Square and round billet continuous casting mold installation

1. When the mold is offline, equipment maintenance, copper tube inspection, pressure test, arc, nozzle inspection, etc. have been completed and meet the online requirements. Under this premise, the mold is hoisted to the pouring platform for mold installation.

2. If the crystallizer has built-in electromagnetic stirring, it needs to be tested offline. If the external electromagnetic stirring of the crystallizer is used, when installing the crystallizer, the electromagnetic stirring must be placed on the online stirrer mounting bracket. The continuous casting machine suppliers have different design concepts, and the installation position of the agitator is different.

3. After the online mold electromagnetic stirring device is installed, the mold is hoisted on the vibration device. The connection between the vibration device and the mold cooling water is usually automatic. The mold installation is determined according to the positioning pin on the vibration device For the position, the arc alignment device is adopted to make the arc of the mold copper tube coincide with the basic arc radius of the continuous casting machine. If it exceeds the allowable range of error, the mold needs to be adjusted accordingly, and the fixing device is used to lock it after the adjustment.

4. Connect the crystallizer cooling water online to check whether the crystallizer and the vibration device water-receiving plate are sealed, whether there is water leakage, start the vibration device, and observe whether the crystallizer is unlocked or swayed.

5. After checking, close the mold cover to complete the installation work. Start the secondary water system and check whether the cooling pipeline in the foot roller area is unobstructed.

6. There is no problem in the whole inspection process, and work such as simulated pouring can be performed. After the simulation is completed, the ingot rod is sent to the final position of the lower mouth of the mold, and the cooling water in the copper pipe is blow-dried by compression, and the cold material is filled to prepare for pouring. .

    In continuous casting, low corrosion resistance often occurs, which directly leads to uneven composition and will eventually affect the smelting quality. In or
