Selection of round steel usage (for forgings)
Thread Content
I need to manufacture one component made of corrosion-resistant alloy steel. The dimensions of the raw forging required are a diameter of 500 mm and a length of 200 mm. How much round steel with a diameter of 100 mm do I need to purchase in order to forge a forging of these dimensions? What is a suitable forging ratio for this process? Thank you
Based on the law of conservation of mass, plus a little loss, it’s basically done
May I ask how this 5 meters was calculated?
5m is determined using the forging ratio, which is the ratio of height before forging to height after forging; it’s ideal for this ratio to be a little over 5 meters, as there are inevitably some losses
It has little to do with forging. 1. Basis for material calculation: The principle of constant volume, combined with the machining allowance reserved for the forging blank, makes it easy to carry out the calculation. 2. Calculation method: Appropriate machining allowances are added to both the diameter and length; the ratio of lengths is equal to the inverse of the square of the diameter – thus, the calculation is straightforward. 3. There is a concept related to the forging ratio, but it isn’t closely related to this. It is a concept that indicates the degree of deformation that a material can withstand; excessive values may lead to cracking or bending. The forging of the shaft should be free forging, so it doesn’t need to be considered.
Round steel for forging is steel that is produced by smelting pig iron. It is an alloy whose main components are iron and carbon. In addition to iron and carbon, steel also contains small amounts of impurities such as silicon, manganese, phosphorus, and sulfur. Among them, phosphorus and sulfur are harmful impurities in steel. Furthermore, other special chemical elements such as chromium, nickel, tungsten, molybdenum, aluminum, titanium, etc., can also be added to improve the quality of the steel.
