In August 2011, the expanded license for the special equipment material manufacturing of steel plates for heavy steel boilers and pressure vessels successfully passed the expert review and identification. At this point, the company has the qualification to produce steel plates for boilers and pressure vessels with a maximum thickness of 80 mm. Production continues to be at the leading domestic level. Our boiler steel plate has been widely used in the LR FH36 boat hull materials manufacture of I, II, III pressure vessels and various pressure vessel reaction tanks.
LR FH36 boat hull materials,Main characteristics of 12Cr1MoV Steel: compared with 12CrMoV steel, 12Cr1MoV steel has higher oxidation resistance and thermal strength. The creep limit of 12Cr1MoV steel is very close to the endurance strength value, and it has high plasticity under the condition of endurance tension; the processability and weldability of 12Cr1MoV steel are good, but it needs to be preheated to 300 ℃ before welding, and stress removal treatment after welding. 12Cr1MoV steel is widely used in Superheater, header and main steam pipe of high pressure, ultra-high pressure and subcritical utility boiler.LR FH36 boat hull materials
S355J2 steel plate rolling process is controlled rolling process. In the rolling process, the ingot rolling temperature is 1000-1050℃; in the first stage, the low-speed and large reduction rolling process is adopted, the high-temperature stage is 950-1000℃, the rolling speed is 1.6-2.0m/s, the single reduction rate is 15-20%, and the cumulative reduction rate is 40-45%, so as to ensure sufficient deformation of ingot. In the first stage, the start rolling temperature is 910-930℃, and the finish rolling temperature is ≤ 870℃.As a basic building material, steel plates are currently widely used in automobiles, shipbuilding, chemical industry, aerospace and other fields. Reasonable selection of flaw detection methods to ensure the quality of steel plates is of great significance to safe production. Common defects of steel plates are folding, inclusion, shrinkage, air bubbles, delamination and cracks. These problems can be discovered in time through flaw detection.LR FH36 boat hull materials
