railfastening

Tension Clamp  is a bolt fastener system, which belongs to the elastic and detachable  Railway Fastener  of the sleeper with concrete retaining shoulder. It has the following structure characteristics: 1.A variety of elastic spike can be installed. With different friction coefficient rail cushion plate, to meet requirements of different line resistance. 2.The gauge is adjusted by using engineering plastics, and has insulation effect, reduce the number of parts, to avoid the influence of fastener.  3.The height adjustment of rail is realized through the cushion between the underlay and the concrete sleeper rail surface.

There are two kinds of track beams used to install track: one is a steel structure beam and the other is a concrete prefabricated beam. The installation method of the crane track is useful for the fixing method of the press plate, the fixing of the hook screw, the welding and the fixing of the bolt.  In order to adjust the horizontal direction, the holes on the  Rail Clamp  usually make a growth hole, and the vertical adjustment can be added under the rail. When the rail clamp is designed, it must be enough rigidity, and each plate can be made into a single hole or double hole according to the force. Only when the rail and track beam or the fixed steel cushion board on the track beam are welded in the way of welding, the car gear can be welded on the track. We are  Rail Clamp Manufacturer  and supplier in China. 

Jan. 19, 2018 Stainless steel  Railway Fastener  has their own requirements for the production of raw materials. Most stainless steel materials can be made of steel wire or bar for fastener production. So what is the principle of selecting material? 1.Requirements for mechanical properties of  Railway Fastening System  materials, especially strength. 2.The requirements for the corrosion resistance of the material should be standard. 3.the working temperature to the heat resistance of the material. 4.Requirement of processing performance for the production process.  5.Weight, price and purchasing factor and so on should be considered. After a comprehensive consideration of these five aspects, the applicable stainless steel materials are selected according to the relevant national standards.

From the classification point of view, the stainless steel is divided into austenitic stainless steel and martensitic stainless steel. 304 is a kind of austenitic stainless steel. Not all stainless steel is not magnetic, only pure austenitic stainless steel is not magnetic. The effective way to eliminate magnetism is solid solution heat. In the composition of austenitic stainless steel, the valuable alloy has many components, and the general price is higher than martensitic stainless steel. It can be determined by analytical chemistry and metallographic examination. When the cold deformation of stainless steel is easy to cause Martensite Precipitation, it is especially obvious for 18-8 steel. Martensitic stainless steel is magnetic and is often used to make medical appliance, cutlery, tableware and so on.
