What are the special requirements for angle steel of power tower?
Power tower is used for transmission lines. The lattice tower mainly composed of angle steel is the supporting structure for supporting conductors and grounding wires. Make the conductor reach the limit distance requirement of ji to the ground and ground objects, and can bear the conductor, ground wire and its own contact surface and contact surface.
Usually called angle iron, it is a long strip of steel, with two sides perpendicular to each other to form an angle. It can be divided into equal edge steel and unequal edge steel. Two kinds of steel with the same side and width. Its specification is expressed in millimeters, and its side width × Edge width × Edge thickness. For example, "=30 × thirty × three ", that is, an equilateral angle steel with a side width of 30 mm and a side thickness of 3 mm. The model can also be used to indicate that it is cm of a side width, such as 3 #. The model cannot represent different edge thickness dimensions in the same model, so the edge width and edge thickness dimensions of the angle steel filled in the contract and other documents are complete, and cannot be represented by the model alone. The hot-rolled specifications of the equilateral angle steel are 2 # - 20 #. Various stressed parts can be made according to different structural requirements, or can be made Make connections between components.

Angle steel has good strength and low-temperature toughness at 857 and 873 ℃, while its low-temperature toughness value is very low at 924 and 986 ℃. At the final rolling temperature of 857 and 873 ℃, the angle steel will undergo ductile fracture at - 40 ℃ and brittle fracture at 924 and 986 ℃. Adding vanadium to Q420 can improve the strength of angle steel. The reason is that the vanadium and VC phases in alloy steel form precipitation strengthening, forming precipitation strengthening grains, and improving the strength of steel. The impact toughness of the angle steel decreases with the reduction of the final rolling temperature of the angle steel, but after adding the v value, the angle steel with the final rolling temperature of 857 and 873 ℃ can also obtain about 180J impact energy at - 40 ℃.
