With the expansion of steel and copper production chain in Kerman province and the increase in the number of related mining units and factories producing concentrates and raw products such as DRI and steel and copper products, the country’s need for spare parts required by these industries is expanding. Since the mentioned industries are mostly heavy industries, the spare parts used by them are mostly in the category of steel and heavy cast iron parts. Due to the country’s economic conditions that have placed obstacles in the way of imports and the heavy weight of such parts, the production of heavy spare parts such as rolling rolls, melting pots and slag, mining wagons, billet castings and similar items has become a national necessity. Unfortunately, domestic producers of such parts are few and with the transformation of Kerman province into a big mineral, steel and copper pole, the need to produce spare parts for the mentioned industries in this province is felt more than ever.
