Abstract
The invention relates to a light-weight fireproof castable for furnaces. The castable is prepared from the following raw materials in percentage by weight: 20-40% of volcanic rock, 15-35% of shale ceramsite, 15-35% of perlite, 5-15% of pure calcium aluminate cement, 0.1-1.5% of white clay and 1-3% of a bonding agent. The light-weight fireproof castable for the furnaces, disclosed by the invention, has the beneficial effects that volcanic rockwaste resources are mainly used as raw materials for making the light-weight fireproof castable, and besides, after the furnaces are disassembled, the light-weight fireproof castable can be recovered for reuse, and environmental protection is facilitated; the light-weight fireproof casting material has the advantages of being light in weight, good in thermal insulation performance, good in sound insulation performance, high in strength, convenient to construct, long in service life and the like, concurrently has the effects of load bearing, heat preservation and shock resistance, and can be widely used for working lining or permanent lining of middle and high temperature furnaces in electric power, chemical industry, metallurgy and the like.
Description
Technical field
The invention belongs to a kind of novel brickwork, build the middle working lining of high temperature kiln or the Lowweight Refractory Castablies of permanent liner such as kiln.
Background technology
Promote and expand the developing direction that use amorphous refractory is brickwork technology, the plastic refractory, refractory castable etc. of widespread use are in recent years main amorphous refractory, compared with refractory brick, save the operations such as molding and firing processes, save energy consumption.Use amorphous refractory brickwork, the overall performance of stove is good, tight, solid, the life-span is long, thus improves the operating rate of stove, therefore can improve the technico-economical comparison of stove comprehensively.There is a kind of mould material to take luminite cement as bonding agent, because cement-hydrate is 800 DEG C ~ 1000 DEG C dehydrations, mould material medium temperature intensity is reduced, again because Ca0 content in luminite cement is on the high side, form calcium under high temperature and to grow up stone, can only use below 1300 DEG C.Another kind of mould material adopts low calcium pure calcium aluminate cement to be bonding agent, and cement consumption reduces half, and mould material use temperature has brought up to 1450 DEG C ~ 1600 DEG C.But soundproof effect is poor, shock resistance is strong, building body poor stability.
Summary of the invention
Object of the present invention utilizes middle-low grade refractory raw material, produces to have high strength, be well incubated, the stove refractory castable that soundproof effect is good He free from environmental pollution.
Realizing above-mentioned purpose technical scheme is: this mould material is formulated according to weight part by following raw material: the volcanics of 20 ~ 40%, the haydites of book structure of 15 ~ 35%, 15 ~ 35% perlite, the pure calcium aluminate cement of 5 ~ 15%, the white clay of 0.1 ~ 1.5% and 1 ~ 3% bonding agent formed by their Homogeneous phase mixing.
Used have the particle diameter of raw material volcanics, haydites of book structure to be all no more than 1 millimeter.
The beneficial effect of the invention is: environment friendly light refractory casting material mainly utilizes volcanic rock waste resource for raw material; and all right recycling after tearing stove open; be conducive to environment protection; there is the advantages such as lightweight, heat insulation, sound insulation, high-strength, easy construction, long service life; have load-bearing and insulation and antihunt action concurrently, working lining or the permanent liner of high temperature kiln in electric power, chemical industry and Zhi Jin etc. can be widely used in.
Embodiment
First raw material volcanics, haydites of book structure, perlite are pulverized before preparing this mould material, make its particle diameter all be no more than l millimeter, volcanics also can use waste material.
The raw material volcanics 35kg of EXAMPLE l, pulverizing of learning from else's experience, haydites of book structure 27kg, perlite 22kg, pure calcium aluminate cement 13kg, white clay 1.2kg and bonding agent 1.8kg, above-mentioned raw materials Homogeneous phase mixing, loads in bag stand-by.
The raw material volcanics 33kg of example 2, pulverizing of learning from else's experience, haydites of book structure 29kg, perlite 21kg,
Pure calcium aluminate cement 14kg, white clay 0.8kg and bonding agent 2.2kg, above-mentioned raw materials Homogeneous phase mixing, loads in bag stand-by.
The raw material volcanics 38kg of example 3, pulverizing of learning from else's experience, haydites of book structure 25kg, perlite 29kg, pure calcium aluminate cement 7kg, white clay 0.6kg and bonding agent 2.4kg, above-mentioned raw materials Homogeneous phase mixing, loads in bag stand-by.
Claims (2)
1. a stove Lowweight Refractory Castable, is characterized in that: this mould material is formulated according to weight part by following raw material: the volcanics of 20 ~ 40%, the haydites of book structure of 15 ~ 35%, 15 ~ 35% perlite, the pure calcium aluminate cement of 5 ~ 15%, the white clay of 0.1 ~ 1.5% and 1 ~ 3% bonding agent formed by their Homogeneous phase mixing.
2. a kind of stove Lowweight Refractory Castable according to right 1, is characterized in that: used have the particle diameter of raw material volcanics, haydites of book structure to be all no more than 1 millimeter.
