In the production process of ASTM A283C low carbon steel sheets, problems such as excessive inclusion, large size, side wave and medium wave often occur.
According to practical experience, BBN steel proposes the following quality optimization measures:
First, Chemical composition of ASTM A283C low carbon steel sheets:
The content of harmful carbon, Mn and Als should be reduced as far as possible, the content of Si should be reduced as far as possible, and the control requirements of N should be improved, so as to reduce the fluctuation of related manganese and Als.
Second, Production technology of ASTM A283C low carbon steel sheets:
The conversion of iron water into converter requires full slag. Control the carbon at the end of the converter and increase the carbon drawing rate by about 55%.Use slag instead of slag ball to improve slag effect.
Third, rolling process of ASTM A283C low carbon steel sheets:
The slab heating temperature fluctuation control in 30 ℃, using high finishing temperature control of laminar cooling water. Even if single side adjustment, roll adjustment and reasonable roll bending force are set, the good roll shape of A283C steel sheet is ensured.
Through the above measures, the quality of A283C carbon steel sheets is greatly optimized. If you want to learn more about how to optimize quality of ASTM A283C low carbon steel sheets, welcome to consult BBN steel at any time.
