Embodiment 1

[0050] A method for continuous heat treatment of materials, the steps are as follows:

[0051] (1) Install the rotary device and the feeding device, adjust the distance between the two adjustment blocks on the blanking adjustment module to 9mm, pour the silicon nitride powder into the collection barrel, and adjust the furnace body so that the angle between the rotary device and the horizontal plane is 0.5 Spend.

[0052] (2) Raise the temperature of the tube furnace to 1250°C and keep it at a constant temperature, start the deceleration motor, and control its speed at 1.0r / min;

[0053] (3) Put the material guide plate of the feeding device on the feeding port of the left support cylinder, the feeding device starts to work, and the silicon nitride powder continuously enters the rotary device.

[0054] According to calculations, after the silicon nitride powder enters the left support cylinder from the feed port, it takes about 184 minutes to be discharged from the discharge p...

Embodiment 2

[0057] A method for continuous heat treatment of materials, the steps are as follows:

The invention further relates to a method for material continuous thermal treatment.

Description

technical field [0001] The invention relates to the high-temperature heat treatment electric furnace industry, in particular to a device and method for continuous heat treatment of materials. Background technique [0002] Rotary furnace is a kind of thermal equipment used for calcining, roasting and drying granular or powdery materials. It is widely used in building materials, metallurgy, chemical industry, environmental protection, new materials and other fields. In the building materials industry, the rotary furnace is the main equipment for the production of cement clinker and the key equipment for the production of clay ceramsite and limestone; in the production of refractory materials, the raw materials calcined by the rotary kiln are more stable, stronger and more formable. In the beneficiation process, the rotary furnace is widely used in the drying of slag. The rotary furnace is used to magnetize and roast the lean iron ore, so that the original weak magnetism of the...
