Abstract
The invention relates to the technical field of repairing of calcium carbide pots, in particular to a method for repairing and recycling a calcium carbide pot. The method comprises the following steps of: 1, manufacturing a circular middle plate of which the diameter is greater than that of the pot bottom of the calcium carbide pot by using a waste middle plate, and paving a layer of coke powder or semi coke powder on the circular middle plate; and 2, uniformly placing the calcium carbide pot of which the bottom is damaged on the circular middle plate on which the coke powder or the semi-coke powder is paved, fixedly connecting the calcium carbide pot and the circular middle plate in a spot welding mode, and filling waste electrode paste powder into the cracked part and/or burn-through part of the calcium carbide pot. The method slightly pollutes environment, and is low in cost, and suitable for large calcium carbide production enterprises; the calcium carbide pot which is repaired by the method can be used for a long time; and if the calcium carbide pot is burned through, the burn-through calcium carbide pot can also be repaired by the method, so that the electrode paste can be stacked, the cost of cast iron materials which are used by repairing the calcium carbide pot can be saved, the cost is saved, the utilization rate of waste is improved, and the service life of the calcium carbide pot can be prolonged.
Description
Technical field
the present invention relates to calcium carbide pot recovery technique field, is a kind of restorative procedure of calcium carbide pot repairing and reusing.
Background technology
in calcium carbide production process, cast iron calcium carbide pot is the come out of the stove container of calcium carbide of splendid attire.Melting high-temperature liquid state calcium carbide is emitted in electric furnace, is responsible for shipment by the calcium carbide pot being arranged in before furnace of calcium carbide.It is cooling that calcium carbide pot goes cooled region to carry out by dolly by track carrying.Produce a large amount of high-temperature gases when liquid calcium carbide is accompanied by when emitting in stove, very easily make with this understanding cast iron calcium carbide pot damage.Especially easily burn calcium carbide pot bottom, may cause liquid calcium carbide to flow out outside pot, causes trolley track to damage, and loses calcium carbide output simultaneously.Burn or the calcium carbide pot reparation of ftractureing re-uses for bottom, domestic unified restorative procedure is to carry out casting again according to original the bottom of a pan size at present, buys a large amount of cast iron materials as for subsequent use, and expense is huge.Or use coke powder or Ramsbottom carbon powder place mat in calcium carbide pot bottom, carry out thermal insulation protection.But owing to being subject to for a long time the distortion of the calcination the bottom of a pan and the well damage of impurity, calcium carbide pot bottom coke powder or Ramsbottom carbon powder place mat are thicker, and the volume of calcium carbide pot becomes more and more less, reduces and holds the capacity of calcium carbide, and then affect production output.
Summary of the invention
the invention provides a kind of restorative procedure of calcium carbide pot repairing and reusing, overcome the deficiency of above-mentioned prior art, its can effectively solve calcium carbide pot bottom burn or ftracture need again cast that expense is high, calcium carbide pot bottom place mat coke powder or Ramsbottom carbon powder be compared with thin or cause the bottom of a pan deformed damaged seriously or capacity diminishes and affects the problem of output compared with thick.
technical scheme of the present invention realizes by following measures: a kind of restorative procedure of calcium carbide pot repairing and reusing: carry out in the steps below: the first step: make a diameter with waste and old middle plate and be greater than plate in the circle in the calcium carbide pot the bottom of a pan, layer overlay coke powder or Ramsbottom carbon powder on plate in circle; Second step: smooth being placed on of calcium carbide pot that bottom is damaged completed in the circle of coke powder or Ramsbottom carbon powder on plate, and calcium carbide pot is fixed together by plate in spot welding mode and circle, at the cracking place of calcium carbide pot and/or burn place and fill waste and old electrode paste powder; The 3rd step: now calcium carbide pot is put into the environment of temperature 300 DEG C of left and right, electrode paste powder just can become liquid state from bulk, the electrode paste powder of fused solution will be filled the cracking place at the bottom of calcium carbide pot and/or burn place, in the time of temperature rise to 600 DEG C degree to 1500 DEG C, electrode paste powder just can be become from plastic state solid-state, combine together with cast iron, this process is between one hour to three hours; The 4th step: insert one deck coke powder or Ramsbottom carbon powder or ashes in calcium carbide pot, plate in circle and calcium carbide pot are departed from and just can use calcium carbide pot after cooling.
in above-mentioned circle, the thickness of plate can be greater than 5mm.
the above-mentioned cracking place until calcium carbide pot and/or burn place repaired after, in calcium carbide pot, insert one deck coke powder or Ramsbottom carbon powder or ashes, the thickness of coke powder or Ramsbottom carbon powder or ashes can be 50mm to 200mm.
environmental pollution of the present invention is little, and cost is low, is applicable to large-scale calcium carbide manufacturing enterprise; Use the calcium carbide pot after the method is repaired, can life-time service, if again burnt, also can use this method reparation, both solve waste and old electrode paste and stacked problem, and saved again and repaired calcium carbide pot cast iron materials expense used, saved cost, improve salvage value, extended the work-ing life of calcium carbide pot.
Embodiment
the present invention is not subject to the restriction of following embodiment, can determine concrete embodiment according to technical scheme of the present invention and practical situation.
below in conjunction with embodiment, the invention will be further described:
the restorative procedure of this calcium carbide pot repairing and reusing carries out in the steps below: the first step: make a diameter with waste and old middle plate and be greater than plate in the circle in the calcium carbide pot the bottom of a pan, layer overlay coke powder or Ramsbottom carbon powder on plate in circle; Second step: smooth being placed on of calcium carbide pot that bottom is damaged completed in the circle of coke powder or Ramsbottom carbon powder on plate, and calcium carbide pot is fixed together by plate in spot welding mode and circle, at the cracking place of calcium carbide pot and/or burn place and fill waste and old electrode paste powder; The 3rd step: now calcium carbide pot is put into the environment of temperature 300 DEG C of left and right, electrode paste powder just can become liquid state from bulk, the electrode paste powder of fused solution will be filled the cracking place at the bottom of calcium carbide pot and/or burn place, in the time of temperature rise to 600 DEG C degree to 1500 DEG C, electrode paste powder just can be become from plastic state solid-state, combine together with cast iron, this process is between one hour to three hours; The 4th step: insert one deck coke powder or Ramsbottom carbon powder or ashes in calcium carbide pot, plate in circle and calcium carbide pot are departed from and just can use calcium carbide pot after cooling.
can according to actual needs, the reparation side of above-mentioned calcium carbide pot repairing and reusing be made further optimization and/or improvements:
as required, in circle, the thickness of plate is greater than 5mm.As required, until the cracking place of calcium carbide pot and/or burn after place repaired, insert one deck coke powder or Ramsbottom carbon powder or ashes in calcium carbide pot, the thickness of coke powder or Ramsbottom carbon powder or ashes is 50mm to 200mm.
