Description

The invention relates to metallurgy and is intended to be treated with liquid gases and powders in a casting ladle.

The purpose of the invention is to increase the reliability of the device ,.

The drawing shows the device, general view, section.

The device consists of a ladle cup, 1, inserted into a steel casting ladle 2, located under the ladle cup 1 fixed 3 and the movable 4 refractory plates with pouring channels 5, in which the injection tube 6 is located, passing through the collector cup 7 and the ladle cup 1. B. casting channels 5 of the upper and lower refractory plates are fitted with steel rings 8, to the cutting edge of ring 8 with the plane of sliding of plates 3 and 4. Between the tube 6 and the walls of the opening of the bucket cup 1 and the pouring channel 5 of the upper, 5 fixed plate 3 refractory material is sprinkled. 9..

The device works as follows.

Before steel is cast, it is machined in a ladle 2 by blowing gases and powder through an injected pipe -6. In the case of a slag bucket 2, the movable plate 4 is set in motion, cuts the tube 6. The gas supply and the powder is stopped. The forces required to cut the tube 6, perceived by steel rings 8, are uniformly distributed over the entire surface of the casting channels 5 and the previous pipe, for example, the top, 20 and wound the refractory plates 3 and 4 from the injection pipe 6. The thickness of the steel rings 8 is 3 to 5 mm. To fix the rings 8, plates 3 and 4 are in the initial position shifted relative to each other and the upper ring B is mounted on the lower plate 4, ensuring that the plane coincides

Before steel is cast, it is machined in a ladle 2 by blowing gases and powder through an injected pipe -6. In the case of a slag bucket 2, the movable plate 4 is set in motion, cuts the tube 6. The gas supply and 15 times each stop. The forces required to cut the tube 6, perceived by the steel rings 8, are uniformly distributed over the entire surface of the casting channels 5 and 25
