- Q: What is normalizing, annealing, tempering, quenching? What is the difference between forging parts and casting parts?
- For the nodular cast iron, the hardness, strength and wear resistance are improved, such as used in the manufacture of automobile, tractor, diesel engine crankshaft, connecting rod and other important parts. A normalizing and hypereutectoid ball annealing before, can eliminate the mesh two cementite spheroidizing annealing, to ensure that all spheres of cementite. Annealing is a metal heat treatment process, which means the metal is slowly heated to a certain temperature, sufficient for a long time, and then cooled at an appropriate speed. The purpose is to reduce hardness, improve machinability, eliminate residual stress, stabilize size, reduce deformation and crack tendency, refine grain, adjust microstructure and eliminate tissue defects. Its purpose: (1) reduce hardness and improve machinability; (2) eliminate residual stress, stabilize size, reduce deformation and crack tendency; (3) refine grain, adjust microstructure and eliminate tissue defects. In production, annealing process is widely used.
- Q: Explain the heat treatment effect of casting parts, forging parts and welding parts
- The three methods of metal processing have one thing in common. They are hot working, which are different in temperature and range of processing. Ductile cast iron is widely used because of its brittleness and poor impact. Heat treatment of cast iron usually adopts the annealing process, reduce the casting effect: 1 because of the internal stress caused by the thermal expansion and contraction, reduce the deformation after machining, decrease surface hardness, improve machining conditions;
- 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: Selection of hydraulic press is the casting parts and steel plate welding, how to choose?
- Casting parts in one shape, the overall processing in this regard than steel plate welding better. The same price is much more expensive than steel. Large hydraulic presses seldom have casting parts.
- Q: Casting parts have poor surface finish. What sand is used to make them?
- Manual coal dust, clay sand is a little worse. Mechanical styling is not bad either.
- 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: What kind of flaw detector is better for casting parts?
- If the casting is very small, can be used for fixed magnetic detection machines, of course with fixed magnetic powder the testing machine, the best first contact the manufacturers, because the fixed magnetic particle testing machine belongs to the non-standard equipment, according to the workpiece size, different shape, manufacturing daily inspection and measurement.
- 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. Roughness mainly depends on the surface roughness on the surface of the sand.
- Q: Can the casting part be phosphating with the phosphating solution of the pickling board?
- If it is Phosphating for painting, it is not necessary, because the surface of the casting is rough and can be firmly bonded with the paint film.
- Q: How can the casting be free of trachoma?
- 3, the gate is not facing sand core, flush sand core, will cause trachoma.
