At present, the company has successfully developed and produced more than 10 kinds of boron-containing steel varieties such as 35MnBM, 23MnBM, CCS A40 bulk ore carrier steel, 27MnTiB, 40MnB, 25CrMoTi, etc. According to the practice of Laiwu Steel's 50t electric arc furnace-50t LF-60t VD-R11 Lianzhuo-VD Royal alloying process development and production of boron-containing steel, the technical measures for precise control of the smelting of boron-containing steel are analyzed and discussed.
Boiler steel plates for room temperature and medium temperature (below creep temperature) are mostly carbon steel, including carbon steel, carbon manganese steel, carbon manganese silicon steel, CCS A40 bulk ore carrier steel, etc. They are mainly used in the manufacture of pressure-bearing parts such as boiler drums and header end covers below medium temperature. High temperature (above creep temperature) boiler steel plates are mainly used to manufacture high-temperature pressure-bearing parts such as high-temperature header end caps and steam pipe blocking plates.
The main function of boron in CCS A40 bulk ore carrier steel and so on steel is to increase the hardenability of steel, so as to save other rare and precious metals, such as nickel, chromium and molybdenum. For this purpose, the boron content is generally regulated in the range of 0.001% - 0.005%. It can replace 1.6% nickel, 0.3% chromium or 0.2% molybdenum. It should be noted that molybdenum can prevent or reduce temper brittleness, while boron slightly promotes temper brittleness, so molybdenum can not be completely replaced by boron.
T11 steel is a steel grade produced according to American Standard ASTM A213. T11 steel is used for boiler, superheater and heat exchanger tubes with minimum wall thickness. Chemical composition of ASTM A213 T11 steel: C 0.05-0.15, Si 0.50-1.00, Mn 0.30-0.60, P, S ≤ 0.025, Cr 1.00-1.50, Mo 0.44-0.65. Mechanical properties of ASTM A213 T11 steel: tensile strength ≥ 415 Mpa, yield strength ≥ 170 Mpa, elongation ≥ 30%. The main ASTM A213 steel pipe grades are A213 T11, A213 T12, A213 T22, CCS A40 bulk ore carrier steel, etc.
