Description
Technical field
The present invention relates to wrapping material and field of production thereof, particularly relate to a kind of anti-oxidant wrapping material and preparation method thereof.
Background technology
Iron and steel parts must by workpiece heat to high temperature when completing the hot procedures such as rolling, forging, quenching, annealing, normalizing; under general atmosphere condition; iron and steel parts is subject to high temperature action usually can produce surface oxidation phenomenon, and simultaneously also can along with the dilution of alloying element.These phenomenons bring disadvantageous effect can to the mechanical property of workpiece and resistance to corrosion, have a strong impact on the work-ing life of workpiece.
According to statistics, the whole world has a large amount of iron and steel to report damage due to oxidation and corrosion.Wherein in heat processing technique, iron and steel oxidation loss is on average about about 10%.Thus must adopt an effective measure and prevent the oxidation of workpiece surface, thus improve hot-work quality.
At present for the feature of metallic high temperature oxidation, the most direct effective means is exactly the contact reducing metal parts and oxidizing atmosphere, and common method has several measures such as vacuum method, protective atmosphere method, high-temp antioxidizing paint method.Wherein vacuum method refers to that metallic substance is in hot procedure, workpiece is placed in the processing method of heated under vacuum.Under vacuum, oxidizing atmosphere substances content is few, prevents the carrying out of oxidizing reaction, thus prevents workpiece surface to be oxidized.Use vacuum method, first with vacuum pump, vacuum room air should be taken out, vacuum method technique is adopted to reduce workpiece oxidization burning loss ability highly significant, but adopt this method to have apparatus expensive again, many type of workpiece can not process, surface alloy element easily volatilizees, to shortcomings such as operator's level requirement are high, and the use range of this also this technique of influence power.Protective atmosphere method is carried out in few oxygen non-vacuum environment, and its principle reduces oxidizing atmosphere by being filled with shielding gas, stops oxidizing reaction to be carried out, thus reach the object reducing iron and steel oxidization burning loss.General protective atmosphere has nitrogen, methane, carbon monoxide, hydrogen, rare gas element etc.Its preparation method have directly pass into shielding gas, charcoal burning, pass into Sweet natural gas, pass into industrial nitrogen, organic liquid cracking etc.High-temp antioxidizing paint protection method is before hot-work, by applying coating at workpiece surface, is prepared into coating.Under the high temperature conditions, coating is softened and then melting, forms fine and close protective membrane, stops high-temperature furnace gas to the infiltration of matrix, avoids the oxidizing reaction occurred because of the direct contact of furnace gas.In hot procedure, adopting the provisional protective cover of high temperature to protect matrix is a kind of thermal treatment resist technology grown up nearly decades.Relative vacuum method hot-working process and protective atmosphere hot-working process, this guard method has the features such as less investment, cost are low, simple to operate, strong adaptability.But it has the following disadvantages: first, the solvent that coating adopts generally all has volatility, and therefore, staff easily sucks toxic ingredient when operating, thus unhealthful; Secondly, coating not easily transports and preservation; Finally, for workpiece coating composition labor intensive resource is comparatively large, and efficiency is not high.
