Problems solved by technology

In addition, during the stacking and transportation of finished rail products, the rail tread is prone to water accumulation, while the rail waist and rail bottom are not easy to accumulate water, so the rail tread is the most likely to rust

preparation example Construction

[0018] The production process of the corrosion-resistant steel rail provided by the invention is simple, and only needs to uniformly coat the anti-rust oil on the surface of the steel rail substrate, and then stack at ambient temperature. For industrialized continuous production, the specific operations of the preparation method of the corrosion-resistant steel rail include: on the rail substrate conveying track line, evenly apply anti-rust oil on the surface of the rail substrate to obtain the corrosion-resistant rail of the present invention. Wherein, the mode of coating anti-rust oil is not particularly limited in the present invention, can adopt various methods well-known by those skilled in the art to evenly coat anti-rust oil on the surface of the rail base body, the mode of described coating anti-rust oil It can be any one of manual brushing, automatic brushing, roller coating or air pressure spraying. The coating amount of anti-rust oil is such that the thickness of th...

Embodiment 1

[0022] This embodiment is used to illustrate the corrosion-resistant steel rail provided by the invention.

[0023] (1) Preparation of antirust oil

[0024] Add 75 parts by weight of castor oil in the reactor, add 10 parts by weight of magnesium lanolin soap after being warmed up to 160 ° C, and stir at this temperature for 1.5 hours, add 14 parts by weight of barium petroleum sulfonate and 1 parts by weight of zinc naphthenate, and stirred at this temperature for 2 hours, then cooled to 45° C. and filtered through a 60-mesh stainless steel wire filter, and the resulting 99.5 parts by weight of filtrate was the antirust oil to be obtained.

[0025] (2) Production of corrosion-resistant steel rails

[0026] On the 55 kg / m rail substrate conveying track line, the anti-rust oil prepared in (1) is evenly coated on the surface of the rail substrate by air pressure spraying. The thickness of the cloth was 50 micrometers, thereby producing a corrosion-resistant steel rail A1.

Embodiment 2

[0028] This embodiment is used to illustrate the corrosion-resistant steel rail provided by the present invention.

[0029] (1) Preparation of antirust oil

[0030] Add 62.7 parts by weight of castor oil to the reactor, add 12 parts by weight of magnesium lanolin soap after heating up to 120°C, and stir at this temperature for 2 hours, add 17 parts by weight of barium petroleum sulfonate after natural cooling to 75°C, 8 parts by weight of barium dinonylnaphthalene sulfonate, 0.1 part by weight of N-oleoyl sarcosine stearylamine, 0.1 part by weight of dodecenylsuccinic acid and 0.1 part by weight of zinc naphthenate, and stirred at this temperature After 3 hours, it was cooled to 40° C. and filtered through a 60-mesh stainless steel wire filter, and the obtained 99.3 parts by weight of the filtrate was the antirust oil to be obtained.

[0031] (2) Production of corrosion-resistant steel rails

[0032] On the 43 kg / m rail substrate conveying track line, the antirust oil prepar...

Abstract

The invention provides an anti-rust steel rail. The anti-rust steel rail comprises a steel rail matrix and an anti-rust coating coated on the surface of the steel rail matrix, and the anti-rust coating is a film layer formed by coating the anti-rust oil on the surface of the steel rail matrix, wherein the anti-rust oil contains base oil and an anti-rusting agent, the base oil is castor oil, and based on the total weight of the anti-rust oil, the content of the castor oil is 60 to 84 percent, and the content of the anti-rusting agent is 16 to 40 percent. The anti-rust steel rail has excellent short-term anti-rust effect, and because the anti-rust oil, which is high in flash point and uses the castor oil as the base oil, is used in the production of the anti-rust steel rail provided by the invention, the safety of producing the anti-rust steel rail is quite high.

Description

technical field [0001] The invention relates to a corrosion-resistant steel rail. Background technique [0002] After the steel rails for railways are produced by iron and steel enterprises, they need to be transported by rail (or by sea) to reach the user. The user also needs to weld them into 250m~500m long rails and stack them, and then transport them to the railway line with a long rail car for track laying. It will take some time until the railway is officially put into operation. Generally, the cycle from the delivery of the rails to the official operation after laying the rails is generally within one year. Under normal circumstances, during the transportation process of ordinary steel rails after leaving the factory, especially in ocean shipping under marine environmental conditions, due to the sun and rain under natural conditions, the surface of ordinary rails has begun to rust and turn yellow after reaching railway users, so that During the period from the rail l...
