Abstract
The invention relates to a steel wire rope head casting method which is characterized in that tin-based bearing alloy is fused, zinc-based complex adhesion promoters are prepared to be used; rope heads at two ends of a steel wire rope are divided into completely divergent broom heads, and the broom heads are washed through steams, blown dry through high pressure wind and placed into the fused bearing alloy for preheating for 40-75s; after preheating, the zinc-based complex adhesion promoters are evenly coated on each steel wire of the broom heads; the broom heads coated with the adhesion promoters are placed into the fused bearing alloy again, evenly stirred and taken out, the broom heads coated with the alloy in advance are placed into a casting mold for casting of conical heads. The steel wire rope head casting method has the advantages of being simple in process, environmentally friendly and fast and convenient to operate, being capable of well ensuring the rope head casting quality and being favorable for overall pulling breaking measurement and detection of the steel wire rope.
Description
Technical field
The present invention relates to a kind of casting of metals method, particularly a kind of cable wire end casting method belongs to metallic article inspection technology field, is used for that steel wire rope is whole to pull open disconnected mensuration check.
Background technology
Steel wire rope generally all uses in very abominable working environment, and all technical of steel wire rope will affect its service life.Thereby the mensuration check of carrying out the whole rope rupture pull force of steel wire rope sample is very important.China Patent Publication No. CN101829764A for example, open day on September 15th, 2010, invention and created name is a kind of molten metal casting method for cable wire end, this application case discloses the hot casting mode of a kind of employing, cut the steel wire rope of certain-length, steel wire rope end head is made the broom head shapes and carried out surface treatment, alloy molten solution with uniform temperature and certain mass proportioning is cast into cone shape with steel wire rope broom head, form test specimen after the casting cooling, thereby carry out the casting method of overall breaking force of steel wire rope test.Its weak point is:
The one, after the broom head of steel wire rope cleans and adopts steam or boiling water once to clean, carry out secondary cleaning with diesel oil or gasoline again, after broom head drying, in containing the hydrochloric acid solution of zinc, immersed 2～3 minutes, should cast immediately after the pickling, to reduce steel wire rope surface corrosion degree.The method needs the plenty of time on the one hand, can not in time carry out the whole disconnected test of pulling open to steel wire rope.On the other hand, use the very strong hydrochloric acid solution of corrosion, can damage steel wire rope to be checked, affect the true pulling force of steel wire rope, simultaneously environment, operator ' s health are all had harmful effect.
The 2nd, the molten alloy of broom head casting needs to prepare by the special ratios in the application case, not only needs the metallurgical smelting technology of specialty, and the difficult control of its alloying component, can not guarantee well broom head casting quality.Simultaneously, cast temperature reaches 450 ± 10 ℃ of summers, 480 ± 10 ℃ of winters, and the temperature more than 400 ℃ will produce fire damage to carbon steel material, thus affect the whole rupture pull force test value of steel wire rope.
Summary of the invention
The object of the invention is to: for the deficiency in the above-mentioned technology, provide the simple environmental protection of a kind of technique, easy to operate quick, can better guarantee fag end casting quality, be conducive to whole broken the drawing of steel wire rope and measure the cable wire end casting method of checking.
The present invention adopts following technical solution for achieving the above object:
A kind of cable wire end casting method the steps include: first the karmarsch alloy melting, and modulation zinc ammonia complex adhesion promoter is stand-by; Then steel wire rope two ends fag end is splitted into the fully broom head of fork, the broom head dries up with high-pressure blast after steam flush, and puts into the bearing metal preheating of melting, is controlled at preheating time between 40～75s; After the preheating zinc ammonia complex adhesion promoter is coated in equably on each root steel wire of broom head; The broom head that then will scribble adhesion promoter is put into the bearing metal of melting again, takes out after evenly stirring, and the broom head that then will coat in advance alloy is put into casting die, carries out the casting of conical head.
Further scheme is, described karmarsch alloy is selected the trade mark to be ZChSnSb8-8 or to be the bearing metal of ZChSnSb11-6; Described zinc ammonia complex adhesion promoter is modulated by the proportioning of 2:1 by zinc chloride and industrial ammonia and is formed; The alloy casting temperature is controlled at 320 ± 10 ℃.
Beneficial effect of the present invention is: by set zinc-coated ammino-complex adhesion promoter technique in the cable wire end casting process, clean to simplify the broom head, do not use diesel oil or gasoline to carry out secondary cleaning, do not use and keep somewhere the hydrochloric acid solution with severe corrosive, the molten alloy of broom head of casting simultaneously adopts commercially available karmarsch alloy, cast temperature is greatly reduced, the cast alloys quality can effectively be controlled, steel wire on alloy in the alloy conical head and the broom head is bonding firmly, test is reliable, saves casting time.Therefore, the present invention has the simple environmental protection of technique, easy to operate quick, can guarantee preferably fag end casting quality, is conducive to whole broken the drawing of steel wire rope and measures the advantage of checking.
The specific embodiment
Below by specific embodiment the present invention is elaborated.
The specific embodiment of the invention is: a kind of cable wire end casting method comprises molten alloy, allocates adhesion promoter, tears the broom head open, the processing steps such as the decontamination of broom head and preheating, broom head coating adhesion promoter, broom head precoating alloy, cast alloys conehead.
The concrete technological process of the present invention is:
A, molten alloy, first that the karmarsch alloy melting is stand-by, and described karmarsch alloy to select the trade mark be ZChSnSb8-8 or be the bearing metal of ZChSnSb11-6;
B, allotment adhesion promoter carry out hybrid modulation with zinc chloride and industrial ammonia by the proportioning of 2:1, and it is stand-by to form the zinc ammonia complex adhesion promoter;
C, tear the broom head open, steel wire rope sample two ends fag end is splitted into the fully broom head of fork;
The decontamination of steam flush broom head is used in d, the decontamination of broom head and preheating, and dries up broom head ponding with high-pressure blast, then the broom head is put into the bearing metal preheating of melting, is controlled at preheating time between 40～75s;
E, broom head coating adhesion promoter after the preheating of broom head, are coated in the zinc ammonia complex adhesion promoter on each root steel wire of broom head equably;
F, broom head precoating alloy are put into the bearing metal of melting again with the broom head that scribbles adhesion promoter, take out after evenly stirring, and reach the purpose of precoating alloy;
G, cast alloys conehead are put into casting die with the broom head that coats in advance alloy, carry out the casting of conical head.
