Description

A steel structure component for the installation of all-fiber furnace roof materials for heating furnaces

technical field

The present application relates to the field of heating furnaces, in particular, to a steel structure component used for installation of all-fiber roof materials of heating furnaces.

Background technique

The steel rolling heating furnace needs to install furnace roof refractories to withstand the high temperature of the furnace and reduce heat loss. The full fiber refractory roof can effectively reduce heat loss and is increasingly introduced into the steel rolling heating furnace. At present, steel structure components for fixing high-temperature-resistant fiber module materials in all-fiber refractory furnaces mostly adopt integral flat steel plate plus profile steel reinforcement structure or use grid plate splicing components to hang on the furnace roof hanging beam.

When the steel structure components installed on the furnace top refractory adopt the overall flat steel plate plus section steel reinforcement structure, although it is more convenient to install and fix the heat-resistant steel screw rod, the flat steel plate on the furnace top will produce irregular thermal expansion deformation and large Concentrated deformation will cause greater destructive tearing on the high-temperature resistant fiber module and heat-insulating fiber lining board, tearing cracks and redness or even fire. At the same time, due to the overall flat steel structure covering It is very inconvenient to maintain and repair the fire parts.

Although the steel structure components installed on the furnace top refractory materials adopt the grid plate splicing structure, the problem of thermal expansion and deformation of the furnace roof steel components can be eliminated to a certain extent, but the heat-resistant steel screws installed with high-temperature-resistant fiber modules are very inconvenient to locate and fix. It is also difficult to maintain and deal with when the roof is red or flaming. More importantly, the grid panel splicing components cannot protect the heat-insulating fiber lining and high-temperature-resistant fiber modules from external impact damage due to the existence of pores.
