The invention relates to a steel-plate descaling device, including several steel-plate surface descalers and several steel-plate side-surface descalers disposed along the direction of a flow line as well as a trolley rail disposed in parallel to one side of the flow line. At least one roller-changing vehicle slides back and forth on the rail. The roller-changing vehicle is provided with a roller-changing mechanism. When the roller-changing vehicle slides to a front side of the steel-plate surface descaler, the roller-changing mechanism extends into the inner part of the steel-plate surface descaler to change the roller. The oxide scale of the steel-plate surface is removed physically, having low pollution and high descaling efficiency without a blind spot, and simultaneously having a high degree of automation in replacing the descaling roller through the roller-changing vehicle, saving both time and effort.

The invention relates to a steel wire descaling device. The device includes one or more first steel wire descalers and one or more second steel wire descalers. A descaling roller for removing an oxide scale from a surface of a steel wire is disposed on each of the first steel wire descaler and the second steel wire descaler. The descaling roller of the first steel wire descaler is disposed inclinedly, the descaling roller of the second steel wire descaler is disposed horizontally. By inclinedly brushing the steel wire by using the first steel wire descaler and flatly brushing the steel wire by using the second steel wire descaler, the combination of flat brushing and inclined brushing allows oxide scales to be from steel wires without a blind spot.

The present invention provides a cell phone frame and a method for manufacturing the same, and relates to the technical field of cell phone accessories. The cell phone frame includes a composite plate, the composite plate encloses a accommodation space for accommodating the cell phone, the composite plate includes a first plate and a second plate, a first side surface of the first plate is provided with striations, the first side surface of the second plate and the first side surface of the first plate are rolled to connect, and the striations of which adjacent ones have a pitch of 0.005 mm to 0.03 mm account for more than 90% of all the striations. According to the cell phone frame provided in the embodiment of the present invention, the first side surface of the first plate is roughened to form striations, which increases the area of the first plate and the second plate subjected to rolling, so that a composite plate produced by combining the first plate and the second plate has a higher bonding strength, thereby ensuring that the cell phone frame is firmer.
