The steel plate for water conservancy and power generation is used for ring seat, motor support structure, ship lock gate and discharge chute volute of large water conservancy generating units; the representative steel grades are S500Q, S550Q, SA516, etc., which require flaw detection and have Z-direction performance requirements; the main specifications are thickness of 120mm, 180mm, 200mm, 215mm, 270mm, and the maximum width is 4400mm. The representative steel grades of wind power steel plates include Q345E, Q690E, A514 grade E alloy steel plate, etc.; the main specifications are thickness of 80mm, 100mm, 110mm, 120mm, 140mm, 160mm, 180mm, 200mm, 240mm, 260mm, 280mm, 300mm, and the width is more than 2500mm.
The basic principle of A514 grade E alloy steel plate, heat treatment of steel: put the metal workpiece in a certain medium and heat it to a suitable temperature, keep it in this temperature for a certain time, and then cool it at different speeds. Objective: to obtain the desired structure and properties by means of heating, heat preservation and cooling, so as to make the metal workpiece have the required mechanical, physical and chemical properties.
Strip steel is coiled and curved steel plate, which is different from common steel pipes and steel plates. Strip steel has obvious characteristics. First, it is thin and easy to curl, which is convenient for logistics and transportation. Second, the surface quality of A514 grade E alloy steel plate, strip steel is good, the luster is bright and it has good flexibility. Third, the strip steel is easy to process. When you need to use it, you only need to straighten the bent part and you can directly process it. Fourth, the precision is high, and the strip steel can be made of plain carbon steel, carbon structure steel, spring steel, tool steel, stainless steel, etc.
