Thanks to support for local producers, MSC won’t import rolling oils


In line with the policies of Mobarakeh Steel Company (MSC) to support local knowledge-based companies, the steel giant’s experts have in cooperation with Aryan Sanat Company developed the technical know-how to make the oil used in the five-stand tandem rolling mill of Mobarakeh Steel Company.
The new development eliminates the need for the steelmaker to import such oil and results in 120 billion rials in annual savings.
“After MSC experts developed the know-how to make the oil that is used in the two-stand mill, they decided to take one step further. As a result, they managed to acquire the knowledge to make the oil that is used in the five-stand tandem mill,” the head of MSC’s cold-rolled lines said.
Mahmoud-Reza Ghermezi described the oil that is used in cold-rolled mills as a strategic consumable, adding that in cold rolling, after pickling in continuous tandem mill, a mixture of demineralized water and oil is sprayed at steel sheets at room temperatures to decrease their thickness as per customer order.
He went on to say in light of the fact that state-of-the-art technology is needed for the production of such oil, only a small number of companies in the world can produce it. Five years ago, MSC experts in cooperation with other local firms worked out the formula of the oil used in two-stand mills. That development resulted in 100 percent indigenization of the product. Immediately afterwards, studies were launched to develop the technical know-how to produce the oil that is used in continuous tandem mills. In light of the fact that the oil that is used in continuous tandem mills is different from that of two-stand mills since it involves larger scales and diverse grades, laboratory tests were conducted in 2014 and it became clear that successful production of such oil at home required more research.
The complementary tests were launched in November 2017 and ran for three months. At times, the local oil performed even better than the foreign-made oil. In the second month of testing, the amount of oil used in the production of each ton of steel decreased by as much as 250 grams. The results of tests at downstream lines confirmed the high quality of the locally-made oil, he said.
The official went on to say indigenized production of the oil cuts dependence on foreign firms and prevents the outflow of foreign currency. In addition, it eliminates costs associated with warehousing, placement of orders, transportations and customs clearance. What is also equally important is that easy access to producers makes it possible to change the composition of oil if and when rolling conditions undergo change.
In conclusion, he thanked the management of the cold rolling plant, the manager of the raw materials and energy department, the personnel of the cold rolling plant and the technical staff and the company that has produced the oil.
Meanwhile, Mohammad Riyahimanesh, the managing director of Isfahan’s Aryan Sanat Company, said the indigenized oil is up to par with imported oil and said thanks to a raft of features, it can compete with foreign-made products overseas: introduction of technical change to the product in accordance with production line conditions at the shortest time span possible and at the lowest cost; consumption of no more than 250 grams of such oil per ton when the production line runs normally; top-quality rolling when the oil viscosity stands at 0.5 and 2.5 percent; a buffer resistant to PH and conductivity changes; resistance to surface corrosion given that the emulsion contains 25 ppm of chlorine; resistance to oxidation in condensed air and temperatures above 60º C and to chloride anion; limited production of iron powder that eliminates the need for several magnetic filters; high levels of cleanliness when it comes to what rolls off the tandem mill and the final production lines; cleanliness of housings and stands; the fact that new emulsion does not have to be made and the reduction in the volume of water consumed; use of grit rollers in the fifth stand without compromising surface cleanliness and roughness; standard roughness of the sheet surface that does not lead to accumulation of oil; although the surface oil is thick, it does not fluctuate; cleanliness of the products at the tandem exit without the need for an increase in iron levels; and average cleanliness of 75 percent and more at final production lines.
Riyahimanesh further stated that the development has also paved the way for improvement of other parameters such as a decline in water consumption levels, a decrease in the amount of oil outflow, and a decline in the freezing point of oil while it maintains its performance.
As for the economic and commercial benefits of the project, he said the indigenization lends support to Iranian production, creates jobs, reduces the risk of untimely customs clearance and cuts the costs of warehousing. The presence of Iranian products on the local markets also results in a decline in the prices of foreign-made items, he said, adding when a company buys a locally-made product, it can pay out its prices post-delivery but in buying from overseas suppliers the price should be paid fully in advance of actual shipment.
