DH36 HP bulb flat is a kind of structural profile which is mainly used in shipbuilding industry. It is usually used as reinforcing bars of ship hull. DH36 HP bulb flat can save steel consumption and reduce manufacturing cost while improving the strength and stiffness of ship hull. With the development of shipbuilding industry, the market demand of DH36 HP bulb flat is increasing year by year, and DH36 HP bulb flat is a high value-added product, so it has broad prospects for development.
DH36 HP bulb flat is divided into two parts: ball head and web. Because of the serious asymmetry of the cross section shape of the DH36 HP bulb flat, the uneven deformation of the ball head and web during rolling is very strong, the stability in the pass is very poor, and it can be formed only after repeated rolling, which makes the yield of the DH36 HP bulb flat rolling only 75%~80%. This has put forward high requirements for the pass design and rolling pass deformation distribution of the DH36 HP bulb flat.
The asymmetry of the section shape of the DH36 HP bulb flat will also lead to the uneven distribution of temperature field in the cooling process of the DH36 HP bulb flat after rolling, which will cause the bending deformation of the DH36 HP bulb flat. When the bending deformation of DH36 HP bulb flat on the cold bed reaches a certain degree, it will disturb the normal operation of the cold bed and restrict the normal biting of the subsequent straightening process.
GB T 5312 Carbon and carbon-manganese steel seamless steel tubes and pipes are mainly for ship use, also known as shipbuilding steel pipes. Under GB T 5312, there are mainly 5 steel grades: grade 320, 360, 410, 460 and 490. Each grade covers three levels: I, II, III.
Angle steel, commonly known as angle iron, is a long strip of steel whose sides are perpendicular to each other. There are equal angle steels and unequal angle steels. The two sides of equal angle steel are equal in width. The unequal angle steel is also known as L shape profile steel.
Flat bar steel can be produced according to the user's needs, with fixed thickness, width and length. It can reduce the cutting process for users, reduce the consumption of labor and materials, and also reduce the processing loss of raw materials.
