As a   Grey Iron Casting Company , share with you. Enhancement method Methods to increase the tensile strength of gray iron castings: 1. A small amount of carbon can be added to the raw materials. In the carbon content of gray iron castings, the carbon content is mostly 2.6% to 3.6%, and the silicon content is 1.2% to 33.0% . In the case of determining the wall thickness of gray iron castings, an appropriate amount of manganese should also be added. Grey Cast Iron Casting Using alloying methods to improve the tensile strength of gray iron castings, adding appropriate amount of trace alloys, chromium, molybdenum, tin and other elements can also significantly improve the tensile strength of gray iron castings, and do a good job of inoculating molten iron. Defect Once porosity or shrinkage occurs on the casting surface, it becomes a waste product. The looseness may first be caused by the unreasonable structure. Porosity, shrinkage porosity, and shrinkage holes are produced in areas wi...

As a   Grey Iron Casting Company , share it with everyone. After the heat treatment of gray cast iron, it can only change the matrix structure, not the shape of graphite, so it is impossible to significantly improve the mechanical properties of gray cast iron. The heat treatment of gray cast iron is mainly used to eliminate the internal stress and white structure of the casting, stabilize the size, improve the cutting performance, and increase the surface hardness and wear resistance. Grey Cast Iron Casting Relieve internal stress annealing It is used to eliminate the casting stress caused by uneven cooling of the casting during the solidification process, and prevent the casting from deformation and cracks. The process is to heat the casting to 500-600°C, and then slowly cool it with the furnace to below 150-200°C after holding it for a period of time, and then air cooling. Sometimes the casting is placed in a natural environment for a long period of time to relax the internal str...

As a   Grey Iron Casting Company , share it with you. The basic feature of high-density molding sand with gray iron castings is that the amount of pulverized is also lower. Therefore, the following points should be grasped while sand. Grey Cast Iron Casting 1. Clay content and mud. Sands with high clay content, and increased compression, high strength, usually effective bentonite controls at 7% to 10%. The sum of the effective clay and dead clay in the shaped sand is equivalent to the mud amount, and the mud contains generally controlled 12% to 16%. The mud is too high or too low, which will affect the performance indicators of the sand. 2. Moisture. The moisture in the production of disappeared castings is the main factor in determining the plasticity and bonding force of clay. When the water is too high, it is easy to cause deterioration of clay stickiness, and the fluidity of the sand is lowered, and the uniform mold density is not obtained. When the water is too low, the sand i...

Stainless Steel Casting Flanges Product Description OEM Service Custom stainless steel The investment casting process begins with a precise model (pattern) of the end product. For centuries this pattern has been made out of wax, however currently there are a variety of materials that are used. The model is then covered with a ceramic slurry which hardens to create a mold. The original model is then dissolved (for example, wax is melted and drained), and molten metal is inserted in its place. Once cooled and the mold removed (divested), you are left with the finished piece. In practice, modern Investment Casting  is a more sophisticated process that involves many more steps than described above. Sometimes it requires multiple model components, various modeling materials, etc., and like die casting, when done well, the resulting surface quality is excellent. Investment Casting   Typical steps : Create an aluminum mold (negative pattern) Wax injection (positive pattern) Assembly ...
