Blast furnace ironmaking is a traditional ironmaking method based on coke energy. It cooperates with converter steelmaking and is the main method of producing NV D40 hull steel material steel at present. This dominance of blast furnace ironmaking is not expected to change for quite a long time. The essence of blast furnace ironmaking is the reduction of iron. Besides, coke is used as fuel and reducing agent. At high temperatures, iron ore or iron-containing raw materials are reduced from an oxide or mineral state to liquid pig iron.
SA299 Gr.B steel is C-Mn-Si steel plate often used to make various welding parts whose working temperature does not exceed 400 degrees Celsius, such as the head and shell of boiler steam drum, pressure vessel. Due to its working environment, SA299 Gr.B plate is required to have a higher medium temperature, outstanding shaping and heat treatment process functions, and outstanding welding functions.
Our quality control department will do inspection for details of the steel materials NV D40 hull steel material before delivery. We would invite the customer side to attend the inspection together. If they can not come, we will also take rich pictures for them to check. Meanwhile, we will publish inspection report and send them the PDF version. Besides, we accept any third party inspection such as SGS, BV, etc. And our quality control department will support the third party to inspect the steel materials smoothly and try our best to deliver the qualified steel materials to customers earlier.
Our company will accept the product quality objection registration record, pass it to the NV D40 hull steel material production unit and relevant departments, and timely coordinate the supervision of product NV D40 hull steel material quality objection. Our company coordinates the relevant department personnel to the customer unit to carry on the investigation, the processing.
Strengthen system construction. The system itself has a certain binding force, which specifies the rights and obligations of employees. It is a passive management means for employees. Its purpose is to promote each employee to develop good professional habits, form good behavior norms, and promote the improvement of enterprise management level.
