Six Common Problems In The Cleaning Of Railway Fasteners

In order for railway fasteners to function better, regular maintenance is required during use. Regularly cleaning the fasteners will increase the efficiency of the fasteners. As a Rail Spike Manufacturer, let us introduce the six common problems in Railway Fastening System cleaning.

1. Pollution when rinsing

Cause: Rinse is not caused by silicate remaining on the surface of the fastener.

2. Unreasonable stacking of fasteners

Cause: The fastener is contaminated by cleaning agents and quenching oil during the rinsing period, melts at the heat treatment temperature, leaving a chemical burn scar, which confirms that the surface of the fastener is not clean.

3. Surface residue

Cause: No acid cleaner was cleaned and the concentration of lye in the rinse tank was not frequently checked.

4. Alkali burns

Cause: The red area on the tested screw is caused by alkali burn. The alkaline cleaner contains chloride and calcium compounds, which will burn the steel fasteners during heat treatment and leave marks on the fastener surface.

5. Improper rinsing

Cause: Analysis by infrared spectrometer confirmed that in addition to iron oxide, there are sodium, potassium and sulfur, indicating that the inside of the fastener has an alkaline cleaning agent, which is likely to be potassium hydroxide, sodium carbonate or the like to promote its growth. rust.

6. Excessive corrosion

Cause: The infrared spectrometer was used to analyze the residual particles on the surface and found to have a higher concentration of sulfur and calcium.
