Q:What is the defect when casting s less than 0.06%?

Wax loss methodThe method can be used for the outer shell casting method and the solid casting process.First the object needed to replicate wax casting, and dry and then dipped into a ceramic containing pool, the wax replica covered with a layer of ceramic membrane, repeating the steps until the outer membrane is sufficient to support the casting process (about 1/4 inch 1/8 inch), then melting the wax mold, and cast away die. Thereafter, the mold needs to be heated many times, increasing the hardness before casting.This method has good accuracy and can be used as a foundry for high melting point metals (such as titanium). But because the price of ceramic is quite high, and the manufacture needs many heating and complex, the cost is very expensive.

Q:What's the difference between part drawings?

The internal structure of the forging is compact and high strength. It is used under relatively strict working conditions

Q:Casting problem: precision casting can process minimum pore size and wall thicknessPrecision casting. What are the advantages and disadvantages of each method? O (a _ U) O thank you

2. can be cast complex shape, and difficult to use other methods of processing castings. Casting outline size is small to several millimeters large to thousands of millimeters, wall thickness of thinnest 0.5mm, minimum hole below 1.0mm3. alloy material is not restricted: such as carbon steel, stainless steel, alloy steel, copper alloy, Aluminum Alloy and high-temperature alloy, titanium alloy and precious metals and other materials are available. For casting, forging, welding and hard alloy cutting, it is especially suitable for precision casting production method.4. high flexibility and adaptability. It can be used in mass production as well as small batch or even single productionIn summary, precision casting has the advantages of small investment, large production capacity, low production cost, simple process of complex product, investment and quick. Thus in a favorable position in the process and mode of production and other competition in the bright future.

Q:Note that is not upgraded, casting, such as the 4 sacred explosive weapons, there is a "foundry" that greatly please advice about trouble with, thank you.

Sacred equipment such as dragon knife, and Qinglong nuclear forging synthesis really Qinglong knife, and other is India's sacred nuclear synthesis, the synthesis of NPC in the NPC below the collar Deputy task, is also the lost coin that led the task, in fact this is the mid end equipment, casting is B level

Q:Where is the sword three primary casting division?

You make the task up to 10+ when will let you go to Luoyang, Yangzhou, Changan and other places, when you get off will appear in a small town in the primary can learn, to have a task,

Q:An accounting entry for depreciation in a foundry

3. A casting machine that uses sand and casting to separate sand and castings from the mold by vibration and shock. The vibration source of the shakeout machine is divided into mechanical, electromagnetic and pneumatic. 4. Shot blasting machine uses shot blasting machine to throw out high speed bullet to clean or strengthen casting surface casting equipment. The shot blasting machine also eliminates the sand, eliminates the core and clean up the casting.

Q:What is casting hot cracking? How to eliminate it? What measures are used?

2. resin sand casting process(1) to meet the requirement of filling of castings, the pouring temperature of molten steel shall be reduced as much as possible. The carbon steel of 0.19%C is poured at 1550 DEG C and poured at 1600 DEG C, and its thermal cracking resistance is almost twice as high(2) for thin wall castings, a higher casting speed should be adopted. For a cast steel, the weight is 125Kg, the wall thickness is 15mm, the casting time is 14 seconds, no hot cracking occurs, and the crack is observed until 40 seconds(3) it is an effective measure to prevent the hot cracking of cast steel parts by setting up anti cracking bars at the crack of casting(4) loosening the box in time will also help reduce hot cracking because it can reduce the shrinkage stress of the casting3. molding materials(1) reduce the amount of resin added, or modify the resin, so that the resin has a thermoplastic, so that furan resin in high temperature without coking or less coke, so as to ensure that it has a good high temperature tolerance(2) adding additives in furan resin sand, the resin sand with thermoplastic or blocked; the most serious in the contraction, wood powder, foam beads; or in the mold plastic parts into the corresponding block of concessions, improve its high temperature deformability.

Q:such as Zhejiang, Jiangsu and Anhui, 5I need to cast QT300QT500QT600, as well as HT200 and steel castings. The maximum weight of a single piece is about 2.5 tonsI hope a foundry will be able to cast the above casting grade

The revitalization of foundry which is a large enterprise of ductile iron but it mainly produces auto parts you said these are very basic is now a market economy as long as you want what others will be for your production

Q:My teacher is also the lung and liver iron casting what

He disguised as cleaners to the prison to visit teacher, but the teacher worried that the students have been implicated, sternly put him away, he later filed this sad past, always said: "my lung liver, are also cast iron!"What is the teacher think is the lung and liver stone describe the teacher unfeeling

Q:What does "hot knot" mean in casting?

According to the national standard GB/T5611-1998 definition: casting hot section, refers to the hot metal in the solidification process, the nodes in casting than the surrounding metal solidification slow or local area. Also can be said to be the final solidification place.
