Description

A kind of environmental protection Chrome-free wear resistance ramming mass
Technical field
The invention belongs to fire resisting material fields, and in particular to a kind of environmental protection Chrome-free wear resistance ramming mass.
Background technology
In existing fire-resistance rammed mass, more or less contains chromium, and it is erosion-resistant to primarily serve raising refractory material Ability, but the compound containing chromium all has certain toxicity, hexavalent chromium Cr6+Toxicity it is maximum, trivalent chromic ion Cr3+ Take second place, bivalent chromium ion Cr2+Toxicity is minimum.It is reported that Cr6+Toxicity compare Cr3+It is almost 100 times big.The compound of chromium is often with molten The form pollution environment of liquid, dust or steam, is detrimental to health, can cause the harm of chronicity, be that a kind of toxicity is extremely strong Strong carcinogen and the substance of serious corrosive medium and heavily contaminated environment.In the oxidations such as chromium oxide and alkali, CaO, SiO2 When object contacts, Cr3+It is transformed into Cr6+Speed accelerate in air, the Cr of formation6+The health of human body is harmful to.Height in material Valency chromium ion is high carcinogen, is polluted the environment.Ramming mass containing chromium has not obviously met environmental requirement, it is necessary to newly be smash with Chrome-free Dnockout replaces ramming mass containing chromium.
Invention content
For overcome the deficiencies in the prior art, the purpose of the present invention is to provide a kind of environmentally friendly Chrome-free wear resistance ramming mass.
In order to achieve the above objectives, the present invention is achieved by the following technical solutions：
A kind of environmental protection Chrome-free wear resistance ramming mass, is mainly composed of the following raw materials by weight：50~60 parts of aggregate, powder 40~ 50 parts, 4~16 parts of bonding agent, 2~6 parts of additive；
The aggregate is made of 15~20 parts of silicon carbide, 10~20 parts of graphite, 40~60 parts of ZTA ceramics；
Wherein：More than 95% purity of carborundum aggregate, is formulated by following grain size distributions：1.18mm >=granularity ＞ 1.00mm, 20~40wt%, 0.85mm >=granularity ＞ 0.72mm, 25~35wt%, 0.30mm >=granularity ＞ 0.19mm, 20~ 30wt%, 0.075mm >=granularity ＞ 0.062mm, 10~20wt%；The carborundum aggregate addition of different-grain diameter particle, to carbon The bulk density influence of SiClx aggregate is very big, so as to influence the density of manufactured ramming mass, above-mentioned varigrained silicon carbide bone Expect weight percent, the carborundum aggregate being mixed into bulk density is made to have reached 2.56gcm-3, improve and ramming mass be made Performance.
More than 98% purity of graphite aggregate, is configured to by following grain size distributions：Granularity ＜ 0.19mm, 20~30wt%； 1mm >=granularity >=0.19mm, 40~45wt%；5mm >=granularity ＞ 1mm, 10~20wt%；8mm >=granularity ＞ 5mm, 10~ 15wt%；10mm >=granularity ＞ 8mm, 5~10wt%；The rational grain size distribution of graphite aggregate, not only increases and ramming mass is made Heat conductivility, thermal conductivity factor can be increased to 12~20w/mk, also increase to other performances of ramming mass.
