Product Description

Steel forging is a kind of wear-resistant material, the chemical composition is similar to the grinding ball,steel forging is divided into double plane and bispherical(capsule type),mainly used in the ball mill fine grinding silo,it can withstand high frequency of strong impact force and friction,with fine grinding effect,high wear resistance,low crushing rate characteristics,effectively reduce production costs.

High chromium wear-resistant steel forging is a kind of chromium white cast iron. The production process of high chromium wear-resistant steel forging includes melting high-quality scrap steel, chromium alloy and other alloy materials, and then through micro-alloying treatment, tempering, and finally using sand casting. After high temperature quenching and tempering treatment, martensitic matrix can be obtained, thus achieving high hardness and wear resistance.

 

 

High chromium wear-resistant steel forging is widely used in industrial fields, especially in the powder preparation and ultra-fine deep processing in cement, mining, coal slurry thermal power and other industries, which improves the grinding efficiency, reduces the shutdown time and the number of times of opening and shutting down, extends the clearance cycle, and reduces the labor intensity of workers. At the same time, it is of great significance to increase the output of the mill, ensure the quality of the abrasive, and reduce the power consumption and the consumption of the grinding body.

Excellent wear resistance: The chemical composition of the high chromium alloy wear layer has a high carbon content, and the chromium content is as high as about 30%, the volume fraction of Cr7C3 carbide in the metallographic structure reaches more than 50%, and the macroscopic surface hardness is HRC56~62, which makes its wear resistance significantly improved.

Good impact resistance: the substrate is low carbon steel or low alloy steel and other ductile materials, wear-resistant layer combined with the substrate, showing good impact resistance, suitable for bearing high drop hopper and other impact and wear material handling system.

Good corrosion resistance: Because the alloy layer contains a high percentage of chromium metal, it has a certain rust and corrosion resistance, which is suitable for the occasions of easy adhesion materials

Company Profile
Shijiazhuang Chengda Wear resistant materials Co.,LTD. a certified ISO 9001Company, specializes in the design, development, production, and servicing of high chromium wear resistant materials for grinding equipment in cement, mining and quarry industries. 
CHENDDA manufactures High chromium cast grinding media which is wear, corrosion and impact resistant helps in efficient ball mill grinding.
Our grinding media is tailor made for each milling application. There is a wide range of alloying options which are decided after adequate test work and technical analysis. We manufacture grinding media with chrome content ranging from 1 % to 30 % in sizes ranging from 15 mm to 140 mm as required by the application
Big balls, ranging from 140 mm to 60 mm, Chrome range from 10% - 28%,Optimal Hardness ranging from 57 - 66 HRc , are essentially used in the first chamber of the mills for crushing the feed material. These balls impart potential energy for crushing and thus required to possess a combination of wear and impact resistance
Grinding by attrition is accomplished by numerous small balls of varying sizes from 15mm to 60mm,Chrome range from 10% - 30% and Optimum Hardness ranging from 60 - 69HRc in second chamber. These balls contribute significantly to the grinding efficiency of the mills. Quality control of the final product depends much on the quality of the balls used.
Our commitment is to deliver reduction in wear cost, improve equipment availability, enhance mill productivity, reduce energy cost (Carbon foot-print) and improve metal recoveries through optimization in flotation process. With a legacy of more than 20 years in China , we have set benchmarks in quality, services and innovation, establishing a strong reputation as a solution provider.
