Description
Technical field
Heterogeneous metal pipe cooling wall metallurgy is buried the present invention relates to a kind of metallurgical binding casting technique, more particularly to a kind of fine copper
With reference to casting technique, it belongs to cooling wall technical field.
Background technology
Blast furnace copper cooling stave has rolling to drill and casting two kinds of forms of pipe laying.It is domestic at present rolling based on drilling form.
The cooling water channel that rolling drilling is formed, its cooling effect depends primarily on the material and quality of rolled blank.Casting pipe laying cooling wall
Water channel is the inner chamber of embedment water pipe, and its cooling effect depends on the thermal conductivity and the fusion feelings between pipe and body of pipe material
Condition.Pipe laying has three kinds according to tubing matter difference：Copper-copper pipe, copper-Monel nickel coppers pipe, copper-steel pipe.
When pipe laying material is copper pipe, because castin and body are identical materials, fusing point is identical, to casting technique requirement very
Height, controls the incorrect burn through phenomenon that copper pipe occurs, and pure copper tube is higher to the water quality requirement of cooling water, and otherwise copper is high
Thermal conductivity factor cause cooler-water temperature degree high, easy fouling, substantially reduces the cooling performance of cooling wall in water pipe, it is also possible to
Fouling position causes temperature too high, damages copper pipe.This cooling wall blast furnace at home it is considerably less.
There is following defect in fine copper rolling drilling cooling wall：It is hidden to there is weld cracking in the welding between cooling water pipe and body
Suffer from, have that limitation, profile are limited by processing technology and stock utilization is low to the path of water channel.
The content of the invention
The present invention is directed to above-mentioned the deficiencies in the prior art, there is provided it is metallurgical that a kind of fine copper buries heterogeneous metal pipe cooling wall
With reference to casting technique.
The technical scheme that the present invention solves above-mentioned technical problem is as follows：
A kind of fine copper buries heterogeneous metal pipe cooling wall metallurgical binding casting technique, comprises the following steps：
A, selection Monel (i.e. nickel copper) pipe or steel pipe are used as the heterogeneous pipe for imbedding cooling wall；
B, heterogeneous pipe is bent according to drawing requirement；
C, surface cleaning treatment is carried out to heterogeneous pipe；
Moulding is carried out after the completion of D, modelling, the pre-heat treatment is carried out to heterogeneous pipe, preheating temperature is controlled at 40-80 DEG C；
E, cast cooling wall, the copper liquid that will have been melted are poured into the die cavity containing metal tube, and pouring temperature control exists
1180-1250℃。
On the basis of above-mentioned technical proposal, the present invention can also do following improvement.
Further, the pre-heat treatment is being carried out to heterogeneous pipe using heat storage medium；In preheating, using Ti125 thermal imaging systems
Temperature to heterogeneous pipe is measured and control；In cast, pouring temperature is measured and controlled using thermocouple.
The beneficial effects of the invention are as follows：Copper in Monel (Ni-Cu alloys) pipe about containing 62% nickel and 35%, by
Can form infinitely dissolve body in copper and nickel, along with Monel pipe fusing points are high, burn through is not easy during cast, the casting for obtaining into
Product rate is high.During Copper Water Jacket is on active service, any crackle being likely to form on the softer cast copper matrix of quality is not interfered with
Although the heat conductivility of many Monel compo pipe Monel alloy higher than cast copper matrix strength and hardness is lower than fine copper, by
It is relatively thin in its tube wall, because the temperature influence in face of the hot face of cooling wall is little.
Steel pipe has high-melting-point, good comprehensive mechanical performance, while overcoming pure copper tube low intensity is susceptible to deformation
With the shortcoming that may be fused, and the yield rate of cooling wall is improve and steel pipe is more cheap than copper pipe, it is possible to decrease be produced into
This.
The preheating temperature of strict control pouring temperature and metal tube so that gapless is reached between casting body and pipe and is melted
Close, tensile test bar fracture position is in outside castin and body interface, improve the cooling effectiveness of pipe laying cooling wall；Due to pipe
Complicated shape can be bent, adding casting can manufacture complicated shape feature, solve rolling cooling wall shape and water route limitation
Limitation；Casting pipe laying cooling wall product yield is high, and manufacturing cost is lower than rolling, reduces blast furnace cost of investment.
Specific embodiment
Principle of the invention and feature are described below, example is served only for explaining the present invention, is not intended to limit
Determine the scope of the present invention.
A kind of fine copper buries heterogeneous metal pipe cooling wall metallurgical binding casting technique, comprises the following steps：
1st, the heterogeneous pipe of selection embedment：Monel nickel coppers pipe, steel pipe；
2nd, heterogeneous pipe is bent by drawing；
3rd, heterogeneous pipe is surface-treated；
4th, after the completion of modelling, moulding is carried out, carries out the pre-heat treatment, the control of pipe preheating temperature before cast to heterogeneous pipe
At 40-80 DEG C；
5th, finished product is poured into a mould, pouring temperature is controlled at 1180-1250 DEG C.
During carrying out, the heating of heterogeneous pipe uses the measurement of heat storage medium, heterogeneous pipe temperature to be adopted with control to the present invention
Use Ti125 thermal imaging systems；Pouring temperature thermocouple measurement and control.
Tension test is done in sampling after finished product, and stretch test result fracture position is in outside castin and body interface.
The copper liquid for having melted is poured into the die cavity containing metal tube, the copper metal liquid cladding being melted around pipe,
Solid-liquid interface forms very big thermograde, so as to the conduction for having heat, meanwhile, from for microcosmic angle, due to cooling wall
Thicker, the heat and time for having abundance make interface carry out the counterdiffusion of atom, so as to form a composition between body and pipe
Transition zone.This diffusion transition slice width degree reaches 40-60 μm, causes interface to form metallurgical binding, to making interface bond strength big
In the intensity of body, tension failure position is in non-interface.
The foregoing is only presently preferred embodiments of the present invention, be not intended to limit the invention, it is all it is of the invention spirit and
Within principle, any modification, equivalent substitution and improvements made etc. should be included within the scope of the present invention.
