摘要： The invention relates to a wear detection probe (24) and cooling element featuring with the wear detection probe (24) embedded therein. The wear detection probe (24) includes a plurality of conductive loops (28) positioned at predetermined depths below the front face of said cooling plate body and are electrically insulated therefrom, each loop being connected to a pair of terminals (30) on the rear face of the body, so that wear of said body can be detected by a change of an electrical characteristic of a said loop(s) due to abrasion. The conductive loops are formed as U-shaped conductive lines on a board (42). The probe (24) is arranged in a through bore (26) or blind bore in the body. The probe (24) comprises a cylindrical housing surrounding said board with said conductive loops, the cylindrical housing having a shape matching the shape of the bore. The cylindrical housing is made from the same material as the cooling plate body (12).

摘要： In a charging process of a shaft furnace, in particular of a blast furnace, batches of charge material are typically discharged in cyclical sequence into the furnace from a top hopper using a flow control valve. A method and system is proposed for adjusting the flow rate of charge material in such a process. Pre-determined valve characteristics for certain types of material are provided, each indicating the relation between flow rate and valve setting for one type of material. According to the invention, a specific valve characteristic is stored for each batch of charge material, each specific valve characteristic being bijectively associated to one batch and indicating the relation between flow rate and valve setting of the flow control valve specifically for the associated batch. In relation to discharging a given batch of the sequence the invention proposes: using the stored specific valve characteristic associated to the given batch for determining a requested valve setting corresponding to a flow rate setpoint and using the requested valve setting to operate the flow control valve; determining an actual average flow rate for the discharge of the given batch; correcting the stored specific valve characteristic associated to the given batch in case of a stipulated deviation between the flow rate setpoint and the actual average flow rate.

摘要： The present invention proposes a bustle pipe arrangement (10) of a shaft furnace, in particular for feeding hot gas into the shaft furnace such as e.g. a blast furnace, wherein the bustle pipe arrangement (10) comprises a circumferential bustle pipe (12) arranged along the outer casing (14) of the shaft furnace, the bustle pipe (12) being arranged at a certain distance form the outer casing (14). The arrangement (10) further comprises a plurality of first arms (22) connecting the bustle pipe (12) to the outer casing (14) of the shaft furnace; and a plurality of second arms (24) connecting the bustle pipe (12) to the outer casing (14) of the shaft furnace. First and second blow channels (26, 30) are respectively arranged through the first and second arms (22, 24) for fluidly connecting the bustle pipe (12) to the interior of the shaft furnace.

摘要： A multiple hearth furnace comprises a gas cooling system for its central shaft (20) and its rabble arms (26). This gas cooling system includes within the shaft (20) an annular main distribution channel (54, 54') for supplying a cooling gas to the rabble arms (26) and a central exhaust channel (56) for evacuating the cooling gas leaving said rabble arms (26). The gas cooling system further comprises an annular main supply channel (52, 52') surrounding the annular main distribution channel (54, 54') and being outwardly delimited by an outer shell (50) of the shaft. A cooling gas inlet (44', 44') is connected to the annular main supply channel (52, 52'). A cooling gas passage (60', 60'') between the annular main supply channel (52, 52') and the annular main distribution channel (54, 54') is spaced from the cooling gas inlet (44', 44'), so that cooling gas supplied to the cooling gas inlet (44', 44') has to flow through the annular main supply channel (52, 52') through several hearth chambers (12) before it flows through the cooling gas passage (60', 60') into the annular main distribution channel (54, 54').
