Magnet Yoke of Induction Furnace

The magnet yoke is a yoke steel made of silicon steel sheet, which is evenly and symmetrically placed around the induction coil. Its function is to restrain the magnetic leakage of the induction coil from spreading outward, to improve the efficiency of induction heating, and to act as a magnetic shield to reduce the heat…

Calcium oxide and Steel-making

Calcium oxide also called burnt lime acts positive actions at steel-making process. Removal of hazardous elements S, P, Si, As Since oxides of sulfur, phosphorus, silicon and arsenic are usually some acidic substances, they are chemically combined with some alkaline substances to form relatively stable compounds. The lump calcium oxide…

Rolling mill for wire rod production line

Production Process of Wire Rod (for drawing material)

The wire rods are main materials of various drawing steel products. Due to the special use of the material, the purity of the steel shall meet the standard. otherwise there is a possibility of fracture during the drawing process. For example, the production process of ? 5.5 wire rod of…

Magnetism of Stainless Steel

Austenitic stainless steel (201, 202, 301, 304, 316) is non-magnetic or weakly magnetic, martensitic or ferritic stainless steel (430, 420, 410) is magnetic. Most of the stainless steel usually used as decorative pipe plate is austenitic, generally speaking, is non-magnetic or weakly magnetic, due to smelting composition bias or improper…

Electromagnetic Stirring (EMS) Technology

Continuous casting electromagnetic stirringㄗbrief EMSㄘ technology refers to the electromagnetic metallurgy technology, which is used to improve the quality of continuous casting billets by installing different types of EMS at different locations of the CCM. The generated electromagnetic force to enhance the flow of the liquid, thus change the heat transfer condition during the solidification of…

Q&A 200: Steel Making Deoxidation

Q: Why does the molten steel need to be deoxidized? A: If the molten steel is not deoxidized, the continuous casting billet will not have the correct solidification structure. High oxygen content in steel will also produce subcutaneous bubbles, loosening and other defects, and intensify the harmful effects of sulfur.…

Utilization Of Steel Slag

Steel slag can be used as blast furnace and converter raw materials in steel plants, and can also be used for road engineering, building materials, agricultural fertilizer and pit filling. In sintering ore with steel slag instead of flux, it can not only recycle the residual steel, FeO, CaO, MgO, MnO…

Typical Rolling Mill

Rolling mill is one of the most important equipment in steel plants. Modern advanced technologies provide the most possible to manufacture high quality mills. Here common mills are classified by the structure of rolling mills. 2-high mill The 2-high rolling mill has a simple structure and can reciprocate to roll…

Steel Bar Rolling Process 2

3. Slitting Rolling Process The slitting rolling is mostly used in bar continuous or semi-continuous rolling lines, and can greatly increase output of small-size rebar. This rolling process simplifies billet specifications and pass design, improves mill output, for the same section of the rolled part, comparing normal rolling process, the…

Steel Bar Rolling Process 1

Along with modern technology development, more and more steel entrepreneurs induce advance processes to improve product quality and plant efficiency. For steel bar production line, the following processes are used commonly. 1.Direct Rolling Billet Direct rolling technology is suitable for production lines to make plain carbon steel and low alloy…
