Metering nozzle

The Zr metering nozzle manufactured by this company is specially used for the tundish gating system without plug stick in the small square-base continuous casting machine, and it is more suitable for multi-thread and small square-base continuous casting machine. All nozzles adopt special-type and high-quality refined raw materials with reasonable structure and strong erosion resistance. In the entire course of pouring, there is little change in diameter of the nozzle with stable speed. Nozzles of the mosaic type, combined type and entire difference type can also be provided as required by customers.

Aluminum Carbon Long Nozzle

Aluminum Carbon Long Nozzle

Introduction

Based on function categories, the long nozzles manufactured by our company are classified into preheating nozzle, non-preheating nozzle, argon blowing nozzle and not argon blowing nozzle, and based on material quality, nozzles mainly classified into aluminum carbon, aluminum-zirconium carbon and aluminum-magnesia carbon. This product is provided with good liquid steel washing resistance performance and liquid steel erosion performance in the course of use, which can effectively prevent oxidation of air to liquid steel and its spatter.

 

 

The requirements of refractory sliding nozzle

Sliding nozzle mainly stalled in the bottom of ladle, whose applied condition has got a big improvement comparing with plug, as its refractory part does not soak in molten steel for a long time. To sliding nozzle, slide gate is the key section, as its quality influences life span of nozzle directly.

The lower/upper nozzle only as a role of alleyway for steel running, but the upper nozzle is required to resist high temperature and eroding, which has the same life span of ladle well block. The lower nozzle is only used for one time, so which holds less demand than upper nozzle.

Both of upper/lower sliding plate are beard fastening pressure, and also required to slid and no molten steel overslow between them when pouring. So it is required to take finish machining to slip plan of upper and lower sliding plate, to make sure high parallelism and smoothness, besides, both of them are required rather high mechanical property.

Now the material of sliding plate mainly include: High alumina, Magnesia, Aluminum silicon carbide, Aluminum chromium, Aluminum carbon, and Aluminum zirconium carbon.

Above materials can be made into burned and unburned skateboarding brick.

As high quality sliding plate is expensive, one can choose  compound sliding plate, which is more appliable and economical.
