Description
Technical field
The present invention relates to a kind of preparation method of industrial furnace.
Technical background
In common industrial production, one hot-working, heat treatment step are arranged, be many industrial products manufacture processes must process, the key of this procedure is an equipment, i.e. industrial furnace.The quality of industrial furnace quality directly influences the quality of product, and the quality height of furnace wall and burner hearth in the stove is one of leading indicator of dividing the industrial furnace quality.For a long time, the groundwork of industrial furnace partly is a body of heater, and the various refractory brick of the general employing of the furnace wall of body of heater are as common brick, schamotte brick, corundum brick, silica brick, magnesia brick, high-alumina brick, light fire brick etc.; Perhaps use various types of castable refractories, light weight castable refractory, fire-resistance rammed mass and plastic refractory, these refractory materials all are classical furnace building materials, generally use in making various industrial furnaces, as steel rolling soaking pit, heating furnace, annealing furnace, annular furnace, building materials tunnel cave, down-draft kiln, chemical petroleum stove, machined heat-treatment furnace etc.More than various materials different handling characteristics and advantage are arranged, but also come with some shortcomings, as in use, the stove brickwork joint is easily loosening, easy to crack, water the easy crackle of material feeding, easily peel off, and the thermal conductivity factor height, the suction amount of stored heat is many, and heat-insulating property is poor, often need maintaining, cause increase nonproductive man-hour, greatly influenced manufacturing schedule, especially construction is loaded down with trivial details in industrial furnace, and labour intensity is big, problems such as the process-cycle is long, and cost is high are perplexing the stove industry always.
Summary of the invention
The present invention just provides a kind of preparation method that overcomes the industrial furnace of above-mentioned defective.
Technical scheme of the present invention, a kind of preparation method of industrial furnace is characterized in that: the technological process of the preparation method of described industrial furnace is: spray fiber adhesive aid layer, sprayed fire-resistant fiber adhesive layer, stickup refractory fiber block layer, spraying high-temperature infrared material adhesive aid layer and spraying high-temperature infrared complex liquid emulsified material layer on the Industrial Stoves body of heater inner surface of making; Concrete steps are as follows: A, the body of heater inner surface of industrial furnace is cleaned, make its inner surface not have greasy dirt and floating ash, spray fiber adhesive aid layer on inner surface then, its thickness is 0.1～0.3mm sprayed fire-resistant fiber binding agent again, the thickness of its refractory fibre adhesive layer is 2～6mm; B, paste refractory fiber block being sprayed with on the body of heater surface of refractory fibre adhesive layer, and form the refractory fiber block layer, its fiber block thickness is 18～100mm; C, on the refractory fiber block layer spraying one deck high-temperature infrared material adhesive aid layer, its high-temperature infrared material adhesive aid layer thickness is 0.2～0.5mm; D, treat that the air dry of high-temperature infrared material adhesive aid layer is after 0.5～1 hour, spray high-temperature infrared complex liquid emulsified material again, treat that its high-temperature infrared complex liquid emulsified material laminar surface condenses afterwards, its high-temperature infrared material thickness is to set by the stove operating temperature range: the stove operating temperature is 800～1600 ℃, the thickness of its high-temperature infrared dope layer is 0.8～3mm
The refractory fibre adhesive layer of above-mentioned spraying can be high temperature adhesives or high temperature adhesive or high-temperature refractory fiber binding agent; The refractory fiber block layer of pasting can be refractory ceramic fibre piece or adiabatic with aluminium silicate wool piece or polycrystalline mullite fibre piece; The high-temperature infrared complex liquid emulsified material layer of spraying can be high-temperature infrared coating or high temp, infrared radiation coating or high-temperature infrared energy-conserving paint.Spraying method of the present invention can both can adopt spraying according to execution conditions, also can adopt the brushing mode to carry out.
The industrial furnace operating temperature that the present invention makes is 800-1600 ℃, has high temperature resistance, and thermal conductivity factor is low, and thermal losses is little, and environmental thermal pollution is little, sufficient combustion, and programming rate is fast, and energy consumption is low; Has good thermal shock resistance, anti-oxidant and chemical resistance of concrete; But also have not easy to crack, incrust, from heavy and light, long service life, maintenance man-hours is few, labor productivity height, the characteristics that labor strength is low; Simultaneously, do not change original design, quick construction is convenient.
