A heating element heating element respectively, 0Cr25Al5,0Cr27Al7Mo2, Cr20Ni80, SiC, MoSi2, Td, Mo, W, zirconium dioxide, lanthanum chromite heating elements and the like. In particular, high-temperature furnace heating elements, are expensive and limited useful life; zirconia as a high temperature heating element can achieve high temperature of 1800 ℃, but the preparation is difficult, expensive, and poor conductivity at low temperatures, high temperature electric furnace applications limited. The new heating element lanthanum chromite box-type laboratory furnace, low temperature performance to overcome the shortcomings of the lanthanum chromite stick, developed a new dual 1800 ℃ high temperature furnace heating system, provide an important test equipment for the development of materials science. Has very good prospects. Characteristics of the heat generating element a lanthanum chromite lanthanum chromite heating element is lanthanum chromite as a main component, the heating element used in a high temperature oxidizing atmosphere in an electric furnace, the heat generating element lanthanum chromite maximum surface temperature of up to 1900 ℃, furnace temperature can be reach 1800 ℃. Low energy consumption, can be precisely controlled temperatures in the furnace may be in the stability of 1 ℃. Lanthanum chromite heating elements heat up during use, the speed is not too fast, the better and the more uniform heating rate can not be higher than 400 ℃ / h. Furnace temperature below 300 ℃ heating rate should be <4 ℃ / min, in should be 300 ~ 1000 ℃ <5 ℃ / min, the general should be controlled between 200 ~ 300 ℃ / h. Laboratory furnace temperature control system is simple to operate, high precision, good insulation effect, a large temperature range, furnace temperature uniformity, multi-zone, box-type laboratory furnace temperature control system manufacturers, phase trigger, SCR control box industrial furnace, zero trigger, solid state relays, today furnace polycrystalline alumina fiber materials are more double rooms are equipped with air-cooled furnace shell system, fast heating and cooling, the furnace temperature field has a balanced, low surface temperature, elevating the temperature and rate, and energy saving. Temperature control using advanced touch-screen control, the use of PLC control system, with a completely reliable, user experimental data are available, the experimental efficiency. RS232 communication interface with vacuum annealing furnace, Sigma data management software, which can record the history data and the temperature rising curve, correct the temperature deviated error, equipment failure analysis. High temperature laboratory furnace box, box-type laboratory furnace, laboratory furnace provided by Longkou Longkou Furnace experiment.
