refractory monoblock stopper

Product Description

The stopper is positioned above the tundish nozzle and attached to the stopper control mechanism by a threaded steel rod secured with threaded nuts and washers. These threaded steel rods are secured to the stopper rod by a number of means. Steel flow from the tundish to the mould is controlled by an up and down movement of the stopper rod via the control mechanism. The steel flow is then metered into the mould and can be controlled manually or automatically. Function: The  stopper rod is key to the accurate control of steel from the tundish to the mould for the purpose of maintaining a consistent level of steel in the casting mould. High performance is essential to ensure that casting is not disrupted due to loss of control of steel flow or stopper failure. Correct design, high quality and correct choice of materials is essential for high sequence casting.
