Railway Fastener refer to tiny metal particles on the surface of the fastener that are burrs. How the  Railway Fastener  burr occurs when fasteners are formed during cutting, grinding, milling and other similar chip processing. In order to improve the performance and service life of the fasteners, it is necessary to remove the fastener burrs before using the fasteners. Fasteners are common components on mechanical equipment and are important components, so surfaces, sharp corners and edges need to achieve extremely high metal cleanliness. The main methods for removing burrs are: traditional mechanical processes, grinding, polishing and other processes with different degrees of automation. Railway Fastener It is also possible to remove the fastener burrs by a chemical process, so that the quality of the fasteners can be better ensured, and the fasteners are all sequentially immersed in a plurality of containers, one of which contains a chemical solution. With a simple ...

Fasteners are mainly divided into two types of manure: one is threaded fasteners; the other is non-threaded fasteners or couplings. This is only a brief description of threaded fasteners. Thread fastener processing processes are generally composed of cutting, cold rolling, or cold extrusion, cutting, thread processing, heat treatment, surface treatment and other production processes. The material remodeling process is generally: Pickling→drawing→annealing→phosphating saponification→drawing→(spheroidizing phosphating) Railway Fastening System With the development of domestic  Fastening System , competition from various provinces has become increasingly fierce, and the disorderly competition in the fasteners of the construction industry has begun to appear. The drawbacks of low cost, product structure and low technical content of embedded parts are also increasingly exposed. . In the 1980s, the threshold of the fastener industry in the construction industry was very low,...

     Anchor Bolt  is generally made of Q235 steel, made of round rebar, and many people should be familiar with it. For deep-buried diameters of 25mm 120mm hooks, if you know that bolt-welded square plates are a good If the finished product is used, then the hook will guarantee the basic friction of the bolt. What kind of characteristics do you have? Let's take a look today! Anchor Bolt 　　First, the anchor bolt 　  Alias stiffening anchor bolt, welding anchor bolt, foot bolt, foot screw, foot wire and so on. It is specially designed for burying in concrete foundations and is used for fixing various machines. It is also used in the  Railway Fastening System  for the base of the equipment. The 7-word anchor bolt is the more common one in the anchor bolt. It is generally made of Q235 steel. It is made of Q345B or 16Mn with high strength. It is also processed with 40Cr material with 8.8 grade strength, and occasionally with secondary or tertiary re...

　　To say that the purpose of  Anchor Bolt  is really very broad. Because of its good stability, it has been favored by the general public and has been widely used in some large-scale construction fields. I don't know how much you know about the anchor bolt. Let's take a look at  Anchor Bolt China Exporter . Let's take a look at the anchor bolt. If you want to know more about it, let's take a look! Anchor Bolt 　　Anchor bolt, the role of this bolt is to fix the machine on the ground. Because of its strong stability, it is often seen in bridges, mines, railways, highways, power companies, cement plants, automobiles, motorcycles, tower cranes, boiler steel structures, large-span steel structures and large buildings. 　　The role of the Anchor bolt is obvious, it is very important to understand the details of the anchor bolt. First, let's take a look at the material of anchor bolt. Generally, Q235 and Q345 are used to make anchor bolt. The strength of Q345 (that i...

　　 Anchor Bolt , the role of this bolt is to fix the machine on the ground. Because of its strong stability, it is often seen in bridges, mines, railways, highways, power companies, cement plants, automobiles, motorcycles, tower cranes, boiler steel structures, large-span steel structures and large buildings. Screws are one of the important components of the  Railway Fastening System , and the hardness of the screws often determines the quality of a mechanical device. The determination of the hardness of the screw is the heat treatment of the screw. 　　There are three kinds of heat treatment methods for screws. Today, I will tell you about the three heat treatment methods of screws. Anchor Bolt 　　1. Tempering heat treatment: The tempering heat treatment is mainly carried out by induction heating or flame heating. You can use two hardness testers to check the hardness of the screw, and then decide which standard heat treatment to use. The two hardness testers are Vickers har...
