(2) Operation operation: When using a jacket device, the pressure to slowly heat up. To advance through the 0.1MP pressure, Shenyang enamel reactor manufacturers, holding a quarter of an hour, and then slowly introduced into the vapor pressure of the operation, Qinhuangdao enamel reactor manufacturers, if conditions permit, according to the actual situation of the unit, enamel reactor manufacturers, to identify suitable heating and cooling curve, the general control 3 ℃ / min or less. Equipment operation, should pay attention to the flange, then set the seal case manholes and packing boxes, such as find a leak should take immediate measures; technological factors during thermal cracking reactor impact a lot of welding, such as joint form of standardized, pre-heating temperature, structural rigidity and workpiece clamping conditions and so have some influence on the ability to weld thermal cracking. Welding technology and specifications. The use of high current, fast welding, single welding, linear motion shall forward, it tends to cause stress welding process measures will lead to thermal cracking. Therefore, when conditions permit, should try to use small current, multi-layer welding, in order to reduce the tendency of hot cracking. Welding structural rigidity larger parts, often used method of preheating.
