Abstract
The invention provides a method for eliminating switch rail sparks and an anti-spark paint used by the same, and aims to overcome the defects in the existing switch rail. The method for eliminating switch rail sparks is implemented by respectively brushing an anti-spark paint coat on the seam between the switch rail upper jaw and the reinforcing plate edge. The paint coat has favorable conductivity and flammability, and can effectively enhance the conducting power of the switch rail edge and reinforcing plate edge. The anti-spark paint is mainly prepared from the following components in percentage by weight: 50-60% of graphite powder, 20-15% of water glass, 20-15% of N32# machine oil and 10% of lime grease. The preparation method is simple and easy to operate; and after the heat treatment, no residues difficult to clean are left on the surface of the switch rail. The invention has the advantages of low cost, favorable effect, no environmental pollution, no irritating smell, no toxicity and no adverse effect on construction personnel.
Description
Technical field
The invention belongs to railroad track accessory manufacturing technology field, the particularly improvement of railway switch tongue.
Background technology
In 43Kg/m, the manufacturing of 50Kg/m track switch product were produced, during stiffening plate tongue (as shown in Figure 1) induction quenching of U71Mn material, phenomenon was burnt in normal generation upper edge, Hubei Province sparking, became puzzlement track switch product thermal treatment quality one large persistent ailment.Major cause is that tongue 20mm section is about 1mm to the slit between the most advanced and sophisticated stiffening plate maxilla edge, position, because the effect of electromagnetic induction, tongue edge and stiffening plate edge produce high-voltage and strong eddy current, punctured air between the slit, moment produces the spark discharge fever phenomenon, has caused tongue side stiffening plate that meniscate burn is arranged.
Summary of the invention
The object of the invention is to provide a kind of method and anti-sparking coating thereof of eliminating the tongue sparking, the defective that exists to solve existing tongue.
Eliminate the method for tongue sparking, it is the anti-sparking of brushing one deck dope layer respectively in the slit at tongue maxilla and stiffening plate edge, and described dope layer has good electroconductibility, combustibility, and can effectively strengthen tongue edge and stiffening plate edge conductive capability.
Described anti-sparking coating, it is mainly by graphite, water glass, machine oil forms, and its weight percent is: Graphite Powder 99 50～60%, water glass 20～15%, N32# machine oil 20～15%, quicklime grease 10%, each component adds up to 100%.
A kind of method and anti-sparking coating of eliminating the tongue sparking of invention.This paint brush at place, tongue slit, has been eliminated heat-processed MR medium reinforcing plate tongue maxilla edge and produced the meniscate scar that sparking causes because of spark discharge.Obtain aborning at present experimental applications, obtained significant effect.The present invention not only preparation method is simple, and operation is succinct, and thermal treatment metacone track surface is cleared up residue without difficulty, and cost is low, effective.And non-environmental-pollution, have no irritating odor, nontoxicity, to the workmen without any detrimentally affect.
Description of drawings
Fig. 1 is band stiffening plate tongue synoptic diagram of the present invention.
Embodiment
A kind of coating of the present invention, mainly by graphite, water glass, the compositions such as machine oil, its weight percent is: Graphite Powder 99 50～60%, water glass 20～15%, N32# machine oil 20～15%, quicklime grease 10%.Be stirred into paste, brushing gets final product in the slit at tongue maxilla and stiffening plate edge.
Concrete recipe ratio is such as Graphite Powder 99 60%, water glass 15%, N32# machine oil 15%, quicklime grease 10%.
Concrete prescription also can be Graphite Powder 99 50%, water glass 20%, N32# machine oil 20%, quicklime grease 10%.
During implementation, brush a coating with 1 cun hair plates brush at the stiffening plate point of switch respectively to the slit of 20mm section, because the graphitiferous powder is more than 50%～60% in the coating, the water glass of auxiliary improvement, so coating has fabulous electroconductibility, combustibility, can effectively strengthen tongue edge and stiffening plate edge conductive capability, eliminate the spark discharge phenomenon.This coating can be brushed at normal temperatures, and is easy and simple to handle.
Claims (2)
1. eliminate the method for tongue sparking, it is characterized in that in the slit at tongue maxilla and stiffening plate edge the respectively anti-sparking of brushing one deck dope layer, and described dope layer has good electroconductibility, combustibility, and can effectively strengthen tongue edge and stiffening plate edge conductive capability.
2. as claimed in claim anti-sparking coating is characterized in that it mainly by graphite, water glass, and machine oil forms, and its weight percent is: Graphite Powder 99 50～60%, water glass 20～15%, N32# machine oil 20～15%, quicklime grease 10%, each component adds up to 100%.
