Description
Technical field
The utility model belongs to industrial furnace field, more particularly to heating furnace side wall lash-up recovering device.
Background technology
It is typically employed in stove skin steel plate in the side wall of industrial furnace field, particularly heater for rolling steel and hangs oneself to hang and puts anchoring
After part, poured and formed using castable refractory segmentation ramming.Heater for rolling steel especially large-scale walking beam type heating furnace is due to stove
Thorax is highly larger, and furnace side would generally be divided into top, the cast of bottom furnace wall piecemeal.Side wall anchoring piece is usually mechanism anchored brick, its
Most of stress is born by anchored brick.Because generally long-time, big load is worked continuously when heater for rolling steel, which is run, to be produced, and
Anchored brick is easy to aging under vibration, hot conditions for a long time, deforms, fracture, causes side wall introversion, serious threat production fortune sometimes
Row safety.Because heater for rolling steel is the key equipment of steel rolling production-line, its blowing out node and time have it is strict planned, and
Due to equipment high temperature itself, the characteristic of high pressure, short-term blowing out is difficult to carry out large range of maintenance to change.
Because furnace wall is removed, to build workload by laying bricks or stones larger；Anchored brick is polymorphic structure, and fabrication cycle is longer；Furnace outage time mistake
Length can have a strong impact on the production run of whole piece rolling line, cause larger economic loss.If found in the inspection of short-term blowing out
The problems such as side wall introversion, it is typically only capable to do some emergency trouble shooting measures, until the scheduled major overhaul time does larger maintenance, applied again
Work.
