The invention discloses a flexible display screen folding and unfolding device and an electronic device, and relates to the technical field of electronic equipment.The flexible display screen folding and unfolding device comprises a first support, a second support and a driving mechanism, and the first support is slidably connected with the second support; the driving mechanism is arranged on the first support and the second support and used for driving the first support and the second support to slide relatively, the driving mechanism comprises a first driving assembly and a second driving assembly, and the first driving assembly is fixedly arranged on the first support and connected with the second support; the second driving assembly is fixedly arranged on the second support and connected with the first support, so that the second driving assembly and the first support have a more stable contact state and are not prone to deviation or separation under the dynamic load, continuous transmission of force is kept, vibration and noise generated by unstable interaction force can be reduced, and the service life of the device is prolonged. And the relative movement of the first bracket and the second bracket can be ensured to be more stable and smoother.

The utility model relates to the technical field of air brick, disclose a kind of high-performance monolithic air brick, including air brick core, seat brick and sintered protective sleeve, the cavity for accommodating air brick core is equipped in protective sleeve inside, and air brick core is located in the cavity of protective sleeve, seat brick is casted and formed in the outside of protective sleeve, and the same end of protective sleeve and air brick core is extended to the outside of seat brick, and the same end of protective sleeve and air brick core is wrapped in the inside of seat brick;Ventilation component is provided on seat brick, and ventilation component is used to ventilate the end face of air brick core located in the inside of seat brick one end.The utility model can slow down the speed of seat brick being eroded by molten steel.

A crucible assembly and a thermal field assembly, the crucible assembly comprising a crucible holder; a crucible slope which is arranged on the crucible holder, the crucible slope having a crucible mounting cavity that gradually expands from the crucible holder in a direction away from the crucible holder; and a crucible which is arranged in the crucible mounting cavity, an outer side surface of the crucible being an outer side surface that gradually increases from the crucible holder in the direction away from the crucible holder, the outer side surface being arranged opposite an inner side surface of the crucible mounting cavity, and the crucible slope having a softening temperature higher than that of the crucible. According to the above solution, the crucible slope and the crucible can easily be separated, thereby avoiding damage to the crucible slope and improving the production safety.
