The measured results fully meet the standard technical requirements.
2. The hydrogen content is less than 1.0ppm, which meets the requirements of die steel and is less than or equal to 2.5ppm, and other steel types are less than or equal to 3.0ppm.
3. The oxygen content is less than 0.0050%.
4. After the ingot is processed, the ultrasonic testing all reach the (GB\/T13315-1991) level 2 standard.
5. Comparison of mechanical properties between refined and unrefined stainless steels such as 304: (GB\/T328-2002)
1) The tensile strength before refining is 549.53Mpa, and after refining, 606.82Mpa is increased by 57.29Mpa
2) Yield strength before refining 270Mpa after refining 339.52Mpa increased by 69.52Mpa
3) 38.46KN before power refining, 49.10KN after refining, increased by 10.64KN
A few notes:
a) Since the argon blowing time for each furnace is 510mm, argon blowing is carried out after the addition of gold, and the tapping after blowing will not affect the smelting time and will not increase the power consumption.
b) The removal of [N] [H] [O] by blowing argon does not have a chemical reaction, which not only does not shorten the life of the furnace lining, but also prolongs the life of the furnace lining due to the homogenization of the melt temperature in the furnace.
c) Argon is an inert gas and is very safe to use.
In a nutshell: the medium frequency induction furnace refining technology marked by the use of gas diffusers is a production process with less investment, quick effect, low cost and high quality. It is an energy-saving and environmentally friendly production process and a short process. The production process. Based on this technology, with the protection of the casting process, high-quality castings and steel products can be produced.
