Q:What are the requirements for casting steel castings?
1, high quality requirements of the surface or the main processing surface should be placed below.
Q:What reason is the bronze statue choking fire?
The casting process in boiling phenomenon, is the setting of the exhaust hole positioner position or number is not reasonable, the air cavity can not be discharged, overwhelmed by a material inlet, reflux, change mould, sincerely help you look forward to adopt,
Q:How to judge whether the casting is qualified?
According to different casting process and parts materials, each has relevant standards, can be found online;
Q:What are the effects of stiffeners on castings, or on welded parts (for 2 tons or less), casting or weldments on stiffeners?
3, weight: if reinforcement in products, casting weight is generally greater than the welding parts (the internal organizational structure and mode of production determines the mechanical properties of materials, so it determines the weight of the product), considering the cost of transportation, certain priority structure.
Q:How much is the casting allowance in the design of the casting machine and the drawing?
Casting parts do not need to provide drawings of casting blank, the casting factory according to your drawings in the required surface will be sufficient allowance, and the rest of the size according to the mechanical design manual and the casting manual can be found. The general foundry casting technology division will mark put shrinkage and the allowance of the map in your chart (usually with the red pen) for the production of wood or other material wood workers die drawings.
Q:Why do cheap cars like stamping parts instead of casting parts?
Separation process is also called blanking, the purpose is to make the stamping parts along a certain contour line from the sheet metal separation, at the same time guarantee the quality requirements of the separation section. Stamping is a highly efficient production methods, the use of compound die, especially the multi station progressive die stamping process can be completed in a multi machine, realized by belt uncoiling, leveling, punching, forming and finishing automatic production. High production efficiency, good working conditions, low production costs, can produce hundreds of parts per minute. The purpose of forming processes is to allow the sheet to undergo plastic deformation without breaking the billet and to make the desired shape and size. In actual production, a variety of processes are often applied to a workpiece. Blanking, bending, shearing, drawing, bulging, spinning, and straightening are the main types of stamping machines.
Q:How do casting parts remove stress?
Annealing treatment, according to different casting annealing treatment, eliminate thermal stress, if need to restore hardness or increase hardness, and then quenching treatment
Q:How to distinguish the forging parts and casting parts accurately
Distinguishing between forging and casting can be done from the following points:From the principle of distinguishingForging processing of machining by hammer or press and other equipment for forging parts produced in hot state, casting processing of metals into liquid, pouring into the cavity with a specific shape, produced by machining parts after cooling solidification. Simply say that forging is the metal soft pinch molding, and casting the metal into thin cooling solidification.
Q:The casting sand is going on
2, causes(1) sand mold (core) strength is not high, when the box a little reason will fall off.(2) the strength of sand mould (core) is not high, it can not stand the erosion of molten steel.(3) box sand mould (core) crush.(4) high strength under high temperature, warpage, deformation and protuberance into the cast steel under the action of high temperature molten steel.(5) the floating sand in the air hole of the sand mold falls, especially when the floating sand falls in the casting, and the floating sand on the surface of the sand mold is easy to fall through the air vent.(6) when the box is closed, the surface of the mold cavity and the surface of the sand core are not cleaned, and the sand (core) surface has floating sand and so on.
Q:What are the casting parts processing engineering?
According to the classification of process methods, sand casting and special casting.
CGBM established in 1995, the largest and most specialized casting and forged products supplier in China. Min products are grinding media balls, grinding rods, cylpebs, mill liners and steel flanges, with specifications all reaching international standards and annual production capacity is over 150,000tons.
