2.1. High-chromium white cast iron characteristics. High-chromium white cast irons are ferrous alloys containing 11-30 Cr and 1.8-3.6 C along with variable amounts of molybdenum manganese copper and nickel 1. The standard procedure most commonly used for the classification of this kind of cast iron alloy is ASTM A532-10 2014.
Dias et al. 9 researched the effects of gray cast iron matrix structure on the cutting force and tool life in milling operations. They found that the higher pearlite content led to faster tool.
Jun 22 2011 In this study turning test of high chromium cast iron is carried out. From the results ceramic tool is the most suitable for machining of this material but the cutting speed more than 5 ms and wet cutting must be avoided. From the diffusion reaction experiment it is shown that P 10 has obvious diffusion layer and cermet tool has not..
The production of vertical mill nozzle vertical mill nozzle is in the long-term research and development and production experience based on various models of the vertical mill of the specific circumstances of the vertical mill.TGM disc surrounding annular nozzle has been specially designed to reduce the flow resistance of the nozzle to prevent the flow of air nozzles blowing upward grinding.
such as high chromium cast iron and Ni-hard cast iron which would consume a large amount of ex-pensive alloying elements. In addition high chro-mium white cast iron and Ni-hard cast iron are still a kind of brittle material this fact restricts their ap-plication under serious work conditions.
White cast irons with content of chromium in particular known as abr asion resistant cast irons contain enough chromium to prevent continuous iron carbides Fe 3 C or M 3 C formation. Normally.
It is shown that high-chromium cast iron which has undergone accelerated cooling in the mold directly after cooling possesses the properties required of the grinding elements of impact mills.
Apr 29 2014 High chromium cast iron is one of the wear resistant materials used in a variety of applications where stability in an aggressive environmental is a principal requirement. These applications include slurry pumps brick dies several pieces of mine drilling equipment rock machining equipment and similar areas 1 2.
West Salisbury Foundry can produce 15 and 25 Hi-Chrome alloy iron used in applications of wear resistance and long term heat resistance are required such as impellers turbines and grinding applications.
First recommendation for cast iron milling. MC5020 has excellent wear resistance and also controls thermal cracking and chipping that are common when machining ductile cast iron. Black Super-smooth Coating Black super-smooth coating prevents abnormal damage such as weld chipping.
Aug 09 2006 The castings seem to be high quality with no discernable embedded sand particles. I do a lot of aluminum casting and these cast pieces are much cleaner than I am able to produce. I have been doing milling on other castings in the project. There do not seem to be chips just very dirty dust which I assume is from the high carbon content of iron.
High Chromium White Cast Iron or High Cr White Iron grades are used in wear applications that require some corrosion resistance. One common application using High Chrome White Iron alloys is in Pump and Valve parts for the Mining industry. The high chromium content offers the corrosion resistance and the fine carbides dispersed throughout.
Iron CastingDuctile cast ironHigh chromium cast iron. Jiangsu Humboldt wear-resistant materials Co. Ltd. is located in Haian ProvinceJiangsu County.Company is the TGM subsidiary affiliated to the TGM group. Our company is the advanced green environmental protection epc casting process and research all kinds of gray cast ironhigh manganese.
High chromium white cast irons are an important class of wear resistant materials. Their exceptional wear resistance is the result of their high carbide content which forms along with austenite during solidification as a pro-eutectic or eutectic phase depending on alloy composition and particularly depending upon carbon and chromium content.

The invention discloses a heat-treatment method of high-chromium wear-resistant white cast iron Cr28. According to the invention high-chromium wear-resistant white cast iron Cr28 is heated to 1000-1050 DEG C; the white cast iron Cr28 is heated and the temperature is maintained for 1.5-3h; the white cast iron Cr28 is air-cooled to room temperature; the white cast iron Cr28 is heated to 710-730.
One material used widely for components working in conditions of intensive abrasive wear specific for mining ceramic cement and aggregate processing industries is the high-chromium cast iron 2.
High-chromium irons have good mechanical properties high hardness in a cast state low fluctuation of hardness when properties change. High-chromium irons almost dont concede in fluidity to regular gray cast iron that allows using parts sufficiently difficult form directly after casting without the following machining.
Jun 01 2008 1.. IntroductionHigh-chromium white cast irons are in demand for the mining mineral processing metallurgical and cement industries. Very high abrasive wear resistance combined with relatively low production costs make these alloys particularly attractive for applications where grinding milling and pumping equipment is used to process materials such as ore coal and gravel .
