    Introduction:
    The phenomenon that the volume of solid material increases with temperature is called thermal expansion. The coefficient of thermal expansion is an important indicator for evaluating the quality of carbon materials, which relates to the life of carbon materials. Heat as a cathode lumps used in the lining of aluminum cells. The larger the expansion coefficient, the larger the expansion stress generated during firing of the cell. The more easily the lining is damaged. The anode carbon block used in the upper part of the electrolytic cell has a larger thermal expansion coefficient and is more prone to cracking during use. The larger the carbon block, the greater the current density, the smaller the thermal expansion coefficient of the anode carbon block is required. This is because in the high temperature electrolyzer, the low temperature anode block will produce unbalanced thermal stress under the influence of high temperature, resulting in thermal shock cracking. Experimental observations show that the thermal shock cracking of the anode in addition to the reasons for its mechanical properties, the size of the thermal expansion coefficient is one of the most important reasons. How it works The thermal expansion coefficient of carbon blocks for aluminum electrolysis is determined by the thermal rod expansion device. The sample is placed on a sample holder made of a low-expansion material (quartz glass tube), heated in a furnace, and slightly expanded The amount passed through the quartz glass rod to the thermal rod dilatometer (scale). Manufacturing standards: the implementation of "People's Republic of China Nonferrous Metals Industry Standard" YS / T63.4-2006 and the international standard ISO14420: 2005.
    Instrument use: Used to determine the anode carbon block 300 constant temperature coefficient of thermal expansion. Display: touch screen, the whole process of intelligent experimental data and processing, direct calculation of results, data analysis, real-time operation.
