Where To Buy Slotted Angle Bar Singapore?

图片
When we use the Angle bar in industrial production, where can we buy the Angle bar cheaply? You need to know that our factory produces  Angle bar  with good quality and favorable price. Angle bar Angle bar, commonly known as Angle iron, is perpendicular to each other on both sides of the long steel bar. Angle steel is carbon structural steel used in construction. It is a type of steel with a simple section, mainly used for metal components and the frame of the workshop. Good weldability, plastic deformation performance, and certain mechanical strength are required in use. The raw material billet for Angle steel production is low carbon square billet, and the finished Angle steel is delivered in the form of hot rolling, normalizing, or hot rolling. Said method The specification of the width * width * side thickness of the mm number such as 50*50*5 can also be expressed as 5# Angle steel since the long shape sometimes followed by the length of equilateral Angle steel ...

Which Material Used In Railway Track?

The technology principle The track is subject to variable vertical, transverse and longitudinal static and dynamic loads, which are transferred from the rail to the roadbed by sleeper and roadbed. By means of mechanical theory, the stress and strain generated by each component of the track under various load conditions are analyzed and studied to determine its bearing capacity and stability. Track mechanics analyses the force and deformation of track structure under the action of locomotive and vehicle, as well as the influence of track structure diseases on track damage and train operation, so as to provide a basis for the design of track structure and the formulation of track management standards. The tracks The structure The track is composed of trackbed, sleeper,  rail , connecting parts, anti-climbing equipment, and turnout. Railway track Originally cast rails, developed into i-rails, the standard gauge (see track geometry) used by most of the world's railways...

What is a Railroad Track?

图片
Railroad Rail , the full name of the railway track, is a railway facility. Used on railways, and in cooperation with switches and turnouts, the train can walk without turning. The track is usually composed of two balanced steel rails. The rails are fixed on the sleepers, and the ballast is under the sleepers. Steel Track  is made of high manganese steel. The temper of manganese steel is very weird and interesting: if 2-3% manganese is added to the steel, the resulting low manganese steel is as brittle as glass and shatters when it is knocked. However, if> 13% manganese is added to make high manganese steel, then it becomes both hard and tough. So people use manganese steel to make wear-resistant machine parts and rails, bridges and so on. In addition, in the upper part of the rail, that is, the layer that is in contact with the wheel, another metal-indium is added, and its addition makes the upper part of the rail tougher when the hardness is guaranteed. This is very import...

UIC 54 steel rail exported to Argentina

图片
On 11th, Jan,2020, 600 tons EN13764-1:2011standard 18m length 54E1 rail were loaded into vessel, and heading for Argentina. As we are known, UIC stands for International Union of Railways. Since 1950, the flat-bottomed steel rails have been widely used in various countries. There are many used types all over the world. The differences between them lie in the detailed geometrical dimensions. The UIC standards were initially adopted in countries such as Europe and North Africa. Currently, they are generally accepted by the international community.

22kg Steel Rail and QU80 Crane Rail Exported to Brazil

图片
Since Nov 2019, we received the inquiry from Brazil client, After one month discussion, we reached the agreement. On 29th Nov, 2019, 50 tons of 22kg steel rail and QU80 steel rail were loaded into container and exported to Brazil. Which is expected to arrived at Brazil around 18th Jan 2020. In China, 22kg steel rail belongs to  Light Steel Rail . There are 8kg, 12kg, 15kg, 18kg, 22kg, 24kg, 30kg. The light rail is mainly used for the laying of temporary transportation lines and light locomotive lines for forest areas, mining areas, factories and construction sites.

Detection and Identification of Rail Surface Defects

图片
The operation of high-speed railways and heavy-duty railways has strict requirements on the reliability of railway infrastructure. As part of infrastructure inspections,  Steel Track  flaw detection plays a vital role in the safety of railway operations. In the past, most online rail fractures were caused by internal defects. Internal defects usually occur at the waist and head of the rail. With excessive wear and fatigue of the rail, internal defects continue to develop and expand, eventually leading to rail breaking accidents. Now with the introduction of advanced production technology, such as high-carbon steel and iron and steel production process. The probability of rail internal defects has been reduced a lot, and replaced by rail surface defects leading to rail fracture conditions are becoming more common. Steel Track The machine vision system proposed in this paper includes a simulated rail flaw detection operation platform, a high-speed linear array camer...
