Instructions for making a furnace gun
1. The structure form is combined, cooling water jacket, oxygen spray gun, carbon spray tube combination. The main nozzle adopts the design of the laval nozzle to ensure the supersonic oxygen supply characteristics.
2. The pure copper cast water cooling jacket and porous oxygen gun nozzle ensure the cooling effect, and the pipeline adopts the method of taking over from the total oxygen tube, and the oxygen tube adopts 1Cr18Ni9Ti seamless tube.
