摘要： This invention relates to a method and device permitting measurement of oxygen activity in the molten pig iron slag and molten steel slag with high precision. According to the conventional method of measurement depending on the oxygen-concentration cell composed of a one-end-closed tube type solid electrolyte fixed to the tip of the probe, having a contrasting platinum electrode wound around the outer surface thereof, and located directly in the molten slag layer, positioning of the cell in the flowing slag is difficult and insufficient contact of the contrasting electrode with the slag layer is caused on account of thermal contraction of the electroyte resulting from heat of the slag, whereby errors possibly occur in measurement. Unlike the direct measurement of oxygen activity in the slag, this invention provides a method in which a specific metal whose oxygen activity equilibrates with that of the slag when brought into contact with the slag is contained in the same vessel together with the slag and oxygen activity in the specific metal is measured for indirect measurement of oxygen activity in the slag, whereby the problem resulting from insufficient contact of the solid electrolyte with the contrasting electrode can be solved and measurement of oxygen activity in the slag with high precision is ensured.

摘要： An arrangement for use when thermally analyzing and modifying molten metal, by recording solidification data and controlling the structural modification of the molten metal on the basis of such data. The arrangement includes a sampling container made from a material which remains substantially stable at the temperature of the molten metal and which is adapted to receive at least one thermoelement for recording the solidification data. Means are also provided for taking a sample of the molten metal with the aid of the container, and for moving the sample to an area in which substantially the same conditions prevail. In addition, the arrangement includes recording means and means for modifying the structure of the molten metal as required. The sampling container is constructed to allow molten metal to pass thereinto when the container is immersed into the molten metal, and to allow a previous content of the container to be displaced therefrom and replaced with fresh molten metal as a result of relative movement between the container and the molten metal. Means are provided to ensure that a suitable quantity of molten metal is collected during a sampling operation. This may be achieved by providing the sampling container with openings which are closed and exposed by valve means or by some other suitable arrangement.

摘要： In order to reduce the number of inhomogeneous particles distributed through a liquid metal melt, the melt is treated by:
creating a standing wave of ultrasound energy within the melt, whereby the inhomogeneous particles concentrate, and are encouraged to coalesce, at the nodes of the standing wave; and
separating the coalesced particles from the bulk of the liquid melt.

摘要： The invention provides a new immersion head probe for use in apparatus for the determination of the concentration of gas dissolved in a molten metal. Such determinations are needed to facilitate removal of the gas, which can cause bubbles in the solidified metal and subsequent processing difficulties. The apparatus circulates an inert carrier gas through the probe in gas exchange contact with the molten metal to entrain dissolved gas until an equilibrium mixture is obtained; the concentration of the dissolved gas in the mixture then is representative of its concentration in the molten metal. The head consists of a monolithic or integral body of a porous gas-permeable material of sufficient mechanical strength at the temperature of the molten metal and of sufficient porosity, pore size and permeability to permit the necessary gas diffusion in a reasonable period of time. The body of the probe preferably is thin in one direction to minimize the path length for the gas to diffuse therein, and is provided with a carrier gas inlet and outlet suitably spaced apart to ensure that the gas diffuses throughout the body. If the test is to be carried out in a stationary body of molten metal, the probe may be vibrated or the metal may be stirred to increase the probe/metal contact, both decreasing the time required for the gas mixture to reach sufficient equilibrium.
摘要翻译：本发明提供了一种用于测定溶解在熔融金属中的气体浓度的装置中的新型浸没头探针。需要这种测定以便于去除气体，这可能导致固化金属中的气泡和随后的加工困难。该装置使惰性载气通过探针与熔融金属气体交换接触，以夹带溶解的气体直至得到平衡混合物; 混合物中溶解气体的浓度则代表其在熔融金属中的浓度。头部由在熔融金属的温度下具有足够的机械强度并且具有足够的孔隙率，孔径和渗透性的多孔气体可渗透材料的整体或整体组成，以允许在合理的时间段内必需的气体扩散。探针的主体优选地在一个方向上是薄的，以最小化气体在其中扩散的路径长度，并且设置有适当间隔开的载气入口和出口，以确保气体在整个身体中扩散。如果要在熔融金属的固定体中进行试验，探头可能会振动，或者可以搅拌金属以增加探针/金属接触，同时减少气体混合物达到足够平衡所需的时间。

摘要： Un agencement est utilisé pour l'analyse et la modification thermiques de métaux fondus par l'enregistrement de données de solidification et par l'ajustement des modifications structurelles du métal fondu sur la base de ces données. L'agencement comprend un récipient d'échantillonnage fait d'un matériau sensiblement stable à la température du métal fondu et contenant au moins un thermoélément pour enregistrer les données de solidification. Un dispositif permet de prendre un échantillon du métal fondu à l'aide du récipient, et transporte l'échantillon jusqu'à une zone où règnent essentiellement les mêmes conditions. En outre, l'agencement comprend un dispositif d'enregistrement et un dispositif de modification de la structure des métaux fondus, selon les besoins. Le récipient d'échantillonnage est construit de façon à se remplir de métal fondu lorsque le récipient est immergé dans le métal fondu, le contenu antérieur du récipient étant remplacé par du métal fondu frais suite au déplacement relatif du récipient dans le métal fondu. Un dispositif assure la collecte d'une quantité adéquate de métal fondu pendant l'opération d'échantillonnage. Cet objectif peut être atteint en formant des ouvertures dans le récipient fermées et ouvertes par un dispositif de soupape ou par un autre agencement approprié.
