- 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 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: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:What kind of flaw detector is better for casting parts?
- If the casting is very small, can be used for fixed magnetic detection machines, of course with fixed magnetic powder the testing machine, the best first contact the manufacturers, because the fixed magnetic particle testing machine belongs to the non-standard equipment, according to the workpiece size, different shape, manufacturing daily inspection and measurement.
- Q:ZGMn13 casting parts processing, with what knife head good?
- 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:How can the casting be plated with ordinary zinc plating? The coating is too thin and requires 0.08 thickness
- Hot galvanizing doesn't seem to workThe zinc layer is 275g/ square meters of material coating is 0.019mm (mm), up to 0.08 thick.
- 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: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:As shown, how do I achieve the tightness test of this product, and achieve industrial production? Seek expert advice.
- Precise and tight sealing of the surface to which the test piece is to be tested, equipped with an airtight test instrument, and an electrical control system. You can complete automated testing equipment
- Q:Why does the surface of stainless steel casting mirror mirror ripple?
- The surface can be improved by a little more than Xiasha
