Multiple Medium Complexed Gold Steel Wear-Resistant Castings And
Forgings
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 multiple complex steel castings and forgings
Medium chromium multi-alloy steel is a kind of steel developed by
Lo mine to meet the requirements of some equipment to achieve the
best economic effect under specific conditions. It has high
hardness, good toughness, in the impact of small occasions, such as
crusher lining plate, sieve plate and part of the ball mill lining
plate use show its advantages.
Medium chromium multi-alloy steel requires high alloy elements,
long heat treatment time and complex technology, high production
cost, but it is also the most commonly used wear-resistant steel
material.
3. Multiple complex steel casting castings and forgings product parameters
| Main chemical composition(％) | Parameters | Note |
| C | 0.38-0.46 | |
| Si | 0.7-0.9 | |
| Mn | 1.3-1.8 | |
| Cr | 5-7 | |
| Mo | 0.5-0.7 | |
| Cu | 0.5-0.7 | |
| P | ≤0.1 | |
| S | ≤0.1 | |
4. Performance indicators of multiple complexed steel castings and forgings:
(1) Hardness HRC＞50;
(2) Impact toughness QK ≥20J/CM2, toughness is better than high
chromium-molybdenum alloy cast iron, but worse than high manganese
steel.
(3) When the impact force is not too large, the service life is
about 3 times higher than that of high manganese steel.
5. It is recommended to use multiple complex steel casting
products:
(1) Luo mine production of crusher lining plate, sieve plate;
(2) Ball mill two bin lining plate, sieve plate, etc.
(3) Lining plate and jaw plate of vertical kiln machine.
