LGK-S107 Analog Heat Source Instrument Overview: LGK-S107 analog heat source instrument (heating tool) is independently developed and designed by Wuhan CenterRise M&C CO.,. This instrument is a heating and testing equipment used to test the performance of the couple installed in the mold in continuous casting machine. After the installation of the mold breakout forecast couple is completed, the analog heat source instrument is used to test these couples before they go online. After the thermocouple is connected to the mold thermocouple detector, the current temperature of each thermocouple point will be displayed. By using our heating device to heat the copper plate point of each thermocouple at a fixed point, the thermocouple will have a synchronous temperature rise and then we can observe the temperature rise curve of the same column of temperature points to see whether the temperature measurement consistency of the column of couples is consistent, so as to judge the overall status of couples installed in the mold. If an abnormal point occurs, it needs to be repaired and replaced, so as to ensure the stable operation of the mold breakout prediction system. The working principle: The heating tool generates high heat by 220v alternating current and the electric heating element. The heat is transmitted to the copper plate of the mold through the copper head to simulate the heat source of molten steel, so that the thermocouples of the mold can sense the temperature change to achieve the purpose of calibrating the temperature measurement system. The composition: Walking trolley mechanism Preloader Pure copper heating contacts PID thermostat High power heating tube high power driver The parameters: Power supply: AC220V 50Hz Total power: 2200W Single point power: 300W Temperature control accuracy: 1�°C Temperature control range: 0�°C-500�°C Common temperature range: 25�°C-300�°C Heating points: 3 (points can be customized) Heating method: heating tube heating Heating contact material: copper
CuW75 Customized Tungsten Copper Alloy Heat Sinks WCu Spreader For LED Industry The CuW75 tungsten copper alloy is used extensively in thermal mounting plates, heat sinks, chip carriers, flanges, and frames for high-power electronic devices. As a tungsten copper material, it's a composite, so both the thermal advantages of copper and the very low expansion characteristics of tungsten can be utilized. The combination of tungsten & copper materials results in thermal expansion characteristics similar to those of silicone carbide, aluminum oxide, and beryllium oxide, used as chips and substrates. Because of tungsten copperâ??s thermal conductivity and expansion characteristics, Tungsten copper alloy works well in densely packed circuits. The thermal conductivity and thermal expansion characteristics of the semiconductor and the base plate must be optimally harmonized to avoid undesired distortions to the semiconductor. The better harmonized the properties are, the better the semiconductor module is to withstand soldering processes involved during manufacture and the temperature cycles that occur during operation.

Bentonite is a high swelling clay mineral whose name was derived from the location of the first commercial deposits mined at fort benton, wyoming u. S. A. Mineralogically, bentonite mainly consists of montmorillonite in combination with various mineral impurities such as feldspars, calcite, silica, etc. Montmorillonite belongs to the smectite group of clays which also include similar behaving minerals such as beidellite, saponite and hectorite. Geologically bentonites are mainly of volcanic origin, the majority of commercial deposits were formed by the hydrolysis or metamorphism of volcanic rock or ash and are almostly found in everywhere in world. The structure of montmorillonite is fundamentally a three layer structure with an octahedral aluminium hydroxyl sheet sandwiched between two layers of silicon- oxygen tetrahedra. However, the aluminium atoms are partially replaced by the substitution of either magnesium or iron atoms, thereby creating a charge deficiency within the unit structure. This results in a small negative charge on the basal plane of silica tetrahedra which is balanced by absorption of exchangeable cations between adjacent platelets. In natural montmorillonite, these cations are usually calcium, sodium or magnesium according to the formations of bentonite. Specification -welldry activated clay (montmorillonite clay, bentonite clay), 100% pure clay desiccant without any calcium chloride. In p.P. Woven bags of 25 kgs / 50kgs /1000 kgs net Kept in dry and ventilating place, prevent from rain and moisture when storage; if agglomerated, please crush and make it into solution, and its effect will be the same.
