Background technology
Coldplate is the equipment that cooling is provided for the metallurgy high temperature stove, can protect the metallurgy high temperature stove to avoid the erosion and the mechanical wear of high temperature fluid in the body of heater, prolongs the metallurgy high temperature stove life-span, guarantees its safety and stability production.In a single day cooling device goes wrong, and the metallurgy high temperature kiln is stop production to overhaul comprehensively, will bring heavy economic losses.So the life-span of the life-span of coldplate and performance decision metallurgy high temperature stove is metallurgy high temperature stove long-service life high-efficiency, energy-conservation important assurance.
The coldplate material that current domestic and international metallurgical industry is generally adopted is based on cast iron and rolling fine copper, and still, there are many deficiencies in cast iron or rolling fine copper coldplate.With most popular spheroidal graphite cast-iron cast steel cooling plate is example, it has the following disadvantages: (1) spheroidal graphite cast-iron cast steel cooling plate must add anti-carburization coating outside the cooling duct, make between passage and the matrix and form air gap, and air gap makes the coldplate heat transmission resistance increase more than 1,000 times, worsen the heat-transfer effect of coldplate, increase coldplate working face temperature, quicken the breakage of coldplate; (2) be covered with the globular graphite (particle diameter 0.025～0.150mm) that varies in size on the spheroidal graphite cast-iron matrix, countless small holes have been equivalent to form after globular graphite is oxidized, constituted the cradle that crack and crackle take place, quickened the expansion of crack and crackle, thereby cause coldplate to shorten service life, increase resource consumption, be unfavorable for coldplate longevity, energy-conservation; (3) when the large-scale spheroidal graphite casting of casting, C, S, P are pushed to liquid zone easily in the column crystallization process, form a segregation thing enrichment region in center equiax crystal district, the percentage elongation at cast(ing) surface and center is existed than big-difference, the surface percentage elongation is greater than the centre more than one times, promote the generation and the expansion of spheroidal graphite cast-iron crack or crackle, be unfavorable for coldplate longevity; (4) linear expansion coefficient of spheroidal graphite cast-iron is more steady in variation below 600 ℃, but more than 600 ℃ then the rising with temperature rapid irreversible " growth " takes place, when temperature during greater than 709 ℃ matrix phase transformation has taken place, the coefficient of expansion and internal stress sharp increase, its breakage speeds up; (5) spheroidal graphite cast-iron thermal conductivity and thermal shock resistance are all relatively poor, and its thermal conductivity factor only is 30wm
-2K
-1, be unfavorable for the efficient cooling of coldplate.
Though and the rolling coldplate good heat conductivity of fine copper requires harshness to matrix material, complex manufacturing costs an arm and a leg.In actual applications, after the rolling coldplate hot side of fine copper slag crust peeled off, a large amount of heats of metallurgical furnace kiln strip that is cooled was walked, and also existed and freezed the possibility in metallurgy high temperature stove molten bath; And after its hot-face temperature surpassed 200 ℃, the tensile strength of matrix material descended rapidly.
The utility model content
In order to overcome the problem that prior art exists, the purpose of this utility model is to provide the new cast steel substrate material of a kind of usefulness to replace the cast steel cooling plate of traditional cast iron materials, cooling water pipe and matrix are combined closely, eliminated air gap, improved cast steel cooling plate performance, prolong service life of metallurgy high temperature stove.
For achieving the above object, the utility model is to realize by following technical scheme:
A kind of cast steel cooling plate, comprise cooling plate base body and cooling water pipe, it is characterized in that described cooling plate base body and cooling water pipe all made by cast steel material, cooling plate base body is a U-shaped, cooling water pipe is positioned at cooling plate base body, fit tightly with cooling plate base body, stretch out from two ends of the U-shaped of cooling plate base body at its two ends.
The cross section of aforesaid cooling water pipe is oval, and the length ratio of oval-shaped major axis and minor axis is 0.5～0.7.
Be with pipe box on the outer surface of aforesaid cooling water pipe and cooling plate base body contact site, be used to protect cooling water pipe.
Aforesaid cast steel cooling plate is characterized in that described cooling water pipe is many, only shows little melting in casting process, and remelting and crystallization more do not take place substantially, is keeping the original good rolling performance of cooling water pipe.
The beneficial effects of the utility model are: the utility model adopts cast steel material to substitute existing cast iron and pure copper material is made coldplate, can effectively avoid producing air gap between cooling plate base body and cooling water pipe, prolonged the life-span of cast steel cooling plate life-span and then prolongation metallurgy high temperature kiln, saved production cost; And make cooling water pipe and cooling plate base body combine closely, improve steel brick cooling effect, improve the mechanical performance of cast steel cooling plate.
