Background technology
Blown aluminium plate must carry out anneal to aluminium sheet before inflation, with the material internal stress that each manufacturing procedure such as hot rolling before the elimination aluminium sheet inflation, cold rolling etc. caused, material has enough plasticity when guaranteeing inflation.At present, what the blown aluminium plate method for annealing was generally selected for use is common batch annealing, adopt electrically heated, by in stove, once bearing the aluminium sheet of load quantity, annealing time is more than 12 hours, reach the annealing hardness required value, this annealing way is a kind of batch production mode, blown aluminium plate annealing is generally large batch of production operation, large batch of like this workload requires to use many box-annealing furnaces to finish simultaneously, the shortcoming of this annealing furnace is that energy consumption is big, efficient is low, labor strength is big, aluminium sheet is overlapping stacking in stove, exist heat passage inhomogeneously, the annealing hardness value is unstable and can not carry out the defective of the monitoring and measuring of hardness at any time, so can adopt a kind of continuous annealing mode to the annealing expectation of this blown aluminium plate.Seek existing continuous annealing furnace, generally all be continuous annealing at shape such as tubing, band steel etc., this continuous annealing furnace requires different because of the annealing part process, specific aims such as the structure of body of heater, size, type of heating, mode of movement are stronger, can't be applicable to anneal, and a kind of efficient e Foerderanlage that is suitable for carrying this blown aluminium plate can not be provided blown aluminium plate.
Summary of the invention
The batch annealing method is of poor quality to the blown aluminium plate annealed, hardness is inhomogeneous in order to overcome, the difficult control of hardness, energy consumption is big, efficient is low, the production cycle is long, labor strength is big deficiency, and the inapplicability of existing continuous oven, the invention provides a kind of continuous annealing method of blown aluminium plate.
The technical solution adopted for the present invention to solve the technical problems is: a kind of continuous annealing method of blown aluminium plate.
Present method adopts a kind of aluminium sheet continuous annealing furnace that comprises suspension type circulation material conveying device, comprise body of heater, heating unit, temperature control unit, have the circulation, the suspension type device for transporting objects that pass whole furnace chamber top, extension basket and conveyor chain motor that described e Foerderanlage is arranged by conveyor chain track, conveyor chain, spacing are formed, conveyor chain track part in furnace chamber fixedlys connected with body of heater, hang fixing or ground supports is fixed in the furnace chamber outside part, conveyor chain runs in the guide in the conveyor chain track, hang basket and be suspended on the conveyor chain, spacing can be regulated between the extension basket; The body of heater two ends are provided with upper and lower access bridge.Described heating unit is a natural gas burner, and described temperature control unit is made up of temperature sensor, Sweet natural gas work output controller; Described body of heater is provided with burner blower, recirculation blower.
Adopt the aluminium sheet continuous annealing furnace of this suspension type circulation material conveying device, have following technological process:
Natural gas burner is opened in heating, connects burner blower, recirculation blower power supply;
Feeding is hung basket length to aluminium sheet according to the aluminium sheet size adjustment and is steadily placed, and notes the bending direction unanimity of plate during placement, and the gap is even, does not abrade aluminium sheet, starts the conveyor chain motor;
Design temperature is set the furnace chamber temperature, when first basket of aluminium sheet enters annealing furnace, guarantees that temperature reaches set(ting)value in the stove;
Set speed setting conveyor chain motor rotary speed, the linear velocity of control conveyor chain is guaranteed the annealing time of aluminium sheet in stove.
Present method beneficial effect of the invention is: the annealing cost of a, individual blown aluminium plate of contrast that cuts down the consumption of energy, and adopting the box-type furnace method is 0.42 yuan/, adopting this continuous oven is 0.182 yuan/, so it is over half to cut down the consumption of energy; B, annealing quality are stablized vertical being placed on of aluminium sheet and are hung in the basket, and certain clearance is arranged between the aluminium sheet, and under the effect of recirculation blower, aluminium sheet is heated evenly, and has guaranteed that every aluminium sheet is consistent with each local annealing hardness on the aluminium sheet; C, the active and effective annealing way of continuous annealing furnace with short production cycle have reduced annealing time significantly, have shortened the production cycle; D, safety labor-saving A.T.C, and the workman can understand the temperature regime of aluminium sheet on the conveyor chain, avoided scald, the workman need not carry out the concentrated circulation of big batch materials, has alleviated labour intensity e, working efficiency significantly improves.
