Coking knife edge web plate

Installation of furnace protection iron parts for coking knife edge web plate:

1.To avoid frequent movement of the crane and accelerate the installation progress,a comprehensive lifting method is adopted,which involves using temporary installation tools to fix the protective plate with the furnace column,and lifting both the furnace column and the protective plate simultaneously.The fixing method is to use the holes on the protective plate to fix the furnace door frame,and connect the furnace column with the protective plate using hook bolts and pressure plates.When transporting and lifting furnace columns,special attention should be paid not to increase bending.The protective plate of the regenerator is spot welded on the furnace column and also aligned with the furnace column.

2.Pressure construction technology for furnace protection iron parts.According to the design and traditional construction,the method of tightening nuts with n-shaped temporary braces is used for pressurization.It is very difficult to achieve a gap of 3mm-5mm between the protective plate and the furnace body through manual force,and it is easy to generate uneven pressurization and loose contact,leading to smoke emission from the protective iron parts during coke oven production.To reduce workload and accelerate construction progress,n-shaped card support and jack pressure construction methods can be used for pressurization.After using a jack to pressurize,the pressurization work becomes labor-saving,while improving the installation quality of furnace protection iron parts.

3.When installing the furnace door frame,attention should be paid to aligning it with the centerline of the carbonization chamber.It is strictly prohibited for the inner edge of the furnace frame to protrude beyond the protective plate,especially after tightening the top screw,attention should be paid to inspection.Therefore,temporary support should be added to the furnace frame during installation to avoid narrowing the width of the furnace frame.Special attention should be paid to strictly prohibiting the use of tightening the hook bolts to pressurize the furnace door frame.This not only does not compress the asbestos rope tightly,but also easily damages the hook bolts of the protective plate.After the furnace frame is pressurized,when tightening the bolts,they should be fixed from the center to both sides,and the bolts should be tightened crosswise on the left and right sides to evenly stress the furnace frame and prevent deformation.
