Abstract
The utility model discloses a cooling water jacket for a high-temperature smelting unit. The cooling water jacket comprises a plate-shaped water jacket body and a preformed alloy pipe cast in the water jacket body, wherein the cooling fluid can flow from the inlet of the alloy pipe into the water jacket body and can be exhausted from the outlet of the alloy pipe. Besides, the utility model also provides a high-temperature smelting unit with the cooling water jacket. Accordingly, the cooling water jacket overcomes the disadvantages of easy water leakage, high thermal conductivity, easy scale formation and high difficulty of manufacturing process due to the low melting point in the prior purely copper water jacket, and has the advantage that the service life is prolonged.
Description
Technical field
The utility model relates to metal smelt and chemical field, particularly relates to a kind of high temperature smelting equipment cooling jacket of using and the high temperature smelting equipment with it.
Background technology
Condition of work is abominable in the smelting furnaces such as existing for example flash stove, blast furnace, and temperature is up to 1300 ℃-1600 ℃ in the stove.Thus, furnace lining must bear simultaneously that high temperature gas flow washes away, the erosion of the wearing and tearing of furnace charge and slag etc.Therefore, the protection to furnace lining has proposed higher requirement.In the prior art, between laying bricks, bury fine copper material cooling jacket usually underground, force cooling thereby need carry out, to alleviate furnace lining wearing and tearing and corrosion to the furnace wall.
Germany MANGHH company has developed a kind of copper cooling jacket that is used for blast furnace in 1979.Since the copper cooling jacket cooling effect superpower to furnace lining, thus the furnace lining surface can be cooled off rapidly, and the slag that contacts with this furnace lining surface is cooled off rapidly, and form slag crust apace.At high temperature, this slag crust is farthest protected furnace lining.At present, on blast furnace, begun extensively to install the copper cooling jacket.Copper cooling jacket manufacture method mainly contains following two kinds: rolled copper slab boring formula manufacture method and pre-buried copper pipe cast copper formula manufacture method.The manufacture method of existing copper cooling jacket is described below in conjunction with Fig. 1.
The manufacture method of rolled copper slab boring formula copper cooling jacket be with copper ingot rolling in advance for sheet material 101 ', carry out boring with lathe by the water route trend again and bore, to obtain this copper cooling jacket 100 ', be formed with through hole 102 ', 103 ' on the described copper cooling jacket 100 ', as shown in fig. 1.Except that water inlet, water outlet through hole, remaining hole is sealed.This water jacket is copper closely knit, and defective is few, the thermal conductivity height.But the end socket (not shown) of described sheet material 101 ' need be handled, otherwise, there is infiltration in end socket, leaks under hot environment possibility.Because boring formula water jacket upper cover is a lot, a cooling water that has is with more than 8～10 through hole need seal obstruction.Even and under the normal temperature state, detect leak qualified, blast furnace up to more than 1300 furnace body temperatures of spending under, under elevated temperature heat extension effect, can leak again.In addition, there is following defective in the manufacturing technology of this boring copper cooling jacket 100 ': at first, the shortcoming that adopts boring to form the cooling duct is freely to arrange the cooling duct in wall body; Secondly, " boring ", " adapter ", " plug-hole " machining cost are very big; Once more, holing and adding trade union produces a large amount of copper scales, and this will increase the cost of copper cooling jacket, and the recovery of copper scale simultaneously reaches to utilize again wants consumes energy.
On the other hand, in the manufacture method of pre-buried copper pipe cast copper formula water jacket, the shaping of at first pure copper tube being prebended is put into sandbox again with the cast molding of copper water.Forming requirements herein is, copper pipe is by burn through, and combines closely with watering cast copper, and do not have clearance rate and reach more than 80%.The advantage of described pre-buried copper pipe cast copper formula water jacket is that into water, outlet pipe are stretched outside stove, does not have water pipe head in stove, and reliability is big.Snakelike copper pipe is cast in the inner embedding of water jacket, so that to greatest extent with the cooling water in the copper sheathing heat transferred copper pipe.Use is the result show, this class cast copper cooling jacket is suitable with rolling copper cooling jacket cooling capacity.But, the shortcoming of this manufacture method is that the fusing point of pure copper tube is lower, and if pre-buried copper pipe the casting copper coin process in by burn through, leak because of the fine copper water jacket the is impaired ratio of blowing out overhaul of blast furnace also surpasses 27%, and there is the too high shortcoming that easily makes the water fouling of thermal conductivity in fine copper.Under the condition that the casting copper coin cracks, pre-buried copper pipe cast copper formula water jacket also can leak, and this efflorescence that will cause refractory material is expanded, and causes running the generation of major accidents such as copper.In some cases, if cooling water flows in the stove, then can cause accidents such as blast furnace blast.
Further, the too high heat conductivility of fine copper water jacket makes coolant water temperature too high easily, even causes the boiling of cooling water.And when water seethed with excitement, calcium ion in the water and magnesium ion precipitated with oxide form and produce incrustation scale.The thermal conductivity of this incrustation scale is extremely low, and this has reduced the cooling effectiveness of described water jacket, even causes the scaling loss of cooling jacket.
