Description
Technical field
The present invention relates to a kind of coating of anti-dross, be specifically related to a kind of metal-ceramic coating.
Background technology
Material sheet materials such as duplex stainless steel are a kind of high-end metal productss.The machine-shaping of material sheet materials such as metallurgy industry duplex stainless steel generally can be divided into thermo forming (hot rolling) and cold-formed (cold-drawn) two kinds of forms.
The Production Flow Chart of material sheet materials such as hot rolling processing duplex stainless steel is: material sheet material blanks such as (1) duplex stainless steel through roller at the bottom of stove be heated to 1100 ℃; (2) through hot rolling mill slab rolling is become to require the sheet material of specification; (3) through cutting edge, shearing, determine the size of customer requirement; (4) technology such as, pickling flat through thermal treatment, sedan-chair is delivered goods after the performance of material sheet materials such as duplex stainless steel is adjusted to customer requirement.
The hot rolled plate production line mainly comprises major equipments such as process furnace, hot rolls, shears, heat treatment furnace, the straight machine of sedan-chair, pickling line.
Hot rolled plate production line (blank-→ sheet material finished product) main technique route is following:
Blank warehouse-in-→ the blank shove charge, heat with come out of the stove-→ remove iron scale-→ blooming mill is rolling-→ Steckel mill is rolling-→ coil of strip batches and blanking-→ the thermal straightening machine aligning-→ steel plate cooling and surface inspection-→ steel plate shearing-→ check reconditioning and blanking-→ thermal treatment-→ pickling and ball blast.
The solid smelting furnace of thermal treatment is a material sheet material such as duplex stainless steel after rolling, carries out key equipments such as operation such as solution heat treatment.This solution heat treatment furnace adopts high temperature resistant furnace bottom roll in stove, to transmit sheet material; This heat treatment furnace is adjusted to processing requirement with plate property, gets into road, back manufacturing procedure.
The high temperature resistant furnace bottom roll of heat treatment furnace generally adopts corresponding structure and material according to different production processing requirements such as furnace, atmosphere.The solid smelting furnace of this thermal treatment adopts the naked light direct heating, and atmosphere is weak oxide property atmosphere, and furnace temperature is up to 1180 ℃.At present the solution heat treatment furnace furnace roller mainly is made up of parts such as, roller shell, packing gland, axle sleeve, the body of roll, welding block, thermal insulation material, axle bumpers roller.Wherein the body of roll is ZG40Cr28Ni48W5 (2848) superalloy material, adopts the moulding of centrifugal casting mode.
I.e. " dross " problem of speckle appears in the surface of the furnace roller body of roll under this high temperature, weak oxide property atmosphere.The major cause that produces " dross " phenomenon is because chemical reaction has taken place for element such as the Mn that contains in the steel band and furnace bottom roll surfacing, has generated the oxide compound that contains Mn.This oxide compound is in case after forming, be bonded at the furnace bottom roll surface, to steel band very easily cause pit, pull, defective such as cut, and general manual being difficult to of long-pending knurl remove, must adopt instruments such as file.The sheet material that " dross " very easily produces materials such as scuffing, particularly dual phase steel to surface of steel plate is under this temperature, and intensity is very little, and lower surface scratches serious, directly has influence on the quality of product, and this defective has had influence on the ordinary production of products such as dual phase steel.
Influencing the hidden danger of steel band quality in order to eliminate the long-pending knurl of roll surface. a lot of producers have adopted hot-spraying techniques.The coating that the furnace roller coating technology is exactly the method that adopts thermospray is low in the avidity of furnace roller surface spraying one deck and iron, its thermal expansivity and furnace roller body material are complementary, go back high temperature wear resistant.This coating can prevent that the furnace roller surface from producing long-pending knurl, thereby can obtain the good steel plate of surface quality.
These coatings should have following properties:
A, resistive connection knurl performance
The steel plate that continuous operation is arranged on the high-temperature furnace roller in stove.Because the restriction of the working of a furnace and related process parameter must form long-pending knurl on the furnace roller surface.In case furnace roller surface-area knurl situation is serious, certainly will form defective at surface of steel plate, directly influences plate quality.One of purpose of spraying high temperature coating is exactly to improve resistive connection knurl performance.
B, high temperature wear resistant performance
Furnace roller moves under the condition of high temperature, and its surface must keep suitable hardness, suitable roughness and very strong wear resistance according to processing requirement.
C, high temperature oxidation resisting
Furnace roller is owing to expose in stove for a long time, though gas shield is arranged, the possibility that oxidation appears in coating is still bigger, and surfaceness also can change thereupon, and is very unfavorable to producing high-quality steel plate.Therefore the spraying coating process of high-temperature furnace roller and the material important that just seems.
In addition, as thermospray, the lowest term that requires coatingsurface to reach is:
(1) coating and furnace roller base material must have high-bond and thermal shock resistance.
(2) coating has very strong cold-resistant thermal fatigue property.
(3) coating and matrix have close thermal expansivity.
What traditional furnace roller coating was used is that the coated component system is CoCrAlY-CrB
2/ Y
2O
3, spraying method is supersonic speed or plasma, because these two kinds of spraying method coating void ratios are bigger, the long-pending knurl of roll surface appearance after 2～3 months is generally used also without any processing in surface, spraying back, and because the coating bonding force is lower, coating is prone to generation and peels off.In addition, narrate in a lot of documents and in spray material, add CrB
2, CrB
2Really resisting dross has certain help, still, and CrB
2Fusing point lower; Generally about 800 ℃, can decompose, and form the boron of free state, these boron can be attached on the furnace roller surface of back low-temperature zone along with the walking of band steel; When low temperature (450-650 ℃); The manganese of boron and roll surface, iron, etc. combine, and solidify the compound that forms Mn-Fe-B, the roll surface that is attached on that this compound is firm is dross.
