The invention aims to provide a camel billet rolling method for producing a steel plate with a thickness of 6mm and a limit specification by a medium plate, which adopts a method of carrying out camel billet heating and discharging and splitting to finish rolling by a conventional billet with the limit length specification backed on, can overcome the problem that the specification of the billet is limited and the billet cannot be suitable for the normal billet loading size of a heating furnace, and realizes the production of the steel plate with the limit thin specification by using the existing thick plate part production equipment.
In order to achieve the purpose, the invention adopts the following technical scheme:
a camel blank rolling method for producing a 6mm thick steel plate with a limit specification by a medium plate adopts a blank B with a conventional production specification to back a steel plate blank A with the limit specification, and simultaneously, the blank B is sent into a heating furnace to be heated, and is separated by a separator to be rolled respectively after being discharged, and the method specifically comprises the following steps:
two blanks A and B of the back blanks are mutually backed, wherein the length specification of the back blank B arranged below is more than or equal to 3 mm; the blank A to be backed which is arranged on the upper part is used for rolling a steel plate with the thickness of 6mm and the limit specification, and the length specification of the blank A is less than 2500 mm;
after the steelmaking data of the blank A and the blank B are transmitted to the thick plate part heating furnace, post personnel select the blank B to back the blank A on a PDI information picture, and the blank B information and the real object are normally and automatically charged; deleting the data of the blank A in the primary computer, and manually inputting the charging data of the blank A in the tertiary computer;
and during tapping, automatically finishing tapping operation by the blank B against the blank A, separating the blank B from the blank A, manually downloading PDI data of the blank A in a secondary picture, calculating a pass rule by a secondary computer, and then sending the pass rule to a primary computer for rolling, thus finishing rolling of the blank A and the blank B in sequence.
Compared with the prior art, the invention has the beneficial effects that:
a method for rolling a camel blank of a 6mm thick steel plate with a limit specification by a medium plate is characterized in that a conventional blank is used for carrying a camel blank with a limit length specification, and the camel blank is heated and discharged to finish rolling, so that the problem that the blank specification is limited and the blank cannot be suitable for the normal blank loading size of a heating furnace can be solved, the rolling risk and the damage to equipment existing in the process of rolling the steel plate with a limit thin specification are avoided, and the production of the steel plate with the limit thin specification by using the existing thick plate part production equipment is realized.

Detailed Description
Embodiments of the invention are further described below with reference to the accompanying drawings:
a camel blank rolling method for producing a 6mm thick steel plate with a limit specification by a medium plate adopts a blank B with a conventional production specification to back a steel plate blank A with the limit specification, and simultaneously, the blank B is sent into a heating furnace to be heated, and is separated by a separator to be rolled respectively after being discharged, and the method specifically comprises the following steps:
two blanks A and B of the back blanks are mutually backed, wherein the length specification of the back blank B arranged below is more than or equal to 3 mm; the blank A to be backed which is arranged on the upper part is used for rolling a steel plate with the thickness of 6mm and the limit specification, and the length specification of the blank A is less than 2500 mm;
after the steelmaking data of the blank A and the blank B are transmitted to the thick plate part heating furnace, post personnel select the blank B to back the blank A on a PDI information picture, and the blank B information and the real object are normally and automatically charged; when incoming materials are centered in a furnace charging channel for operation, PDI information data of the materials A and B are transmitted in the previous working procedure, so that the data of the blank A needs to be deleted in a primary computer; and (3) manually inputting the charging data of the blank A in a three-stage computer, wherein the operation is to additionally record the data of the A in a steel charging production actual result in a production MES system and keep the consistency of the actual product and the information.
And during tapping, automatically finishing tapping operation by the blank B against the blank A, separating the blank B from the blank A, manually downloading PDI data of the blank A in a secondary picture, calculating a pass rule by a secondary computer, and then sending the pass rule to a primary computer for rolling, thus finishing rolling of the blank A and the blank B in sequence.
Example 1:
the billet specifications and rolling target specifications of the billet A and the billet B are shown in the table 1:
table 1:
| blank material | Specification (mm) | Rolling target Specification (mm) | Rolling situation |
| Upper blank to be backed (A) | 110×1520×2500 | 6.1×1800×46500 | Success of rolling |
| Lower back blank (B) | 200×1450×3500 | 10×2600×34000 | Success of rolling |
The blank B is a blank with a conventional production specification and can be suitable for the normal blank loading size of a heating furnace; the blank A is used for rolling a 6mm thick steel plate with a limit specification, the length specification of the blank A is 2500mm, and the blank A cannot be suitable for the normal blank loading size of a heating furnace. And placing the blank B as a back blank at the lower part, placing the blank A as a blank to be backed on the blank B, placing the blank B on the back of the blank A, and simultaneously sending the blank B into a heating furnace for heating.
The rolling plan sequence mode is a front and back arrangement principle (namely arranging and producing a blank A specification and then connecting a blank B specification; arranging and producing a blank A specification and then connecting a blank B specification, thus the continuous circulation arrangement is the front and back arrangement principle):
after the steelmaking data of the blank A and the blank B are transmitted to the thick plate part heating furnace, post personnel select the blank B to back the blank A on a PDI information picture, and the blank B information and the real object are normally and automatically charged; deleting the data of the blank A in the primary computer, and manually inputting the charging data of the blank A in the tertiary computer;
and during tapping, the blank B backs the blank A to automatically finish the tapping operation, then the blank B is separated from the blank A, PDI data of the blank A is manually downloaded in a secondary picture, and the secondary computer calculates a pass rule and then sends the pass rule to a primary computer for rolling, so that the rolling of the blank A and the blank B is finished in sequence.
