摘要： A system for wirelessly obtaining a measurement of a characteristic of a molten metal is disclosed. The system includes a contact block configured to be operatively coupled to a first end of a substantially hollow lance holder. The contact block is detachably and electrically coupled to and receives analog signals from a measurement sensor. The contact block converts the received analog signals into ultrasonic signals and transmits the ultrasonic signals through the hollow of the lance holder. A receiver block is configured to be operatively coupled to a second end of the lance holder. The second end is opposite the first end of the lance holder. The receiver block receives the ultrasonic signals from the contact block and converts the received ultrasonic signals into a digital voltage signal.

摘要： A thermocouple lance for measuring temperatures in molten metals has a protective sheath of multi-layered structure that makes it possible to improve the life expectancy of repetitive measuring services. The thermocouple lance comprises a protective sheath with one closed end and one open end wherein porous heat-resisting ceramic filler is compacted. Embedded in the filler is a pair of W—Re alloy wires dissimilar in their composition from each other. The protective sheath has the layered structure made from the cermet layers each having a molybdenum matrix and other layers of at least one selected from the class consisting of C, MgO, CaO, Al2O3 and ZrO2, both of which layers are overlapped each other in alternate layer. At least the outermost shell layer of the protective sheath is made of a cermet layer composed of any one of Mo—ZrN, Mo—ZrB2, Mo—ZrO2, Mo—ZrC and composite thereof.

摘要： This ceramic sheath type thermocouple has a long service life, an improved temperature measuring responsibility and an improved temperature measuring precision, and enables repetitive use. The ceramic sheath type thermocouple has its protective tube 1 formed of a heat resisting ceramics selected from silicon nitride, sialon and silicon carbide. In the protective tube 1 are installed a pair of W--Re wires that are connected to form a joint portion constituting a temperature measuring point 5. A filler made of Si.sub.3 N.sub.4 reaction-sintered ceramics is loaded into the front end portion of the protective tube to enclose the W--Re wires. Another filler made of SiC whisker with a heat conductivity smaller than that of the filler of the front end portion is loaded into the rear portion of the protective tube. An inert gas is sealed in the protective tube. Alternatively, the temperature measuring portion may be formed by exposing from the front end portion of the protective tube the joint portion where the ends of the W--Re wires are connected. The temperature measuring portion is coated with a cover film that is made of silicon carbide, silicon nitride or a composite of these, all having excellent heat resisting and corrosion resisting properties.

摘要： Apparatus for automatically controlling a bath sensing operation in a steelmaking process is disclosed. A sensor, housed within a probe, is movable in relation to the probe. A first mechanism is connected to the probe to move it relative to a vessel. A second mechanism is connected to the sensor to move it relative to the probe. An automatic control circuit prevents the sensing operation from commencing unless good electrical contact is made between the sensor and recorders and a flow of protective gas is established about the sensor. If these two conditions are satisfied, the automatic control circuit causes the first mechanism to lower the probe to a predetermined depth within the vessel, and then allows the second mechanism to extend the sensor from the probe to a predetermined depth within the bath. After bath parameters such as oxygen content, temperature, and carbon content have been sensed and recorded, or after a maximum duration of time, whichever occurs first, the control circuit reverses the operation of the first and second mechanisms to retract the sensor into the probe and withdraw the probe from the vessel.
摘要翻译： 公开了一种用于在炼钢过程中自动控制浴传感操作的装置。 容纳在探头内的传感器可相对于探头移动。 第一机构连接到探针以相对于血管移动。 第二机构连接到传感器以相对于探头移动。 除非在传感器和记录器之间进行良好的电接触，并且围绕传感器建立保护气体流，否则自动控制电路可以防止感测操作开始。 如果满足这两个条件，则自动控制电路使得第一机构将探针降低到容器内的预定深度，然后允许第二机构将传感器从探针延伸到浴内的预定深度。 在诸如氧含量，温度和碳含量的浴参数已经被感测和记录之后，或者在最大持续时间之后（以先发生者为准），控制电路反转第一和第二机构的操作以将传感器缩回到探头 并从血管中取出探针。
