Alloy steel wear-resistant liner

Luocang zhongtai industrial co., LTD. Is specialized in producing wear - resistant castings in grinding equipment and spindle tile and towing tile of mill of various specifications. Its strong casting and forging, heat treatment and machining capacity, strict quality and process control methods, perfect testing and experimental means, so that its production and development of various wear-resistant products enjoy a high reputation in China, and sold overseas.

There are many kinds of alloy steel, usually divided into low alloy steel (content < 5%), medium alloy steel (content 5% ~ 10%) and high alloy steel (content > 10%). According to quality, it is divided into high quality alloy steel and characteristic alloy steel. According to the characteristics and USES, it is further divided into alloy structural steel, stainless steel, acid-resistant steel, wear-resistant steel, heat-resistant steel, alloy tool steel, rolling bearing steel, alloy spring steel and special performance steel (such as soft magnetic steel, permanent magnetic steel, no magnetic steel), etc.

Multielement medium complexing alloy steel casting: the medium chromium multielement alloy steel is developed by luokuang to meet the requirements of certain equipment to achieve the best economic results under specific conditions of use. It has a high hardness, toughness, in the occasion of small impact, such as crusher lining board, screen board and part of the ball mill lining board use show its advantages. Element of medium chromium multielement alloy steel

High requirements, long heat treatment time and complex process, high production costs, but is also the most commonly used wear-resistant steel material. I. main chemical composition (%)

C Si Mn Cr Mo Cu P S 0.38-0.46 0.7-0.9 1.3-1.8 5-7 0.5-0.7 0.5-0.7 ≤0.1 ≤0.1

2, impact toughness qk≥20J/CM2, toughness than high chromium molybdenum alloy cast iron, but poor than high manganese steel. 3. The service life is about 3 times higher than high manganese steel when the impact force is not too big. Iii. Recommend the use of products.

L, ZTIC production of crusher liner, screen plate. 2. Lining board and sieve board of the second bin of ball mill:

3. Lining board and jaw board of vertical kiln machine.

[4] high chromium molybdenum alloy steel castings, high chromium molybdenum alloy cast iron is a kind of wear-resisting material, in today's most anti-wear compared with high manganese steel has the advantages of high hardness and hardening layer in use process, less impact toughness than high manganese steel is poor, the production cost is high, in the use of clinker crushing and the impact is not big occasions shows its superiority. We control the chemical composition and unique heat treatment process to make the quality better than other similar products.

I. main chemical composition (%)

C Cr Mn Mo W Si P S

0.5-1.0 ≤0.1 ≤0.1

1. Initial hardness: HRC≥62

2, due to the high manganese steel used for clinker crushing lost its work hardening ability advantages, in the clinker broken appears incompetent, high chromium molybdenum alloy cast iron due to high hardness and service life can be high as high manganese steel 8 times. Iii. Recommended products:

L, luo mine production of adjustable high - fine crusher hammer head.

2, some cement factory used package hammer.

3, luo mine production with 800X600 hammer breaking machine alloy hammer head crushing clinker effect is also very good.

[4] carbon steel casting (' ZG35, ZG45, ZG35Mn, ZG45Mn) In addition to cement plant machinery and equipment use, other machinery and equipment factory also use many. In the production of carbon steel, luokuang adopts many technological methods to make the casting meet the steel standard completely, without porosity, shrinkage cavity and fine grain.

It is recommended to use ZG45Hn, ZG45Hn and ZG45 with high hardness, good impact toughness, abrasion resistance, and easy processing after annealing, such as gear, sprocket, coupling, ZG45Mn should be the best
