Solutions to improve service life of ladle slide gate plate

slide gate plate

Slide gate plate is the most important part among the slide gate nozzle system, which directly control the flow of the molten steel. Due to long time contact with high temperature molten steel and frequently strong heat impact, it easily got spoiled. Following are some solutions that could promote slide gate plate service life.

1.Types of slide gate plate
It is better to use the alumina- carbon based slide gate plate, which has a good erosion and strong thermal shock resistance. Bonded with carbon material, this type of slide gate characterized with high thermal conductivity and low thermal expansion coefficient.

2.Installation of slide gate plate
Make sure the fire mortar has a suitable proportion, mixed well and suitable proportion and no impurities. Never use the dried and lumpy mortar. It is also not acceptable to mix the new mortar with the used one. Make sure the upper nozzle is clean, no any residue in refractory company slide gate frame and sliding mechanism. Before installation, make sure the slide gate are not deformed or cracked. Keep the slide gate steady and smooth during the installation, and check whether there is any bump and swing after installation.

3.Using of slide gate plate
It is better to adapt auto cast program when casting steel, do not frequently and drastically open or close the slide gate. Once in need of burn oxygen, the slide gate plate must be fully opened and discharge the slide gate sand as much as possible.

Changxing Refractory material not only provides qualified slide gate plate, but also can dispatch technician for site service. Shall be any interest, please contact us.

The notes for using slide gate plate

slide gate plate

1.Hot mechanical damage, hot chemical erosion and misoperation are the main three reasons for the damage of slide gate plate;

2.Use alumina zirconium carbon slide gate plate, ensure slide gate plate has good erosion resistance and thermal shock resistance; use slide gate and mechanism with reasonable design and even stress distribution, the service life of slide gate plate can be effectively improved;

3.Follow the standard operation procedure during the tapping of molten steel; right and good maintenance of refractory material slide gate plate can also improve the service life of slide gate plate.
