Abstract
The invention discloses a technology for heating processing a C40 corrosion-resistant anti-wear material, comprising the following steps: putting a cleaned casting in a heat processing furnace according to the structure and wall thickness of the casting, closing the insulating furnace door, and powering for heating up; when the temperature reaches 450-550 DEG C, keeping warm for 1-1.5 h, then heating up to 740-780 DEG C and keeping warm for 2-2.5 h, taking the casting out of the furnace for air cooling, so as to obtain the casting with proper and uniform harness; when the temperature of the casting is cooled to room temperature and uniform, putting the casting in to the furnace again and heating up to 240-260 DEG C, and keeping warm for 4-4.5 h to eliminate the internal stress of the casting. The technology can ensure the C40 corrosion-resistant anti-wear material to achieve the mechanical properties that the design requires, and can eliminate the internal stress and ensure the product quality, and is beneficial to the production of products.
Description
Technical field; The present invention relates to a kind of thermal treatment process of C40 corrosion resistant wear-resistant material.
Background technology: because the general employed Working environment of pump is all very abominable, in order to increase the work-ing life of pump, so all need to adopt the corrosion resistant wear-resistant material, and corrosion resistant wear-resistant material price is all very expensive, the pump of producing as stainless material, and one will several ten thousand even hundreds of thousands of, general enterprise holds and dares not accept, and the pump that other alloy material is produced, not only price is expensive, and its intensity, hardness can not meet the demands.If it is bad that thermal treatment process is handled, there is internal stress in foundry goods, and casting hardness is inhomogeneous, is unfavorable for the mechanical property of processing, influencing quality product, do not reach design.
Summary of the invention: purpose of the present invention is exactly the thermal treatment process that a kind of C40 corrosion resistant wear-resistant material will be provided, and it can guarantee that the thermal treatment of C40 corrosion resistant wear-resistant material reaches the mechanical property of design.The object of the present invention is achieved like this, and the thermal treatment process of C40 corrosion resistant wear-resistant material is characterized in that: the foundry goods after at first will clearing up is rationally packed into by its structure, wall thickness situation in the heat treatment furnace, fastens the insulation fire door again, and power supply heats up; When temperature rises to 450-550 ℃, be incubated after 1-1.5 hour, be warming up to 740-780 ℃ again, be incubated 2-2.5 hour, it is air-cooled to come out of the stove, and obtaining suitable casting hardness, and makes casting hardness even; Treat air-cooled to room temperature, and casting temperature evenly after, go into stove once more and be warmed up to 240-260 ℃, be incubated 4-4.5 hour, the internal stress in the elimination foundry goods.The present invention can guarantee that C40 corrosion resistant wear-resistant material reaches the mechanical property of design.Eliminate internal stress, guarantee quality product, help product processing.
Embodiment:
The thermal treatment process of C40 corrosion resistant wear-resistant material is characterized in that: the foundry goods after at first will clearing up is rationally packed into by its structure, wall thickness situation in the heat treatment furnace, fastens the insulation fire door again, and power supply heats up; When temperature rises to 450-550 ℃, be incubated after 1-1.5 hour, be warming up to 740-780 ℃ again, be incubated 2-2.5 hour, it is air-cooled to come out of the stove, and obtaining suitable casting hardness, and makes casting hardness even; Treat air-cooled to room temperature, and casting temperature evenly after, go into stove once more and be warmed up to 240-260 ℃, be incubated 4-4.5 hour, the internal stress in the elimination foundry goods.During concrete enforcement, foundry goods is cleared up, rationally packed in the heat treatment furnace by its structure, wall thickness situation, fasten the insulation fire door again, power supply heats up; When temperature rises to 500 ℃, be incubated after 1.2 hours, be warming up to 760 ℃ again, be incubated 2.2 hours, it is air-cooled to come out of the stove, and can obtain suitable casting hardness, and makes casting hardness even; Treat air-cooled to room temperature, and casting temperature evenly after, go into stove once more and be warmed up to 250 ℃, be incubated 4.2 hours, the internal stress in the elimination foundry goods.
