Automatic gun for driving OUTLET metallurgical furnace

摘要

1. Gun for sealing the taphole of a metallurgical furnace, comprising silovoytsilindr for receiving the sealing mass and sealing the piston to displace the sealing mass from the mouthpiece cylinder pressed against the outlet of the furnace, characterized in that the actuator (11) has a tube (21) of the cylinder with the inserted in her system (18) of wear liner which is formed with at least one insert liner (25, 26) of the welded sheet blank (31) .2. Gun according to claim 1, characterized in that the insert liner (25, 26) is formed from a sheet metal blank (31) preformed into a tube with a longitudinal welded shvom.3. Gun according to claim 1 or 2, characterized in that the sheet blank (31) is obtained by heat treatment of the hardened low carbon stali.4. Gun according to claim 3, characterized in that the carbon content of the steel sheet blank (31) is less than 0.5 wt.% And the chromium content is less than 1.5 wt.%. 5. Gun according to claim 4, characterized in that the carbon content of the steel sheet blank (31) is less than 0.25 wt.% And the chromium content is less than 0.75 wt.%. 6. Gun according to claim 1, characterized in that the wall thickness of the insert liner (25, 26) is at least 10% of the wall thickness of the pipe (21) tsilindra.7. Gun according to claim 6, characterized in that the wall thickness of the insert liner (25, 26) is from 20% to 40% of the wall thickness of the pipe (21) tsilindra.8. Gun according to claim 1, characterized in that the system (18) of wear inserts consist of two plug inserts (25, 26) .9. Gun according to claim 8, characterized in that the plug inserts (25, 26) of the system (18) wear liners are inserted in the tube (21) of the cylinder so as to form the mutually facing end behavior
