Abstract
The utility model relates to a heat isolating protective ring of a furnace roller, particularly a heat isolating protective ring used for a weight-bearing cam furnace roller of a roller hearth soaking furnace or a roller hearth heating furnace. The utility model is composed of a cylindrical ceramic fiber block and a refractory steel fixation buckle, wherein the refractory steel fixation buckle is fixed on the outer side of the cylindrical ceramic fiber block. The utility model has the advantages of convenient and simple technology, low cost, low labor intensity of workers, good work situation, high temperature resistance, enhancement of thermal shock resistance, cracking and spalling damage prevention, light weight, reduction of the furnace roller load in the condition of high temperature, small heat conduction coefficient, low heat loss, good energy-saving effect, long service life, enhancement of production hours and enhancement of labor productivity.
Description
Technical field
The utility model relates to a kind of furnace roller thermal insulation protection ring, especially a kind of load-bearing cam furnace roller thermal insulation protection ring that is used for roller-bottom type soaking pit or heating furnace.
Background technology
Be used for industrial in the market; roller-bottom type soaking pit as the use of industries such as rolling, the ceramic roasting of iron and steel, machined heat treatment; important spare part wherein---load-bearing cam furnace roller; because operating ambient temperature is up to 1100-1400 ℃; and continuous heavy load running in long-term 24 hours; so, must take the thermal insulation protection technology to implement.At present, the furnace roller thermal insulation protection measure is to take to twine methods such as heat-barrier material, pouring fireproof material or sprayed thermal insulant mostly.These methods may cause many bad phenomenon to take place, and the one, the thermel protection device production of load-bearing cam furnace roller safeguards and changes complex process that maintenance is very inconvenient; The 2nd, lost time is many, and labour intensity is big; The 3rd, non-refractory, thermal shock resistance is poor, and cracking peels off damage easily; The 4th, weight is big, has increased the furnace roller load under the condition of high temperature; The 5th, the thermal conductivity factor height, thermal losses is big, even burns out furnace roller, causes life cycle short; The 6th, maintenance work is frequent, produces and reduces man-hour, influences production efficiency.
Summary of the invention
The purpose of this utility model just provides a kind of a kind of furnace roller thermal insulation protection ring that overcomes above-mentioned defective.
The technical solution of the utility model realizes that by following approach it is made up of cylindric ceramic fiber blocks and heat resisting steel tightening buckle, and wherein, the heat resisting steel tightening buckle is fastened on the outside of cylindric ceramic fiber blocks.
It is simple and convenient to the utlity model has technology, and cost is lower; Labor strength is lighter, and work situation is better; High temperature resistance has improved thermal shock resistance, not easy to crackly peels off damage; In light weight, can reduce the furnace roller load under the condition of high temperature; Thermal conductivity factor is little, and thermal losses is low, good energy-conserving effect; Long service life increases and produces man-hour, raises labour productivity.
Description of drawings
Accompanying drawing is a structural representation of the present utility model
Wherein: the cylindric ceramic fiber blocks of 1-, 2-high temperature adhesives layer, the infrared complex liquid emulsified material of 3-layer, 4-heat resisting steel tightening buckle
The specific embodiment
Describe the specific embodiment of the present utility model below in detail.
The utility model is made up of cylindric ceramic fiber blocks 1 and heat resisting steel tightening buckle 4, wherein, heat resisting steel tightening buckle 4 is fastened on the outside of cylindric ceramic fiber blocks 1, but 1 one-shot forming of cylindric ceramic fiber blocks can also be combined by two above garden arcuations or strip and block ceramic fiber blocks.
Inner surface at cylindric ceramic fiber blocks 1 scribbles furnace roller special-purpose high temperature bonding agent layer 2.
Outer surface at cylindric ceramic fiber blocks 1 also scribbles high-temperature infrared complex liquid emulsified material layer 3, and the thickness of infrared complex liquid emulsified material layer 3 is in the time of 1100-1250 ℃, and thickness is 1-2mm, in the time of 1250-1400 ℃, and thickness 2-3mm, at 1400-1600 ℃, thickness 3-4mm.The high-temperature infrared complex liquid emulsified material model of spraying should be selected and the corresponding product of operating temperature, to promote protection and energy-saving effect.
The material of heat resisting steel tightening buckle 4 should be considered the height of operating temperature, generally should select the material higher than operating temperature, the heat resisting steel tightening buckle can adopt planar structure or network, and its fastening means can adopt modes such as button, hook, riveting, weldering or bolt, should decide on the inner operating situation.
Ceramic fiber blocks can be that materials such as high alumina type, zirconium aluminium type, zirconium chromium type and mullite are made, and the form of these materials can be blanket, plate, piece, profiled piece.
