Technical Field

[0001] The utility model relates to the technical field of ferrochrome crushing, in particular to a ferrochrome crusher used in the production of high-temperature resistant high-carbon ferrochrome. Background Art

[0002] Ferrochrome is the most important raw material for producing stainless steel. It is mainly used in the production of stainless steel, ball bearing steel, tool steel, nitriding steel, heat-resistant steel, quenched and tempered steel, carburizing steel and hydrogen-resistant steel. This is because chromium plays a decisive role in stainless steel. There is only one element that determines the properties of stainless steel, which is chromium. Each type of stainless steel must contain a certain amount of chromium. When ferrochrome is processed and produced, the ferrochrome raw material needs to be crushed, and a crusher is required.
