Detailed Description
As shown in the attached figure 1, the refractory oxygen lance for opening a blast furnace comprises: the three-way pipe comprises a refractory material pipe 1 and a three-way pipe 2, wherein an oxygen pipe 3 and an air pipe 6 are respectively introduced into two pipe openings of the three-way pipe 2, the other pipe opening of the three-way pipe 2 is connected with the refractory material pipe 1, an oxygen valve 4 and an oxygen pressure gauge 5 are arranged on the oxygen pipe 3, an air valve 7 and an air pressure gauge 8 are arranged on the air pipe 6, and the refractory material pipe 1 can extend into a blast furnace.
The joints of the oxygen pipe 3, the air pipe 6 and the three-way pipe 2 are provided with sealing covers, so that gas loss is prevented.
The three-way pipe 2 is also made of a refractory material, and the connector of the three-way pipe 2 and the refractory material pipe 1 is bonded by refractory cement, so that the three-way pipe can normally work in a high-temperature environment, and a loss accessory can be automatically replaced.
The three-way pipe 2 and the fireproof material pipe 1 are made of fireproof materials, the three-way pipe 2 and the fireproof material pipe 1 are integrally formed, one pipe opening of the three-way pipe 2 is directly connected with the fireproof material pipe 1, the high-temperature working environment can be adapted, and the manufacturing process is simple.
The working process of the utility model is as follows: stretching a refractory material pipe 1 into a working position in a blast furnace, opening an air valve 7 and an oxygen valve 4, leading compressed air to pass through an air pipe 6, leading the compressed air to enter a three-way pipe 2 after passing through the air valve 7 and an air pressure gauge 8, simultaneously opening the oxygen valve 4, leading oxygen to pass through an oxygen pipe 3, leading the oxygen to pass through the oxygen valve 4 and an oxygen pressure gauge 5, leading the oxygen and the compressed air to be mixed in the three-way pipe 2 and reach the working position in the blast furnace through the refractory material pipe 1, and observing the working states of the oxygen and the compressed air through the oxygen pressure gauge 5 and the air pressure gauge 8.
While the preferred embodiments of the present invention have been described, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the general inventive concept, and it is intended to cover all such changes and modifications as fall within the true spirit and scope of the invention.
