Title: Method for regulation of thermal conditions in railway tunnels at winter period
Inventor: GENDLER S G
IPC: E21F1/00
Filed: 1998-05-07
Granted: 1999-08-10
Abstract: FIELD: mining industry. SUBSTANCE: method relates to ventilation of mine workings and for separation of harmful substances and it also can be used for regulation of thermal conditions in railway tunnels located in regions with severe climate. According to method, outside air delivered into tunnel and into entry parallel to tunnel at no transportation facilities in tunnel is initially heated up to 2 C. Then, outside air is divided into two parts, one part is directed to entry, and other part of outside air is heated up to temperature which is determined by condition of preventing processes of creating ice covering. This temperature is determined according to relation given in description of invention, and after that air is delivered into tunnel. In case of transportation facilities present in tunnel, delivery of air into working parallel to tunnel is discontinued and entire volume of heated air is directed into tunnel following train moving ahead. Temperature of final heating is determined according to relation given in description of invention. Application of aforesaid method ensures effective ventilation of tunnel together with reduction of power cost and with creation of positive thermal conditions excluding formation of ice covering. EFFECT: higher efficiency. 1 cl, 1 dwg

Title: Method of production of doped alloy containing refractory metals tungsten and molybdenum by technology of liquid-phase reduction
Inventor: VIL DANOV S K
IPC: C22B5/10
Filed: 1998-05-06
Granted: 1999-08-27
Abstract: FIELD: ferrous and nonferrous metallurgy, particularly, pyrometallurgical processes in which valuable components are reduced from liquid slag phase. SUBSTANCE: method includes slag melting under strictly defined conditions in compliance with the process of liquid-phase reduction, particularly, use of iron and lime-containing component in the form of oxygen-converter slag. Most suitable for normal running of process of processing of materials containing tungsten and molybdenum are highly basic slags characterized by basicity index CaO/SiO 2 =1.5-2.0. Concentration of ferrous oxide in such slags is maintained at the level of 10-20%. This is due to the fact that ferrous oxide materially reduces viscosity of highly basic slags to extend interval of crystallization of the slags and increases concentration of doping elements in final alloy. Besides, highly basic slag bath prevents foaming of oxide melt to prevent undesirable situations involving spitting of slag from melting unit. The method allows recovery from wastes of tungsten and molybdenum into final alloy where their concentration considerably rises. The wastes containing refractory elements are practically not usable. EFFECT: higher efficiency. 2 cl, 2 dwg
