Background technology
Tertiary air tube shut-off device is mainly used in new dry cement production technology high temperature wind（Tertiary air）Amount regulation, category control
Element processed.It can adjust the air quantity of tertiary air, ensure the job stability and high efficiency of dore furnace.It is special as tertiary air damper
Castable, it is desirable to possess that resistance to elevated temperatures is good, and spalling resistance is good, resistance to powder erosion is strong, and chemerosiveness resistent is strong
And the long-life.
Castable is also known as castable refractory, is one kind granular and powdery made of refractory material adds a certain amount of bonding agent
Material, there is the unshape refractory compared with high fluidity, being molded with pouring type.Due to constructing, quilt easy to make is used extensively
In make it is large-scale or can not mechanical pressing refractory product in terms of.And the matter of the tertiary air tube shut-off device on present cement kiln in use
Amount does not reach performance requirement mostly, its service life and using effect is not reached requirement, low intensity not resistance to erosion or disconnected occurs
Split, do not have the control and regulation to entering dore furnace tertiary air.Often result in and stop kiln maintenance.The appearance for causing this problem is such
In the product of moulding by casting there is such or such deficiency in the selection of material or manufacturing technology, therefore, the problem is novel dry
Method cement kiln need to urgently put the axe in the helve.
The content of the invention
