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

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.
