The invention discloses a participating user portrait generation method, device, intelligent conference device and storage medium, which relate to the computer technical field. The method comprises the following steps: personalized data of the conference user is collected, wherein the personalized data is data generated by the conference user in the conference process; the personalized data comprises attribute data and conference information;.a user portrait of the attending user is constructed, and the user portrait is determined according to the personalized data. The technical scheme can solve the technical problem that the user portrait cannot be constructed under the conference scene in the prior art, realize the construction of the user portrait for each participating user under theconference scene, and ensure the accuracy of the user portrait, so as to improve the conference organization efficiency and provide the personalized conference service through the user portrait.

The invention discloses a steel rail induction butt welding and heat treatment method which includes the following steps: locating two steel rails through locating pieces which are installed on the lower portions of center shafts of an induction welding device in a connected mode, enabling jaws of two sets of clamp forceps to clamp the two steel rails respectively and carry out centring, enabling an opening-closing type induction heating coil to be moved to the joint of the two steel rails with the help of auxiliary oil cylinders and wrap the steel rails, enabling two sub-coils to be in contact with electrode structures, enabling a PLC to control the induction heating coil to heat the joint of the steel rails, when the temperature reaches the preset welding temperature of 1200 DEG C to 1430 DEG C, enabling upsetting oil cylinders to exert preset upsetting force to enable the end faces of the two steel rails to be tightly welded together, enabling a protrusion eliminating device to cut welding beading at the joint of the steel rails, enabling the induction heating coil to heat the weld joint of the steel rails again, after the temperature reaches the preset normalizing temperature of 830 DEG C to 950 DEG C, starting an air blasting system to cool the weld joint of the steel rails, and enabling the two sub-coils to be separated through the locating oil cylinders to enable the jaws of the two sets of clamp forceps to be opened to loosen the steel rails. The steel rail induction butt welding and heat treatment method is automatic in operation and high in efficiency.
