A kind of mineral hot furnace copper cooling piece
Technical field
The utility model relates to metallurgical electric furnace equipment technical field, in particular to a kind of mineral hot furnace copper cooling piece.
Background technique
Mineral hot furnace is also known as electric-arc furnace or resistance electric furnace, mainly for the production of the production such as ferroalloy, industrial silicon, calcium carbide, yellow phosphorus
Product are also commonly called as electric furnace in the sector.Copper cooling piece is the more common water cooling protection equipment of submerged arc furnace system, and working principle is benefit
With the cooling water flowed in copper cooling piece, handed over so that carrying out a large amount of heat between furnace high-temperature flue gas, copper cooling piece and cooling water
It changes, this large amount of heat is cooled water to taking away, and protection stove inner part is not damaged under high temperature environment.
The mineral hot furnace cooling piece overwhelming majority in China is steel structure at present, but according to national industrial policies and industrial structure
The requirement of adjustment, In The Sub-mergedfurnace of The Ferroalloys develops to enlarged, totally-enclosed, automation direction, superseded in industry in recent years
12500KVA mineral hot furnace below, newly-built mineral hot furnace is all in 25000KVA or more, and trend is more and more obvious.With mine
The enlargement of hot stove, steel structure cooling piece are no longer satisfied its production requirement to a certain extent, thus external use than
More mature copper cooling piece also starts to introduce the country, although the cooling effect of copper cooling piece is than the cooling effect of steel cooling piece
Good, the service life is significantly improved, but cost is also to be greatly improved, and has biggish pressure to enterprise production and management.
That there are cooling effects is poor for current steel structure cooling piece (as shown in Figure 6), weld seam is long and it is more, be easy to happen corrosion
Damaged or cracking and the phenomenon that lead to leak, cause frequent heating blowing-out to overhaul and influence production.Current ordinary copper cooling piece is (such as
Shown in Fig. 7) it include copper cooling piece ontology, it is equipped with cooling duct in copper cooling piece ontology, cooling duct is made of multiple channel sections,
Cooling duct both ends are respectively equipped with inlet and outlet, and the cross sectional shape of each channel section is in single round hole type, water inlet and go out
Cylinder-shaped water pipe is welded at the mouth of a river.In order to guarantee the cooling effect of copper cooling piece, it is necessary to by cross sectional shape in single round hole
The diameter of type channel section increases, thus the thickness of copper cooling piece must just thicken;And common cylinder-shaped water pipe have it is certain
Wall thickness, Inlet and outlet water cylindrical tube need to be welded on the thickness direction end face of copper cooling piece ontology, therefore the thickness of copper cooling piece is more
It needs to thicken to result in the weight of copper material to greatly increase in this way, production cost also increases substantially to guarantee to weld.
