Part of workshop
Jinan Linquan provide a very wide range of Tundish Nozzles used for controlling the flow of steel from the Tundish to the Continuous Casting equipment including:
Zirconia/ Zircon Nozzles – Manufactured in 65% to 95% Zirconia.
Isostatically Pressed Nozzles – made in Alumina Carbon quality for medium and small steel plants.
1) Serivice life depends on steel-making condition, refractory slide gate and different operation mode.
2) 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 is 35-50 days.
