Abstract
This utility model relates to a combined nozzle for small square billets used in continuous casting. It includes a nozzle body with a water inlet and an air inlet on its lower end face, and several nozzles of different specifications on its upper end face. Each nozzle has a mixing chamber inside. The water inlet is connected to the mixing chamber via a water spray channel, and the air inlet is connected to the mixing chamber via an air jet channel. Both the water inlet and air inlet are equipped with filters. A nozzle head is installed on one nozzle, and plugs are installed on the other nozzles. This utility model has a simple structure and is easy to manufacture. When used for secondary cooling of square billets with different end faces, the corresponding plugs can be replaced with nozzles. Nozzle replacement and maintenance are convenient and quick, making it highly practical.
