Q:Explain the heat treatment effect of casting parts, forging parts and welding parts

2 improve the crystal structure, enhance the formation and stability of spherical carbon crystal;Forgings are generally stress bearing members, and most of them are made of high strength medium carbon steel (alloy), which is formed by forging and fine crystalline. After the shell is annealed or quenched and tempered, the mechanical properties of the shell are more superior, and it has better strength and better elasticity;Welding materials.

Q:ZGMn13 casting parts processing, with what knife head good?

The ZGMn13 itself is not have processing, if only the processing point, sharpening, ordinary can, if the processing area is relatively large, ZGMn13 external impact load is bigger, its surface wear resistance is high; the two is with the gradual wear of surface hardening, the hardening layer is continuously formed new if you have suggestions, processing, plasma cutting or flame cutting try

Q:What are the requirements for casting steel castings?

1, high quality requirements of the surface or the main processing surface should be placed below.

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:What is the casting material?

Gray iron, carbon steel, low alloy steel, ductile iron, stainless steel, Aluminum Alloy can all be cast out

Q:What is the difference between casting and stamping parts?

Separation process is also called blanking, the purpose is to make the stamping parts along a certain contour line from the sheet metal separation, at the same time guarantee the quality requirements of the separation section. Stamping is a highly efficient production methods, the use of compound die, especially the multi station progressive die stamping process can be completed in a multi machine, realized by belt uncoiling, leveling, punching, forming and finishing automatic production. High production efficiency, good working conditions, low production costs, can produce hundreds of parts per minute.

Q:How is the silicon sol precision casting part priced? What is the price per ton of casting? Such as 304 material.

The material is usually steel material price plus the cost (per ton of 2.5-3 million, plus profit).In the Yangtze River Delta region, generally 304 casting price of about 5-5.5 million / ton.The price will be higher if the parts are complex, or a piece weighs less than 100 grams.

Q:What are the effects of stiffeners on castings, or on welded parts (for 2 tons or less), casting or weldments on stiffeners?

Please consider the following points:1, batch: if the product batch is very large, casting will certainly have advantages, cost sharing will be very low. If less, it is recommended to use weldments.2. Reinforcement structure: if the structure is relatively simple, it is recommended to use welded parts, complex, preferably casting.

Q:Selection of hydraulic press is the casting parts and steel plate welding, how to choose?

Casting parts in one shape, the overall processing in this regard than steel plate welding better. The same price is much more expensive than steel. Large hydraulic presses seldom have casting parts.

Q:There is a little trace of polishingShock polishing is even worseElectrolysis can not be uneven, there is a slight bump

Use the vibrator to polish the material: the high aluminum porcelain 4cm (with a polishing agent that has an automatic mending function), you go find this polish,
