Method for improving corner cracks and middle cracks of plate blank

PendingCN114505461ABelly Stress ReductionReduce cooling intensityTemperature controlTwo temperature
The invention provides a method for improving corner cracks and middle cracks of a plate blank. The method comprises the step of setting two temperature control intervals for the corner temperature of a casting blank. According to the method, the distance between the rollers in the bending section of the casting blank is small, the bulging stress of the casting blank is relatively small, the cooling strength is reduced in the area, the temperature of the bending section of the corner of the casting blank is in a high-temperature section, and corner cracks and middle cracks caused by the influence of bending stress in the bending area are avoided; the cooling strength of the arc-shaped section is increased, so that the temperature of the arc-shaped section entering the straightening area enters the low-temperature area, the middle cracks of the casting blank are effectively reduced, the corners of the casting blank are prevented from entering the brittle area of steel in the straightening area, and corner cracks are avoided; and meanwhile, in cooperation with bending section positioning parameter optimization, straightening area cooling partition and nozzle parameter optimization, the corner temperature of the casting blank is more uniform, corner temperature fluctuation is reduced, and the method has the obvious improvement effect on control over corner cracks and middle cracks of the casting blank.

Inner isolation channel forced accelerated circulation transformer

The invention discloses a forced accelerated circulation transformer with internal isolation channels. The forced accelerated circulation transformer comprises a transformer oil tank and cooling pipes, wherein an iron core winding is arranged in the transformer oil tank. The forced accelerated circulation transformer is characterized in that the distance between the upper part of the iron core winding and an upper cover of the transformer oil tank is less than one fourth of the height of the transformer oil tank, a transverse partition plate extending inwards is arranged on the side wall of the transformer oil tank, the connection position of the transverse partition plate and the side wall of the transformer oil tank is higher than the top of the iron core winding, an encircled plate of which the lower part is spaced apart from the bottom of the transformer oil tank encircles the winding, the upper-end edge of the encircled plate and the inner edge of the transverse partition plate are connected in a crossed way, channels are formed in the space between the encircled plate and the winding, the encircled plate and the transverse partition plate are both hot poor conductors, the two ports of each cooling pipe are respectively arranged above and below the transverse partition plate and are communicated with the interior of the transformer oil tank, and the cooling pipes are integrally in a G shape. By the forced accelerated circulation transformer, heat dissipation area is large, convective circulation speed is fast, the iron core winding is arranged at a low-temperature oil region, and thus, the transformer is ensured to work in a stable temperature environment.
