  • Boom 24.0f apparatus 10 and gunning pipe 12 are inclined downwardly into refractory lined vessel 16 to direct gunning pipe 12 and the stream of pressurized refractory fluid 26 into and about worn area 20 in lining 22.
  • tubular boom-24 is received within barrel framework 28, which is rocked upwardly about pivot bearings 30 at the tops of bracket posts 32 by the reaction of hydraulic piston and cylinder assembly '34 between turntable 36. and connecting link 38 on the bottom .of barrel framework Boom 24 is fully extended in front of barrel. 28 by the fully engaged position of upperhydraulicpiston and cylinder assembly 40 transmitted through collar assembly 42 joining it to the rear of boom 24.
  • Boom 24 extends through window 43 in insulated shield 45 which comprises sheets 47 of mineral wool composition in a frame 49 of steel angles.
  • Swivel coupling 48 isolates the rotypical construction equipment such as a power shovel or mobile crane.
  • the various movements of apparatus 10 are electrically controlled by an operator 54 operating a pushbutton control box 56 away from the heat of vessel 16.
  • FIG. 2 shows the extent of the various movements of apparatus 10 including upward and downward rocking of boom 24 and barrel 28 about bracket pivots 30 to an upwardly inclined angle a of approximately 15 and a downwardly inclined angle b of approximately 40.
  • Boom 24 and gunning pipe 12 are for example extendable and retractable relative to barrel framework 28 and carriage 52 by actuation of piston and cylinder assembly 40 a distance I which is for example approximately seven feet.
  • Gunning pipe 12 extends for example in front of boom 24 from about zero to twenty feet and preferably extends in front of boom 24 about ten to twelve feet.
  • Carriage 52 is for example driven by a hydraulic motor 58 which drives caterpillar tread assembly 60 and hydraulic motor 62 which rotates turntable bull gear 64 through pinion 66.
  • Gunning pipe rotating motor 44 is also for example a hydraulic motor supplied, through a conduit 68 leading to a suitable source of hydraulic pressure (not shown).
  • Radial plates 72 spacethe outer shell 74 of boom 24 from inner, shell 76.
  • FIGS. 2 3 and 5 also show rear bearing 78 within which gunningpipe 12 is rotatably connected to rear head 80 of boom 24.
  • Compressed air is admitted into'annular space 82 between boom inner shell 76 and g nningpipe 12 through one of holes 84 in rear boom head 80 to which compressed air hoses 86 are connected.
  • the compressed air flows through four holes 88 (shown in FIG. 6) in the front head 90 of boom 24.
  • FIG. 6 also shows hole 92 in the front of boom 24 for rotatably receiving gunning pipe 12.
  • FIG. 4 shows how boom 24 is received within an array of resiliently biased centering rollers 94 mounted within barrel framework 28 and about the periphery of boom 24.
  • Each of the three roller assemblies 94 is resiliently biased by springs 96 in resilient engagement with boom 24 for guiding its forward and backward move ment within double tapered guiding and receiving rollers 98 in response to actuation by piston and cylinder assembly 40.
  • FIG. 4 also shows the welding of stub shafts 100 to the bottom of I beams 102 on the sides of rectangular barrel framework 28 and the insertion of shafts 100 within bearings 30 at the top of bracket posts 32.
  • FIG. 7 shows a modified nozzle 104A attached to the front of gunning pipe 12A for directing a stream 26A of refractory material at a worn area 20A in the wall of refractory vessel 16A which could not be reached by straight gunning pipe 12.
  • Outlet 106A of nozzle 104A is directed at an angle of approximately 20 to the longitudinal axis of gunning pipe 12A which discharges a cone of gunned material 26A as a result of the rotation of gunning pipe 12A.
  • Nozzle 104A is similar in construction to that shown in US. Pat. No. 3,392,921 other than in the aforementioned angular inclination.
  • Apparatus 10 is capable of extremely rapid approach and efficient and rapid repair of worn portions of refractory lined vessels. It also enables an operator 54 to position himself for efficient control of the operation and protection from the heat of the vessel. Apparatus 10 is actuated by a hydraulic motor system, partially shown herein. The hydraulic system is energized by a diesel engine, hydraulic pump and accumulator of any effective type, which are not shown herein. The operator 54 can actuate all of the movement through switchbox 56, which for example includes pushbuttons for actuating each of the required movements including hydraulic piston and cylinder assemblies 34 and 40 and crawler motor 58, including the rotation of turntable 36.
  • Motor 44 for rotation of gunning pipe 12 is for example reversible and effectively operates in either direction at a speed from about I to rpm. This rotation prevents the gunning pipe from being deformed by the heat in the vessel, particularly, the very high radiant heat.
  • the various movements of apparatus permits a refractory spray to be effectively applied either to the bottom or sides of vessel 16 with the aid of an angularly offset nozzle 104A such as shown in FIG. 7.
  • Inner shell 76 of boom 24 is for example made of schedule eighty pipe to provide the strength required to dependably hold gunning pipe 12 in its required position.
  • Inner stiffening plates 72 also stabilize the boom. Insulating sheath 70 and the flow of cooling air depicted by arrows 108 in annular space 82 (between inner boom shell 76 and gunning pipe 12 and out I through exit holes 88 in front head 90 of boom head 24) help prevent boom 24 and gunning pipe 12 from becoming overheated in service.
  • Water control valve 57 is connected in conduit 55 to maintain a substantially constant quantity of water flowing into mixing tee 51, whereby substantially constant proportions of refractory material and water are supplied through conduit 50 and swivel coupling 48 to gunning pipe 12.
  • the dry refractory is provided to mixing tee 51 through conduit 53 connected to a sourceof dry refractory material (not shown) usually referredto as a refractory gun.
