LQ-Series Ladle Slide gate plates
1)High Temperature Burnt Slide Plate
Adopts tabular alumina, carbonaceous material and zirconia-containing material as main raw materials, adds in high performance antioxidants, uses phenolic resin as binder, formed under high-pressure and burned under high temperature. Mainly used in large and medium-sized ladles.

1. Serivice life depends on steel-making condition, refractory slide gate and different operation mode. The above performance is based on the conditions of ladles with capacity of over 100 tonnes.
2. For composited slide plate, we can mark different material in different part and detailed indexes according to the drawings.
3. Delivery time depends on the drawing. If new moulds are needed, an additive period may be necessary. Total time ususlly will be 25-50 days.
