Q:What is the difference between forging parts and casting parts?
No, it's called die castingDifference: the die casting parts are simple in structure and large in batch sizeCasting: the use of a wide range of structures without restrictions
Q:Casting parts need to be subjected to the kind of heat treatment after the weldment is finished
Annealing is needed to eliminate stress and refine grain
Q:What is normalizing, annealing, tempering, quenching? What is the difference between forging parts and casting parts?
According to the requirements of the workpiece annealing, there are many kinds of annealing process specifications, such as full annealing, spheroidizing annealing and stress relieving annealing. Steel the steel quenching is heated to the critical temperature Ac3 (hyposteel) or Ac1 (hypereutectoid steel) above a certain temperature, holding time, so that all or part of 1 Austenitic, then the cooling rate is greater than the critical cooling rate of fast cooling to below Ms (or near Ms isothermal) of martensite the body (or bainite transformation) heat treatment process. Aluminum alloys, copper alloys, titanium alloys, tempered glass and other materials are usually treated by solid solution or heat treatment with rapid cooling process. Tempering is a heat treatment process where the workpiece is hardened and heated to a temperature below AC1, which remains cool for a certain period of time and then cools to room temperature. Tempering generally followed by quenching, the purpose is: (a) to eliminate the residual stress caused by quenching, prevent deformation and cracking; (b) hardness, strength, plasticity and toughness of workpiece is adjusted, to use performance requirements; (c) the size of organization and stability, ensure the accuracy improvement; (D) and to improve the processing performance. Tempering is therefore the last important step in obtaining the desired properties of the workpiece. According to the tempering temperature range, tempering can be divided into low temperature tempering, medium temperature tempering and high temperature tempering. This answer is recommended by the questioner
Q:The cause of fracture and why there is no toughness
This question is too broad, see what the casting casting Oh in order to reduce the wayward cast steel, ductile iron, gray iron and white iron, you can choose the material according to their own requirements.
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:When the blank is a casting, the margin is evenly distributed, how should rough machining? Twenty
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:Why do casting parts have air holes?
First, from the source, tools, raw material drying, in the process of melting into the reaction gas, another influence is pouring process, such as high temperature solidification gas dissolved too much after not excluded. The method can adjust the pouring temperature properly, control the source of gas (drying and controlling the inoculant, especially the content of magnesium), and add cooling iron to change the solidification mode. It depends on what kind of casting you are. You can't make it clear at once. And molding sand relationship is mainly water content and permeability, brush coating resin content.
Q:Tolerance standard for casting parts
The tolerance of a specific size can be obtained from the tolerance grade and nominal size of the casting.
Q:What is the difference between the casting drawing and the car work drawing?
The technical condition or the material column in the title column will tell whether it is a casting drawing or not. However, the need for casting drawings, and some also through machining (car, milling, etc.), this should be part of the process drawings, process drawings are described
Q:What is the casting material?
Gray iron, carbon steel, low alloy steel, ductile iron, stainless steel, Aluminum Alloy can all be cast out
