LQ Purge Plug
1. porous plug brick for steel ladle
high aluminum porous plug and porous plug brick for steel ladle are shaped by pressing, prefabrication and vibration. With subtle formula design, unique technical process, they have good performance on Erosion-resistance, high temperature performance and also longer service life, which identified up to the leading domestic level and received recognition and praise

1. Serivice life depends on steel-making condition, refractory slide gate and different operation mode. The above service life we supply is based on the condition of more than 100 Tons ladle.
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. In general it takes 30-50 days.
