The application discloses a kind of based on crystallizer electromagnetic stirring bar surface inclusion control method, belong to steel metallurgy continuous casting and rolling technical field.The method first establishes the finite element model of multiple pass rolling process from continuous casting billet to target bar, and using node reverse tracking technology, the specific area of continuous casting billet that has decisive influence on bar surface quality is determined as target clean control area.Subsequently, the multi-physics field coupling model of flow, solidification and inclusion movement in crystallizer is constructed, and the installation position of crystallizer electromagnetic stirrer that can make the inclusion capture probability in target clean control area be reduced to the lowest is determined as the optimal process position by simulation analysis.Finally, electromagnetic stirrer is installed according to this position in actual continuous casting production and production is carried out.The application realizes accurate targeted control of cleanliness of key area of continuous casting billet from the requirement of final product quality, and significantly improves the surface quality and service performance of high fatigue requirement steel such as bearing steel.

The invention discloses a low-invasion tunnel forced centering support and a mounting method thereof, and belongs to the technical field of tunnel safety monitoring, the low-invasion tunnel forced centering support comprises two right-angle connecting plates, two supporting rods, a top plate and a forced centering base, and each right-angle connecting plate is composed of a first vertical plate and a second vertical plate which are perpendicular to each other; when the device is installed at the vertical corner of the side wall of the vehicle avoiding hole and the side wall of the main hole, the first vertical plate is attached to the side wall of the main hole, one part of the second vertical plate is attached to the side wall of the vehicle avoiding hole, and the other part of the second vertical plate extends out of the side wall of the main hole. A second vertical plate of the right-angle connecting plate above is horizontally connected with a top plate, part of the top plate is located in the vehicle avoiding hole, part of the top plate protrudes out of the side wall of the main hole, and a forced centering base is installed on the top plate and used for installing a measuring instrument and automatically monitoring a plurality of tunnel sections in front and back areas of a corner; the two supporting rods are arranged between the two sides of the top plate and the right-angle connecting plates below the top plate and used for improving the bending resistance and vibration resistance of the top plate, and the stability of the forced centering support is guaranteed.

The utility model provides a corrosion-resistant composite coating fastener which comprises a fastening assembly, an elastic adjusting assembly is arranged in the fastening assembly, a fine adjustment assembly is arranged in the fastening assembly, a compensation limiting assembly is installed on the top of the fine adjustment assembly, and a wedge-shaped positioning assembly is installed on the top of the compensation limiting assembly. The utility model provides a corrosion-resistant composite coating fastener. The corrosion-resistant composite coating fastener is used in cooperation with a compensation limiting assembly and a wedge-shaped positioning assembly. The wedge-shaped positioning assembly generates extrusion force perpendicular to an inclined plane when the fastening assembly is stressed according to the inclined plane self-locking principle. The compensation limiting assembly can dynamically compensate infinitesimal displacement caused by factors such as vibration and temperature change. Meanwhile, the elastic adjusting assembly arranged at the bottom is used in cooperation with the fine adjustment assembly, and the elastic adjusting assembly can adapt to position deviation within a certain range through elastic deformation of the elastic adjusting assembly; and the fine adjustment assembly provides a fine adjustment function.

The utility model discloses a flexible light photovoltaic module rigid auxiliary reinforcing structure, which comprises a plurality of long-edge reinforcing ribs and a plurality of short-edge reinforcing ribs, a module plugboard is arranged on one side of a top plate, a plurality of slots are arranged on the module plugboard, a module fixing mounting plate is arranged at the bottom of the module plugboard, and the long-edge reinforcing ribs and the short-edge reinforcing ribs are arranged on the top plate. A connecting plate is arranged between the two clamping plates, inserting blocks are arranged at the two ends of the connecting plate respectively, inserting holes are formed in the inserting blocks respectively, bolts can be installed in the inserting holes, and efficient and reliable right-angle connection between the long-edge reinforcing ribs and the short-edge reinforcing ribs of the assembly is achieved. The short-side reinforcing ribs are accurately inserted into the slots in the long-side reinforcing ribs through the insertion blocks arranged on the two sides, and are matched with a quick locking mechanism of the bolts and the insertion holes, so that the connection rigidity is remarkably improved, convenient mounting and dismounting operations are realized, in addition, the reinforcing ribs are made of polyurethane materials, the structural strength is ensured, and the service life of the reinforcing ribs is prolonged. And the lightweight design of the assembly is effectively realized.
