Abstract
The utility model provides a dry quenching stove bracket inside lining carries out staggered distribution drilling at the bracket firebrick surface at inside lining damage position, buries heat-resisting expansion bolt underground in the drilling, welds the heat-resisting grab nail of different length on the heat-resisting expansion bolt, is equipped with the resistant firebrick outside at heat-resisting grab nail position and pours wear-resisting castable. The utility model discloses can avoid the firebrick of bracket and upper portion inner ring wall all to demolish the rebuild, the overhaul period is shortened, reduces cost of maintenance, effectively improves bracket inside lining bonding strength, avoids appearing the phenomenon of collapsing, prolongs the life of bracket.
Description
Technical field
The utility model belongs to coking equipment field more particularly to a kind of coke dry quenching furnace bracket liner.
Background technique
Currently, domestic existing coke dry quenching furnace bracket is made of refractory brick, and such masonry construction, globality poor,
The shear stress that " bracket " is generated by inner ring wall volume expansion under the condition of high temperature, before stress concentrates on two rows bricks, " ox
Leg " easy fracture falls off.During brick, the selection requirements of fire clay are higher, and chamotte hardening strength is lower in masonry, nothing
Method bonds completely, since adhesive bending strength is low, be easy to produce between brick and brick and adjacent two layers brick layer between slide, Wu Fabao
Mortar joint design requirement is demonstrate,proved, after baker expansion uniformly sexually revises, the stress of generation can not be eliminated, and chute brick and top form and squeeze,
The impaired fracture of vulnerable area brick body is caused, bracket service life is influenced, restricts the dry raising for putting out rate.
Summary of the invention
The utility model is intended to provide a kind of avoidable bracket and further damages, and improves bracket service life, reduces maintenance
The coke dry quenching furnace bracket liner of cost.
For this purpose, the technical solution that the utility model is taken are as follows:
A kind of coke dry quenching furnace bracket liner is changed to refractory brick by refractory brick masonry construction for bracket damage of internal lining position
Make the pouring structure of skeletal support, castable and anchoring piece as surface protection；In the bracket refractory brick table of liner damaged location
Face carries out stagger arrangement distribution drilling, buries resistance to thermal expansion bolt in drilling, heat-resisting bitch is welded in resistance to thermal expansion bolt, is equipped with heat-resisting
Wear-resistant castable is poured outside the refractory brick at bitch position.
The utility model has the following beneficial effects:
The utility model can avoid ringwall refractory brick in bracket and top, and all dismounting is built again, is shortened maintenance duration, is reduced
Maintenance cost effectively improves bracket liner adhesion strength, avoids the occurrence of phenomenon of collapsing, extends the service life of bracket.
Detailed description of the invention
Fig. 1 is coke dry quenching furnace bracket inner lining structure schematic diagram.
In figure: refractory brick 1, resistance to thermal expansion bolt 2, heat-resisting bitch 3, wear-resistant castable 4.
Specific embodiment
The utility model coke dry quenching furnace bracket liner builds knot by original refractory brick 1 for bracket damage of internal lining position
Structure, is changed to refractory brick 1 and makees skeletal support, wear-resistant castable to pour with resistance to thermal expansion bolt 2, heat-resisting bitch 3 as surface protection
Building structure.Stagger arrangement distribution drilling is carried out on 1 surface of bracket refractory brick of liner damaged location, buries resistance to thermal expansion bolt in drilling
2, the heat-resisting bitch 3 of different length is welded in resistance to thermal expansion bolt 2, is poured outside the refractory brick 1 equipped with heat-resisting 3 position of bitch resistance to
Castable 4 is ground, the seamless bracket liner of pouring structure is formed.
