What is the adverse effect of phosphorus on steel properties?

 Phosphorus has a large segregation in steel. In the high phosphorus content, the plasticity and toughness are greatly reduced, especially at low temperatures, the "cold brittleness" is less obvious. Generally, this harmful effect of phosphorus is enhanced as the content of C, N, and O in the steel increases. Phosphorus also has an adverse effect on the weldability of steel. Briefly describe the characteristics and mineral composition of the middle slag during blowing. In the middle of the blowing process [C], [O] is intense, and the slag is prone to "back to dry". Its characteristics are high alkalinity and low ferrous oxide content. The mineral composition of the slag is: mainly dicalcium silicate and dicalcium silicate. When the lime is added, there is more free CaO. The higher the alkalinity, the larger the amount of dicalcium silicate, and the more free CaO, which is detrimental to the smelting effect. http://www.tjxysteel.com/news/adverse-effect-of-phosphorus-...

How to improve the quality of molten steel when smelting high-carbon steel?

 How to improve the quality of molten steel when smelting high-carbon steel? (1) High carbon, the end point carbon is controlled above 0.15%, reducing carbonation; (2) Minimize the content of P and S in molten steel; (3) Control the composition of molten steel to ensure Mn/Si ? 3.0 or more; (4) Under the conditions allowed by the continuous casting temperature, the tapping temperature should be lowered as much as possible to reduce the amount of slag discharged from the tapping. http://www.tjxysteel.com/news/improve-the-quality-of-molten-steel-517.html

Degreasing Method for Stainless Steel Pipes and Fittings

 Degreasing method for stainless steel pipes and fittings: 1. Degreasing method of stainless steel pipe Since the stainless steel pipe only needs to be degreased, in addition to the degreasing method of the carbon steel pipe mentioned above, the large-diameter pipe can also be degreased by wiping. It is not suitable to use cotton yarn when degreasing by wiping method, and use cloth, silk, glass fiber fabric, etc. whose fibers are not easy to fall off. Longer pipes can be scrubbed with a clean wire tie with a two-way drag to remove oil on the inner wall of the pipe. After degreasing, the surface of the degreasing part must be carefully inspected. It is strictly forbidden for the fibers of the organic fabric to fall into and adhere to the surface of the degreasing part. After the inspection is passed, the nozzle should be blocked immediately. 2. Degreasing method of stainless steel pipe fittings and valves According to the volume of the largest valve, use a steel plate to make a self...
