Abstract
A slide rail brick for a steel rolling heating furnace bottom is composed of a slide rail brick body and a reserve expansion gap. The expansion gap is formed in the middle of the slide rail brick body and filled with refractory fibers. The expansion gap is big-end-up, the depth of the expansion gap is three fourths of the width of the brick body, and the upper edge of the slide rail body is in an arc shape. The slide rail brick for the steel rolling heating furnace bottom has the advantages of being simple in structure, convenient to operate and high in work efficiency. The reserve expansion gap can be formed only with the requirement of embedding burning out admixture in the process of manufacture. The expansion gap is adjusted according to using temperature graded distribution of the slide rail brick and is big-end-up. In the process of using, the temperatures and swell capacities of all positions of the slide rail brick are different, so that the swell capacities in different positions are exposed to meet working conditions. The slide rail brick is convenient to install, the service life of a furnace can be improved, and energy conservation and emission reduction are benefited.
Description
Technical field
The utility model relates to a kind of slide brick, is specifically related to a kind of heater for rolling steel furnace bottom slide brick.
Background technology
Slide brick is end to end to be laid on bottom heater for rolling steel, forms the track that steel billet slides.Slide brick will bear high temperature, impurity corrodes and the friction of high temperature billet steel, and environment for use is abominable, and its product quality and installation quality have a strong impact on service life.At present slide brick generally adopts corundum refractory to form through prefabricated high temperature sintering, need to stay between two slide bricks in installation process and establish dilatation joint, and the dilatation joint position is the weak spot of whole track.If dilatation joint stays and establishes too smallly, can cause in process of production slide brick to destroy because of the expanded by heating arch camber, causing stops production changes, and affects the heating furnace operating rate.If dilatation joint stays and establishes excessively, can impact the brickwork joint place in the steel billet sliding process, cause the local damage of slide brick, service life is low.
Therefore, produce a kind of simple in structurely, fitting operation is simple, and the slide brick of long service life has wide market prospects.
Summary of the invention
For the deficiencies in the prior art, it is a kind of simple in structure that the utility model provides, and make efficiency is high, and a kind of heater for rolling steel furnace bottom slide brick of the simple long service life of behaviour is installed.
The technical solution of the utility model is achieved in that a kind of heater for rolling steel furnace bottom slide brick, is comprised of slide brick body and reservation dilatation joint, and dilatation joint is positioned in the middle part of the slide brick body, is filled with refractory fibre in dilatation joint.Described dilatation joint is up big and down small, and the dilatation joint degree of depth is 3/4ths of brick body width.On described slide brick body, the edge is circular-arc.
The utlity model has following good effect: at first, this product structure is simple, and is easy to operate, and high efficiency only needs pre-buried burning lost article can form the reservation dilatation joint when manufacturing.Secondly, dilatation joint stays that establishing distributes according to slide brick serviceability temperature gradient adjusts, and up big and down small, in use, each position temperature of slide brick is different, and the expanded by heating amount is different, has guaranteed that the different parts swell increment all can satisfy working condition requirement.This slide brick is easy for installation, can improve kiln service life, is conducive to energy-saving and emission-reduction.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 for this use novel vertically cut open figure.
The specific embodiment
As shown in Figure 1, 2, a kind of heater for rolling steel furnace bottom slide brick, by slide brick body 1 with reserve dilatation joint 2 and form, dilatation joint 2 is positioned at slide brick body 1 middle part, is filled with refractory fibre 3 in dilatation joint 2.Described dilatation joint 2 is up big and down small, and dilatation joint 2 degree of depth are 3/4ths of brick body 1 width.
On described slide brick body 1, the edge is circular-arc.
This product structure is simple, and is easy to operate, and high efficiency only needs pre-buried burning lost article can form the reservation dilatation joint when manufacturing.In use, each position temperature of slide brick is different, and the expanded by heating amount is different, has guaranteed that the different parts swell increment all can satisfy working condition requirement.This slide brick is easy for installation, can improve kiln service life, is conducive to energy-saving and emission-reduction.
