Our company's hot rolled RINA DH40 marine plate power boilers, heating furnaces of double bars, double high lines and medium and thick plates all adopt heat storage technology, which can fully use blast furnace gas; the ladle baking, Maerz active lime kiln and medium and thick plate heat treatment furnace all burn converter gas, which can improve the hot rolled RINA DH40 marine plate utilization rate of secondary energy and realize negative energy steelmaking in steelmaking process.
The annual sales volume of steel product is over 300,000 tons, and the sales volume has increased year by year. The business scope covers the Southeast Asia, Eastern Europe, Middle East, Africa, North America, and South America. Client services are mainly in the petrochemical, wind power, shipbuilding, steel structure, machinery manufacturing, and construction industries. Throughout the process, we provide customers with professional personal steel customization services and one-stop solutions, professionally set a variety of futures, fast delivery, and excellent prices.
S355J2 steel plate hot rolled RINA DH40 marine 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 hot rolled RINA DH40 marine plate 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℃.
In year 2015, we supplied 950 tons S355J0 angle steel to Egypt government. We have cooperation with local government for more than 3 years. Every year, they would order more than 3000 tons of hot rolled RINA DH40 marine plate steel from our company.
Hot Rolled Plates hot rolled RINA DH40 marine plate MachiningAfter final forging/forming and Heat treatment process, all the pipe Fittings, Flanges, Fasteners, Etc. are sent for machining i.e. and preparation, O/D and I/D matching as per dimensional codes. An Expert Q.C. engineer is involved and he keeps constant vigil on every machining operation. Step machining is carried out as required by the codes. GO and NO-GO gauges are used to check the O/D & I/D of the fittings, Flanges, etc.
