High Chromium Cast Iron Products Castings And Forgings For Mill
1. Introduction of high chromium cast iron Castings And Forgings
High chromium cast iron (chromium > 12%) is an excellent wear resistant material. In the study of high chromium cast iron, generally concentrated on Cr15, Cr20 and other high chromium cast iron. This paper analyzes the influence of ultra high chromium cast iron (chromium content > 20%), an important component of high chromium cast iron, on the changing properties of the studied microstructure with the increase of Cr content and the addition of various alloying elements.
2. Different types of high chromium cast iron each component content is different:
| Chemical composition | Percentage % |
| C | 2.05 |
| Si | 1.40 |
| Mn | 0.78 |
| Cr | 26.03 |
| Ni | 0.81 |
| Mo | 0.35 |
3. Heat treatment process of high chromium cast iron Castings And Forgings
(1) The commonly used heat treatment process of high chromium cast iron is heated to 950~1000℃, and then quenched after heat preservation and air cooling 200~260℃ low temperature tempering.
(2) High temperature pelletizing treatment 1140~1180℃ for 16h air cooling, can significantly improve the impact toughness and wear resistance. The high temperature pelletizing treatment can make all carbides spheroid, which can eliminate or reduce the separation effect of large bulk and continuous network carbides on the matrix. The carbides spheroidized by the pelletizing are supported by more uniform matrix, especially by a certain amount of austenite. If the holding time is properly reduced, the effect can also be achieved on thin section parts. The disadvantage of this process is that it consumes more heat energy.
(3) The mature process is: softening annealing after casting, easy to process, air cooling quenching and low temperature stress tempering after processing. The hardness is generally required to be HRC58-62, which is mostly used for wear-resistant and wearing parts such as slag slurry pump parts.
(4) We here is a high chromium production base, generally provide Cr24, Cr26, Cr28, Cr15Mo3, Cr26
Do high chromium grinding ball, Cr%=10.2~10.5%, C%=2.2~2.7%, Si, S double zero below, required hardness HRC> 58 We are using the quenching liquid to quench. The quenching process parameters are: 650 ℃ for 2 hours, rising to 960℃ for 3.5 hours; Tempering temperature 380~400℃, holding for 4~6 hours. Grinding ball specifications φ40-φ80. The process is 1050℃, quenching 250~350℃ tempering.
