to design and internalize madaba steelmaking furnace. the equipment with its construction leads to annual savings of more than 4 million dollars. the cooling port of the furnace is responsible for lowering the temperature of the melting furnace in the steel production process. the equipment used in the production line of steel companies was supplied from european countries. but now it has been localized by a domestic company, the installation of hydroelectric panels , design, construction, engineering, delivery, and after-sales service are done in the same company. previously , it was imported from abroad and manufactured by a german company. its installation is done by young people who are from the university they stepped into the industry, we do reverse engineering and... we present to the workshop to make the parts that are designed for the first time . we can use this many times in the construction of the iranian example of the cooling port of the furnace, the charging rate of this equipment to madaba furnaces to reduce the temperatu
