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 index according to the drawings.

3. Delivery time depends on the drawings. If new moulds are needed, an additive period may be necessary. It ususlly takes 35-50 days.
