Abstract
The invention relates to ferrous briquettes made of pulverous ferrous waste and to a process for making them, the briquettes being meant to be used in the steel and metallurgical industry as a raw material replacing scrap iron waste, and the process being intended to help to eliminate dumps with waste products harmful for the environment. The claimed ferrous briquettes comprise between 60...90% Fe, are egg-shaped with a diameter of 10 cm and have the following composition expressed as percentage by weight: 40...60% dross, 2...4% silicate, 20...30% ferrous sludge, 3...5% bentonite, 2...4% ecological binder, 2...4% lime and 0...4% metal shavings obtained by shredding, on a Schrreder-type shredding machine, the waste from various metal packaging such as food cans, beverage cans, paint cans and the like. The claimed process has the following steps: a. introducing pulverous ferrous waste and Fe-containing sludge into the thermal desorption plant to remove all hydrocarbons from the content, b. crushing the waste and sorting it on vibrating sieves where it is screened as grain size fractions of 0...0.1 mm, 0.1...0.5 mm and 0.5...1 mm, c. making the final mixture by mixing for 30 minutes the resulting ferrous waste with a quantity between 2...4% ecological binder, 2...5% bentonite, 2...4% silicate and 0...4% metal shavings, d. introducing the final mixture into a rotary press with egg-type moulds, with a roll diameter of 650 mm and a pressing power between 37...45 kw, resulting in unburned ferrous briquettes, and e. the last step being the sintering of the briquettes in an electric furnace for 45 minutes at a temperature of 1250°C.
