sliding gate plate operation principle
The sliding gate plates are installed at the bottom of ladle, they are two perforated refractory bricks work with upper nozzle and collect nozzle to control the steel flow . The upper nozzle and upper slide gate are fixed in the mechanism, the collect nozzle and slide plate can be moved left and right.
When the inner holes coincide, nozzle openning is the largest, when the nozzles are not coincident, the nozzle is closed. Sliding nozzles can improve working conditions, speed up ladle turnover, save refractory materials, reduce leakage accidents, improve slab quality and facilitate molten steel refining .
