Internal structure and temperature control method of box-type electric furnace
The box-type electric furnace is a precision and highly functional experimental equipment. The furnace lining is made of special-shaped refractory materials and high-quality insulation materials. Box-type electric furnace bricks are made of corundum mullite, and the insulation layer is made of alumina hollow spheres. 1500 mullite polylight 1300 mullite polylight 1260 ceramic fiber; the distribution of each layer is calculated and optimized to ensure the fire and heat insulation Certain tough ingredients are also a good choice for energy saving. Furnace shell disassembly joint is sealed with silicon rubber, box-type electric furnace mouth is water-cooled to protect the furnace mouth silicon rubber seal, and the furnace mouth is provided with an air inlet and exhaust port. The gas supply system is adjusted by flow (0.16-1.6m3 / h) and pressure monitoring (0.16-1.6kpa). The gas supply source enters the electric furnace through the pressure reducing valve and the gas flow meter. The air inlet is set on the top of the electric furnace, and the exhaust and drainage are set on the bottom of the electric furnace. The thermocouple adopts B graduation number and is installed on the top of the furnace. The furnace roof is removable for maintenance. The technical requirements of the furnace body building furnace meet the industrial furnace building project construction and acceptance specifications.
The temperature control instrument adopts intelligent instrument temperature control, PID automatic adjustment, with over-temperature, segmented alarm protection function, and temperature compensation function, the furnace temperature is consistent with the instrument display temperature. 40-segment programmable. There are voltmeters, ammeters, power air switches, temperature control instruments, etc. on the panel of the control cabinet, and there are audible and visual alarm devices such as overtemperature and broken couple. Temperature control mode: thyristor phase-shifting voltage regulation, with automatic current limiting, over-current, over-heating and other protection functions. The reliable and highly intelligent temperature control method of box-type electric furnaces and excellent thermal insulation materials, computer optimized design and various compensation functions are all in one. It provides technology and equipment for obtaining accurate experimental results and performing highly professional experimental testing. Protection.
