High-speed sequence casting hot-rolling unit for large-section large-weight billet production

Abstract

The invention relates to a high-speed sequence casting hot-rolling unit for large-section large-weight billet production. The high-speed sequence casting hot-rolling unit includes a support frame component, arc-shaped side strips, top strips, arc-shaped support plates, cross strips, first bolts, first nuts, first connection strips, transmission components, rolling components, driving components and cutting components; and each rolling component is arranged between two cross strip combinations, each driving component is arranged between two L-shaped supporting strip combinations and is arrangedabove the corresponding rolling component, the cutting components are arranged between two L-shaped bottom strips and are arranged below the corresponding rolling components, and the upper portions and the lower portions of the rolling components are provided with the transmission components. The high-speed sequence casting hot-rolling unit adopts a detachable structure, facilitates movement andtransportation, has various adjustment functions and is easy to operate and wide in application range.

Description

technical field [0001] The invention relates to a high-speed full-continuous casting hot-rolling unit for the production of large-section and heavy-weight billets. Background technique [0002] The hot rolling unit is a common steel rolling equipment. The thin steel plate blank produced by high-speed continuous casting is input into the hot rolling unit, and the hot rolling unit can process the thin steel blank. Billets with large cross-sections and heavy weights need to be processed in dedicated hot-rolling mills; the existing hot-rolling mills for the production of billets with large cross-sections and heavy weights are fixed in structure and cannot be disassembled, and are inconvenient to move and transport. According to the thickness and hardness of the billet to adjust the feeding speed, cutting stroke, cutting position, etc., the operation is inconvenient and the scope of application is small, which needs further improvement.
