Abstract
The invention discloses a kind of nut improving non-oxidizability based on blackening process method, it is characterized in that, including following parts by weight of component: carbon 0.26 0.34, manganese 0.17 0.25, niobium 0.05 0.14, silicon 0.15 0.25, molybdenum 0.03 0.05, phosphorus 0.011 0.022, nickel 0.073 0.14, tungsten 0.032 0.045, stannum 0.07 0.08, slag modifier for refining 20 25, surplus Fe and inevitable impurity.The surface oxidation-resistant performance of the screw connector of the present invention, mechanical performance are strong, and corrosion resistance is good.
Description
Technical field
The present invention relates to machine components manufacture field, particularly relates to a kind of spiral shell improving non-oxidizability based on blackening process method
Female and preparation method thereof.
Background technology
Nut is exactly nut, is threaded together the part for playing the role of fastening, all manufacturing machines with bolt or screw rod
Tool must a kind of element according to the difference of material, be divided into several big types such as carbon steel, rustless steel, non-ferrous metal (such as copper).Example
As: self-locking nut, stop nut, locking nut, four paws nut, nut, nut, screw-in nut lock nut, thin bar screw are even
Connected nut self-locking hexagonal acorn nut, special fot screw nut, hexagonal crown thin nut, eyenut.Embedded annular knurl
The main operating type of copper nut is injection, is embedded into inside working of plastics or direct mold injection, if using mould after heating
Tool injection, the fusing point of PA/NYLOY/PET is all at 200 ° of more than C, and after inserted num is entered plastic by hot melt, temperature uprises rapidly, note
After molded, the rapid crystallisation by cooling of plastic body is hardening, if inserted num temperature is also in high temperature, that is possible to down to copper spiral shell
Female place contacted with working of plastics starts to get loose or crack occur.So all using the spiral shell of copper material in the injection of inserted num
Mother rather than carbon steel nut.
The intensity of nut and service life and the founding materials of bolt, and the various trace alloying elements in founding materials
The inseparable relation that has of quantity, the constituent that the Steel material that traditional bolt is used exists alloying element is mixed and disorderly,
Due effect can not be played, and traditional method for making steel there is also defect, cause the impurity in molten steel to be difficult to remove, affect spiral shell
Female many-sided mechanical performance, the especially using method of slag modifier for refining molten steel is improper, Chinese patent slag modifier for refining molten steel:
Application number: indicate a kind of slag modifier for refining molten steel in the patent document of 00107235.8, it contain (weight %): CaO20～
45%, Al2O320～45%, in metal Al, Si, Ca, Ba, Re one or more 5～15%, CaF24～6%, SiO2≤10%,
MgO≤10%.This slag modifier for refining can have the structure of fritting solid solution.The molten steel processed with this slag modifier for refining contains very
Low sulfur, oxygen and field trash, but to there is composition kind few for the slag modifier for refining in file, and preparation method is simple, it is difficult to reach
To preferable effect, and method is single, does not point out the scheme being combined with each other with other processing methods, does not the most point out simultaneously
Its follow-up machine casting and the complete supporting technology scheme of processing technique, herein in conjunction with prior art, provide raising nut whole
The complete machining technique of body mechanical performance.
Summary of the invention
The object of the invention is contemplated to make up the defect of prior art, it is provided that a kind of use the casting of multiple alloying element and
Become, use and utilize blackening process method, improve the carrying based on blackening process method of surface oxidation-resistant performance of screw connector
Nut of high antioxidant and preparation method thereof.
The present invention is achieved by the following technical solutions:
A kind of nut improving non-oxidizability based on blackening process method, it is characterised in that include following parts by weight of component: carbon
0.26-0.34, manganese 0.17-0.25, niobium 0.05-0.14, silicon 0.15-0.25, molybdenum 0.03-0.05, phosphorus 0.011-0.022, nickel
