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: What are the factors affecting the machining process of the casting material and structure?
Medium carbon steel begins, and the casting can not be punched and tapped directlyStainless steel, ordinary grade (Fe based alloy element content, less) can not do heat treatment. But processing small holes or tapping to heat treatment (solution. In practice, the annealing treatment can also be). There are a lot of stainless steel matrix is not to say, for example, nickel, cobalt and tungsten. And so on.
Q: What's the effect of casting copper?
Riga. Copper is copper components, promote the graphitization of the copper element, make dense tissue, and to refine and improve the uniform distribution of graphite, which can reduce the chilling tendency of the cast iron, but also can promote the formation of pearlite, has a favorable effect on the section sensitivity. Copper has the tendency to strengthen cast iron, ferrite and pearlite, so it can increase the strength of cast iron. The tensile strength and bending strength of cast iron almost increase with the amount of copper in it, especially in low carbon cast iron.
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!
You oily sludge!Is not the general market on the soil?If it isPlease use two groups of chemicals to reinforce the soilOr suggest your company?Do the putty or paint film after doingThat's better
Q: Casting parts need to be subjected to the kind of heat treatment after the weldment is finished
This is difficult to say, the key is to see the specific parts and components, the final mechanical performance requirements.For example, gray cast iron, usually graphite annealing, to heat treatment annealing, surface quenching and so on, ductile iron can be a variety of annealing, normalizing, quenching and isothermal quenching, surface treatment, chemical treatment and so on, in a word, heat treatment of steel can usually, nodular cast iron can do. Malleable cast iron and vermicular cast iron are often subjected to graphitization annealing and stress relieving annealing, while wear-resistant cast irons often undergo quenching + low temperature tempering, and so on.Welding is the case, such as bearing steel welding must be quenched + low temperature tempering, machine spindle welding (repair welding) must be quenched and tempered treatment, and so on. Of course, if it is a general weld, there is no need for heat treatment or, at most, stress relieving annealing.
Q: How to get rid of casting sand inside casting parts?
Are you saying that in the sand casting cavity? We use the manual blast, he is like a pipe will be automatic shot out of the grit, into the casting cavity, to remove the internal cavity in the purpose of casting sand!
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 parts of the threaded hole is casting, casting the hole directly, and then tapping or casting, and then punch 10When the casting is ready, punch it again before tapping it Is the hole casting good or is it punched and tapped on the drilling machine after casting?
There are several casesThe first hole with a diameter of less than 4MM is generally not done, or as a hole location only for a period of less than 10MM.Second for the big hole, some of the reasons for the holding force, we must increase the slope, direct tapping is unlikely, so it still needs post-processingThird for products with high tightness requirements, some cores need to be made even if they are very small, so they can be tapped directlyFourth, some due to technical requirements, regardless of the size of each other's requirements must be made, there is no wayThe above methods are common, and they will encounter many small problems in actual production.
Q: Cause of choking of casting parts
The reason is not in the coated sand, see coating gas evolution, the best use of zircon powder coating (low gas evolution), there is a mold according to a vent needle, this depends on your way is flat or vertical pouring pouring pouring, if vertical pouring, venting pin on the die, and the big piece how could the plane, pouring water flat, a breath, a taboo ah!
Q: What's the cause of the choking of the casting?,
3. when casting the environment is humid, sand mold has not removed the moisture, when the casting, the moisture instantaneous transforms into the steam, causes the blowhole
