Description
Technical field
The present invention relates to cathode block heater and the assemble method of cathode block and cathode steel bar.
Background technology
Cathode block rod iron group is many in aluminium electroloysis sector application, the construction of the general cathode block rod iron group of one of which
Mode is made firm by ramming cathode steel bar with cold ramming paste in the rod iron preformed groove being configured on cathode block.Cathode block is in electrolytic cell
Aluminium liquid body is played to wash away and electric action；Cathode steel bar is played the negative busbar outside the direct current export electrolytic cell in electrolytic cell
The upper effect for next electrolytic bath, forms tandem application；Cold ramming paste is one kind of carbon paste, is made as adhesive
With cathode steel bar being glued together with cathode block in 100 DEG C of ± 20 DEG C of temperature, one entirety of formation realizes the biography of electric energy
Lead.
Operation when assembling cathode block rod iron group requires higher, and the most important is exactly the temperature control of cold ramming paste
Must be at 100 DEG C ± 20 DEG C, if cool kneading is not into an entirety, if heat cold ramming paste drying is without viscosity, equally
Kneading is not into an entirety.All it is normal temperature before cathode block and cathode steel bar assembling, when 100 DEG C of ± 20 DEG C of cold ramming pastes and negative electrode carbon
When block and cathode steel bar contact with each other, the heat of cold ramming paste can be passed to cathode block and cathode steel bar quickly, at a temperature of
Drop is fast, so as to influence bonding quality, causes the voltage drop between voltage cathode carbon block and cathode steel bar to increase, produces power consumption increasing
Greatly.Especially when carrying out assembling operation in winter, the temperature drop of cold ramming paste it is especially fast, task difficulty is very big, and yield rate is low,
Considerably increase the production cost of enterprise.
The content of the invention
It is an object of the invention to provide a kind of cathode block heater, to solve cathode steel bar and negative electrode in the prior art
The problem of carbon block bonding quality is poor；Meanwhile, present invention also offers a kind of cathode block and the assemble method of cathode steel bar.
The technical scheme of cathode block heater use is in the present invention：Cathode block heater, including heating mantles
With the heater for heating cathode block, the heating mantles has the roof for being used for covering cathode block.
The heating mantles has the side wall for being used for covering cathode block end.
The heater is electric heater.
The electric heater is for sinking to the heating rod in the rod iron preformed groove on cathode block.
The heating mantles includes madial wall and lateral wall, and heat preservation sandwich layer is provided between the madial wall and lateral wall.
The heating mantles is formed by corresponding left side cover body and the docking of right side cover body.
The technical scheme of the assemble method use of cathode block and cathode steel bar is in the present invention：Cathode block and cathode steel
The assemble method of rod, this method comprises the following steps：1）, using cathode block heater cathode block is heated, institute
Stating cathode block heater includes heating mantles and the heater for heating cathode block, and the heating mantles, which has, to be used to cover
The roof of cathode block；2）Cathode steel bar and adhesive are added into the rod iron preformed groove of cathode block and is bonded.
The heating mantles has the side wall for being used for covering cathode block end.
The heater is for sinking to the heating rod in the rod iron preformed groove on cathode block.
The heating mantles is that the length direction docking by corresponding left side cover body and right side cover body along cathode block is formed.
The present invention uses above-mentioned technical proposal, and cathode block heater includes heating mantles and for heating cathode block
Heater, the heating mantles has the roof for being used for covering cathode block, when assembling cathode steel bar with cathode block, will heat
Cover is covered onto cathode block, and heater is heated to cathode block, and heating mantles can reduce heat and scatter and disappear, it is ensured that plus
Thermal effect；After cathode block is heated to design temperature, then into the rod iron preformed groove of cathode block add cathode steel bar and
Adhesive is simultaneously bonded, you can avoid, because the binder performance that the heat that cathode block absorbs adhesive is caused declines, improving cloudy
Pole rod iron and cathode block bonding quality.
