Abstract
The utility model relates to a baking device used in an RH vacuum chamber bottom circulation tube. The baking device comprises a burning nozzle, a burning nozzle placing device, a gas transmission pipe connected with the burning nozzle, an electromagnetic valve connected to the gas transmission pipe, a control cabinet connected with the electromagnetic valve through a guide line, and a cover plate. The cover plate with a hole is connected to the burning nozzle placing device. The baking device has the advantages of enhancing baking uniformity of the vacuum chamber bottom circulation tube, preventing the problems that vacuum chamber bottom refractory bricks break, peel off or diffuse steel, and ensuring smooth production of various steel.
Description
Technical field
The utility model relates to roaster, specifically belongs to the roaster that is used for RH vacuum chamber bottom cycle pipe.
Background technology
Vacuum chamber bottom cycle pipe is to guarantee that the critical component of molten steel circulation also is simultaneously the weakest position, vacuum chamber bottom.Circulation pipe connects with the insertion pipe, and it is the most serious washed away by molten steel, and the operating mode stress condition is poor, occurs rupturing, peeling off, ooze the steel problem easily.Circulation pipe is the dead angle that is in baking flame in original bottom roasting plant, and cured effect is not good, has a strong impact on vacuum chamber anti-material life-span of bottom and vacuum chamber turnover.For avoiding occurring above-mentioned consequence, need guarantee vacuum chamber bottom cycle pipe cured effect with a kind of reliable method.
The utility model content
The purpose of the utility model is to overcome above-mentioned deficiency, provides a kind of vacuum chamber bottom cycle pipe baking temperature that makes even, and cured effect is good, the roaster of the RH vacuum chamber bottom cycle pipe of the life cycle of raising vacuum chamber bottom cycle pipe.
Realize the technical measures of above-mentioned purpose:
A kind of roaster of RH vacuum chamber bottom cycle pipe, it is: it comprises the magnetic valve that connects on burner, burner placer, the gas conveying tube that is connected with burner, the gas conveying tube, is connected switch board, is connected in the cover plate with holes on the burner placer through lead with magnetic valve.
It is characterized in that: the burner placer is made up of the flame retardant coating in shell, the shell, aluminum silicate ceramic layer on the flame retardant coating.
It is characterized in that: on gas conveying tube, be connected with hand-operated valve.
It is characterized in that: the burner placer is placed at least one burner.
It is characterized in that: the burner placer is arranged on the support; Burner placer side is provided with burner and picks and places the hole.
It is characterized in that: the hole on the cover plate evenly distributes.
It is characterized in that: the alarm that is connected with magnetic valve is housed on the switch board.
The characteristics of the utility model are: can strengthen the uniformity of vacuum chamber bottom cycle pipe baking, thereby prevent that the vacuum chamber bottom refractory brick from rupturing, peeling off, ooze the steel problem, guaranteed the production direct motion of variety steel.

Fig. 2 is a plan structure sketch map local among Fig. 1
Among the figure: the 1-burner, 2-burner placer, the 3-gas conveying tube, the 4-magnetic valve, the 5-lead, the 6-switch board, the 7-hole, the 8-cover plate, the 9-shell, the 10-flame retardant coating, 11-aluminum silicate ceramic layer, the 12-burner picks and places, 13-hand-operated valve, 14-support.
The specific embodiment
Do below in conjunction with accompanying drawing and to further describe:
A kind of roaster of RH vacuum chamber bottom cycle pipe; It comprises burner 1; Burner placer 2 is with the gas conveying tube 3 that burner 1 welds or is threaded, the magnetic valve 4 that connects on the gas conveying tube 3; Be connected switch board 6 with electromagnetism 4 through lead 5, be connected in the cover plate that is evenly distributed with hole 78 on the burner placer 2.
Described burner placer 2 is by shell 9, the flame retardant coating 10 in the shell 9, and the aluminum silicate ceramic layer 11 on the flame retardant coating 10 is formed; Be processed with burner in burner placer 2 sides of forming by above-mentioned parts and pick and place hole 12, to take out or to place burner 1.
And on gas conveying tube 3, also being connected with hand-operated valve 13, with subsequent use.
In burner placer 2, be placed with one or two burners 1, its placement quantity decides according to the size of burner 1.
According to the size of RH vacuum chamber bottom cycle pipe area occupied, can on support 14, place a plurality of burner placers 2, be principle with the baking of satisfying RH vacuum chamber bottom cycle pipe.
Operating principle
At first, coal gas is fed in the gas conveying tube 3; According to setting to such an extent that toast curve, open magnetic valve 4 buttons in the switch board 6, and regulate gas flows through magnetic valve 4; Start bottom cycle pipe baking igniting; Toast after 32/45 hour and cease fire, baked RH vacuum chamber bottom cycle pipe is transported.
