Abstract
The utility model relates to a furnace-protecting carbon brick, the carbon brick surface is equipped with the coating of carbon brick parcel, and the coating thickness scope is 0.1 ~ 0.3mm, and the metal powder composite coating of coating for containing titanium, the coating adopt hot spraying technique spraying. Compared with the prior art, the utility model has the advantages that: the furnace-protecting carbon brick adopts metal powder containing titanium, is sprayed on the surface of the carbon brick by utilizing a thermal spraying technology, and a layer of metal powder composite coating containing titanium is naturally attached to the inner wall of a furnace hearth built by the carbon brick, so that the blast furnace hearth has the performances of high temperature resistance, erosion resistance and circulation and erosion resistance, and the furnace-protecting carbon brick has a simple structure and strong practicability, and effectively improves the service life of the blast furnace.
Description
Technical field
The utility model relates to technical field of refractory materials, particularly a kind of furnace retaining carbon brick.
Background technology
In ironmaking is produced; The cupola well of iron-smelting blast furnace is built by laying bricks or stones by refractory brick and is formed; Refractory brick is main with carbon brick mainly, and in the furnace life of the quality of carbon brick decision generation blast furnace, common blast-furnace production campaign present stage is generally about 15 years; Some blast furnace do not reach at all generation furnace life with regard to overhaul from newly building by laying bricks or stones, What is more causes serious accident generation consequences such as burn-through of furnace hearth very serious.And mainly be secular furnace retaining and interim fettling for the maintenance of cupola well; The method of furnace retaining and fettling mainly is in furnace charge, to add the titanium composition; Perhaps lining is made in spraying, and purpose is interior high temperature resistant, the erosion resistant lining form of one deck that forms of cupola well that makes blast furnace, and then the furnace life of improving blast furnace; Practice thrift equipment funds, but common carbon brick does not but reach such performance now.
Therefore, the cupola well of blast furnace needs a kind of carbon brick with high temperature resistant, anti-erosion, anti-circulation performance of flushing.
Summary of the invention
The purpose of the utility model provides a kind of furnace retaining carbon brick, and this carbon brick has high temperature resistant, anti-erosion, anti-circulation performance of flushing, and simple in structure, practical.
For realizing above-mentioned purpose, the utility model is realized through following technical scheme:
A kind of furnace retaining carbon brick, said carbon brick surface are provided with the coating with the carbon brick parcel.
Described coat-thickness scope is 0.1～0.3mm.
Described coating is the metal-powder compound coating that contains titanium.
Described coating adopts the hot-spraying techniques spraying.
Compared with prior art; The utility model has the advantages that: this furnace retaining carbon brick adopts the metal-powder that contains titanium; Utilize hot-spraying techniques to be sprayed on the carbon brick surface, the hearth wall that uses this carbon brick to build by laying bricks or stones adheres to the metal-powder compound coating that one deck contains titanium naturally, and then makes blast furnace hearth have high temperature resistant, anti-erosion, anti-circulation performance of flushing; And simple in structure, practical, effectively raise the blast-furnace production campaign.
Description of drawings
Fig. 1 is the schematic cross-section of the utility model.
Among the figure: 1-carbon brick 2-coating
Embodiment
Describe in further detail below in conjunction with the embodiment of accompanying drawing the utility model.
See Fig. 1, a kind of furnace retaining carbon brick, carbon brick 1 surface is provided with the coating 2 with carbon brick 1 parcel, and coating 2 thickness ranges are 0.1～0.3mm, and coating 2 is for containing the metal-powder compound coating of titanium, and coating 2 adopts hot-spraying techniques to be sprayed on carbon brick 1 surface.
This utility model adopts the metal-powder that contains titanium to process coating 2; Utilize hot-spraying techniques that coating 2 is sprayed on carbon brick 1 surface; When using this utility model to build cupola well by laying bricks or stones, make the hearth wall surface adhere to the metal-powder compound coating 2 that one deck contains titanium naturally, and then make blast furnace hearth have high temperature resistant, anti-erosion, anti-circulation performance of flushing; And simple in structure, practical, effectively raise the blast-furnace production campaign.
