Q:What reason is the bronze statue choking fire?
The casting process in boiling phenomenon, is the setting of the exhaust hole positioner position or number is not reasonable, the air cavity can not be discharged, overwhelmed by a material inlet, reflux, change mould, sincerely help you look forward to adopt,
Q:How to judge whether the casting is qualified?
According to different casting process and parts materials, each has relevant standards, can be found online;
Q:What are the general technical requirements for casting parts?
According to the national standard GB/T 9438, there are 8 aspects: 1. chemical composition; 2. delivery status; 3. mechanical properties; 4. dimensional tolerances; 5. weight tolerances; 6. appearance quality; 7. internal quality; 8. casting salvage.
Q:What is the ejection angle of the die casting (Tan Gang)?
Especially deep hole, and customers to discuss, generally take 0.3-1 degrees is enough
Q:What kind of casting process is used for cast iron parts? And what are the cast steel parts adopted?
The main content of red sand table (Institute of soil science, China) silica 79.4%. three 1.48%. three 10.55%. two aluminum oxide iron oxide, calcium oxide 0.85%. Magnesium Oxide 0.52%. 1440. refractory mud 3.06% LOI 1.98% red sand with high silicon content, permeability is strong, durable, high refractoriness, good angle, low moisture content, less mud the casting finish is high, the basic requirements of sand should meet the following requirements: Casting of high purity and cleanliness, with silica sand as an example, iron sand SiO2 content of more than 90%, the big steel casting requests the SiO2 content of more than 97%; the high refractoriness and thermal stability; the suitable particle the shape and particle composition; it is not easy to be wetted by the liquid metal; cheap. The particle shape and composition of casting sand particle shape and particle composition permeability properties such as mobility, sand compaction, permeability, strength and resistance to liquid metal effects, is an important indicator of the quality of casting sand.
Q:Where is the difference in performance between the rolled and cast parts of the same part?
uch as: automobile transmission shaft adopts mechanical rolling machine with good performance, gray cast iron can play seismic effect effectively, with good thermal conductivity of radiator graphite in gray cast iron, the aircraft engine turbine blade by casting directional solidification casting and Dan Jingzhu.Do everything we can to make the best use of it, the advantages and disadvantages of rolling and casting, and you'll find it yourself, Baidu, depending on how you use it
Q:How about casting parts for a year?
There are various casting stresses after casting, which can be divided into two kinds: thermal stress and shrinkage stress. In a long time placed in the atmosphere, called aging treatment.Aging treatment is an effective measure to eliminate casting stress. Aging is divided into natural aging, thermal aging and resonance aging.1, the so-called natural aging, the casting is placed in the open field for more than half a year, so that the internal stress relief.
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: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:Heat treatment process and purpose of casting parts
Methods: artificial aging or natural aging (also called normalization) treatment.Artificial aging: heating to 2-3 Baidu, it is best to apply mechanical vibration, and maintain a period of time.
