Recently, we did a free upgrade of Tundish Metering Nozzle for our customers.Pervious the Tundish Metering Nozzle made according to the customer's drawings and there was an edge(as picture 1) at the joint of the zirconia insert and the outer, which caused the liquid steel to not flow smoothly .In order to help the customer solve this problem, our technical staff constantly tried to improve the production technology, and finally successfully removed the edge at the joint, now the joint between the zirconia insert and the outer of the product are smooth(as picture 2), so that the liquid steel flow was very smoothly, and the quality of the steel products produced by the customer was improved.

LONGKETER has been committed to product innovation,technology upgrading to provide customers with higher technical support,better quality products and better service.
