4. Packing Methods of High Chrome Grinding Media Ball with High Hardness & Good Wear Resistance & High Toughness & No mal-roundness
- Q:It is generally said that cast iron is re smelted by pig iron. My question is..:1 pig iron for melting iron, is directly cast into products (such as bed cover, etc.); or that is just the first pig iron smelting iron casting, such as to cover, bed and other products, will once again cast iron melt to casting?2, there are many castings to the engine. Are these castings made by the engine manufacturer themselves or bought by others?There is no need to answer all. Thank you！！！
- 1, qualified enterprises will directly iron ore into molten iron, and then poured into the mold, such a good product performance. I work in the cast iron industry, which I can tell you for sure.2, this, like the Great Wall Motor Company has its own parts production department, as well as the corresponding mold center, so it will be their own casting. If the manufacturer does not have these departments, they can only place orders for others to do.
- Q:What is the reason for 304 stainless steel precision casting parts to be changed?
- 304 stainless steel is easier to change than ordinary steel. Because the 304 heat conductivity is lower than that of the low doped steel, the temperature is even more uneven, and 20% of the non ferrous elements also make the distribution of internal and external elements more uneven, hard and soft inside. Each of these two produces greater internal stresses, resulting in a variant.
- Q:The difference between cement sand castings, resin sand castings and vacuum casting parts
- Our country or international, in all casting production in 60 ~ 70% by sand casting is produced, of which about 70% is used in the production of clay sand. The main reason is that the cost of sand casting is low compared with other casting method, simple production process and short production cycle. So as the car engine cylinder body the cylinder head, crankshaft castings are produced using clay wet sand molding process. When the wet type can not meet the requirement to consider the use of clay sand table dry sand, dry sand mold or other sand.
- Q:How to improve the surface roughness of casting parts?
- One is to improve the accuracy of the model; the two is to improve the molding sand mesh. How much is the other relationship?.
- Q:What kind of flaw detector is better for casting parts?
- If you want to detect internal defects, you can use ultrasonic flaw detector, ray flaw detector can also, but the ray of the safety protection level is too high, not recommended priorityMacro Xu flaw detector answered, such as the magnetic particle inspection machine has the demand can contact us, Baidu "macro Xu flaw detection""
- Q:Younger brother is to do casting valve, precision casting parts, the valve internal sand serious, but the appearance is very standard, this is why, for God answers, thank you!
- Increase the refractoriness and looseness of core sand
- Q:In the design of casting steps and precautions, for casting design, we have what experience?.
- (3) to prevent generating white grey cast iron, in addition to taking measures from the process, must make the wall thickness is not too thin (some sources indicate that the corner wall thickness above 15mm, metal type casting must be in the corner, for Aluminum Alloy, magnesium alloy casting casting casting Create fillet should not be less than 3-4m, for casting round cast iron, copper alloy mould casting can see table 1.1-32 selection; (5) because of the metal and the core without let, for the convenience of the casting is taken out and the draw out type, slope casting casting should be suitably large than sand casting metal casting. General 30%-50%, it should be pointed out that in addition to the height of the slope of casting size and alloy type, wall, is also related to the casting surface position, where the cooling and contraction and metal surface of casting surface can be designed from the tendency of small inclination, while casting shrinkage tend to be pressed on the surface of metal castings the type should be given greater inclination, all kinds of metal type alloy casting casting casting.
- Q:What are the casting parts used to test shrinkage holes?
- 1. anatomy. It is easy to slack off by sawing and machining.
- Q:Is the cast steel a casting part?
- Yes, molten steel is poured into the mold and cooled to become a casting. Can also cast iron, cast aluminum, plastic casting.
- Q:Why does the surface of stainless steel casting mirror mirror ripple?
- The surface can be improved by a little more than Xiasha
