What Is The Wavy Wear Of Heavy Rails?

The heavy steel rail wavy wear refers to the wavy uneven wear on the top surface of the rail, which is essentially a wave-shaped crush. Wave grinding will cause high wheel-rail dynamics, accelerate damage to rolling stock and rail components, and increase maintenance and repair costs. In addition, the train's severe vibration will make passengers uncomfortable. In severe cases, it will also threaten driving safety. Its development speed is faster than side grinding, which is the main reason for the change in rail.
Wave milling can be divided into the short wave and long wave. The corrugation is a periodic irregularity with a wavelength of about 50 to 100mm and an amplitude of 0.1 to 0.4mm; a long wave is a periodic irregularity with a wavelength of 100 mm or more and 3000 mm or less and an amplitude of 2 mm or less.
The wave grinding mainly occurs on heavy-duty transportation lines, especially in coal transportation and transportation lines. It also occurs in different degrees on high-speed passenger lines and is also common in urban subways. In general, the dynamic effect is the external cause of the formation of the rail wave, and the material properties of the rail are the internal factors of the wave grinding.

Steelmaking Process (2)

8. Refining period: The process of steelmaking is carried out by slagging and other methods to remove some elements and compounds that are harmful to the quality of steel by chemical reaction into the gas phase or discharged into the slag to remove it from the molten steel. period. 9. Reduction period: In the ordinary power electric arc furnace steelmaking operation, the time from the completion of the slag slag to the tapping is usually called the reduction period. 10. Furnace refining: The steelmaking process of refining the molten steel in the steelmaking furnace (converter, electric furnace, etc.) to another vessel for refining, also called secondary metallurgy. The steelmaking process is therefore divided into two steps: primary refining and refining. 11. Steel liquid agitation: Stirring of molten steel through refining beyond the furnace. It homogenizes the molten steel composition and temperature and boosts metallurgical reactions. Most metallurgical reaction procedures a...

Crane rail installation - Standards and procedures

图片
   Introduction to crane track installation With the rapid development of modern logistics, greater demands are being placed on the logistics management of machinery and equipment. This is not just about transporting bits. Once heavy machinery or equipment has arrived at a facility, it also needs to be picked up, moved and set up appropriately. For these purposes, cranes come in very handy. As cranes play an important role, crane track installation also plays an important role in these industries.  Crane track installation Techniques and standards The accurate installation of crane rails is a primary requirement for this type of heavy machinery and related industries. Selecting the most suitable track and securing it is a key issue in ensuring the integrity and longevity of the crane track system. At Yongyang , we have a reliable, skilled and experienced team to help you find the more suitable crane rails. But more on that later. Now let's talk more about crane rail inst...
