Q:ZGMn13 casting parts processing, with what knife head good?
its surface wear resistance is high; the two is with the gradual wear of surface hardening, the hardening layer is continuously formed new if you have suggestions, processing, plasma cutting or flame cutting try
Q:Which surface is coarser for cast iron or cast steel castings? Why?
The surface of the steel is more rough, because the coating sand cast steel cast iron particles compared with graphite coating degree, the other one is to get a better air permeability and collapsibility of sand, the compaction degree is smaller than iron.
Q:Cast iron, casting parts 5
1, qualified enterprises will directly iron ore into molten iron, and then poured into the mold, such a good product performance. I work in the cast iron industry, which I can tell you for sure.2, this, like the Great Wall Motor Company has its own parts production department, as well as the corresponding mold center, so it will be their own casting. If the manufacturer does not have these departments, they can only place orders for others to do.
Q:What are the general technical requirements for casting parts?
No matter what kind of material casting, there are the following major requirements:Material requirements. Mainly hardness, tensile strength, elongation, impact toughness.Two, dimensional accuracy and shape accuracy. Different castings have different requirements. Different sizes and geometric tolerances and different tolerances are adopted.Three, according to the use requirements, the casting of other defects, acceptance requirements. Such as holes, sand holes, shrinkage, slag, sand, crack.........Four. Requirements for defect repair.
Q:How can the casting be free of trachoma?
Measures for the prevention of trachoma in castings:1, sand compaction to high, paint two times;
Q:Tolerance standard for casting parts
Usually manual molding optional CT11 class, ordinary machine modeling optional CT10 class, high pressure molding should reach CT9 level. The tolerances on the wall thickness of the casting are comparable to those of other dimensions of the same casting.
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:What's the effect of casting copper?
Riga. Copper is copper components, promote the graphitization of the copper element, make dense tissue, and to refine and improve the uniform distribution of graphite, which can reduce the chilling tendency of the cast iron, but also can promote the formation of pearlite, has a favorable effect on the section sensitivity. Copper has the tendency to strengthen cast iron, ferrite and pearlite, so it can increase the strength of cast iron. The tensile strength and bending strength of cast iron almost increase with the amount of copper in it, especially in low carbon cast iron.
Q:How to judge whether the casting is qualified?
For example, the castings shall be in accordance with the requirements of the second types of castings in the technical requirements for aluminum alloy castings of GB/T9438-1999;
Q:What are the casting parts tested?
The surface brightness, appearance, size, chemical composition, weight, material, surface defects, internal defects, seals need to be checked, leakage, etc.
