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.
