And continuing rotation so that upper tubing string is spun with lower tubular column.
Preferably, slips of the invention can be that, using micro-indentations slips made by steel alloy, the steel alloy is by following heavy
The component composition of amount part：C 0.17-0.19%, Si 2.1-2.5%, Cr 1.4-1.7%, Mn 2.2-2.8%, W 1.3-
1.5%th, Ti 0.06-0.08%, Mo 0.08-0.1%, Sb 0.03-0.06%, S 0.022-0.025%, P 0.012-
0.014%th, remaining is iron and inevitable impurity.Preferably, steel alloy of the invention is made up of the component of following weight portion：
C 0.17%, Si 2.2%, Cr 1.6%, Mn 2.5%, W 1.5%, Ti 0.08%, Mo 0.1%, Sb 0.06%, S
0.024%th, P 0.013%, remaining be iron and inevitable impurity.
The handling process for manufacturing the steel alloy of slips of the present invention is as follows：
(1) the good surface of the work of punching press is carried out cleaning, is polished and ungrease treatment.
(2) workpiece heat for having pre-processed to 940-945 DEG C is carried out into normalized treatment 3 hours, air is then passed to 12
615-620 DEG C is cooled in minute, and is allowed to keep temperature air cooling after 1.5 hours.
(3) carburizer is dried at 230 DEG C and is processed 2 hours.
(4) carburizer being put in the bottom of carburizer, being put the workpiece in carburizer, the top of workpiece is also placed in carburizing
Temperature in carburizer is risen to 660-662 DEG C and is incubated 5 hours by agent, carries out just oozing.Carburizing equipment must have good furnace temperature uniform
Property, sealing and atmosphere evenness, otherwise can be due to the uneven and inequality that cause amount of distortion of furnace temperature or atmosphere with furnaceman's part
It is even.
Preferably, carburizer is pressed by silica, carbon black, calcium bicarbonate, sodium acid carbonate, acetic acid formicester, butenoic acid formicester
It is 1 according to mass ratio：0.3-0.34：0.12-0.15：0.1-0.13：0.2-0.23：0.06-0.08 is well mixed and makes.More preferably
Ground, carburizer are 1 according to mass ratio by silica, carbon black, calcium bicarbonate, sodium acid carbonate, acetic acid formicester, butenoic acid formicester：
0.33：0.15：0.12：0.21：0.06 is well mixed and makes.Above-mentioned carburizer is special for the alloy composition of slips of the present invention
Door configuration, using the carburizer of the present invention, can be greatly enhanced carburizing efficiency.
(5) 810-815 DEG C is continuously heating to, is kept for 2 hours, while persistently instilling isopropanol；The infusion volume of isopropanol is
10-12 ml/mins, carbon potential are 0.8%Cp.The isopropanol being passed through decomposes at high temperature, produces active atoms of carbon, and is heated
The surface of the work of state absorbs, and backward steel alloy diffusion inside.Generally, heating-up temperature is higher, and carburizing speed is just faster, and expands
The thickness of scattered layer is also deeper.
As the flow of water, potential, potential difference determines the trend of material flowing to carbon potential.Carbon potential difference determines the side of carbon spread
To.When free diffusing, spread where carbon is always low to carbon potential from where carbon potential height.Carbon potential in heat treatment is referred in stove
When carbon-containing atmosphere reaches dynamic equilibrium at a certain temperature and the austenite of surface of steel workpiece between, what the surface of steel reached contains
Carbon amounts.It is general to be measured using mild steel thin slice.The mild steel paillon foil that thickness is less than 0.1mm is placed in into the carburizing medium of a certain temperature
In, through carburizing is carried out, the phosphorus content of paillon foil is determined, is carburizing medium carbon potential at such a temperature.
(6) 925-930 DEG C is continuously heating to, is kept for 60 hours, while persistently instilling isopropanol.During this period, front 48 is little
Shi Weiqiang oozes the stage, and the infusion volume of isopropanol is 20-22 ml/mins, and carbon potential is 1.2%Cp；It is within 12 hours diffusion phase afterwards,
The infusion volume of isopropanol is 8-10 ml/mins, and carbon potential is 0.8%Cp.
(7) 840 DEG C are cooled to stove, are passed through cold wind, temperature is rapidly decreased to 590-592 DEG C, be incubated 3 hours, then again
810-815 DEG C is warming up to, 2 hours is incubated, while persistently instilling isopropanol；The infusion volume of isopropanol is 10-12 ml/mins,
Carbon potential is 1.0%Cp.
(8) by workpiece take out be put into oil quenching, when temperature is down to 130-135 DEG C, lonneal to 190-200 DEG C,
Air cooling.Release the distortion that parts are accumulated in the sequence of operations of whole machining process to dive in quenching process
Energy；Lonneal after quenching, can also make part retained austenite be changed into martensite, and make martensite fully be changed into tempering
Martensite, so as to ensure tissue and dimensional stability.
(9) surface of the work carries out blackening process, and the principle of blackening process is to make metal surface produce layer oxide film, with every
Air, reaches antirust purpose absolutely.
After above-mentioned PROCESS FOR TREATMENT, the hardness of slips is up to 56-62HRC, and anti-wear performance has obtained greatly carrying
It is high.
It is used in hydraulic tongs using slips obtained in preparation method of the invention, enables to hydraulic tongs and holding tubing string tightly
