Fire-resistant furnace door with integral fiber process structure

Abstract

The invention discloses a fire-resistant furnace door with an integral fiber process structure, and relates to the field of fire-resistant equipment. The device comprises a furnace door protection plate and an anchoring net structure, an integral fiber module is assembled in the furnace door protection plate and the anchoring net structure, the integral fiber module comprises folding piece units which are sequentially and horizontally arranged perpendicular to a furnace door, and the anchoring net structure comprises transverse anchoring rod units and vertical anchoring rod units which are arranged in a crossed mode; thermal expansion joints are arranged on the anchoring rod units at intervals; the problems of deadweight sinking deformation failure, anchoring piece deformation and thermal oxidation erosion failure of the fiber module are solved, in addition, the whole fiber module is formed by compressing the folding piece units which are sequentially and horizontally arranged perpendicular to the furnace door, and the situation that large gaps exist on the surface of the fiber module, consequently, uneven heating is caused, and the fire resistance and heat preservation performance of the furnace door are affected is avoided; when the anchoring net structure is heated to expand and deform, the thermal expansion joints contract to balance the anchoring net structure, and the repeated deformation degree of the anchoring net and the whole fiber module is reduced.

Description

technical field [0001] The present application relates to the field of refractory equipment, in particular to a refractory furnace door with an integral fiber process structure. Background technique [0002] The sealing problem of the furnace door and furnace mouth of industrial furnaces, especially high-temperature heating furnaces, has always been a problem that plagues the industry. The refractory material on the refractory face of the furnace door will produce various failure modes during use, including the failure of high temperature material denaturation, the failure of high temperature flue gas erosion and erosion, the failure of repeated expansion and contraction due to thermal vibration, the failure of self-weight sinking deformation, and the deformation of anchors. And thermal oxidation erosion failure, bumping and wear failure, etc., the integrity of the furnace door functionality is particularly important for industrial furnaces. [0003] The traditional furnace...

AI Technical Summary

Problems solved by technology

[0003] The traditional furnace door is made of lightweight refractory fiber material, which has great advantages in sealing the furnace door and saving energy and reducing emissions of the heating furnace. However, the overall fiber process structure refractory furnace door adopts a multi-fiber module structure. Irregular maintenance, frequent maintenance and high cost, and the gap between fiber modules is usually a key node that is prone to failure, and is the main factor affecting the overall life of the overall furnace door. Therefore, a refractory furnace door with a better structure is developed imperative
