Description
Technical field
The utility model relates to the blast-furnace equipment technical field, refers to particularly a kind of complex copper cooling stud.
Background technology
2000m in recent years
3above large blast furnace adopts soft water closed circulating cooling mostly, these blast furnaces are at bosh, it is cooling that the high heat load districts such as restoration of lower stack adopt copper cooling wall to carry out more, copper cooling wall due to thermal conductivity considerably beyond cast-iron cooling wall, after coming off, slag crust can form very soon the operation slag crust, generally can not damage, but in recent years due to improper use, also there is damaged situation in copper cooling wall, as document " Ma Jiwen, " research of No. five blast furnace copper cooling stave Reasons for Damages of this steel and treatment technology ", the metal world, 6 phases in 2009 " in blast furnace copper cooling stave arranged water-cooled tube because of the impact that the pressure grouting between furnace shell and cooling stave and blast furnace steel first expand, cause the water-cooled tube of blast furnace copper cooling stave by shear fracture, cut off the case of leaking, because making the steady running of blast furnace, the copper cooling wall breakage has been subject to having a strong impact on.In the situation that blast furnace copper cooling stave or cast-iron cooling wall are a large amount of damaged, blast furnace productive capacity, safety coefficient all can worsen, if especially bosh, the damaged total amount of restoration of lower stack water-cooled tube surpass 50%, also can cause that the stove skin is rubescent, bulge phenomenon, gas leakage is serious, has serious potential safety hazard.
Once copper cooling wall or cast-iron cooling wall breakage, the general copper cooling stud that adopts carries out the reconstruction of cooling power to damaged cooling wall, in the last few years, some producers, as Ma Gang, Baosteel, Wuhan Iron and Steel Plants etc. all can install at the damaged cooling wall place copper cooling stud additional in the stove labour later stage, recover cooling performance with lower cost, extend blast furnace work-ing life, this method has obtained certain effect, but effect is also not obvious sometimes, in the situation that the copper cooling stud has been installed, can not form in time the operation slag crust, perhaps form after slag crust unstable, slag crust very easily comes off, and also there is the situation of damage in the copper cooling stud of installing, cause need to be in the perforate of stove skin when the copper cooling stud is installed, quantity more than one is installed and will significantly reduces stove skin intensity, in the situation that the copper cooling stud can not play one's part to the full, the stove skin is especially easily rubescent, cracking, this has caused great hidden danger to production.This situation has sufficient embodiment in document " Chen Kunnan, " copper cooling stud result of use Investigation and analysis ", ironmaking, in May, 2003 ", and the document has been analyzed horse steel 2500m
