Description

Brick flow nozzle of medicinal glass nozzle

Technical Field

The disclosure relates to the technical field of material flowing nozzle bricks, in particular to a material flowing nozzle of a medicinal glass material flowing nozzle brick.

Background

At present, the nozzle brick suitable for the Dana method tube drawing system is generally short in service life, and as the service life increases, the material belt is wider and wider, and the main reasons are as follows:

firstly, because glass has very high viscosity when flowing through the material nozzle brick, the glass liquid washes the material nozzle brick flow opening at night and the day after night, and the current material nozzle brick often has a large amount of bubbles at the corner due to technical defects when pouring, so that the corrosion speed of the refractory material at the lower end of the flow opening to the glass liquid is extremely high, the bubbles in the refractory material and the partially peeled refractory material can enter the glass liquid to form refractory material stones and secondary bubbles.

Secondly, due to the particularity of the material flowing port, the shape of the material flowing port becomes irregular after the material flowing port is washed by glass liquid for a long time, the material flowing band is wider and wider under the action of the tension of the glass liquid, and even the situation of uneven liquid flow of the material flowing band occurs.

Finally, the service life of the material nozzle brick is determined by the change of the material belt and the sensitivity of the flashboard gate material, and the corrosion speed of the liquid nozzle directly determines the change speed of the material belt, namely the corrosion speeds of the two sides of the liquid nozzle directly determine the service life of the material nozzle brick.

The above reasons lead to frequent adjustments of the forming process, directly affecting the yield of the tube drawing system.
