摘要： A method of bonding a protective coating on a wear-exposed surface of a carbon tile comprises: applying onto the wear-exposed surface of the carbon tile at least one layer of a slurry of particulate refractory material suspended in a colloidal and/or inorganic polymeric carrier comprising a dispersion of colloidal particles and/or a solution of inorganic polymeric particles of binding metal oxide; and heat treating the slurry-applied layer(s) to consolidate the particulate refractory material in the binding metal oxide to form the protective coating. A hydrophobic carbon compound having a hydrophilic substituent, such as -OH, -SO3Na or -COOH, is used in the slurry as a bonding agent that bonds the binding metal oxide to the carbon tile by being bonded to the wear-exposed surface of the carbon tile and by having its hydrophilic substituent bonded to the binding metal oxide. Preferably, the protective coating comprises on the layer(s) containing the hydrophobic carbon compound one or more layers of refractory material which are substantially free of any elemental carbon or organic carbon compound.

摘要： A device for the removal of a solidified mineral melt, so called flash, from the spout (3) on a transport channel (1) for a mineral melt (2) in a plant for the production of mineral wool fibers, said device comprising a finger (9) made of a heat resistant material, e.g. of steel, which finger (9) is designed to, by means of a motor (10,11), quickly be moved past and through the melt jet (5) below and adjacent the spout (3) on the melt channel (1) in order to scrape off existing flash material from the melt channel (1). Said device optionally comprises a thermosensor, designed to emit an alarm signal, in case the temperature of the mineral melt at any point falls below a predetermined temperature, and/or a sensor designed to immediately actuate the flash removal finger (9) as soon as a tendency to flash formation appears.

摘要： Said invention relates to methods for the out-of-furnace processing of metal for the iron and steel industry. Said invention makes it possible to expand an active zone of coverage of metal volume by gas or a gas-powder mixture, thereby reducing the time required for obtaining a homogenised composition of metal without increasing the quantity of supplied gas, i.e. to solve the problem of the intensified steel feeling by gas or gas-powder bubbling. The inventive method for feeling steel consists in blowing steel from the bottom by gas or a gas-powder mixture through at least two designed blowdown devices diametrically arranged on the opposite sides of a ladle. The bubbling is carried out alternatively through the devices arranged on the opposite sides of the ladle, a pressure for preventing the flowing of metal in the device which is not used at given moment being maintained therein. The alternative operational time of the blowdown devices is increased proportionally to the increase of steel in the ladle, the volume of supplied gas being unchangeable when the gas or gas-powder mixture supply is switched from one blowdown device to another.
摘要翻译：本发明涉及用于钢铁工业的金属的炉外加工方法。本发明使得可以通过气体或气体 - 粉末混合物扩展金属体积的活性区域，从而减少获得均质化金属组合物所需的时间，而不增加供应气体的量，即解决问题气体或气体粉末起泡增强钢的感觉。用于感觉钢的本发明的方法在于通过气体或气体 - 粉末混合物从底部吹入钢，通过直径布置在钢包的相对侧上的至少两个设计的排放装置。通过设置在钢包的相对侧上的装置交替进行起泡，用于防止装置中金属在给定时刻未被使用的金属流动的压力保持在其中。排放装置的替代操作时间与钢包中的钢的增加成比例地增加，当气体或气体 - 粉末混合物供应从一个排污装置切换到另一个排放装置时，供应气体的体积是不变的。

摘要： An inline degassing apparatus for removing solid solution gases as well as nonmetallic inclusions from molten metal in a degassing container, to which the molten metal is continuously introduced for degassing operation and from which the degassed molten metal is continuously removed. A rotary diffusing device is arranged in the degassing container for generating bubbles of inert gas diffused into the molten metal, thereby entrapping solid solution gases as well as nonmetallic inclusions into the bubbles, which are then floated and separated. Heaters are provided, which extend, in a cantilever fashion, under the rotary diffusing device from a side wall of container at a position adjacent the bottom wall of the container substantially parallel to the bottom wall.

摘要： A method and apparatus are disclosed for injecting vaporizable material, such as a vaporizable waste, into a molten bath. A gas is injected into the molten bath at a rate which is sufficient to cause the gas and the molten bath to form a gaseous dispersion. The gas component of the gaseous dispersion occupies a sufficient fraction of said dispersion to cause a significant portion of the vaporizable material, at a rate at which the vaporizable material is injected into the molten bath, to volatilize, combust or decompose during exposure to said gas component. A vaporizable material, such as a particulate solid or hazardous liquid waste, is injected into the gaseous dispersion at a rate which causes a significant portion of the vaporizable material to volatilize, combust or decompose during exposure of said vaporizable material to the gas component of said gaseous dispersion.
