Side-blowing spray gun for melting furnace and application method thereof

Abstract

The invention relates to a side-blowing spray gun for a melting furnace and an application method thereof, and belongs to a side-blowing spray gun and an application method thereof. According to the invention, a gas connecting cylinder of the side-blowing spray gun is internally provided with a combustible gas chamber and a compressed cooling air chamber; the gas collecting cylinder is connected with a combustible gas inlet, an oxygen inlet and a compressed cooling air inlet, the oxygen inlet is located at one end of the gas collecting cylinder, and the combustible gas inlet and the compressedcooling air inlet are correspondingly connected at the positions of the combustible gas chamber and the compressed cooling air chamber; an oxygen pipe is sleeved in a combustible gas pipe, the oxygenpipe and the combustible gas pipe are sleeved in a compressed cooling air pipe, and there is a gap between the pipes; the oxygen pipe penetrates through the gas collecting cylinder, is connected to the gas collecting cylinder at the position of the oxygen inlet and is communicated with the oxygen inlet; the combustible gas pipe penetrates through the gas collecting cylinder and is connected to apartition between the combustible gas chamber and the compressed cooling air chamber; the compressed cooling air pipe is connected to the bottom end of the gas collecting cylinder; and the other end is a gas output end of the spray gun. The side-blowing spray gun has the advantages of long service life, simple structure, low cost, convenient operation, high stirring power of a molten pool, good effect and low energy consumption.
