Problems solved by technology

[0002] At present, the continuous annealing furnaces for medium and low-grade non-oriented cold-rolled silicon steel basically use all-brick refractory masonry structures (such as figure 1 As shown), the disadvantage is that the furnace body has a large thermal inertia, the furnace temperature control response is slow, the shell temperature is high, the furnace space is large, and the energy consumption is high

Embodiment Construction

[0014] Such as figure 2 , image 3 As shown, the refractory masonry composite structure of the heating section of the continuous annealing furnace for cold-rolled electrical steel is composed of the furnace roof, the left furnace wall, the right furnace wall and the furnace bottom. The furnace roof, the left furnace wall, the right furnace wall and the The hearth is surrounded by the bottom of the furnace, and the furnace roof of the heating section is made of fiber modules 1; The hot brick 3 is built by masonry, and the fiberboard 2 is positioned at the outside of the heat-resistant brick 3 [the side close to the furnace is the inner side, the cold surface of the furnace shell adopts fiberboard, and the hot surface of the furnace adopts heat-insulating bricks]. The furnace wall includes a left furnace wall and a right furnace wall, both of which are made of fiberboard 2 and heat-resistant bricks 3 .

[0015] The furnace roof of the heating section is a flat roof structure....

Abstract

The invention relates to a refractory material built combined structure for the heating section of a cold rolled electric steel continuous annealing furnace, which is characterized in that: the furnace top of the heating section is built by using fiber modules; and the furnace wall and furnace bottom of the heating section are both built by using fiber plates and heat-resistance bricks, and the fiber plates are positioned on the outer sides of the heat-resistance bricks. The combined structure has a characteristic of energy conservation.

Description

technical field [0001] The invention relates to a refractory masonry composite structure in the heating section of a continuous annealing furnace for cold-rolled electrical steel. Background technique [0002] At present, the continuous annealing furnaces for medium and low-grade non-oriented cold-rolled silicon steel basically use all-brick refractory masonry structures (such as figure 1 As shown), the disadvantages are that the furnace body is thermally inert, the furnace temperature control response is slow, the shell temperature is high, the furnace space is large, and the energy consumption is high. Contents of the invention [0003] The object of the present invention is to provide a refractory masonry composite structure in the heating section of the continuous annealing furnace for cold-rolled electrical steel, which has the characteristics of energy saving. [0004] In order to achieve the above object, the technical solution adopted by the present invention is: ...
