A, radiant tube has the following advantages(1) the radiant tube can assure the controllability of furnace atmosphere;(2) the use of radiant tube can make the furnace temperature control, installation and maintenance convenient, easy to seal;(3) because of lack of muffle tank furnace, enlarged the furnace volume, improve the production capacity;(4) the radiant tube heating ability, high efficiency;(5) the radiant tube saving heat resistant steel.Second, the radiant tube use notice:(1) the use of radiant tube prohibit overheating, overload for a long time use;(2) when the use environment of radiant tube furnace temperature high temperature 400 ℃, shall not be rapid cooling;(3) when the charging and discharging do not touch the radiant tube;(4) the radiant tube in use process should pay special attention to the stove at work, often pay attention to the traffic lights on the control panel is normal, insulation when the traffic lights to exchange a period of time, lest burn radiant tube by control switch failure;(5) the radiant tube in the process of use at any time pay attention to the performance of the instrument, must timely when found that the furnace temperature and the instrument is not normal analysis processing;(6) the use of radiant tube when the environment is more than 100 kw capacity of the furnace, the corresponding each heating zone with best check with ammeter, sedan high temperature furnace every phase should install ammeter, in order to detect the use environment of radiant tube.
