Title: Controlled cooling of wide flat prod. - esp. for uniform cooling of hot steel strip
Inventor: BUDACH MARINA
IPC: C21D1/667
Filed: 1991-01-25
Abstract: Controlled cooling of a wide flat prod. (pref. of steel) during straight line motion using a liq. coolant involves the following steps carried out in any order and number for each section of the prod. (a) entry into a cooling device including active laminar cooling beams with coolant guides (4,5) which are arranged transverse to the travel direction of the prod. (11) to form a small enclosed coolant application area in which coolant is applied to the prod. top face, at least one of the active cooling beams allowing fine variation of the coolant application area extent transverse to the prod. travel direction at any instant of prod. passage through the cooling device; (b) coolant application without an active cooling beam being operative and/or coolant application with at least one active cooling beam being operative; (c) passage of a measuring device transverse to the prod. travel direction for approx. simultaneous surface temp. measurement of at least one prod. face (pref. the top face) at two or more points; (d) variation of the coolant application area of at least one operative active cooling beam in accordance with the measured surface temps. of the individual prod. sections; and (e) exit from the cooling device. USE/ADVANTAGE - The process is esp. useful for controlled cooling of wide hot strip steel or similar steel prods., but may also be used for cooling other metallic or non-metallic wide flat prods. It has reduced operating and investment costs, ensures minimal temp. variations across and along the prod. and uses minimal excess coolant (usually water).

Patent DE-4138264-A1 (DE)
Inventor: RADTKE UWE DR ING
IPC: H02J15/00
Filed: 1991-11-21
Abstract: A steam generating power station (1) has a steam generator (6), a steam turbine (26, 28), a condenser (36), a condensate line (38), a feed water reservoir (44) and a feed water line (46). Heat exchangers (42, 44, 50) are provided in the condensate line (38) and/or in the feed water line (46) to heat the feed water. These heat exchangers (42, 44, 50) are partially heated with bleeder steam. During temporary load peaks or power deficits in the network (68), the turbine power is increased in 20 to 40 seconds by blocking bleeding of bleed steam by means of a valve (54, 60) arranged in the bleed steam line (52, 58) that can be controlled depending on the load. Temporary load peaks can thus be partially regulated. Whithin the first 30 seconds, however, until this kind of power regulation intervenes, voltage breakdowns in the network are unavoidable. To solve this problem, a plant (4) has a supraconductive, magnetic energy accumulator (64) connected in the network (68) in parallel to the generator (2). When a power deficit occurs in the network (68), at first the supraconductive energy accumulator (64) intervenes, then increasingly the heat or steam accumulator. This invention is useful in all kinds of steam generating power stations.
