- Q: The casting defects of pores, trachoma how to repair?
- Airhole above 2mm recommended LT101 casting defect repair agent. If repair quality requirements, high availability LT111 iron repair agent, LT112 steel repair agent, LT113 aluminum repair agent, LT114 copper repair agent.
- Q: Domestic large steel castings factory which is better, recommend!
- At least spend money on research and development, then the quality should be all right.
- Q: What kind of casting process is used for cast iron parts? And what are the cast steel parts adopted?
- Corundum sand: the main mineral composition is corundum alpha -Al2O3, used for investment casting, ceramic mold casting shell materials. The olivine sand: the main mineral composition of olivine (MgFe) 2SiO4, used in cast iron, non-ferrous alloy castings and high manganese steel casting molding sand and the core sand. Silica resources in nature resources, but suitable for casting with high SiO2 content of natural silica sand is not too much. Since 1951, China has carried out a general survey of the casting sand resources in the territory, but mainly limited to the main traffic lines and major industrial cities. Survey results show that Chinese can be used for natural silica sand casting is very rich in resources, a wide range of distribution. Inner Mongolia Zhelimumeng, natural silica sand reserves amounted to hundreds of millions of tons, the particle shape close to the circular, the content of SiO2 is about 90%. Fujian, Jinjiang Dongshan sea sand, the content of SiO2 is 94 to 98%, with a low volume of mud, are good natural silica sand. Are Duchang, Yongxiu Jiangxi County Xingzi, a large number of Quaternary lacustrine deposition of silica sand, the content of SiO2 is about 90%, low iron content, alkaline oxide less, uniform size, is a good lake sand. Guangzhou, Hunan and other places have abundant easily broken weathered sandstone, processing artificial silica sand, the content of SiO2 in more than 96%, can be used for the production of steel castings. Jiangsu Nanjing red sand, sandy mud pure, moderate, strong permeability, good viscosity, high silica content, less water, fine particles, pulls out the casting is smooth, stable quality, can be made of cast iron and non-ferrous metal parts of the sand and core sand
- Q: How can the casting be quenched and tempered?
- Cast steel annealing or normalizing parts in strength and toughness is insufficient, can be used in quenching and tempering treatment. It is mainly used for gear, gear and other parts of the cast steel. The conditioning has two kinds: one kind is cast directly after quenching and tempering, with warm water (40---50 degrees) intermittent cooling, suitable for ZG270---500, ZG310----570 and other castings.
- Q: Would you please tell me how to use casting parts for a year?The cast of an aircraft wing needs to be put aside for a year before it breaks;Does anyone know why?
- 2, heat aging (artificial aging), also known as stress annealing, is to heat the casting to 550-650 degrees, insulation 2 - 4h, with the furnace cooling to 150 - 200T, and then baked.
- Q: Where is the precision casting factory?
- The National Precision Casting Factory is generally distributed in Shandong, Ji'nan, Jiangsu, Wuxi, Changzhou, Zhejiang, Guangdong, Panyu, Dongguan.The above are only the main distribution, many of Shandong are made supercharger, and Guangdong to jewelry industry based.
- Q: What foundry factories are used in the casting parts of China's major automobile manufacturers?
- This is too muchYou do not have a specific list of statistics, but there are many foundries in china!Moreover, car prices are unlikely to be ordered in the local factories!
- Q: What do you mean by "proofing" in the casting? Do you charge for the proofing?
- Die die must charge, wood cheap, expensive aluminum mold
- 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.
- Q: Younger brother is to do casting valve, precision casting parts, the valve internal sand serious, but the appearance is very standard, this is why, for God answers, thank you!
- If is casting, internal shell mold may be not completely dry, strength is not enough, resulting in shell mold collapse into molten steel.It is also possible that the refractory is not refractory enough.
