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

What Are the Different Types of Steel Rails?

图片
Steel rails are an essential component of railway tracks, providing the necessary support for the movement of trains. These rails are manufactured from a variety of steel alloys and are designed to meet specific requirements of the railway track, such as durability, strength, and resistance to wear and tear. In this article, we will discuss the different  types of steel rails  used in railway tracks.   Carbon steel rails Carbon steel rails are the most common type of steel rails used in railway tracks. They are made from a combination of iron and carbon, with the latter content typically ranging from 0.7% to 1.5%. Carbon steel rails are affordable and can be easily manufactured in large quantities. However, they have a low resistance to wear and tear, which means that they need to be replaced frequently.   High-carbon steel rails High-carbon steel rails have a higher carbon content than standard carbon steel rails, typically ranging from 0.8% to 1.1%. This makes them harder and more re

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 installation s
