Description
Technical field
The present invention relates to paint field, specifically, relate to a kind of high temperature resistant adhesion resistant steel nano ceramic powder coating.
Background technology
Oxygen lance is a kind of Self comsuming oxygen blast instrument as inserting bath lancing during steelmaking oxygen blowing from fire door, in China's electric furnace and part openhearth steelmaking are produced, is widely used by as main oxygen blast instrument.Because steelmaking oxygen blowing requirement condition is very harsh, usual oxygen lance inserts the molten steel bath surface of temperatures as high about 1200-1500 DEG C, oxygen lance is in oxygen blast process, and the molten steel risen shoots down rifle head in remaining about 10 meters and the body of a gun, causes that oxygen lance tube wall is sticky inhales molten steel thus.The outer tube wall of oxygen lance wrap up by sticky slag entirety of inhaling, thickness roughly evenly, steel bonding thickness average out to 100mm-150mm, length at rifle head in 10 meters, the body of a gun.
Oxygen lance outer tube wall steel bonding reason mainly contain following some: first, tubing stretches into furnace high-temperature environment instantaneously by the low-temperature condition of natural temperature environment, tube wall temperature is lower than molten steel in the stove temperature, therefore the molten steel risen is when meeting the lower pipe outer wall of temperature, at once produce shrinking percentage and adhere to immediately on pipe outer wall, and successively increasing; The second, the quick heat radiating effect receiving interior water-cooled layer closed by overcoat, and himself temperature all the time lower than in-furnace temperature, therefore constantly adsorbs the slag liquid risen, and successively increases; 3rd, the rate of expansion of canister material self, because receiving the slag liquid parcel successively adhered to, its rate of expansion also suffers restraints and limits; 4th, because the steel bonding coating of pipe box trypsin method is thinner, it receives the impact that molten steel splashes landing unexpectedly, and there is damage situations gradually coating appearance local, and to coating, impaired place still has molten steel adhesion layer.A molten steel bath is equipped with two oxygen lances usually, and two oxygen lances use in turn, midfeather 30-40 minute.Oxygen lance is when completing once the oxygen blast process of about 20-30 minute, the whole outside surface of oxygen lance sticks molten steel and slag, at another root oxygen lance on period, usually at high temperature manually clear up fast, labor strength is increased, person works's increased risk, productivity effect reduces, cause the oxygen lance of delivering oxygen to consume in a large number, make oxidizable melting loss of elements serious.Therefore, gluing and protection function by improving oxygen lance outside surface burn-out-proof, for the work-ing life extending oxygen lance, reducing the consumption of oxygen, there is very important economy and realistic meaning.
Through retrieval, Chinese patent ZL:201010540381.4, denomination of invention is: high-temperature burning sticking preventing coating, consisting of of described high-temperature burning sticking preventing coating: organosilicon crylic acid latex 3.0 ~ 8.0%, graphite 15.0 ~ 25.0%, molybdenumdisulphide 1.0 ~ 5.0%, rare earth cerium fluoride 1.0 ~ 3.0%, metal oxide 5.0 ~ 10.0%, aerosil 1.0 ~ 3.0%, potassium pyrophosphate 0.1 ~ 0.2%, surplus are water.The burn-out-proof stick coating in this invention glues and protection although can realize having burn-out-proof to oxygen lance surface, but because this coating is water soluble paint is again be coated in oxygen lance surface by common brushing mode, coating easily comes off, and can only use and make for 1-3 time, work-ing life is short.
