Product Description
Brief Introduction |
Dafang is specialized in designing and manufacturing bridge cranes. Meanwhile, we are engaged in offering a full range of Industrial Craneaccessories, our wheels are technically advanced and successfully used in different industries like Steel P- lant, Rolling Mill, Cement Plant, Fertilizer Plant, Paper Mill, Chemical Industries etc.to cart heavy lode. Our wheel usually to be divided into two type : casting and forging. They areusually applied to overhead cranes gantry and portal cranes tran -sfer cars. |
The Difference Between Casting & Forging |
Casting is the process where metal is heated until molten. While in the molten or liquid state it is poured into a mold or vessel to create a desired shape. | Forging is the application of thermal and mechanical energy to steel billets or ingots to cause the material to change shape while in a solid state. |
Casting wheel | Forging wheel |
Why use castings? 1.We use castings for a wide range of wearparts and components that are too large, complicated,intricate or otherwise unsuitable for the forging process. We can forge parts up to 50kgs but the sheer energy required to forge larger irems make casting a much more viable alternative. 2.We currently cast mining and earthmoving components to 580 kg. We can cast up to 3000 kg if required. Mangane -se work hardening screens are one of our specialities. We have found that by carefully choosing alloys and applying proven methods of heat treatment, we can produce castings of high quality, strength and wearability. The casting pro- cess better lends itself to making parts where internal cavities are required. |
Why use forgings? Forging offers uniformity of composition and structure. Forging results in metallurgical recrystalisation and grain refinement as a result of the thermal cycle and deformation process. This strengthens the resulting steel product part icularly in terms of impact and shear strength. Forged steel is generally stronger and more reliable than castings and plate steel due to the fact that the grain flows of the steel are altered, conforming to the shape of the part. |
The advantages of casting include: • No real upper size limit in casting weight. • Large range of alloy choices. • As forgings remain solid, custom alloys are far more difficult to get into production whereas with cast alloys including Chrome, Nickel and Moly can be added at the molten stage. • Tooling is often less expensive than forge dies. • Smaller production “runs” required. • Complicated/complex parts are no problem. |
The advantages of forging include: • Generally tougher than alternatives • Will handle impact better than castings • The nature of forging excludes the occurence of porosity, shrinkage, cavities and cold pour issues • The tight grain structure of forgings making it mechanically strong. • The tight grain structure offers great wear resistance without the need to make products “superhard” We have found that, on a blank HRC 3842 forged grinder insert wear/wash is about the same as a high alloy HRC 46-50cast grinder insert. |
Wheel Features |
1.Material: The casting wheel material generally is 50SiMn, ZD45,ZG55. The forging wheel material generally is DG65Mn and 42CrMo. 2.Treatment: The heat treatment is quenching or hardening and tempering. 4.Inspection: In-house and the third party.Inspection:all items are checked and tested thoroughly during every working procedure and after the product is finally manufactured to ensure that best quality product goes out in the market. |
Equipments and Production |
Production process of our factory and some equipments.
Blank→Rough maching→Annealing treatment→Quenching and tempering→Finish maching→Testing
Wheel Testing |
1. Dimensions testing.
2. Hardness measurement. (HB, HS,HRC)
3. Material testing.
4. Superficiality testing.
5. Non-destructive testing.
Packing and Delivery Pictures |
What should we know when you placeing an order: 1. Product drawing(most important), so we can know the size, thickness, groove and so on. 2. The process?casting or forging? 3. What material? 4. How many dou you need? 5. If you have specific request of the heattreat? Of course, we hope you can offer more and more information about your product, but the drawing is the most important thing. |
