Casting Grinding Ball Of Mining Machinery Ball Mill with High Hardness

Q: There is a little trace of polishingShock polishing is even worseElectrolysis can not be uneven, there is a slight bump: Buffing should be better, to see how your embryo, but a bit difficult

Q: What are the casting parts used to test shrinkage holes?: 2. x ray. This method can do nondestructive testing, but the cost is higher. Generally, high castings are required.

Q: our factory now produces steel castings in the use of polishing directly after spraying processing, but the powder sprayed 15But the spray powder touched off what is the reason we are not very strict requirements not only need to peel off bubbles can also, because our products are steel castings so we use steam hole sludge put on. Do not know if this spray treatment has no effect to thank friends with us!: Cast iron has not been done, if it is iron, then in the spray before going through strict pretreatment, the surface can not have a little oil dust

Q: What is the ejection angle of the die casting (Tan Gang)?: Because after the wax, wax parts will have a slight contraction, which is good for demoulding. Many moulds don't do the ejection angle

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: To distinguish from the use of materialsForging materials are mainly made of carbon steel and alloy steel of various components, followed by aluminum, magnesium, titanium, copper and their alloys. The original state of the material is rod, ingot, metal powder and liquid metal. The materials needed for casting are mostly metal, wood, fuel, molding materials and so on. In contrast, the forging parts rarely produce dust, harmful gas and noise, etc., and play a more obvious role in environmental protection. Of course, because of this, the price of forged parts on the market is higher than that of castings.

Q: How do you mark it on the drawing? Do you need to discuss it with the manufacturer?Because the casting allowance is the standard, then, after all, is the theoretical value, the actual level depends on the manufacturer, so is it necessary to ask the manufacturer?: 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 casting parts have air holes?: First, from the source, tools, raw material drying, in the process of melting into the reaction gas, another influence is pouring process, such as high temperature solidification gas dissolved too much after not excluded. The method can adjust the pouring temperature properly, control the source of gas (drying and controlling the inoculant, especially the content of magnesium), and add cooling iron to change the solidification mode. It depends on what kind of casting you are. You can't make it clear at once. And molding sand relationship is mainly water content and permeability, brush coating resin content.

Q: In the design of casting steps and precautions, for casting design, we have what experience?.: Two: the basic structure unit in the design of metal casting type and the parameters selected, usually should also pay attention to: (1) because of the metal type heat quickly, so the metal type casting minimum wall thickness should be bigger than the sand casting, metal type casting alloy minimum wall, different size of castings see table 1.1-31 thick can be selected; (2) the inner wall of the casting internal ribs and the thickness of wall thickness should be 0.6-0.7 connected, or as the inner wall (rib) cold slowly, cracks in the wall at the junction in the casting shrinkage;

Q: How to solve casting defect casting?: Prevention methodReduce the gas in the metal liquid and oxidize the slag, improve the fluidity of the metal liquidIncrease pouring temperature and pouring speed, strengthen slag collection, slag block or bottom pouring bag, teapot ladle pouring, can not cut off when pouring, prevent the slag from blocking the nozzle, and cause the casting to breakIncrease the sprue and sprue height, increase the runner section area and the sprue number, and improve the filling speed and the metal hydrostatic headImprove the casting design and increase the thickness of the thin-wall part of the castingChange the pouring position and pouring system, the casting thin wall plane is located at the top and away from the gate, to prevent the filling of liquid metal splashing, eddy current, avoid metal stream in the casting thin sections or core support, cold iron, insert the confluence, when necessary, take horizontal vertical pouring cold or inclined castingIncrease the permeability of core and sand, strengthen the exhaust of mould, and the quantity of air outlet and riser should be enoughChange the size and location of the core, the inner cold iron, the core support, the internal cold iron, the insert should be no rust, no oil pollutionCheck the type, tight box, press the operation of iron is safe, to prevent running fire
