Abstract
The invention discloses a refractory material for a coking furnace, and relates to the technical field of refractory materials. The refractory material for the coking furnace is prepared from the following raw materials in parts by weight: 0.2-2 parts of zirconium-titanium alloy, 35-60 parts of aluminum oxide, 2-10 parts of silicon carbide fiber, 0.05-0.2 part of lanthanum oxide, and 3-8 parts of borax. The refractory material for the coking furnace is prepared from the zirconium-titanium alloy, aluminum oxide, the silicon carbide fiber, lanthanum oxide, and the borax, and is good in high resistance, oxidation resistance, slag penetration resistance, thermal shock resistance and stability. The defect that the traditional product is short in service life, and unstable in performance is solved; compared with the traditional refractory material for the coking furnace, the service life of the product can be prolonged for 1-2 years.
Description
Technical field
The present invention relates to technical field of refractory materials, especially a kind of coke oven refractory material.
Background technology
A kind of stove being generally built into by refractory brick and refractory block of coke oven, for making coal carbonization to produce the kiln of coke, is the main Thermal Equipment of coking.Modern coke oven refers to production metallurgy Jiao as main purpose, can reclaim the horizontal-chamber type coke oven of coking chemistry product, is made up of body of heater and auxiliary device.Coking furnace shaft is by parts such as furnace roof, combustor and carbonization chamber, chute district, regenerator, and is connected with chimney by flue.
Refractory material refers to that refractoriness is not less than a class Inorganic Non-metallic Materials of 1500 DEG C, and refractoriness refers to that refractory material bullet sample, in the case of not having loading, is resisted high temperature action and do not softened molten Celsius temperature.Application to refractory is in the every field of the national economy such as iron and steel, non-ferrous metal, glass, cement, pottery, petrochemical industry, machinery, boiler, light industry, electric power, military project, it is to ensure that above-mentioned industry production run and technology develop requisite stock, hot industry production development plays irreplaceable important function.
Existing coke oven uses the cycle all less than 5 years, and the life-span is shorter, and it main reason is that use cycle of refractory material of its inwall is shorter, and less stable, therefore, seek a kind of novel coke oven refractory material, have great meaning for extending the service life of coke oven.
Summary of the invention
It is an object of the invention to provide a kind of coke oven refractory material, this coke oven refractory material can solve existing coke oven refractory material and use cycle short problem.
In order to solve the problems referred to above, the technical solution used in the present invention is:
This coke oven refractory material, is prepared from by the raw material of following parts by weight: zirtan 0.2 part～2 parts, aluminium oxide 35 parts～60 parts, silicon carbide fibre 2 parts～10 parts, lanthana 0.05 part～0.2 part, Borax 3 parts～8 parts.
In technique scheme, more specifically scheme it may also is that in zirtan zirconium content be 10% ~ 40%.
Further, a diameter of 0.05 micron～0.5 micron of carborundum, a length of 50 microns～100 microns.
Further, the parts by weight of raw material are: zirtan 0.2 part, aluminium oxide 50 parts, silicon carbide fibre 2 parts, lanthana 0.1 part, Borax 3 parts.
Further, the parts by weight of raw material are: zirtan 1 part, aluminium oxide 60 parts, silicon carbide fibre 6 parts, lanthana 0.2 part, Borax 5 parts.
Further, the parts by weight of raw material are: zirtan 2 parts, aluminium oxide 35 parts, silicon carbide fibre 10 parts, lanthana 0.05 part, Borax 8 parts.
Owing to have employed technique scheme, the present invention compared with prior art has the advantages that
Coke oven refractory material of the present invention, it is prepared from by zirtan, aluminium oxide, silicon carbide fibre, lanthana and Borax, its heat-resisting quantity, non-oxidizability, slag-resistant permeability, thermal shock resistance and have good stability, product of the present invention overcomes that traditional product service life is short, the shortcoming of unstable properties, compared with traditional coke oven refractory material, the service life of product of the present invention can extend 1-2.
