Wear resistant steel bar

At present, most enterprises use round steel rolled by steel mills, because of its low hardness, only 12-25HR; The internal stress of the round bar is not relieved (it is easy to break the bar and is not wear-resistant); The internal organization of round steel is loose and not tight, and so on. Because of these defects, round steel used as a grinding rod will have great wear, prone to bending, breaking, winding, thin tips at both ends, low output, failure to achieve the expected qualification rate, and large workload in the subsequent magnetic separation link. The new alloy wear-resistant steel bar produced by our company is produced by a new method, and the size specifications can be adjusted according to customer needs, and the flexibility is greatly improved, eliminating unnecessary waste. At the same time, it prolongs the service life, improves the production efficiency of the mill, saves production costs, and reduces the labor of workers.

Cast steel balls

Cast steel balls can be divided into three categories, including high chrome balls, medium chrome balls, and low chromium balls. 1. High chromium ball quality index The chromium content of high chromium balls is greater than or equal to 10.0%. The carbon content is between 1.80% and 3.20%. According to the national standard, the hardness of the high chromium ball must not be less than 58HRC, and the impact value should be greater than or equal to 3.0J/cm2. If this hardness is high, the chromium balls must be quenched and tempered at high temperatures. At present, there are two methods of domestic high chromium ball quenching, including oil quenching and wind quenching. If the high chromium ball test hardness is less than 54HRC, it means that it has not been quenched.

Forged steel balls

Forged steel balls have good surface quality, good impact resistance, strong toughness, good wear resistance, and are not easy to break and lose roundness. We use the method of forging and stamping, which is to heat the metal until the temperature reaches 1050ºC (±50ºC), and use forging machinery to apply pressure to the metal blank to produce plastic deformation to obtain a processing method of forgings with certain mechanical properties, certain shapes and sizes.

Double-in, dual-output mill liners

This kind of liner adopts a mature double-liquid vertical pouring process, and the working face and non-working surface are metallurgical and formed at one time. The working face is high hardness high alloy high chromium cast iron (HRC≥60 °), which is internationally recognized as the third generation of wear-resistant materials, is used as an excellent material for anti-abrasive wear, but brittle, directly used as a ball mill liner will break, unsafe, now the back of the composite layer of high toughness 35 steel, it solves the overall toughness of the liner, the impact toughness of the composite liner reaches ak>100J/cm², can be used in any mill Φ2500-5500. The corrosion resistance of high-chromium cast iron is also very strong, so the bimetallic liner is suitable for various wet grinding conditions of acid, medium and alkali. Another major feature of this liner is zero maintenance, it is almost no deformation, no breakage, overcoming the shortcomings of slurry leakage caused by easy deformation of ZGMn13 liner, frequent maintenance and replacement of tight bolts, and truly zero maintenance.

Rod mill liner

Bimetal liner

Lining plate of autogenous mill

This kind of lining plate adopts mature double liquid vertical pouring process, and the working face and non working face are metallurgical combined, forming in one time. The working face is made of high hardness high alloy high chromium cast iron (HRC ≥ 60 °), which is internationally recognized as the third generation wear-resistant material, and is an excellent material for anti abrasive wear. However, it is brittle, and it is unsafe to directly use it as the ball mill liner. Now a layer of high toughness 35 steel is compounded on the back to solve the overall toughness problem of the liner. The impact toughness of the composite liner is ak>100J/cm ²， Available for Φ 2500-5500 any mill. High chromium cast iron is also very resistant to corrosion and wear, so the bimetallic liner is suitable for various wet grinding conditions in acid, medium and alkali. Another major feature of this lining plate is zero maintenance. It is almost free of deformation and fracture. It overcomes the shortcomings of ZGMn13 lining plate, such as slurry leakage and powder leakage caused by deformation, and frequent bolt maintenance and replacement. It really achieves zero maintenance.
