Field other equipment is also running well, and wastes energy consumption.
The content of the invention
It is an object of the invention to provide it is a kind of change sintering pallet method, can will change sintering pallet time
It shorten to 15 minutes, effectively reduces sintering production process energy consumption.
To achieve the above object, the present invention is realized using following technical scheme：
1st, a kind of method for changing sintering pallet, specific method are as follows：
1) spare unit chassis is selected, it is stand-by to sling standby chassis with crane；
2) defect chassis is found, tracks running position, before defect chassis runs to igniter, notifies master control room, by
Step reduce mixture ore trough reserves to the 1/6-1/3 of ore deposit groove controlling level locate, when defect chassis reach mud roller distributing device lower section when,
The defect chassis bed of material is reduced at the 1/4-1/2 of chassis controlling level；
3) spare unit chassis is hoisted to crane the position of sintering machine table top tail the 4th bellows reciprocal, in sintering board
Hovering is stand-by above face；
4) defect chassis stops sintering machine operating, together after igniter when running to tail the 5th bellows reciprocal
When, master control room closes main exhausting door, and sintering machine has a power failure, and igniter gas flow is controlled in 90m3/h-120m3/h；
5) rear of sintering machine rocker is opened in place, loosens sintering pallet gap；
6) standby chassis is put off on sintering machine table top, lifting steel cable decoupling device；
7) another group of lifting steel cable is suspended on defect chassis, lifting steel cable other end is hung on crane；
Above step 5,6,7 is carried out simultaneously；
8) defect chassis is hung out with crane, falls on sintering machine table top, pluck crane hook；Crane is hooked on spare unit chassis to hang
On steel loading rope, spare unit chassis is put off on sintering machine track, takes crane hook；
9) the side trolley wheel of defect chassis is sling with crane, on sintering deposit to the spare unit chassis on defect of tumbling chassis,
Lifting steel cable is hung on defect chassis four wheels, slings defect chassis；
10) mixture ore trough feeding, rear of sintering machine rocker return open main exhausting door, and gas for ignition flow recovers；
Step 9,10 are carried out simultaneously；
11) sintering machine operates, and changes chassis and terminates.
Compared with prior art, the beneficial effects of the invention are as follows：
A kind of method for changing sintering pallet, the time that change sintering pallet can be shorten to 15 minutes, effectively
Reduce sintering production process energy consumption.
Embodiment
Embodiments of the present invention are further illustrated with reference to specific embodiment：
1st, a kind of method for changing sintering pallet, it is characterised in that specific method is as follows：
1) spare unit chassis is selected, it is stand-by to sling standby chassis with 50t cranes.
2) defect chassis is found, running position is tracked, treats that defect chassis is run to before igniter, notifies master control room, by
Step reduce mixture ore trough reserves to the 1/6-1/3 of ore deposit groove controlling level locate, when defect chassis reach mud roller distributing device lower section when,
The defect chassis bed of material is reduced at the 1/4-1/2 of chassis controlling level.
The purpose for reducing mixture ore trough reserves is to prevent from changing swollen groove not blanking after chassis.
Reduce the defect chassis bed of material purpose be：First is the lifting weight for mitigating defect chassis, is conveniently replaceable chassis.The
Two can prevent the sintering deposit in chassis from can pollute pallet slideway.3rd when being that defect chassis is sling, and prevents inside chassis
Sintering deposit part is fallen into flue, blocks flue double beat valve.In addition, adjacent two pieces of chassis of defect chassis are also required to suitably reduce
At the bed of material to half.
3) spare unit chassis is hoisted to 50t cranes the position of sintering machine table top tail the 4th bellows reciprocal, in sintering machine
Hovering is stand-by above table top.
4) defect chassis stops sintering machine operating, together after igniter when running to tail the 5th bellows reciprocal
When, master control room closes main exhausting door, and sintering machine has a power failure, and igniter gas flow is controlled in 90m3/h-120m3/h。
5) rear of sintering machine rocker is opened in place, loosens sintering pallet gap.
6) standby chassis is put off on sintering machine table top, lifting steel cable decoupling device.
7) another group of lifting steel cable is suspended on defect chassis, lifting steel cable other end is hung on 50t cranes.
Above step 5,6,7 is carried out simultaneously, amounts to 5 minutes used times.
8) defect chassis is hung out with 50t cranes, falls on sintering machine table top, pluck crane hook；Crane is hooked on spare unit platform
On car lifting steel cable, spare unit chassis is put off on sintering machine track, takes crane hook；The step amounts to 4 minutes used times.
9) the side trolley wheel of defect chassis is sling with 50t cranes, the sintering deposit on defect of tumbling chassis to spare unit chassis
On, lifting steel cable is hung on defect chassis four wheels, slings defect chassis.
10) mixture ore trough feeding, rear of sintering machine rocker return open main exhausting door, and gas for ignition flow recovers.
Step 9,10 are carried out simultaneously, amount to 5 minutes used times.
11) sintering machine operates, and changes chassis and terminates.
Embodiment 1：
By taking certain ㎡ 1# sintering machine of West sintering work area of steel mill 328 as an example.
1) post finds to rock in tail 7# bellows position, 43# chassis the near front wheels, there is the possibility to drop, report master
Control room.
2) production determines to change 43# defect chassis.Spare unit chassis is selected, it is stand-by to sling standby chassis with 50t cranes.
3) 43# chassis running position is tracked, treats that 43# chassis is run to before igniter, progressively controls mixture ore trough material
Position to 30 tons (1/6th positions of ore deposit groove).
4) when 43# chassis is run to mud roller cloth, master control room reduces cloth doses, and it is 180mm to reduce the 43# chassis bed of material
Thickness (bed of material is down to a quarter opening position of chassis controlling level).Adjacent two pieces of chassis of defect chassis also reduce the bed of material extremely
360mm (bed of material is down to the half opening position of chassis controlling level).It is thick for 720mm that other chassis recover normal blanking thickness
Degree.
5) it is stand-by spare unit chassis to be transported to 50t cranes hovering above the sintering pallet of 9# bellows position.
6) when 43# chassis is run to 8# bellows positions, master control room stops sintering machine, closes main exhausting door, gas for ignition flow
100m/h is down to, tail rocker is opened in place, and raw material system stops feeding, and spare unit chassis is put off on sintering machine table top.
7) 43# chassis is sling with 50t cranes, put off on sintering machine table top, sling spare unit chassis and put off in sintering board
On track road, the sintering deposit on 43# chassis is poured on spare unit chassis, tail rocker return.
8) master control room tissue raw material system starts feeding again, and gas for ignition flow returns to 920m/h, main exhausting door by
Step returns to 100%, slings 43# chassis and leaves sintering machine table top.
9) sintering machine reruns, and resumes production.It is 15 minutes to amount to downtime.
