Description

TECHNICAL FIELD

[0001] The present application relates to the field of mold stripping, more particularly to a hydraulic ring main unit foundation steel mold. BACKGROUND

[0002] Stripping refers to a series of operations for stripping the ingot from the ingot mold. The time from the completion of the steel pouring to the stripping is the ingot transfer time, which is the time from the completion of the pouring of the last ingot (the lower pouring tray) of a ladle to the start of the stripping (the stripping of the cap) of the first ingot. For killed steel ingots, the entire ingot body needs to be solidified before the stripping of the holding cap can be started. For semi-killed steel ingots and boiling steel ingots, the solidified layer needs to reach a certain thickness before the stripping can be started.

[0003] The transfer time of various ingots in the mold depends on the solidification speed or the complete solidification time of the ingot, which can be determined according to experience or experiments. Small steel plants producing ingots with a single weight of less than 3t generally use the stripping (ingot) clamp or lifting device attached to the general bridge crane to complete the stripping operation. For large ingots produced by the car pouring method, the stripping (ingot) machine is used in the stripping bay.

[0004] The traditional steel mold stripping method is complicated, and it takes a lot of labor and time to disassemble and assemble the mold, which is slow and inefficient. It is difficult for the product to be stripped from the core mold when the product is stripped from the mold, which causes damage to the product quality and the performance of the crane equipment used for lifting the product, and safety accidents of the tooling equipment.
