High Chromium Molybdenum Alloy Steel Cast Iron Castings For Crusher
High Chromium Molybdenum Alloy Steel Cast Iron Castings And Forgings For Crusher
1. Product description of alloy steel wear-resistant lining board castings and forgings
Luokuang Zhongtai industry can be specialized in the production of wear resistant castings in grinding equipment and various specifications of grinding machine spindle tile, tile. Its strong casting, forging, heat treatment and machine adding capabilities, strict quality and process control methods, perfect testing and experimental means, so that its production and development of all kinds of wear-resistant products enjoy a high reputation in China, and exported to overseas.
There are many kinds of alloy steel, usually according to the content of alloy elements into low alloy steel (content < 5%), medium alloy steel (content 5% ~ 10%), high alloy steel (content > 10%); According to the quality is divided into high quality alloy steel, special alloy steel; According to their characteristics and uses, they can be divided into alloy structural steels, stainless steels, acid-resistant steels, wear-resistant steels, heat-resistant steels, alloy tool steels, rolling bearing steels, alloy spring steels and special performance steels (such as soft magnetic steels, permanent magnetic steels, non-magnetic steels), etc.
2. Introduction of high chromium molybdenum alloy steel cast iron castings and forgings
High chromium-molybdenum alloy cast iron is one of the most wear resistant materials nowadays. Compared with high manganese steel, it has the advantages of high hardness, less hardening layer in the process of use, worse impact toughness than high manganese steel, high production cost, and shows its superiority in the use of clinker crushing and little impact. We control the chemical composition and unique heat treatment process, so that the quality is better than other similar products.
3. High chromium molybdenum alloy steel cast iron castings and forgings product parameters
| Main chemical composition(％) | Parameters |
| C | 2.8-3.2 |
| Cr | 19-22 |
| Mn | 0.5-1.0 |
| Mo | 1.0-1.5 |
| W | 1.7-2.2 |
| Si | 0.5-1.0 |
| P | ≤0.1 |
| S | ≤0.1 |
4. High chromium molybdenum alloy steel cast iron castings and forgings performance index
(1) Initial hardness: HRC≥62;
(2) Due to the advantages of high manganese steel for clinker crushing to lose its work hardening ability, it is unable to break the clinker. The service life of high chromi-Mo alloy cast iron can reach 8 times that of high manganese steel because of its high hardness.
5. It is recommended to use high chromium molybdenum alloy steel cast iron castings and forgings products
(1) Hammer head of adjustable high fine crusher produced by Luo mine.
(2) Some hammer used in cement factory.
(3) The alloy hammer head of φ800x600 hammer breaking machine produced by Luo mine is also very good for crushing clinker.
