- Q: It is generally said that cast iron is re smelted by pig iron. My question is..:1 pig iron for melting iron, is directly cast into products (such as bed cover, etc.); or that is just the first pig iron smelting iron casting, such as to cover, bed and other products, will once again cast iron melt to casting?2, there are many castings to the engine. Are these castings made by the engine manufacturer themselves or bought by others?There is no need to answer all. Thank you！！！
- The molten iron (molten iron, scrap steel, scrap casting, iron alloy) is melted into cast iron by means of an electric furnace or cupola, and is poured into a casting.
- Q: In theory, which is more expensive, forging parts or casting parts?
- The structure of the casting is relatively flexible in design, and the modeling is easy to realize.
- Q: How can the casting be quenched and tempered?
- Cast steel annealing or normalizing parts in strength and toughness is insufficient, can be used in quenching and tempering treatment. It is mainly used for gear, gear and other parts of the cast steel. The conditioning has two kinds: one kind is cast directly after quenching and tempering, with warm water (40---50 degrees) intermittent cooling, suitable for ZG270---500, ZG310----570 and other castings.
- Q: How to distinguish the forging parts and casting parts accurately
- Distinguish from performance:The processing performance of forged parts is higher than that of the same material. The forging parts are compact and have good mechanical properties, but the casting parts may have sand holes, holes, shrinkage holes and other defects, and their mechanical properties are inferior to those of forgings. At the same time, forging processing can ensure the continuity of the metal fibrous tissue, fibrous tissue to forging and forging shape consistency, metal streamline integrity, can ensure the parts with mechanical properties and long service life good.
- Q: What is the casting material?
- Gray iron, carbon steel, low alloy steel, ductile iron, stainless steel, Aluminum Alloy can all be cast out
- Q: Would you please tell me how to use casting parts for a year?The cast of an aircraft wing needs to be put aside for a year before it breaks;Does anyone know why?
- 2, heat aging (artificial aging), also known as stress annealing, is to heat the casting to 550-650 degrees, insulation 2 - 4h, with the furnace cooling to 150 - 200T, and then baked.
- Q: How can the casting be plated with ordinary zinc plating? The coating is too thin and requires 0.08 thickness
- Hot galvanizingGenerally 0.06 mm or more
- Q: When there is no flaw detection for large casting parts, is there any crack inside?
- According to the industry standards, within the scope of the standard requirements to determine whether the product is qualified
- Q: When the blank is a casting, the margin is evenly distributed, how should rough machining?Please help friends from mechanical classes.There is another problem: in the NC milling plane contour machining, when the rough margin is large, how to deal with.Who can help in time, add 20 reward. Urgently!!
- Problem one,1, according to drawings, castings, material requirements and machine power, choose the right diameter of roughing tools, and can process this material blade type.2, according to the actual size of the casting blank, calculate the number and path of the knife, pay attention to small cutting depth, large feed, cutting width, to ensure that the tool diameter 80 - 90%, the amount of not full knife cutting, this tool and machine tool damage.Question two,If they can not change the casting blank allowance under the condition that the quantity large diameter cutter, such as milling cutter main angle 7560 degrees can give reasonable processing parameters, the same cutting depth should not be too large, because in the same machine power, tool diameter increases, cutting depth will need smaller.
- Q: Is 316 casting better than 304 casting?
- The degree of difficulty in the process of casting depends mainly on the structure, precision requirements, and hardness of the casting. It is comprehensive. There is no simple comparison of the material to determine the degree of difficulty in processing
