Q:What is normalizing, annealing, tempering, quenching? What is the difference between forging parts and casting parts?
The aim is to make the grain fine and distribute the carbide evenly. The difference between normalizing and annealing is that normalizing cooling rate is slightly faster than annealing cooling rate, so normalizing structure is finer than annealing structure, and its mechanical properties are also improved. In addition, normalizing furnace cooling does not occupy equipment and has higher productivity. Therefore, normalizing may be used instead of annealing as much as possible. The main application areas of normalizing are as follows: for low carbon steel, after normalizing, the hardness is slightly higher than that of annealing, and the toughness is better. It can be used as the pretreatment of cutting. Used for medium carbon steel, instead of quenching and tempering, as the final heat treatment, or as an induction heating method before surface hardening. Used for tool steel, bearing steel, carburizing steel, etc., it can eliminate or restrain the formation of network carbide, so as to obtain the good organization of spheroidizing annealing. For cast steel, the microstructure can be refined and the machinability can be improved. Used for large forgings, which can be used as final heat treatment, so as to avoid larger cracking tendency during quenching.
Q:How to solve casting defect casting?
Different defects, different solutions, some shortcomings, the current domestic level can not be resolved
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:How to calculate the price of casting parts?
Cost of raw materials + electricity (fuel) costs + workers' wages + managers' wages + transport costs + raw materials burned + accessories costs + equipment maintenance depreciation costs + management fees + tax. The most convenient, the raw material market price plus 2000 yuan, plus you want profits on the line.
Q:How to cast iron and wrought iron collocation
3, if you have a file in the hand, can be used to file to see finish can also make a judgment from the file down the iron can also be seen, but this is beyond your request, it can be done in the factory. 4, if placed in the grinder grinding, see iron spark from a judge or iron wrought iron, but this is only to do in the factory. About it, may not be full, but through these methods, generally can distinguish between iron or wrought iron.
Q:How is the silicon sol precision casting part priced? What is the price per ton of casting? Such as 304 material.
I am doing this for sale, if the price is mainly based on the product structure, the difficulty of pricing. At present, if it is more formal and material guarantee manufacturers generally in 48-53 yuan /Kg (of course, products have a certain weight, such as greater than 100g), our company's current price of about 53 yuan /Kg or so. .
Q:The casting sand is going on
Dispersed sand inclusion is common on the surface and subcutaneous of steel castings, often concentrated on the outer surface of the upper box and the inner surface of the lower case, and a few of them are inside the cast steel parts.
Q:I often see Waixiejiagong drawings, casting, how to distinguish the latheman.
What you say is the difference between rough drawing and processing drawingThere must be a difference between the rough drawings and the rough ones
Q:When there is no flaw detection for large casting parts, is there any crack inside?
Cracks are considered serious levels of defects and should be repaired
Q:After reaming, the roughness can reach several levels, that is to say, the sample.Casting parts in rocker arm drilling, reaming, roughness, block. After reaming, the roughness can reach several levels, that is to say, the sample.
The finish of reaming depends on the material and the sharpness of the reamer, as well as the speed and speed of the top and bottom. Marine machine tool
