Abstract
The utility model provides a composite cooling wall, comprising a ductile iron cooling wall. A copper cooling plate is arranged on the ductile iron cooling wall, a cooling channel is arranged on the copper cooling plate. The ductile iron cooling wall is provided with a first water inlet pipe and a first water outlet pipe respectively, and the first water inlet pipe and the first water outlet pipe are connected through water pipe. The copper cooling plate is respectively provided with water inlet and water outlet pipes, the water inlet and the water outlet pipes are connected with the cooling channel. The utility model has the advantages that the ductile iron cooling wall and the copper cooling plate are made into cooling wall after being compounded, which totally solves each disadvantage in the prior art and makes the composite cooling wall have high cooling strength, meanwhile, entire or part of blast furnace without overheating cooling system is realized, which ensures that when the composite cooling wall is being used, the phenomenon that the whole composite cooling wall can not be used which is caused by the damage of the ductile iron cooling wall or the copper cooling plate can not happen with prolonged service lives of composite cooling wall and blast furnace.
Description
Technical field
The utility model relates to metallurgical equipment, is a kind of compound cooling stave that uses on blast furnace.
Background technology
The cooling stave of blast furnace generally is ductile iron cooling stave or copper cooling wall.The deficiency of this cooling stave is: when using ductile iron cooling stave, because its cooling intensity is low, so when using at high temperature positions such as blast-furnace bosh, furnace bosh, rate of decay is fast, thereby influences blast furnace campaign; When using copper cooling wall, though its cooling intensity is higher relatively, but can not do very big, and can not integral body be used for the blast-furnace tuyere band, can not solve blast-furnace tuyere band cooling wall breakage problem faster, so use ductile iron cooling stave or copper cooling wall all can not effectively improve the blast furnace furnace service life separately.
Summary of the invention
The purpose of this utility model is, a kind of compound cooling stave is provided, and makes it have the high advantage of cooling intensity, is reduced in blast-furnace bosh, the rate of decay when use at the furnace bosh position, and solves blast-furnace tuyere band cooling stave simultaneously and destroy problem faster.
The utility model for achieving the above object, be achieved through the following technical solutions: compound cooling stave, comprise ductile iron cooling stave, copper cooling plate is installed on the ductile iron cooling stave, offer cooling water channel on the copper cooling plate, first water inlet pipe and first rising pipe are installed respectively on the ductile iron cooling stave, first water inlet pipe adopts water pipe to be connected with first rising pipe, be installed into rising pipe on the copper cooling plate respectively, this water inlet pipe and water outlet pipe is connected with cooling water channel respectively.On ductile iron cooling stave part working face copper cooling plate is installed, the water inlet pipe and water outlet pipe on the copper cooling plate is in the same horizontal plane, and water inlet pipe and water outlet pipe is connected with first cooling water channel respectively.On whole working faces of ductile iron cooling stave copper cooling plate is installed, first water inlet pipe is installed in the bottom of ductile iron cooling stave, first rising pipe is installed on the top of ductile iron cooling stave, second water inlet pipe is installed in the bottom of copper cooling plate, second rising pipe is installed on copper cooling plate top, second water inlet pipe and second rising pipe pass ductile iron cooling stave respectively and place its outside, and second water inlet pipe is connected with second cooling water channel respectively with second rising pipe.Ductile iron cooling stave adopts standing bolt and round steel with being connected of copper cooling plate, and round steel is circumferentially offered several grooves, and round steel is attached on the wall of ductile iron cooling stave, and threaded hole is offered at the middle part of round steel, and standing bolt one end is inserted in the threaded hole.
Advantage of the present utility model is: ductile iron cooling stave and copper cooling plate are made cooling stave after compound, the various deficiencies that exist in the prior art have thoroughly been solved, make compound cooling stave have higher cooling intensity, realized the whole or local no overheated cooling system of blast furnace simultaneously, at blast-furnace bosh, rate of decay when furnace bosh position and blast-furnace tuyere band use reduces significantly, and because the water route is independent separately, guaranteed that compound cooling stave can not occur when using making the out of use phenomenon of the compound cooling stave of monoblock because of ductile iron cooling stave or copper cooling plate damage, prolong the work-ing life of compound cooling stave, and prolonged the blast furnace furnace service life significantly.
