- Q: There is a little trace of polishingShock polishing is even worseElectrolysis can not be uneven, there is a slight bump
- German winter three step mirror polishing 2013 new processYou can free proofing!
- Q: Why does the precision casting factory not usually make iron castings?
- The so-called precision parts is the size, roughness requirements of the piece. Cast iron parts generally do not reach the accuracy.
- Q: What are the factors affecting the machining process of the casting material and structure?
- The impact on the machining is obvious, it should be the material and heat treatment of the castingCarbon steel parts should be treated by heat treatment (annealing) without special conditions. It can effectively prevent the uneven hardness and hard points. It is easy to turn.
- Q: The casting defects of pores, trachoma how to repair?
- Metal repair can be used to fill the repair. Airhole 2mm following LT102 recommend the use of liquid metal repairing agent.
- 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 method of casting does not rust? I think the sample is like oil
- The surface of a general casting is easy to rust. In order to prolong the rusting period, antirust paint or antirust oil is usually sprayed. What you said should be anti rust oil.
- 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.
- Q: As shown, how do I achieve the tightness test of this product, and achieve industrial production? Seek expert advice.
- Precise and tight sealing of the surface to which the test piece is to be tested, equipped with an airtight test instrument, and an electrical control system. You can complete automated testing equipment
- 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: 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
