high-temperature enamel for high-chromium white cast iron, it is characterised in that：The high-temperature enamel is by weight
Amount percentage contains following component：Al2O315-35%, SiO211.5-45%, ZrO23-16%, CoO 1-4%, TiO2
2.5-13.5%, Cr2O31.5-7.9%, Fe2O30.5-12%, CaO 3-6%, Li2O 1-15%, K2O 3-8%, MgO
2.5-9.3%, P2O53-18%.
Preferably, the high-temperature enamel for high-chromium white cast iron is made of by mass percentage following raw material：Al2O3
9.3-21.3%, feldspar 20-31%, quartzy 4-7%, ZrO23-16%, CoO 1-4%, TiO22.0-10.5%, Cr2O3
1.5-7.9%, Fe2O30.5-12%, dolomite 5-15%, Suzhou soil 3-10%, LiCO32.5-37%, Al (H2PO4)3 5-
25%, cordierite crystallite porcelain 3.5-30%.
Preferably, the Al2O3And ZrO2Diameter of particle be 0.06mm, wherein 50-200 μm containing 15-40% super
Micro powder granule.
Preferably, the cordierite crystallite porcelain is made of by mass percentage following raw material：SiO248-53%, Al2O3
21-25%, MgO 15-18%, TiO29.5-11.5%, P2O50.5-5%.
Preferably, the Al (H2PO4)3It is formulated as：Add water to stir evenly a concentration of 85% industrial phosphoric acid to be configured to
Then Al (OH) is added in a concentration of 60% aqueous solution3, it is heated to 70-80 DEG C, reacts 30-60min, until after solution is clear,
Generate Al (H2PO4)3；
The cordierite crystallite porcelain is prepared as：With the composition of raw materials described in balance precise claim 4, mixing
It is placed in the high temperature furnace of oxidizing atmosphere and 1600 DEG C of meltings is warming up to 6-8 DEG C/min, keep the temperature 3-6h, it is natural fully after dissolving
1240 DEG C are cooled to, 8h is kept the temperature, Crystallizing treatment is carried out, is cooled to room temperature, generates cordierite crystallite porcelain.
Preferably, the Al (H2PO4)3Preparation in, the Al (OH)3Weight ratio with phosphate aqueous solution is 1:6.7.
By the study found that grey cast-iron is the reason of can well be combined with enamel：C in grey cast-iron has penetrated into
And be present in ferrite, so section gray, the C in grey cast-iron tissue can act on forming Si-C with the Si in enamel
Key, to the combination of advantageous enamel and cast iron.And because thering is other composition of alloy, C to penetrate into ferrite seldom in white cast-iron, and
It is most of to be present in the form of carbide in iron tissue, so section is silvery white in color.Carbide in high-chromium white cast iron exists
950-1050 DEG C is easily decomposed, and CO and CO is released2Gas breaks through enamel coating, causes the bubble and pin hole of porcelain facing.And the sulphur in cast iron
It is a kind of harmful substance, is not only dissolved in cementite, hinders the graphitizing process of carbon, also easily deposited in Cast Iron Surface and sulphur is precipitated
Compound makes Cast Iron Surface generate small breach and aperture, bubble etc..
Therefore, the present invention by using high temperature and addition TiO2The C in high-chromium white cast iron tissue is eliminated to enamel
Destructiveness, if the de- C treatment temperatures of high-chromium white cast iron are 950-1050 DEG C, and the present invention enamel firing temperature be
1250-1300 DEG C, the C before enamel coating does not melt in high-chromium white cast iron tissue is most of from the gap of glaze layer raw water point
Removing, and the remaining C and TiO in material2Effect can form the TiC being not easily decomposed, to eliminate C pairs in high-chromium white cast iron
The destruction of enamel.
And the blackening enamel on grey cast-iron, it is necessary to first keep the temperature 30-60 minutes at 750 DEG C or more and carry out de- C processing, then
Application of slip enamel, and high-chromium white cast iron is due to there is other composition of alloy, and S, P, C content are higher in organizing, the enamel applied
Easily there is pin hole, bubble.So applying the de- C techniques before glaze present invention eliminates cast iron, and avoids institute's glass-lined and easily occur
The generation of phenomena such as pin hole, bubble.
The present invention is by being added Al (H2PO4)3The pearlite (P) in high-chromium white cast iron is set to decompose, P is white in high chromium
It is to be the eutectic that P is combined with other elements existing for bianry alloy, ternary alloy three-partalloy or multicomponent alloy in mouth cast iron, P exists
950-1050 DEG C can promote high-chromium white cast iron surface to generate the combination of dissolving each other that liquid phase increases enamel and base material.
The present invention makes porcelain facing form microstructure, enhances enamel coating after being burnt by the way that cordierite crystallite porcelain is added
Intensity, hardness and cold and hot shock property.
The present invention is used for the high-temperature enamel of high-chromium white cast iron, and base material does not have to surface treatment, can directly apply glaze, simplify
The technique of surface treatment, and the high-temperature enamel for high-chromium white cast iron of the present invention only needs the application of slip one for bottomless glaze ceramic material
It is secondary.
The present invention be used for high-chromium white cast iron high-temperature enamel, directly by raw material add water grind formed dispersion liquid prepare and
At simplifying from raw material-and-cumbersome technique of water quenching-defibrination be melted, can save energy 60% or more.
The present invention is used for the high-temperature enamel of high-chromium white cast iron during being sintered with base material, Al (H2PO4)3Heated
It is polymerize in the process and is decomposed, decomposition product can be with the SiO in high-temperature enamel2、Al2O3It reacts, meanwhile, pate dure
P elements, aluminium element in glaze diffuse into base material, interfacial reaction can occur with substrate surface oxidation film, form connection knot
The transition zone of structure plays good connection function.
