According to the installation diagram of whole annular furnace furnace shell, Unified number is carried out to every block annular furnace furnace shell, check the linear dimension of monolithic furnace shell, deformation extent, the welding quality of anchoring piece; Annular furnace furnace shell inspect for acceptance qualified after every block furnace shell kept flat construct on the ground;
B, anchored brick are installed
Find out the structure of refractory of corresponding burner according to annular furnace furnace shell numbering, then install anchored brick according to burner structure of refractory figure, anchored brick will be installed firmly perpendicular to furnace shell; C, mould, formwork erection
Burner mould installation dimension is accurate, firm, twines scratch 1mm thickness asphalt paper after installing at burner mould, is convenient to remove mould; Surrounding model sheetinstallat accurately, firmly, and in template brushing releasing agent;
D, refractory material casting and maintenance
The refractory material of burner is castable structure, and during refractory material casting construction, vibration compacting, guarantees that anchored brick is perpendicular to furnace shell, and makes surrounding template indeformable; After castable solidifies 24 hours, remove mould, template, and castable natural drying maintenance is after 48 hours, can install with furnace shell;
E, refractory material casting are fit into annular furnace furnace wall with furnace shell
Strictly carry out the installation of annular furnace furnace shell by annular furnace furnace shell erection sequence and corresponding annular furnace furnace shell numbering, during installation, furnace shell avoids concuss and shock.
The refractory material off-line pouring procedure of annular furnace burner of the present invention can also be further achieved by the following technical measures.
Aforesaid method, in wherein said step b, at the asphalt caulk of its external coating 1mm thickness after anchored brick installation.
After adopting technique scheme, the refractory material off-line pouring procedure of annular furnace burner of the present invention has the following advantages:
1, making step is reasonable in design, simple to operate;
2, without work high above the ground, construction quality easily controls, safe and reliable;
3, reduce engineering cost, the construction cost of the refractory material off-line pouring procedure of annular furnace burner of the present invention is online 1/3, and engineering time of single burner refractory material is online 1/2.
