Q:What foundry factories are used in the casting parts of China's major automobile manufacturers?
This is too muchYou do not have a specific list of statistics, but there are many foundries in china!Moreover, car prices are unlikely to be ordered in the local factories!
Q:How about casting parts for a year?
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:Casting parts need to be subjected to the kind of heat treatment after the weldment is finished
This is difficult to say, the key is to see the specific parts and components, the final mechanical performance requirements.For example, gray cast iron, usually graphite annealing, to heat treatment annealing, surface quenching and so on, ductile iron can be a variety of annealing, normalizing, quenching and isothermal quenching, surface treatment, chemical treatment and so on, in a word, heat treatment of steel can usually, nodular cast iron can do. Malleable cast iron and vermicular cast iron are often subjected to graphitization annealing and stress relieving annealing, while wear-resistant cast irons often undergo quenching + low temperature tempering, and so on.Welding is the case, such as bearing steel welding must be quenched + low temperature tempering, machine spindle welding (repair welding) must be quenched and tempered treatment, and so on. Of course, if it is a general weld, there is no need for heat treatment or, at most, stress relieving annealing.
Q:What method of casting does not rust? I think the sample is like oil
The surface of a general casting is easy to rust. In order to prolong the rusting period, antirust paint or antirust oil is usually sprayed. What you said should be anti rust oil.
Q:What kind of flaw detector is better for casting parts?
Casting using the detector test, you must first determine the detection process, such as the detection of surface and near surface crack defects, such as casting, recommended by CYD-3000, or CYD-5000 mobile magnetic testing machine for testing.
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:How can the casting be quenched and tempered?
Return, general castings (especially steel castings) commonly used heat treatment process is normalized and tempered. Of course there are completely by annealing or remove stress annealing...
Q:How to improve the surface roughness of casting parts?
First, the accuracy of the model should be improved; two is to change the molding technique; the three is the coating; and the worker's technical level.
Q:Why should pig iron be used in casting?
Cast iron is generally called pig iron, but casting is not merely iron casting.For example, injection molding, die casting, and so on, in fact, cast iron, cast steel, cast aluminum, plastic and so on, can be used in the form of casting processing molding
Q:How to solve casting defect casting?
Different defects, different solutions, some shortcomings, the current domestic level can not be resolved
