Process for online cut-to-length cutting production of continuous casting slabs for heavy plate mill

A technology of cut-to-length cutting and production technology, which is applied in the field of on-line cut-to-length cutting production technology of continuous casting slabs for thick plate rolling mills, and can solve the problem of lack of flexibility between the long billet cut-to-length cutting line and the main rolling line, and the artificial cold-loading of slabs. Cutting, unsatisfactory and other problems, to avoid low cutting length accuracy, flexible production, and reduce transportation costs

Problems solved by technology

The cut-to-length cutting line is connected with the slab charging roller table through a traverse device, and the deburring machine is installed on the heating furnace charging roller table. If the deburring machine fails or the deburring effect is not good, the slab needs to be processed offline, which affects Slab charging and main rolling line production, this arrangement makes long billet cut-to-length cutting line and main rolling line lack of flexibility, which is not conducive to production
The maximum length of the long billet in the plant is limited to 9m, so that the ratio of cutting one long billet into three cut-to-length billets will decrease, which will help improve the capacity of the secondary cutting line, but cannot meet the requirements of the 1.8 million-ton continuous production capacity of the double-stand thick plate rolling mill. Demand for cast slabs, a large number of cold-loaded slabs still need to be manually cut off-line

Embodiment Construction

[0046] see figure 1 , figure 2 , the long slab produced by the slab continuous casting machine in the steelmaking plant is transported to the receiving roller table in the slab receiving span of the raw material warehouse of the thick plate factory through the roller table, where the long slab 1 is received. After completing the identity verification of long slabs, the long slabs without contracts are stored offline 2, and the offline slabs will be put online after the contract is matched 3. The long slab with the contract is directly sent to the slab receiving roller table of the secondary cutting line in the cutting span through the slab transfer machine cross-span 4. The long billet is transported to the centering roller table for width centering5. After centering, the long billet is transported to the length measuring and printing roller table to measure the length and temperature of the long billet6, and then carry out marking and printing on the billet to length acco...

Abstract

The invention relates to a process for the online cut-to-length cutting production of continuous casting slabs for a heavy plate mill. The process comprises the following steps: long slab reception; span-transversing; width centering; length and temperature measurement; cut-to-length slab mark spraying; cut-to-length cutting; cutting burr removing; unloading; and storing, wherein three pairs of flame cutting machines are distributed in a series-connection manner on the cutting line. Accordingly, the process of the invention is capable of simultaneously cutting two long slabs on-line accordingto various requirements for cut-to-length cutting; the process of the invention has the advantages of high production efficiency and small equipment occupied area; the cut-to-length cutting procedurehas little impact on the main production line for continuous casting and heavy-plate milling; the process is capable of carrying out the mixed cutting process on cold and hot slabs, thus being favoring for the hot-loading and hot-feeding processes of slabs. Accordingly, the process of the invention is widely applicable to the online cut-to-length cutting production of the continuous casting slabsfor the heavy plate plant.

Description

technical field [0001] The invention relates to an on-line fixed-length cutting production process for a continuous casting slab used in a thick plate rolling mill. Through the continuous production method, the continuous casting long slab input by the steel plant through the roller table is cut into the fixed-length slab required by the thick plate rolling mill, which shortens the storage time of the slab and realizes the hot charging of the continuous casting slab. The continuous casting slabs of different temperatures and specifications are mixed with high-efficiency cut-to-length production process. Background technique [0002] With the advancement of continuous casting technology, continuous casting slabs are mainly used as raw materials for heavy plate factories. When continuous casting machines cast slabs, the cutting of the length of the slabs must match the casting speed of the continuous casting machine. The length is usually in the range of 6-10m. When the slab ...
