    摘要: The invention discloses a device for continuously measuring the flow rate of steel melt near surface thereof, wherein the device comprises a flow rate detecting rod (18) and a deflection means (B) for the flow rate detecting rod, wherein the flow rate detecting rod (18) comprises a refractory material tube at one end and a stainless steel rod at the other end, and the stainless steel rod is fittedly connected with the refractory material tube. The flow rate detecting rod (18) comprises a refractory material of a single compound or a composite of two or more compounds. The flow rate detecting rod (18) has a length of 10-100cm and a diameter of 5-50mm. The deflection means (B) for the flow rate detecting rod comprises a fastening screw (27) for the flow rate detecting rod, and the flow rate detecting rod (18) is fixed to the deflection means (B) for the flow rate detecting rod by using the fastening screw (27) for the flow rate detecting rod. The present invention also provides a method for continuously measuring the flow rate of steel melt near surface thereof, comprising the steps of determining the barycenter, the rotational pivot and the acting point of an impact force on the flow rate detecting rod; calculating the distance between the rotational pivot and the barycenter, as well as the distance between the rotational pivot and the acting point of the impact force; measuring the gravity value of the flow rate detecting rod; inserting the refractory flow rate detecting rod into the steel melt to obtain a rotational angle and an insertion depth; and consequently calculating the continuous variation of the flow rate of the steel melt.

    摘要: A device is provided for measuring metal inclusions comprising a receptacle for holding a sample of molten metal, with this receptacle having insulated side walls and a bottom wall provided with an exit opening. A ceramic filter element for collecting inclusions from the molten metal is positioned within the exit opening and is bonded to the top face of a solid refractory or metal annular support ring with a portion of the support ring top face extending laterally beyond the filter element and engaging the bottom face of the bottom wall of the receptacle around the opening. The filter element and support ring assembly is held in place by a detachable retaining means which is adapted to securely hold the support ring in leak-tight engagement against the receptacle bottom wall with the filter element positioned in the exit opening.

    摘要: A method is disclosed for improving the making of metals such as steel and copper by specially using a gas measurement system to analyze molten metals for gas, particularly H2 content, and to controlling the metal making process based on these values. The preferred gas analyzer comprises a hollow probe and an analyzer wherein the probe is immersed in the molten metal and a carrier gas containing a reducing gas such as CO is cycled through the probe and analyzer. The carrier gas entrains gases in the probe and this gas mixture is electronically compared with a reference value to provide a measurement of the gases in the molten metal and the process is controlled based on the analyzer results. Another important use of the gas analyzer is in molten metal degassing operations such as used in the steel industry.
