The utility model discloses an iron alloy powder mill which comprises a base, a crushing cavity shell arranged on the base, a built-in crushing cavity, a bearing seat and a main shaft, the main shaft is located in the center of the bearing seat, and a belt pulley is arranged at the end of the outermost side of the main shaft. The crushing cavity is composed of a turbo-type crushing cavity and a plurality of blades, is connected to the main shaft and is driven by the main shaft to rotate at a high speed, and the rotating speed ranges from 2800 r / min to 3000 r / min. One side of the crushing cavity shell is connected with a feeding port, the other side of the crushing cavity shell is connected with a finished product conveying pipe, the feeding port is composed of a feeding net, a plurality of round holes of 10 mm are densely distributed in the feeding net, and only blocky metal materials with the diameter smaller than 10 mm can pass through the feeding net. The product is good in structural sealing performance and free of gaps, and all the components are made of wear-resistant parts and are not prone to damage. And the crushing, grinding and powder making effects are good, and the device is particularly suitable for machining ferrochrome, ferromanganese and ferrosilicon blocky materials.

The utility model discloses a reinforcing mullion structure of an aluminum alloy door and window, which is characterized in that a mullion reinforcing beam is fixed on the outer surface of an existing mullion, and the mullion reinforcing beam and the existing mullion are fastened by using screws. The utility model is used for being installed and fixed on the mullion section bar of the existing aluminum alloy door and window, and has the effects of enhancing the strength and rigidity of the mullion and enhancing the stability and wind resistance of the door and window.

This invention discloses a door leaf sealing structure, an armored door, and a door leaf manufacturing process, belonging to the field of door leaf manufacturing technology. The door leaf includes an inner panel, an outer panel, and aluminum profiles for side frames respectively disposed on both sides of the door leaf. The contact surface between the side frame aluminum profiles and the panel has a concave-convex structure, with multiple independent injection cavities on each convex surface. Each injection cavity has an injection nozzle penetrating the wall of the side frame aluminum profile for injecting sealant into the corresponding cavity. The segmented welding provides structural connection strength, while the cured sealant in each injection cavity provides sealing performance, forming a complementary combination. Each injection cavity is independent, achieving a relay-like renewal of sealing performance. The sealing quality of each side can be quantitatively verified before leaving the factory, and the sealing status can be continuously monitored during use by reading air pressure values, allowing users to visually judge the sealing status without specialized equipment.
