In spring 2022,Seven Refractories performed a challenging robotic stack repair for Erdemir's Blast Furnace 2 of Oyak Mining Metallurgy in Eregli.BF2 Eregli is a bell less medium size furnace arranged from the bosh to the armor zone with copper flat plate coolers.Igor Paladin,group installation manager of Seven Refractories,said:"We needed only four days for the entire repair,which was performed by modern shotcreting technique,performed with our robotic equipment.In four days of shotcreting,we applied approximately 500 tonnes of monolithics."A variety of shotcreting materials was chosen for each specific area of the furnace,bosh,belly,as well as lower,middle,and upper stack.During the shutdown operations,the burden had been brought to the tuyere level,and the stack was sufficiently cleaned to receive the new lining.We were very satisfied that we completed the project according to the plan,including the necessary safety training for our technicians and operators on site."
