Description
Technical field
The present invention relates to the thermal insulating material of metallurgy industry hot working wrought alloy, refer in particular to the thermal insulating material that is used for difficult wrought superalloy hot working forging.
Background technique
Refractory alloy is the necessary important meals materials of high-tech power plant such as modern aeroengine, rocket motor.It can bear big stress and long-term the use under high temperature (referring generally to 600～900 ℃), oxidizing atmosphere and exhaust gas corrosion condition.Because the alloying level height of refractory alloy, so the thermal processing distortion difficulty is bigger.Generally speaking, be difficult to the refractory alloy of hot working forging deformation (cogging, moulding), be referred to as awkward wrought superalloy.At present, both at home and abroad, the thermal processing distortion method of difficult wrought superalloy has three kinds: extrusion press cogging, Pressesforging forge, the hot rolling mill pack rolling; At home, the hot working forging deformation is hot worked main method of difficult wrought superalloy and means.
For the special steel enterprise that produces less-deformable alloy, when less-deformable alloy forges, if ingot blank or billet surface are not taked the insulation measure, will be difficult to avoid the generation of the remarkable crackle of blank (or severe crack), even cause the failure of hot working forging deformation.Its reason is: it is very narrow that less-deformable alloy can carry out the hot processing temperature scope of plastic deformation.With the GH742 refractory alloy is example, the permission maximum heating temperature of ingot blank or steel billet is 1150 ± 10 ℃, final forging temperature should be not less than 1050 ± 10 ℃ (otherwise the forging that just can't guarantee alloy is in state of plastic deformation), and in the production scene, the transfer process of alloy blank from oven to fast forging machine, actual cooling extent can reach 50～100 ℃ (relevant with factors such as the size of blank transfer velocity, blank, ambient temperatures); Be transferred to when alloy blank on the hammering block of fast forging machine, its temperature has only 1050～1100 ℃, perhaps, perhaps reduced to 1050 ℃ final forging temperature (cause and to forge) near final forging temperature (make to allow the time of forging too short, can't effectively forge).Therefore, alloy blank being taked the insulation measure, is the prerequisite (requisite measure and condition) that realizes that difficult wrought superalloy effectively forges.
At present, insulation measure commonly used (for realizing effective forging of difficult wrought superalloy) is the way of compound jacket, the thermal insulating material that is used for compound jacket is a corrosion resistant plate, adiabatic cotton, be characterized in: cover one or more layers adiabatic cotton earlier at ingot blank or forging stock surface, use steel plate (adopting corrosion resistant plate usually) to coat adiabatic cotton then, and the contacting point of welding steel (like this, steel plate has just formed the surface that a cover is fixed on adiabatic cotton on ingot blank or steel billet, by the adiabatic heat-insulation effect of adiabatic cotton to heating ingot blank or steel billet, thereby the insulation that can realize ingot blank or steel billet is forged.)。Advantage is: not only delayed ingot blank (or steel billet) significantly and be delivered to temperature drop the forging hammer transfer process from oven (numerical simulation calculation shows: GH4169 φ 170 * 450mm bar is heated to 1010 ℃, come out of the stove from oven and to be placed on the air three minutes, the temperature of bar outside that does not coat compound jacket thermal insulating material is than about 200 ℃ on the low side of the temperature that coats compound jacket thermal insulating material bar outside, demonstrate the good insulation effect of compound jacket thermal insulating material) to bar, also can significantly delay the temperature drop in the ingot blank forging process, thereby increased the hot working time of difficult wrought superalloy plasticity forging deformation, reached the production purpose of effective forging.Shortcoming is: (1) is long heating time, and energy consumption is bigger.This is because with regard to the insulation and heating of steel billet, compound jacket thermal insulating material is a double-edged sword, both the steel billet that has heated had good insulation effect, steel billet to not heating has heat-blocking action again, cause the steel billet warming velocity that coats compound jacket thermal insulating material to reduce (during heating) significantly, need prolong the heating time of steel billet significantly, generally need to prolong heating time and reach more than one times, the energy consumption in the time of will significantly increasing heating like this; (2) complex procedures, cost is higher.When ingot blank (or steel billet) coats compound jacket thermal insulating material, shear the suitable jacket steel plate of size, carry out the shaping of jacket steel plate, welding coats the steel plate of adiabatic cotton etc., and whole jacket operation is more loaded down with trivial details; In addition, for avoiding the severe oxidation of jacket steel plate when heating, generally need to adopt the higher corrosion resistant plate of cost.(3) during forging deformation, the control of steel billet shape is difficulty.Because the jacket steel plate is easily by ironed, when steel billet was in the open die forging deformation state, the size of compound jacket thermal insulating material (outer stainless steel sleeve, internal layer adiabatic cotton) cover is expansion significantly.And follow the gap of forging process and steel billet increasing, thereby lose the fixation of steel bushing adiabatic cotton.In this case, the internal layer adiabatic cotton also can fall from billet surface, thereby weaken the heat insulation effect of compound jacket thermal insulating material in forging process easily owing to following steel billet heating process to produce the part efflorescence; In addition, because the gap of steel bushing and steel billet is increasing, can influence operability to the control of steel billet shape.(4) be not suitable for the insulation distortion that two fire forge.Adopt the superpacket cover of steel plate+adiabatic cotton to be incubated forging, be fit to a fire and forge the insulation distortion, after a fire was finished, cover was scrapped at once, at this moment, in the face of the red-hot steel billet of distortion, was difficult to carry out immediately the real time operation of the second fiery compound jacket.
Summary of the invention
The present invention develops a kind of Pasting adiabatic cotton and preparation method thereof, the Pasting adiabatic cotton of development is that a kind of new material of heat-resisting insulation (can effectively stick on the surface of 800～1250 ℃ of solid metal materials under the high temperature, pressure processing to metallic material has good heat insulation effect), it replaces the internal layer adiabatic cotton, the compound jacket thermal insulating material of outer corrosion resistant plate (cover), be used for the insulation measure that less-deformable alloy effectively forges (fire forges or many fire forge), immediately stick on the surface of (red-hot) alloy ingot blank (or steel billet), the Forging Technology of alloy ingot blank is significantly optimized, and operability significantly increases.On the one hand, the alloy ingot blank that can avoid compound jacket is warming velocity disadvantage slowly in oven, thereby enhances productivity (promptly need not prolong heating time), and energy efficient, reduces production costs; On the other hand, owing in the forging deformation process, do not have the gap between alloy ingot blank and the thermal insulating material, the steel billet shape is convenient to control, and the alloy forging quality is significantly optimized.Fabricating cost is higher, operation is loaded down with trivial details, the technical problem of narrow application range (being applicable to that a fire forges) to have solved the compound jacket thermal insulating material (adiabatic cotton, corrosion resistant plate) that is used for alloy ingot blank insulation forging, realized the optimization production that less-deformable alloy forges, improve prouctiveness, reduced cost of goods manufactured.
