The present invention also provides the preparation method of the enhanced base steel material of alumina composite ceramic described above, its technical scheme
It is：
First, the raw material of the steel configured in mass ratio is added into smelting furnace, is heated to 500 DEG C~700 DEG C；Then, will be mixed
The powder for closing the composite ceramics of drying adds smelting furnace；Treat that ceramic powders and molten steel are completely melt, you can casting tapping.Ceramic powder
The temperature that end and molten steel are completely melt is 1600 DEG C~1700 DEG C, general desirable 1650 DEG C.
The composite ceramics base steel material is smelted using intermediate frequency furnace.
The preparation technology of the composite ceramics is：
Example is configured to ceramic material in mass ratio, after the ceramic material configured is mixed 1~6 hour, drying, forms described
The powder of composite ceramics.
The raw material of steel is steel scrap in the base steel material.
It is of the invention main using aluminosilicate raw ore stone flour materials such as domestic non-metal stupaliths, and waste metal material,
Melting is heated in middle frequency furnace, makes material in different temperatures stage chemical combination decomposition and crystallization.
In the range of 1650 DEG C of the effective temperature of middle frequency furnace, by ceramic material by melting decomposition and crystallization, decomposing again, again
The process of three decomposition and crystallizations of crystallization, forms ceramic dispersoid composite construction reinforced transformation, generates new steel grade material --- member
Brilliant special steel (PH steel).First crystalline substance special steel (PH steel) has also has higher toughness, height simultaneously while high intensity, high rigidity is ensured
Wearability, high-fire resistance energy, preferable corrosion resistance.
The process analysis of above-mentioned preparation method：
In melting ceramic material, part nonmetallic materials start to slowly escape through in temperature in 300 DEG C~800 DEG C stages
Liquid, overflows liquid and starts nodularization ceramic powders, forms the small block and sphere shape differed in size.The liquid of spilling has simultaneously
Catalytic metal material property, makes it obtain synchronous nodularization, thawing, decomposition with ceramic material, reaches extensive crystallization for the first time.
It is because the proportion difference of ceramic material and metal material, ceramic material produces suspension and effectively controlled just to put type crystallization purpose
System.This stage definitions crystallizes just to put type.
As temperature rises to 900 DEG C~1350 DEG C stages, primary crystallization is decomposed again, but without complete knot
It is brilliant.Liquid is mutually very thin, and impurity is assembled with the motion of molten steel to furnace wall in original ore powder material nonmetallic ceramics.Furnace wall it is solidifying
Compound is slowly decomposed with liquid steel temperature and molten steel motion.Solidifying compound also has the melting at high temperature of protection stove inner wall simultaneously
Infringement.The stage effectively can not decompose completely.This stage definitions decomposes the impurity phase for second.
As temperature rises to 1500 DEG C~1650 DEG C stages, the rising of liquid steel temperature and molten steel motion accelerate, also slowly
There is fine crystal state；When reaching 1650 DEG C of rated temperatures, microcrystalline state fast decoupled within a very short time.Decomposite
A small amount of impurity is formed in molten steel surface, and molten steel is very limpid, bright after cleaning impurity, thoroughly decomposes complete liquid body.During this
It is referred to as phase transformation decomposition and crystallization end period, forms the stable crystalline body of complete disperse composite construction reinforced transformation, referred to as
The decomposition and crystallization of three times.
The crystalline solid has unique performance, the advantages of metal material high rigidity, high intensity and ceramic material it is high resistance to
Mill and the anti-corrosion intensity and hardness for waiting excellent properties organically to combine, making the holding of its product high-temperature area higher, are not likely to produce tired
Labor crackle；There is resistance to corrosion to chemical substances such as common acid, alkali, salt simultaneously.Therefore with very strong adhesion, very high
Hardness and preferable stability at elevated temperature, have higher abrasion resistance, low coefficient of friction again.Here it is above-described member is brilliant
The performance that special steel (PH steel) possesses.
The enhanced base steel material of the alumina composite ceramic, can be as cast condition, forging state, rolled.With steel scrap and honest and clean
The ceramics of valency mineral prepare composite ceramics base steel material, the preparation method of this material be made of Medium frequency induction melting casting or
Ingot casting；Ingot casting can pass through forging or roll forming.The mechanical performance of this material can reach：
Yield strength 450MPa~900MPa, tensile strength 750MPa~1500MPa, the contraction percentage of area 15%~25%,
Elongation percentage 25%~35%；The hardness of material is 25HRC~65HRC；Ballistic work is 50J~150J.
Also there is following performance：
Fatigue crack is not likely to produce under temperature province state uneven in temperature；Corrosion resisting property：Mill amount loss reduce 5 times with
On；7 days non-corrodings are soaked in 5% hydrochloric acid；At 800 DEG C, its hardness number reaches highest, therefore, with excellent elevated temperature strength
With high temperature red hardness；The coefficient of expansion is low；Service life is more than 3~5 times of heat-resisting alloy steel of the prior art；Metallographic structure
Uniformly, it is fine and smooth, material property appearance and internally consistent.
Above-mentioned data and performance show that base steel material of the invention is a kind of high abrasion, anti-corrosion composite.Meanwhile,
With domestic general high-abrasive material ratio, it is practically free of, the precious metal such as tungsten, molybdenum, manganese, nickel, vanadium, copper, cobalt, is a kind of resources conservation
The high strength wear resistant material of type.
Above-mentioned composite ceramics base steel material, its element constitutive material by commercially available, be made through smelting casting technique,
Forging technology or rolling mill practice are known prior arts.Involved metallurgical equipment and technique is those skilled in the art institute
It is known.Therefore, the cost of technical scheme is lower than prior art.
