More Than AK10J. Product Name Ball Mill Liners. High Chrome Cast Iron Chute Liners Grinding Mill Liners. Mining Industry. Summarization. High Cr white iron material possess a combination of superior abrasion resistance and a reasonable. degree of toughness. The high Cr castings have longer service life than the other material,such as.
or for thinner section liners. 3. High Carbon Chrome Moly Steel (325 to 380BHN) This steel is now considered the main material used for SAG mill liners. There are a number of variations with either different carbon or chrome contents. The variations tend to have a bearing on the size of the liner and its section thickness.

High chrome white iron cast alloys superior wear resistance is due primarily to a high volume fraction of very hard, well-dispersed primary and secondary carbides in a matrix of martensite. The high chromium content provides good resistance in corrosive environments and good oxidation resistance. COMPOSITION. C % 2.0 - 3.5. Mn % - 1.5 max.
At a high ratio, abrasion resistance is high, but when the ratio drops below 0.6 there is a wide scatter and the slope of the curve indicates the decreasing influence of metal hardness. Unfortunately, many minerals contain quartz or silicates which are as hard or harder than metallic alloys. But even when the abrasive is harder than the metal,

Apr 02, 2017 Some interesting tests of manganese-steel liners have also been made on a Schmidt-Davidson type mill in operation in New Zealand. This mill is 4 ft. 6 in. in diameter and is run at 23 r.p.m., which was found, to be the most effective speed when using lifting bars. The liners in this case were of hard, white cast iron made at a local foundry.
Apr 30, 2017 Chrome-magnesite material usually contains 15 % to 35 % Cr2O3 and 42 % to 50 % MgO whereas magnesite-chromite refractories contain at least 60 % MgO and 8 % to 18 % Cr2O3. Chrome- magnesite refractories are used for building the critical parts of high temperature furnaces.
Aug 29, 2015 The effect of chemical composition, microstructure, and applied loads on abrasive wear resistance of a group of high-Cr white cast iron (HCCI) alloys with different Cr/C ratios was investigated. In the present study, the microstructures of all HCCI alloys consist of a network of M 7 C 3 eutectic carbides in an austenitic matrix as mentioned above.

Refractory liners for slagging gasifiers are typically of two types, high chromia-alumina, and high chromia-alumina-zirconia, with some historical use of chromia-magnesia linings. The use of high chromia refractories evolved from gasifier research in the mid 70s to 80s, which indicated high chromia content in a refractory
High Carbon Chrome Moly Steel (325 to 380BHN) This steel is now considered the main material used for SAG mill liners. There are a number of variations with either different carbon or chrome contents. The variations tend to have a bearing on the size of the liner and its section thickness.
Sep 22, 2016 This combination makes chrome white iron exceptionally wear resistant and hard. The carbides in chrome white iron have a hardness range of 1500-1800HV and are primarily eutectic carbides. They form as bundles of hollow hexagonal rods. The growth of these rods will drastically affect the properties of the casting, which is controlled through the careful
HIGH CHROMIUM ALLOY MARTENSITIC WHITE IRON. DESCRIPTION. High chrome white iron cast alloy is a high alloy martensitic white iron with an excellent abrasion and corrosion resistance. Section thicknesses of up to 8 inches can be fully air hardened.
Sep 24, 2015 High Chrome White Iron (ASTM A532) High chrome white iron is composed of Carbides and Martensite (among the hardest phase of iron alloys). This combination makes chrome white iron exceptionally wear-resistant and strong, but gives it virtually no toughness. When solving wear-related problems chrome white iron should be one of the first materials
The balance of the composition is Fe with only incidental impurities, such as sulphur (S) and phosphorus (P). Mn is added to supplement the Cr content, particularly in balls of larger diameter. A high C content (i.e. 0.85%) in the forged steel balls leads to a reduction in toughness, which usually causes spalling of grinding balls. This is due ...

The most common material used to produce the load carrying components in precision ball bearings, roller bearings, and tapered roller bearings is 52100 chrome steel. These components are the bearings inner and outer rings, balls and rollers. The chemical composition of this steel has high carbon and about 1.5% chromium content.
Mill internals such as body liners and diaphragm grates are subjected to significant impact and wear. Depending on the application and mill size, the company supplies the wear parts in a wide range of high-chrome compositions , chrome varying from 2% to 28%.
Bore and hone the liner as parallel as you can. An auto-parts store break-hone will help achieve this, and leave a nice cross-hatch pattern in the bore that is favoured for oil retention. Sections of aircraft chrome-molly tube can be honed easily to an excellent liner for this type of engine.
The three popular types of top compression ring face coatings, chrome, moly, and cast iron, each has advantages of its own with respect to operating conditions. Moly has a very high resistance to scuff. Chrome has good resistance to scuff but does not exhibit molys oil retention capabilities.
