Railway Tie Plates Definition:
Railway tie plates, also known as base plates, are thick plates made of steel, used between steel rails and sleepers or sleepers. Railway tie plates usually work with rail anchor bolts or railway spikes.
Advantages of Railway Tie Plates:
1. The railway sleeper distributes the load from the rail to the sleeper, and provides a uniform bearing surface for the rail and prevents the rail from moving.
2. Railway sleepers provide proper inclination, and obtain center load and more uniform wear on the rail head.
3. Railway sleeper plates firmly fix the rails to measure and protect the sleepers from excessive wear, thereby prolonging their service life.
4. The rail sleeper plates are made of heavy-duty hot-rolled steel profiles, which are stamped and cut to a certain size.
Railway Tie Plates Production Process:
1. Material Analysis
2. Material selection
3. Heating (forming)
4. Blank die forging edge punching
5. Thermal calibration
6. Surface shot blasting
7. Inspection of derusting packaging and storage
Types of Railway Tie Plates:
Railway tie plates can be classified according to single-shoulder structure or double-shoulder structure to provide various ribbed sleeper plates.
1. One-shoulder Tie Plates
For single-shoulder tie plates, the shoulder is designed at the field end of the plates. The short end of the plates or the distance end of the rail gauge is placed inside the rail, which is why customers always need the width of the bottom of the rail track. One-shoulder tie plates are usually used for rail weights ranging from 56 lbs to 100 lbs.
2. Shoulder Tie Plates
For double shoulder tie plates, 2 holes, 4 holes, 5 holes, 6 holes or 8 holes are available according to customer requirements. Shoulder tie plates are usually used for rails larger than 100 pounds.
3. Cast Rail Tie Plate
Casting is a common technology for the production of sleeper plates, and it is also a cost-saving method.
Name: cast steel rail sleeper plate
Type: Applicable rail UIC54, UIC60, 50kg rail, 60kg rail, S49 and order size
Material: QT500-7 or QT450-10 (forged low-carbon steel or high-carbon steel, rolled low-carbon steel S275JR, Q235, etc.)
Standard reference: UIC864-6
4. Base Plates of KPO Fastening System
The rail base plate is a key component in the KPO fastening system. It is used to support the rail and fix the entire fastening system. It is fixed on the track with rail bolts and rail spikes.
5.AREMA Standard Tie Plates
For the US market, common sizes are 11-inch, 14-inch and 14-3/4-inch tie plates, which are generally used for 5-1/2-inch and 6-inch wide rail bases.
6.AREMA Double Hook Tie Plates
HTTP, the full name is hook twin tie plate, is widely used in the turnout behind the bottom of the turnout. In order to ensure the tie spacing, HTTP often uses a single tie in pairs. Kingrail Parts is China's first manufacturer of 3/4 inch and 1 inch thick AREMA double hook tie plates.
Different available varieties:
For 3/4" hook double pull plate: L23, L27, L31, LR23, LR27, LR31, H23, H27, H31.
For 1-inch hook double tie boards: L29, L33, L37, LR28, LR32, LR36, H29, H33, H37, H41.
In the market, 3/4" and 1" thick varieties are the most popular in North America. Kingrail Parts has a modern production line, a workshop with modern characteristics, and an annual production capacity of 1000MTS.
7. Other Types of Rail Base Plates
Kingrail Parts can produce any other types of rail base plates or tie plates according to customer's drawings, full size and other technical specifications, including processing technology.
