As a  Rail Spike Manufacturer , share with you. There is a process in the  High Strength Bolt  manufacturing process to improve the comprehensive mechanical properties of the fastener, which is the heat treatment process. This process has a very important impact on the quality of high-strength bolts, especially the inherent quality of high-strength bolts. Processing and producing a high-strength bolt has a very complicated process, and high-strength bolts that pass multiple processes and are strict in each process can be regarded as basically qualified. In order to fully meet the pre-designed standards, more rigorous inspections, reasonable storage, transportation, and correct installation are required before finally realizing the true role of a high-strength bolt. High Strength Bolt In the process of heating the billet, the phenomenon that the carbon content of the surface metal is reduced or even does not contain carbon due to oxidation is called decarburiz...

As a  Railway Fastening System , share with you. Anchor bolts are one of the fasteners. They are responsible for all kinds of construction and equipment. The anchor bolts are generally attributed to the embedded bolts, which are buried in the lower part of the concrete to serve as the foundation. Anchor Bolt Anchor Bolt  has a variety of shapes, some are L-shaped, and some are Arabic numeral nine. The anchor bolts of different shapes also have different intermediates, of course, there are very different intermediates. Everywhere in the slender middle is a round surface for grasping precision, different foundation bolts are used in different structures and different constructions of different equipment. First, the ruler must be accurately controlled when arranging the ruler, and the fixed person has been arranged to compete for the ruler. Secondly, the fixed mold can be made according to the embedded size of the bolt to ensure that the relative orientation of the bolt ...

Rail Spike Manufacturer  knows the use of bolts, knowing that there will be many misunderstandings in the use of bolts, so that everyone's views on the use of bolts cannot be obtained in the correct way. In many cases, we need to think carefully before using bolts, which will help the performance of bolts and mechanical equipment. Steel Bolt 1.Substituting coarse to fine: Some important couplings, such as transmission shafts, fly shafts, etc., are mostly bolts with fine pitches and fine pitches. The pitch and outer angle of the bolts are small, and they have the advantages of high strength and good self-locking performance. After the coarse tooth bolt is replaced, it is easy to be loosened, detached, and disassembled, causing an accident. 2.The pores do not match: Bolts that can withstand lateral loads and shearing forces (such as drive shaft bolts and flywheel bolts) .The fit between them and the bolt holes is a transition fit. If you do not pay attention to the ins...

Many people in the process of using  Railway Fastener , think that a small fastener replacement will not change much. As everyone knows, this idea is incorrect. As a mechanically important component, fasteners must be strictly installed in different types according to requirements during use.If other similar fasteners are used instead, it is likely that Will cause accidents in machinery and equipment, and even safety accidents. Therefore, we must pay attention to the use of fasteners. Based on our understanding,  Rail Spike Manufacturer  tells you that in these eight cases, many people will mistakenly believe that the use of fasteners is correct, but it is not. Railway Fastening System  In these eight cases, the use of fasteners is incorrect: 1. Use fine teeth instead of fine teeth There are many important connecting parts on the machine, such as drive shafts, etc. Most of the bolts are fine-threaded. If there are missing parts during maintenance, some mai...
