A sliding nozzle generally consists of a drive mechanism, a mechanical component, and a refractory material section (i.e., upper and lower slides and the lower nozzle). The operating principle of a sliding nozzle is to use a sliding mechanism to slide the upper and lower slides, thereby opening and closing...

Working Principle of the RHG-B3 Ladle Sliding Gate: The mechanism primarily consists of a base assembly, a slider assembly, a bracket assembly, a drive assembly, and a refractory assembly. The base assembly is fixed to a mounting plate. The slider, equipped with wheels, moves on the bracket track. Pressure is...

Refractory materials are primarily used in high-temperature industries such as steel, building materials, non-ferrous metals, and military applications. A sliding gate mechanism is a device used to control the flow of molten steel during steelmaking. Currently, there are numerous sliding gate mechanism suppliers, with Hebei Ruihua Metallurgy being a prominent...

The ladle sliding nozzle is a critical system for controlling the flow of molten steel within the ladle. If a steel breakage accident occurs during operation, it will lead to serious production accidents such as disconnection of the continuous casting machine and equipment burnout, restricting the smooth operation of production...

Product quality is the foundation of an enterprise's survival and one of the important indicators to measure the quality of an enterprise's products. If an enterprise wants to gain a firm foothold in the fierce market competition, it must practice internal skills and strengthen quality management of the production process....

When installing the nozzle on a new ladle (or new base brick), first clean any mud and debris from the base brick hole. Then, test-fit the selected (pre-baked) nozzle. Apply an appropriate amount of mud to the outer periphery of the nozzle, depending on the gap between the base brick...

A sliding nozzle controls the flow of steel by adjusting the relative offset between two open-hole refractory bricks connected and assembled together via a sliding mechanism installed at the bottom of the ladle. The advantages of a sliding nozzle include improved working conditions, faster ladle turnover, reduced refractory material consumption,...

With the development of rapid, efficient continuous casting and secondary refining technologies and processes, the sliding nozzle (SN) system has become increasingly important in modern steelmaking, becoming an indispensable component. It is a control device for molten steel during the continuous casting process, precisely regulating the flow of water from...

In May 2022, Hebei Ruihua Metallurgical Technology Co., Ltd. (hereinafter referred to as Ruihua) successfully passed the ISO9001 quality management system, ISO14001 environmental management system, and ISO45001 occupational health and safety management system certification audits, marking that Ruihua has taken a new step in refined, institutionalized and standardized management. The...
