The method has simple operation, simplifies production procedure, shortens production cycle, reduces the transportation and transferring of the steel plate in the middle procedure, saves energy consumption, reduces the increase of unscheduled quantity and can achieve good plate shape; and practices prove that the performance of the steel plate is unchanged, meets various standards and has obvious economical benefit.

The invention relates to equipment for producing tempering glass, in particular to a curved surface tempering glass blowing device which comprises a lower air flue, a lower wind box, an upper wind box, an upper air flue, a lower wind box lifting device and an upper wind box lifting device. The curved surface tempering glass blowing device is characterized in that surfaces of the lower wind box and the upper wind box, which are back-to-back, are respectively provided with a connecting hole connected with the upper air flue and the lower air flue; and surfaces of the lower wind box and the upper wind box, which mutually correspond, are air-out surfaces which are provided with at least 100 air outlets. The air outlets are respectively provided with a blowing nozzle. The invention has the remarkable advantages that: the air-out surfaces avoid reflective exhaust of air blowing to glass so as to realize four-side exhaust to ensure that the cooling temperature on the surface of the glass is uniform, and the glass tempering quality is improved; smooth wind path, good blowing effect and high wind energy utilization ratio are achieved; and the curved surface tempering glass blowing device has reasonable structure, low cost, convenient maintenance and long service life.

The invention discloses a continuous quenching cooing system for strip metal, which comprises a cooling tank for containing the cooling liquid and a cooling liquid circulation mechanism, wherein the side wall of the cooling tank is provided with a material outlet and a material inlet for the strip metal to pass horizontally; and a strip metal straightening mechanism on the same line as the material outlet and material inlet is arranged in the cooling tank. The system disclosed by the invention cools the strip metal by use of the cooling liquid in the cooling tank, and ensures that the strip metal is not bent through the straightening mechanism; due to the lubrication of the cooling liquid, scratch is not left even if friction exists between the straightening mechanism and the strip metal; and moreover, as the entire section of the saw blade is immersed in the cooling liquid, the cooling temperature is uniform, and the strip metal can not deform.
