Problems solved by technology
Because a single pressure acts on multiple contact surfaces, the layers are weakened and changed, the magnitude and direction of the pressure are difficult to balance, and the local area is too tight or too loose
Changes in the quality and viscosity of the refractory mud between the snap-in buttons will also affect the stability of the pressure
Uneven stress, complex operation, low system reliability, steel clamping and steel leakage occur from time to time, resulting in a decrease in the number of consecutive slips

The invention discloses a sliding nozzle device which comprises a base brick, an installation plate fixed to a steel ladle, and a base fixed to the installation plate. A vertical upper nozzle brick is embedded in the base brick, the installation plate and the base. A circular upper slide plate brick fixed through a fastening sleeve is arranged in the base. The left side and the right side of the base are each provided with a plurality of spring holes. A spring is arranged in each spring hole and provided with a prepressing plate. A slide plate is arranged below the base. A lower slide plate brick and a lower nozzle brick are arranged in the slide plate. A driving plate is fixed to the front end face of the base. A driving mechanism for driving the slide plate to slide is arranged on the driving plate. A slide box pin is arranged at the rear portion of the base and sleeved with a slide box. A slide plate groove is formed in the slide box. The slide plate is inserted in the slide plate groove. The left side and the right side of the slide box are each provided with a slide box pressing plate. The sliding nozzle device has the advantages that the structure is simple, the sliding contact face is balanced, stable and adjustable in pressure, sealing performance is good, and molten steel can be prevented from overflowing in the sliding process of the slide plate brick.
Description
technical field [0001] The invention relates to a ladle casting sliding nozzle device, in particular to a novel sliding nozzle device which saves consumption of refractory materials. Background technique [0002] Since the 1970s, the sliding nozzle has become one of the important technological innovations in the rapid development of the iron and steel industry. At present, most of the ladles and tundishes at home and abroad are equipped with sliding nozzle systems. Due to the limitations of the production process, raw materials, production equipment, and design concepts of refractory materials in the early days of the invention of the sliding nozzle device, the size of the refractory part of the sliding nozzle device at that time was designed to be too large, firstly to ensure safety, and secondly Large-size refractories can enable refractory manufacturers to obtain higher economic benefits. Although the sliding nozzle devices used in various steel mills have undergone man...
