To reasonably control the annealing temperature: it is usually the method of solution heat treatment, annealing process, in the course of processing, its temperature should be controlled between 1040 to 1120 ℃, we can through the observation of annealing furnace hole to monitor the situation of the inside, annealing area of the flange should be in a state of incandescent, but should not appear softening drooping.To reasonably control the water vapor in the furnace: on the one hand, it is necessary to check whether the furnace material is dry. If the furnace is installed for the first time, the furnace material must be dried.Two is to check whether there is too much residual water stains for the flange fittings into the furnace, especially for the flange fittings with holes, do not bring water in, otherwise, the atmosphere in the annealing furnace will be destroyed.

To reasonably control the seal of the furnace body: the annealing furnace of the welding flange must be closed and effectively isolated from the outside air. Usually, hydrogen is used as protective gas, and only one exhaust port is passed to ignite the discharged hydrogen.The method of inspection can be used to wipe the joint cracks of the annealing furnace with soapy water to see whether there is a phenomenon of running gas.
