Abstract
The invention relates to a recycling method of a waste sheet iron drum, which comprises the following steps of: firstly, manually removing an upper cover and a lower cover of the waste sheet iron drum and flatly spreading the drum into sheet-shaped iron sheet along the longitudinal direction of the sheet iron drum; placing the drum into a combustion furnace in a tunnel to burn impurities on the iron sheet out; horizontally delivering the drum to two rolling mills for hot rolling when the drum still has temperature, and then longitudinally delivering the drum to two rolling mills for cold rolling so as to remove corrugations; manually removing oxidized skin after removing the corrugations for two times; removing the oxidized skin again by acid cleaning with hydrochloric acid in an acid cleaning pool; placing the iron sheet after acid cleaning in a clear water pool and then repeatedly cleaning the iron sheet to remove acid matters; placing the iron sheet in an industrial sodium nitrite neutralization pool to remove acid matters again; placing the iron sheet of which the acid matters are removed for two times in a double-row four-roll two-brush machine to remove acid and alkali residues with clear water; then delivering the iron sheet to a four-roll press machine for rolling to remove the corrugations for the third time; leveling the iron sheet of which the corrugations are removed for three times in a leveler; and finally, classifying and packing the leveled iron sheet and then putting the iron sheet in storage.
Description
Technical field
The present invention relates to a kind of method of disposal of waste and old iron sheet pail pack, particularly a kind of regeneration processing method of waste and old iron sheet pail pack.
Background technology
For a long time, most oils, industrial chemicals, especially pitch are for ease of storing and transporting and all use the iron sheet pail pack.Although so well solved their storage and transportation; but after their content is used up; these iron sheet pail packs are just arbitrarily thrown away it by the user and are got over; with various waste and old oil drums; the pitch bucket is thrown in the field, wilderness; the roadside; distribute various unpleasant stinks; jeopardize people's healthy and pedestrains safety; through Exposure to Sunlight for a long time; wind; in the mashed soil of the rust that drenches with rain; influence environment and soil, the residue of their internal memory things immerses soil, or flows into rivers through rainwater; the pond; in the well; cause soil; the environmental pollution at water source; both directly jeopardize people's life, be unfavorable for environmental protection again, caused the waste of sheet metal simultaneously.
Summary of the invention
The objective of the invention is to for overcoming the deficiencies in the prior art; a kind of waste and old iron sheet pail pack regeneration processing method is provided; make waste and old iron sheet pail pack reclaiming utilization; elimination is to the pollution to environment; be beneficial to environmental protection and personal safety; reduce the waste of metal material, reduce material cost.
The present invention has adopted following technical scheme for overcoming the deficiencies in the prior art: a kind of waste and old iron sheet pail pack regeneration processing method is characterized in that processing step is as follows:
1), with the loam cake and the lower cover of artificial removal waste and old iron sheet barrel, open along vertically cutting of iron sheet barrel and to shakeout that to be tabular iron sheet standby;
2), aforesaid iron sheet is put into the tunnel combustion furnace, under 200-400 ℃ temperature, with 16-25 rice/minute transfer rate burning one minute, the foreign material on the burning-off iron sheet;
3), with the iron sheet of burning-off foreign material all the other warm 180-200 ℃ the time, laterally sending into roll-force is 50 tons, mill speed 8-15 rice/minute the two-roller mill hot rolling, remove the iron sheet ripple for the first time;
4) after the iron sheet of removing ripple, for the first time cooled off naturally, it is vertically sent into roll-force was 50 tons, mill speed 16-24 rice/minute two-roller mill cold rolling, remove the iron sheet ripple second time;
5), the iron sheet with twice removal ripple carries out artificial descaling for the first time;
6) iron sheet after descaling, is for the first time put into pickling tube, with percent concentration be 31.2 carried out descaling the second time in chlorohydric acid pickling 10-20 minute;
7), the iron sheet after the pickling puts into clear water reserviors, cleans disacidify matter repeatedly 3-5 time;
8), the iron sheet after clear water cleaned puts into GB/T2367-90, in the industrial sodium nitrite neutralization pond of percent concentration 5/,100 5 minutes, disacidify matter once more;
9), the iron sheet after twice removal acid matter is put into double four rollers, two brush machines and is removed acid, alkali residue with 8 meters/minute speed scour without sediment motion;
10), to send into roll-force be 300 tons for the iron sheet of removing acid, alkali residue, mill speed be 10-22 rice/minute four roller pressure machines rolling, it is removed ripple for the third time;
11), put into levelling machine and smooth through removing iron sheet behind the ripple for three times;
12), the warehouse-in of the iron sheet class wrapping after the smoothing.
Iron sheet light by the waste and old iron sheet pail pack after the waste and old iron sheet pail pack regeneration disposal methods provided by the invention is smooth as new; the unrest of having stopped waste and old iron sheet pail pack is got rid of and is thrown out without care; make the iron sheet of waste and old iron sheet pail pack obtain the reclaiming utilization; can be used for making the raw material of farm machinery product; cold rolling the pulling of this material needs 5000 yuan/ton; and the iron sheet that obtains through the present invention only is 3000 yuan/ton; therefore; not only eliminate pollution environment; be beneficial to environmental protection and personal safety; and the waste of minimizing metal material, reduce material cost.
