What is the material used in the rail clip?

SINCHOLD Port Engineering Co.,Ltd | Updated: Oct 18, 2017

The material used for the rail clip is cast steel.

Cast steel is a general term for the production of ferrous alloys that do not undergo eutectic transformation during solidification. A form of casting aluminum alloy. Cast steel is divided into casting carbon steel, alloy steel and cast steel.

1. Cast carbon steel. The cast steel is made of charcoal as the main alloy element with a small amount of other elements. Carbon content of less than 0.2 percent is cast low-carbon steel, carbon 0.2 ~ 0.5 percent is casting carbon steel, more than 0.5% of which is high carbon steel. With the increase of carbon content, the strength of cast carbon steel increases and the hardness increases. Cast steel with high strength, good plasticity and toughness, the characteristics of low cost, used in heavy machinery parts, mill tripod, big load, such as hydraulic base used in railway vehicle manufacturing large and carrier effect components, such as intensity, side frame, wheels and coupler, etc.

2. Cast alloy steel. Cast steel with manganese, chromium, copper and other alloy elements. The total amount of the alloy element is generally less than 5%, which can have higher impact hardness and better mechanical properties through heat treatment. The performance of casting alloy steel is better than carbon steel, which can reduce the quality of parts and improve life.

3. Cast special steel. In order to meet the special needs of alloy steel cast steel, a wide range, which usually contains one or more high alloy elements to achieve special performance.Containing 11% ~ 14% of manganese, for example, can impact wear, high manganese steel is mainly used in mechanical mining, engineering, machine parts, durable, chromium or nickel chromium as the main elements of alloy, with a wide range of stainless steel, corrosion or high temperature above 650 ℃ condition of artifacts, such as chemical, pump, valve shell, such as containers or large capacity power plant steam turbine casing.

By rail clip is meant for the crane rails firmly fixed connecting piece with the ground, it placed along the path length, every 500 mm set a group, a group of pay, for two symmetric sets in on both sides of the track, in crane operation state, it can essays straight and lateral impact. It is necessary to pay attention to the safety and maintenance work during the use of the rail clip.
