In one embodiment, a system (100) temperature control apparatus (105) controls the temperature of metal object's (106) surface (112) to an application temperature below the Leidenfrost temperature point of an alkali metal hydroxide aqueous conditioning solution.

    Abstract: This process for the secondary descaling of running metal strips, especially made of steel, while being hot-rolled, by spraying water onto their surface using spray rails having nozzles supplied with pressurized water, is characterized in that the nozzles are supplied at low hydraulic pressure, not exceeding 30 bar (preferably below 10 bar, but without going below 4 bar), and in that, for the purpose of providing a thermal effect of the water sprayed onto the surface to be descaled quantitatively similar to the thermal effect obtained with the usual known method of secondary descaling at high pressure, namely a cooling of the strip which reduces its surface temperature to around 600°C, said nozzles are adjusted in order that the heat flux density extracted from the strip (HF) resulting from the cooling of its surface by the sprayed water is similar to that produced with said known high-pressure practice. The invention applies to any secondary descaling, both upstream of the finisher and upstream of the roughing device of a rolling mill train. It provides an immediate operational response to the reduction of the descaling costs, that is to say compatible with a restructuring of existing industrial equipment, therefore without necessarily involving the reinstallation of complete new equipment.

    Abstract: An automatic control system is provided for acid concentration in an aluminum strip cleaning line wherein an aluminum strip is contacted with an acid solution while passing through an acid cleaning bath and the concentration of the acid in the bath is adjusted by adding either concentrated acid or water to the bath. A conductivity probe provides a signal for the free acid concentration of the bath and an on-line process titrator periodically provides a second signal indicative of the actual free acid concentration and the total acid concentration. These first and second signals are used to obtain a corrected value for free acid concentration. The bath acid concentration is then adjusted as required based on the corrected specific conductivity value.

    Abstract: Methods for deoxidizing metallic surfaces are disclosed. Such a method may include contacting a surface of a metal strip (102) with one or more chemical solutions until a potential drop across a thickness of the metal strip (102) is less than a pre-selected value. To process a metal strip (102) such that it may be suitable for fabrication of a bipolar plate for use in a fuel cell, the metal strip (102) may be processed until the potential drop is less than about 15 mV. A surface of the metal strip (102) may be contacted for a first period of time with a first chemical solution having a pH of between 10 and 14. Thereafter, the surface may be contacted for a second period of time with a second chemical solution having a pH of between 1 and 3. A conductive organic coating may then be applied to the surface. Such methods are particularly suitable for use in connection with a coil coating process.

    Abstract: The invention relates to a method for scouring or cleaning rolled steel strip which, in the form of loops, is moved through several scouring or cleaning containers that are arranged in the treatment line, and at least one side of the strip is subjected to the action of the scouring medium or cleaning medium supplied by squirting or spraying units. Said units can be switched on or off and/or their spray width can be adjusted and/or they can be operated with a controllable squirting or spraying pressure and/or volume flow. The aim of the invention is to substantially reduce the space requirements and, at the same time, to be able to attain a precise adaptation to the respective scouring task or cleaning task with the objective of reducing scouring time or cleaning time and to attain an improved scouring or cleaning effect over the width of the strip. To these ends, the strip, before being inserted into the scouring or cleaning treatment part, is diverted from the horizontal strip running plane into a vertical strip running plane arranged in an edgewise manner and is diverted into its normal horizontal strip running plane after exiting the scouring or cleaning treatment part.
