A tie plate, also known as base plate or sole plate, which is a
steel plate that used between the steel rail and railway sleeper.
Tie plate basically has some holes and shoulder(s). But there is no
shoulder in some types of tie plate. Rail tie plate usually has
tapered side to improve the stability and reduce the twisting and
torsion of rails. There are close relationship between rail and tie
plate. Each tie plate is generally made for corresponding size of
rail. In another words, the tie plate has to be matched with width
of steel rail. As for the production process, tie plate can be made
by three processing ways: hot-rolled, casted and forged.
As one of the railroad components, tie plate is used to fix rail to
railroad tie and keep the rail safe. To be specific, the functions
of railroad tie plate as follow:
Tie plates transmit the load from steel rail to the railroad ties.
They provide even support surface for rail and prevent rail from
movement.
Tie plate helps the rail maintain their gauge, which keep the
safety of train running.
Tie plate reduce the friction between rail and railroad tie.
Tie plate protect railroad ties from excessive wear, so that
prolong their service life.
Tie plate provide proper cant and bear the central load.
We have manufactured e clip type baseplate in the way of rolling,
casting and forging. The e clip type baseplate are used in
combination of the elastic clip or shoulder.
