TH90-ZK20Q Tundish Calibrated Nozzle Changer

4.1 In the case of casting smoothly in tundish, the gate can change nozzle plate quickly many times online, there are no limit of nozzle plate life in tundish online continuous casting time, it can improve the service life of the tundish significantly.
4.2.It can replace the nozzle plate with different diameters online to adjust the flow velocity in the tundish, and implement appropriate matching with the casting speed and make the steelmaking and continuous casting keep the same pace.
4.3 when one strand of the mold occurs fault, you can use the blind plate to river closure and maintain the mould online. Therefore, after failure recovery, the replacement of a new nozzle plate need be finished quickly so that the casting can start again, to meet the continuous casting process requirements.
4.4.When the tundish stop teeming or other failures, you can replace the blind plate to river closure immediately, and make corresponding treatment for the tundish.
4.5 Gate design considers the effect of temperature on the elastic element, for this reason, it uses the unique design for heat insulation and reasonable spring arrangement, so that make the spring far away from high heat area, minimizing thermal influence. It enables the use of gate more safely, reliably, and has a longer service life.
4.6 The main body of the gate uses heat resisting refractory, to avoid the shortcomings of welding steel structure which includes short working time, easy to deformation and the high accident rate, so it has a long service life.
4.7 It has scientific and reasonable structure design, operation and maintenance is simple and convenient.
