1 COMPLEX FOR THE PRODUCTION OF THE FLUIDIZED LINE

2 The main problem when using the lime is the fraction of 10 and less millimeters, and the use at the enterprises of the lime of this fraction in the production technology is complicated because of some reasons: gas permeability of furnace charge decreases with the growth of bursts of dust ; increased dustiness, % (carrying out lime with gases from steel-smelting units) and adverse effect on the ecological situation; quick liming (react with humidity in the air) that results in hydrogen loading to the metal; raised load of the system of deleting gases and dust. Thus approximately 15% of the consumed lime s total volume is out of operation while producing additional negative industrial, commercial and ecological risks.

3 The proposed solution of the above described problem consists in the organization of production of the fluidized lime which allows to solve the mentioned problems, namely: to use completely in the production the formed waste of lime; to increase productivity of the main aggregates of smelting of steel of cast iron; to receive a highly effective material for the cast iron and steel desulfuration; to receive a highly effective material for the cast iron and steel desulfuration with the injection processing; to lower an environmental loading of the enterprise.

4 Doesn't hydrate; Doesn't become caked; Possesses the increased flowability, it is transported by means of any mechanical and pneumatic equipment; Has the long term of storage without deterioration of consumer properties; Possesses high reaction capacity, will quickly form homogeneous slag, the active desulfurator; Is ideally suited for inflation in a melt (injection processing) cast iron and steel; It is eco-friendly, doesn't create a dust content when using and transporting.

8 Crushing attrition bending cleavage free hit Average operation of grinding with the hit = 50% from the operation of grinding with crushing. In case of hit the force of compression arises so quickly that the crack forms even before the establishment of the equilibrium distribution of energy. specific power consuming is 15-20% lower low milling of metal in a readymade product

9 the material acquires the isometric form of grain with an extended surface narrow grain composition of the crushed material there is no sticking of the material to grinding bodies, considerably smaller tendency to aggregation - end-to-end solution (the "turnkey" line)

11 decrease in the overall level of steelmaking rejects; secondary refining time reduction along with the increase in efficiency of all production chain; optimization of the steel manufacturing main units performance; expansion of the range of products through the production of highly expensive and cost-effective grades of steel with very low sulphur content.
