Abstract
A preheating material tank relates to a device used for steelmaking furnace lining spraying. The preheating material tank comprises an exhaust collector, a material tank, a motor, a supporting roller, a driving gear, a hydraulic cylinder, a shaft, a gear ring, a positioning sleeve ring and a base. The material tank bottom is hinged with a frame on the base through the horizontally disposed shaft, and the supporting roller for supporting the material tank is arranged on the base. A discharge port is provided in the material tank bottom. The positioning sleeve ring is sleeved on the material tank. The hydraulic cylinder bottom is hinged with the base, and a piston rod of the hydraulic cylinder is hinged with the positioning sleeve ring. Stretching and shrinking of the hydraulic cylinder piston rod make the material tank rotate around the shaft. The base is provided with a horizontal track and the exhaust collector is arranged on the horizontal track. When the material tank is horizontally arranged, the exhaust collector is connected with an exhaust port on top of the material tank. The gear ring is fixed on the material tank. The base is provided with the motor. The driving gear is provided on the motor rotary shaft. The driving gear is engaged with the gear ring. The material tank of the invention solves the problem of an unsatisfactory gunning effect as refractory powder cannot be burnt into a molten state in the prior gunning method.
Description
Technical field
The present invention relates to the equipment that iron company's converter liner spraying is used.
Background technology
At present, " the flame gunning material formula and the method " of prior art only limits on temperature is 1200 ℃ glass kiln, use.Contain metallic aluminium powder in this gunning mix, the fusing point of aluminium powder only has 660 ℃, and aluminium powder is melted into binding agent in advance in the thermal-flame band, thereby adheres to the refractory powder that in the normal temperature batch can, gushes out on the glass kiln liner.Because refractory powder is not by scorification, thereby the spray repair effect is undesirable, just generally do not promote yet.At present, iron company repairs with semidry method, all is the normal temperature batch can, can not be the refractory powder scorification.
Summary of the invention
The purpose of this invention is to provide a kind of preheating batch can.The invention solves in the prior art spraying method because refractory powder not by scorification, causes the unfavorable problem of spray repair effect.
Preheating batch can of the present invention is made up of smoke evacuation gatherer 1, batch can 2, motor 3, supporting rolling ring 4, driving gear 5, hydraulic cylinder 6, axle 7, gear ring 9, location lasso 10 and base 11; Batch can 2 bottoms are hinged with the frame on the base 11 through horizontally disposed axle 7, and the supporting rolling ring 4 that is used to support batch can 2 is installed on base 11; Discharging opening 8 is arranged at batch can 2 bottoms; On batch can 2, be set with location lasso 10, hydraulic cylinder 6 cylinder base are articulated on the base 11, and hydraulic cylinder 6 piston rods are hinged with location lasso 10, and the flexible batch can 2 that makes of hydraulic cylinder 6 piston rods rotates around axle 7; Be equipped with horizontal rail 11-1 on the base 11, smoke evacuation gatherer 1 is installed on above the horizontal rail 11-1 and both formation are slidingly matched; Smoke evacuation gatherer 1 connected batch can 2 top exhaust openings when batch can 2 was horizontally disposed with; On batch can 2, be fixed with gear ring 9, motor 3 is installed on the base 11, in motor 3 rotating shafts driving gear 5 is installed, driving gear 5 and gear ring 9 engagements.
Batch can 2 center lines rise to when becoming the α angle position with level along axle 7,40 °＜α＜85 °.
Batch can rotation speed n in the heating process (rev/min) 0＜n＜20.
High-temperature and wear-proof layer 2-1 arranged on the internal chamber wall of batch can 2, and cavity temperature is 800 ℃ in the batch can--and 1500 ℃.
Preheating batch can of the present invention; Can before spray repair, be heated to 800 ℃ to refractory material--1500 ℃; The refractory powder of different formulations can heat the interior different temperature points of temperature section so far; Make refractory material before spraying, become the fritting state, 2500 ℃ flame zone burns till molten condition with refractory material between process nozzle and converter liner.After treating that the spray repair layer solidifies, moisture because of it, do not contain binding agent, the density of spray repair layer has not improved greatly, and the spray repair layer has improved the erosion-resisting characteristics and the scour resistance of molten steel greatly.Because these superior functions; After converter liner (refractory thickness is more than the 800mm) integral body is carried out flame-spraying; Integral lining thickness will reduce nearly 1/3rd; Thereupon the outer steel frame construction weight of converter also reduce nearly 1/3rd, nearly 1/3rd thereby the power of motor that converter is rotated reduces, finally reach the purpose that reduces ton steel cost.On the other hand, the temperature in the converter is high more, helps the enforcement of flame gunning more.That is to say, rotate that as long as can reveal the part that is corroded by molten steel, flame gunning just can be implemented to repair, thereby has improved steel-making efficient greatly under the condition of not blowing out steel-making through converter.
