Description
Technical field
The present invention relates to a kind of manufacture method of earth electrode, particularly be coated with the manufacture method of the earth electrode of zinc layer at steel core.
Background technology
Earth electrode will be embedded in underground, because the underground element that contains multiple to corrosion of metals, the earth electrode post-etching of being driven underground is very fast.Earth electrode of the prior art; the general form of hot galvanizing or electrogalvanizing that adopts is adhered to one deck zinc in steel core surface; its corrosion rate can be slowed down relatively; but the zinc coating thickness of plating or hot dip is thinner; be several microns～100 μ m, in use protective layer is corroded very soon, causes the earthing material lifetime; thereby cause lightning disturbance, cause than large economy and lose.Simultaneously because the steel core of cathodic protection is less, extremely mechanical strength and thermal stability are lower as ground connection, and conductive capability is little, can not satisfy code requirement.
Summary of the invention
The objective of the invention is to: a kind of method of making earth electrode is provided, makes steel core and zinc layer in conjunction with tight, and can be wrapped with thicker zinc layer at steel core.
Technical scheme of the present invention is:
A kind of method of making zinc-coated grounded pole is characterized in that, this method is made of following steps successively: zinc ingot metal is heated to 450 ℃ of-550 ℃ of fusions casts the cylindricality zinc ingot metal and be cut into pieces; Extrusion die is heated to 250 ℃-300 ℃, the cylindricality zinc ingot metal is heated to 250 ℃-260 ℃; Steel core after the removing surface is put into the hydraulic press internal fixation, extrusion die is put into hydraulic press, the zinc ingot metal after will heating is then put into extrusion die, and extrusion die is taper, the conical top open-ended; With hydraulic press zinc ingot metal is covered on steel core, the steel core diameter is 8mm-25mm.
The supplementary technology scheme:
The method of described manufacturing zinc-coated grounded pole is characterized in that, the zinc coating thickness after the extruding is greater than 1mm.
The invention has the beneficial effects as follows: the present invention covers pure zinc on the steel core by heat temperature raising, steel core is combined with the zinc layer is complete, form a kind of composite construction, the two is thrown off in conjunction with closely being difficult for, can make the zinc layer thicker, and the steel that forms by this kind composite construction and the annexation conjugation between zinc is good, contact resistance is low.The present invention also rationally cooperates by steel core diameter and zinc coating thickness; thicker steel core has guaranteed the mechanical strength and the ampacity of ground connection; thicker zinc layer has good protection to steel core, has prolonged the useful life of earthing material greatly, simultaneously the negative electrode of equipment and pipeline is played the effect of protection.
