Abstract
The invention discloses a high-temperature-resistant composite ceramic which is characterized by comprising the following components in parts by weight: 35-60 parts of mullite, 15-41 parts of alumina, 10-30 parts of tin power, 10-40 parts of sandstone, 3.5-10.5 parts of boron carbide, 0.5-3 parts of copper oxide, 1-5 parts of white alkali, 5.8-13.7 parts of magnesium oxide, 1-8 parts of calcite, 10-20 parts of wollastonite, 5-17 parts of acetylacetone hafnium, 35-46 parts of iron ore, 30-50 parts of trichloromethane, 3.5-10 parts of barium carbonate and 40-80 parts of diamond. The high-temperature-resistant composite ceramic is reasonable in formula. The preparation technique is simple to operate, and lowers the formation temperature and required pressure of the blank. The prepared composite ceramic has greatly higher toughness, wear resistance and corrosion resistance.
Description
Technical field
The present invention relates to a kind of high temperature resistant composite ceramics.
Background technology
At metallurgy industry, along with the fast development of Iron And Steel Industry, equipment operation vibration amplitude also increases, and has aggravated the unstable of pipeline.If the pipeline working temperatures such as sinter machine large flue, cleaning shaft, raw coke oven gas pipeline, bellows pipe, ash dropping hopper, feed bin, fly-ash separator inner casing, tank bit platform are at 350-850 ℃, to bear for a long time the above wind speed of 10-15 m/s jointly washing away together with breeze, particle flue dust, and the erosion of the acidic medium such as water vapour, S, P, N and C, the phenomenon that causes pipeline to shorten work-ing life is more and more outstanding.
In power industry, characteristic due to power station, as the positions such as the coal pulverizer pipeline of station boiler, feed bin, hopper, thick, pulverized-coal collector, primary air inlet, induced draft fan, mill exhauster inner casing, fan blade, furnace roof flue corner, furnace outlet, cyclonic separator, material returning device wind slag pipe, economizer plate and station boiler other easily wash away, abrading section, at equipment, to be subject to the wearing and tearing of the Solid Bed material of fuel, fuel ash, Wingdale and reaction product thereof every day in service.Refractory materials, with the lifting of temperature, produces and expands or shrink, if this expansion or contraction suffer restraints, material internal can produce stress.Refractory materials is heterogeneous hard brittle material, compare with metal products, due to it thermal conductivity and elasticity is less, tensile strength is low, opposing thermal stress damage ability, heat-shock resistance are lower, under heat shock cycling effect, refractory materials easily first occurs that cracking peels off eventually to be damaged to whole.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of high temperature resistant composite ceramics.
For solving the problems of the technologies described above, the technical solution used in the present invention is:
A high temperature resistant composite ceramics, is characterized in that, comprises the material of following parts by weight: mullite 35-60 part, alumina 15-41 part, glass putty 10-30 part, sandstone 10-40 part, norbide 3.5-10.5 part, cupric oxide 0.5-3 part, white alkali 1-5 part, magnesium oxide 5.8-13.7 part, calcite 1-8 part, wollastonite 10-20 part, methyl ethyl diketone hafnium 5-17 part, iron ore 35-46 part, trichloromethane 30-50 part, barium carbonate 3.5-10 part, diamond 40-80 part.
The invention has the beneficial effects as follows: rationally, preparation technology is simple to operation for formula, reduces temperature and the required pressure of idiosome moulding, and composite ceramics toughness, wear resistance and the etch resistant properties prepared improve greatly.
