Abstract
The utility model provides an electric conduction copper water-jacket which is used for a metallurgical furnace and a high temperature furnace. The electric conduction copper water-jacket comprises a copper base body, a water cooling channel which is arranged in the copper base body, a water inlet pipe and a water outlet pipe, wherein the water inlet pipe and the water outlet pipe are communicated with the water cooling channel, and an integrated whole structure is formed by the water cooling channel, the water inlet pipe, the water outlet pipe and the copper base body. Procedures that the water inlet pipe and the water outlet pipe are connected with the water cooling channel and the copper base body in a welding mode are avoided. The problem of water leakage in a welding process is avoided. The water cooling channel can be once formed. Cooling effect is improved through the direct connection between cooling water and the copper base body, and service life of the electric conduction copper water-jacket is prolonged. The copper base body is mixed with phosphorus, magnesium, arsenic and yttrium, and therefore density of the copper base body is strengthened effectively, copper crystal is thinned, and electric conductivity and heat-conducting property of copper are improved.
Description
Technical field
The utility model belongs to metallurgical technology field, relates to a kind of high-power cooling device, relates in particular to a kind of for the conductive copper water jacket on metallurgical furnace, the high temperature furnace.
Background technology
Be applied at present the conductive copper water jacket on metallurgical submerged-arc furnace, the high temperature furnace, its built-in cooling water channel is to adopt in the boring of copper matrix to make or the casting of built-in copper pipe is made, the Copper Water Jacket shortcoming of these two kinds of explained hereafter is: the Copper Water Jacket cooling water channel that (1) punching is made is less, and corner all is rectangular-shaped, has the current dead angle, cooling water flow is little, resistance is large, and jacket water temperature is high, and heat dispersion is poor, easily arcing affects conductance and service life in the use procedure.(2) built-in steel pipe, the water jacket of copper pipe casting, in casting process, reduced the temperature of copper water, caused that the water jacket matrix made and steel pipe copper tube channel are molten not to be integral, thereby produced pore, sand holes etc., packing is also poor, cracking in use appears easily, fall the phenomenons such as piece, and the conductive and heat-conductive rate variance, service life is short.
The utility model content
The purpose of this utility model is for problems of the prior art, provides a kind of heat conduction efficiency height, long service life, safe and reliable Copper Water Jacket.
Copper Water Jacket of the present utility model comprises the cooling water channel in copper matrix, the copper matrix and the water inlet pipe, the outlet pipe that are communicated with cooling water channel.Wherein cooling water channel, water inlet pipe, outlet pipe and copper matrix are the integral type overall structure.
Described cooling water channel is " U " type or " W " type, with the heat exchange area of increase water jacket, thereby improves heat exchange efficiency.
The relative prior art of the utility model has following having a few:
1, cooling water channel and water inlet pipe, outlet pipe are the integral type cast structure, have avoided the operation of water inlet pipe, outlet pipe and cooling water channel and copper matrix welding, have stopped the problem that welding is leaked; The cooling water channel once-forming, cooling water directly contacts with the copper matrix, has submitted cooling effect to, has prolonged the service life of water jacket.
In order to strengthen the density of copper matrix, the crystallization of refinement copper improves conductance and the heat conductivility of copper, add phosphorus, magnesium, arsenic, yttrium in the described copper copper matrix, and the quality percentage composition of each composition is:
Phosphor-copper: 0.15-0.25%, magnesium: 0.001-0.002%, arsenic: 0.001-0.002%, yttrium: 0.015-0.020%.
Description of drawings
Fig. 1 is the structural representation of the utility model " U " type Copper Water Jacket;
Fig. 2 is the structural representation of the utility model " W " type Copper Water Jacket.
The specific embodiment
Be described in detail below by structure and the casting technique of specific embodiment to the utility model Copper Water Jacket.
(1) preparation of sand core cooling water pipe: employing clay core sand is prepared into the cooling water pipeline of " U " type or " W " type, and at the high temperature resistant cast paint of cooling water pipeline outside coating.Cooling water channel corner all adopts designed arc-shaped appearance, and current are unimpeded, and non-resistance is further submitted cooling effect to.
(2) preparation of deoxidized cooper alloy water: adopt first traditional " poling method " that the copper water of melting is carried out deoxidation, add successively again phosphorus, magnesium, arsenic, yttrium, obtain the copper alloy water of melting; The quality percentage composition of composition of respectively mixing in the described copper alloy water is:
Phosphor-copper: 0.15-0.25%, magnesium: 0.001-0.002%, arsenic: 0.001-0.002%, yttrium: 0.015-0.020%.
In order further to improve the quality of copper alloy water, when melting copper water, pass into inert gas in the refining furnace, to remove oxide, sulfide and the dissolved gas in the copper water.
(3) cast of Copper Water Jacket: the two ends at the sand core cooling water pipe are fixedly connected with respectively water inlet pipe and outlet pipe, place in the water jacket casting cavity, inject the deoxidized cooper alloy water of 1120 ℃-1140 ℃ of implantation temperatures in the water jacket casting cavity, until casting complete; Naturally after the cooling, remove the interior water channel sand core (not having the sand core material in the finished product) of copper matrix with snakelike brill and air pressure pump, cooling water channel is shaped, and the Copper Water Jacket preparation is finished.
The Copper Water Jacket of above-mentioned preparation, its structure comprise the cooling water channel 3 in copper matrix 1, the copper matrix and water inlet pipe 2, the outlet pipe 4 that is communicated with cooling water channel 3, and cooling water channel 3, water inlet pipe 2, outlet pipe 4 and copper matrix 1 are the integral type overall structure.Cooling water channel is " U ", " W " or serpentine, has increased the heat exchange area of water jacket, thereby improves heat exchange efficiency.
The technical performance index of the Copper Water Jacket (THZD type) of the utility model casting sees Table 1.
The technical performance index of the THZD type energy Copper Water Jacket of table 1 the utility model casting
