Advantage of B imetal H ammerhead Hammerhead is a key component on the hammer crusher used in building materials, mining, chemical industry, etc. It is also a wearing part. The traditional hammerhead is mostly cast with high-manganese steel , and the high-manganese steel is used to improve the wear resistance under the impact load, but its wear resistance is far from being suitable for the modern production demand of high efficiency and low consumption. Due to the short life of the hammer and frequent replacement, the equipment operation rate is reduced. Therefore, it is necessary to seek a new material and new technology to improve the function and service life of the hammer. When the hammer head does not change its surface shape at the beginning of the work, the hammer head is mainly subjected to impact wear, and the material impacts the metal surface with a positive force to cause plastic deformation and impact craters. When the working surface of the hammer head is ground...

Then, the iron ore price has risen sharply within half a year, what impact will it have on domestic related companies? In addition to traders stepping up to inventory, steel companies are also stepping up shipments. The person in charge of a steel company in Hebei told the reporter that at present, the sales profit of downstream finished products has actually not kept up with the increase in raw material prices, but if it does not increase the strength of the warehouse, it is likely ...
