Q: Why does the precision casting factory not usually make iron castings?: Because it is too cheap, the design of materials is cast iron, generally do not have very high requirements.

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 are the requirements for casting steel castings?: 4 thickness, most should be placed above the.5 and try to reduce the number of.6, the sand core should be used in classification of flat surface

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: Casting parts by shot blasting, spray painting, baking after the formation of very small rust spots, how to solve ah?: The first process is very important. Shot blasting must be thorough. The solution is to wipe the surface of the paint with a release. Re shot

Q: The casting sand is going on: 3, prevention measures(1) to improve the strength of sand mold (core), especially surface strength, high temperature strength, refractoriness, compact, better coating, good core coating and parting surface coating.(2) mould and box can prevent damage;(3) the core should have clearance.

Q: What are the causes of pitting on the surface of a precision casting?: There is a bump on the mold. Or casting cooling fast.

Q: We are small castings, the need for surface treatment of shot blasting machine, about how much?: The choice of shot blasting machine, this is according to the workpiece size, yield, whether can collision, and the working time and other factors considered, while the price of different blasting machine are not the same, but the vast majority of small castings used crawler shot blasting machine, according to the comprehensive consideration of factors such as yield, size of workpiece commonly used on the market the crawler shot blasting machine has Q324, Q326, Q328, Q3210, and each time the amount of their treatment were 125KG, 200KG, 400KG, 600KG, the specific use of what types also need to be determined according to the actual situation

Q: The difference between sheet metal and casting parts: Casting parts are made by casting (followed by a variety of processing), the shape can be simple, can also be very complex, usually large parts, as a base, bed, work table, and so on, good seismic performance.

Q: ZGMn13 casting parts processing, with what knife head good?: The ZGMn13 itself is not have processing, if only the processing point, sharpening, ordinary can, if the processing area is relatively large, ZGMn13 external impact load is bigger,
