Q:The cause of fracture and why there is no toughness
This question is too broad, see what the casting casting Oh in order to reduce the wayward cast steel, ductile iron, gray iron and white iron, you can choose the material according to their own requirements.
Q:Why do casting parts have air holes?
There are many reasons for casting porosity, mainly due to:1. smelting process is unreasonable, metal liquid absorbs more gas;2. the gas in the mold invades the metal liquid;3. from the mold is more water brush, core dry;4. the casting has poor ventilation;5. ladle tools are not dry.Wait。
Q:The difference between cement sand castings, resin sand castings and vacuum casting parts
The clay wet sand castings casting weight from a few kilograms until tens of kilograms, but the clay dry type of casting production can be weighed dozens of tons.For medium and large castings, cast iron, cast steel can be self hardening sand with resin can be water glass sand production, can obtain the precise size, smooth surface castings, but casting precision, surface roughness, density and microstructure, mechanical properties and material cost of sand casting production is often poor, so when the higher performance requirements of castings, should adopt other casting methods, such as casting (lost wax casting), die casting, low pressure casting.
Q:Is 316 casting better than 304 casting?
It is comprehensive. There is no simple comparison of the material to determine the degree of difficulty in processing
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,
Q:How much is the amount of electrophoretic paint per square meter used in the casting?
In general, when the final thickness of 15-20 microns, cathode electrophoresis paint can be coated per kilogram of 6-8 square meters, the current general cathode electrophoresis paint for the price of 22 yuan / kg, so the cathodic electrophoresis electrophoresis paint cost at 4 yuan / square meters.
Q:What kind of casting process is used for cast iron parts? And what are the cast steel parts adopted?
The types and uses of foundry sand according to the mineral composition of different silica sand and non siliceous sand is divided into two categories. The main mineral composition of silica SiO2.: natural silica sand used for non-ferrous metal casting, cast iron and steel castings in small sand and core sand. The selection of natural silica sand: used in organic matter as the binder of various sand and core sand. The artificial sand for sand and core sand castings. Non siliceous sand and non siliceous sand have many kinds and different uses. Limestone sand: crushed by limestone, the main mineral composition is CaCO3, used for casting sand and core sand. Zirconium sand: the main mineral composition is ZrO2 SiO2, used for large steel castings and alloy steel pieces of core sand or sand surface sand, or powder used as coating. Magnesia: the main mineral composition is MGO, used for high manganese steel casting surface sand, core sand, and its powder can be used as coating. Chromite ore: the main mineral composition is chromite FeO. Cr2O3, used for large or special casting steel surface sand, core sand, its powder can be used as coating.
Q:The casting sand is going on
3, prevention measures(1) to improve the strength of sand mold (core), especially surface strength, high temperature strength, refractoriness, compact, better coating, good core coating and parting surface coating.(2) mould and box can prevent damage;(3) the core should have clearance.
Q:General aluminum alloy die casting or casting box and other parts,
Single for this problem, the direct casting out of course good. But many times because of the limitations of the process, so we choose the post-processing hole
Q:What are the effects of stiffeners on castings, or on welded parts (for 2 tons or less), casting or weldments on stiffeners?
4, the performance requirements of the steel: whether castings or welding parts, there may be quality defects, but the casting will generally be worse than the weldment.You should be able to make a choice in the end.
