镍硬铸铁(Ni—Hard)是一种耐磨性能突出的镍铬白铸铁。近五十年来,它已在采矿、电力、水泥、陶瓷、喷镀、挖泥、炼焦、炼钢和铸造等行业中广泛应用。实践证明,这种合金白铸铁耐磨性极好,而且价格低廉。最典型的用途是做球磨机的铁球、磨机衬板、粉磨机辊圈、滚动头、砂泵内衬、管子和弯头、耐磨衬板、轧辊等。美国的许多机械制造厂都能生产这种铸铁。在与铬钼铸钢、高锰钢和铬钼铸铁的竞争中,镍硬铸铁价格最低。(因美国工资在产品成本中占主要比例,而镍 Nickel hard cast iron (Ni-Hard) is a nickel-chromium cast iron with outstanding wear resistance. For nearly five decades, it has been widely used in mining, power, cement, ceramics, metallization, dredging, coking, steelmaking and foundry industries. Practice has proved that this alloy white cast iron excellent wear resistance, and low prices. The most typical use is made ball mill ball, mill liner, roller mill roll, rolling head, sand pump lining, pipes and elbows, wear liner, roll and so on. Many U.S. mills can produce such cast iron. In the competition with chrome molybdenum steel, high manganese steel and chrome molybdenum iron, the price of nickel hard cast iron is the lowest. (Because the United States wages in the product cost accounted for a major proportion, while nickel
