Abstract
The invention discloses a prefabricated refractory wallboard used for a graphitized furnace. The prefabricated refractory wallboard comprises a wallboard body provided with a steel reinforcement framework structure, wherein the wallboard body is provided with a lifting ring and a plurality of air vents run through horizontally. The manufacture method for the prefabricated refractory wallboard comprises the steps of 1) taking flint clay as the main material and the aluminate cement, clay fine powder, a-Al203 micro powder, SiO2 micro powder, explosion-proof fibers and the like as the auxiliary material; 2) manufacturing the steel reinforcement framework; 3) conducting proportioning on the flint clay according to the three-level grading, then adding the aluminate cement, the a-Al203 micro powder, the SiO2 micro powder, the clay fine powder, the explosion-proof fiber and other auxiliary materials, and then adding water and stirring after premixing, finally adding the materials into a mould for vibration moulding; and 4) routine maintenance. The prefabricated refractory wallboard disclosed by the invention is simple in structure, convenient in manufacturing, low in labour intensity of the worker and short in maintenance cycle, saves the burning process, improves the capacity of the graphitized furnace, and has the characteristics of energy conservation, environmental friendliness and high efficiency, and the wallboard can be ensured for 50 times.
Description
Technical field
The present invention relates to fire-resistant structural member for building that a kind of graphitizing furnace uses and preparation method thereof.
Background technology
Graphitizing furnace is the key equipment of carbon element factory, and body of heater in use will bear long hot operation and lower the temperature frequently and temperature-rise period, for prolonging its work-ing life, requires used refractory materials to have good thermal shock resistance.At present, the furnace wall part Commonly Used Size of China's graphitizing furnace body of heater is that 230 * 114 * 65 fire-resistant standard brick is built by laying bricks or stones, and each stove burns need be removed furnace wall when finishing blowing out and clear up maintenance, next stove need be built furnace wall by laying bricks or stones again again, labor strength is big, and production efficiency is low, the production cost height.
Summary of the invention
The problem to be solved in the present invention is to provide a kind of graphitizing furnace with prefabricated fire-resistant wallboard, and it is simple in structure, and assembly operation is convenient, economization the fragment of brick of old-fashioned furnace wall build and remove operation by laying bricks or stones, alleviated labor strength, improved the production efficiency of graphitizing furnace.
The present invention adopts following technical scheme: comprise the wallboard body that is provided with the Framework Of Steel Reinforcement structure, described wallboard body is provided with the ventilating pit of hoisting ring and the perforation of several levels.
Its principle is: change the former formula furnace wall of building by laying bricks or stones into prefabricated refractory wall plate structure of the present invention, the wallboard body is provided with hoisting ring, utilizes hoisting ring can carry out integral hoisting; The ventilating pit that the level that is shaped in advance on the wallboard body connects replaces the former ventilating pit that the formula furnace wall is built by laying bricks or stones of building by laying bricks or stones; The Framework Of Steel Reinforcement structure can strengthen the bulk strength of wallboard body, and purpose is to ensure the repeatedly strength demand of lifting.Its is short site operation duration, reduced the labour intensity that the workman safeguards graphitizing furnace, shortened maintenance cycle, improved the production capacity of graphitizing furnace.
Another problem that the present invention will solve is to provide the making method of a kind of graphitizing furnace with prefabricated fire-resistant wallboard.
A kind of graphitizing furnace is characterized in that comprising the steps: with the making method of prefabricated fire-resistant wallboard
1) raw material is prepared: a, aggregate preparation: with flint clay fragmentation, screening, and dry for standby after the size classification; B, other raw material: aluminate cement, well as clay fines, a-Al
2O
3Micro mist, SiO
2Micro mist, explosion-proof fiber;
2) make Framework Of Steel Reinforcement, at rebar surface brushing pitch;
3) with flint clay 28-35%, the flint clay 8-10% of 5-10mm granularity, flint clay 25-30%, the flint clay fine powder 8-10% of 10-16mm granularity, aluminate cement 12-15%, the a-Al of above-mentioned raw materials by weight the 0-5mm granularity
2O
3Micro mist 3-5%, SiO
2Micro mist 3-5%, well as clay fines 3-5%, the pre-mixing of explosion-proof fiber 2-3% ratio adds behind the water and stirs with stirrer, will stir the mould internal vibration moulding that the material adding is built-in with Framework Of Steel Reinforcement then;
4) conventional maintenance.
Prefabricated fire-resistant wallboard of the present invention is cooked major ingredient with flint clay, and aluminate cement is made wedding agent, a-Al
2O
3Micro mist increases shrinkage-compensating effect, SiO
2Micro mist can increase flexible property and the dispersiveness of compound, reduce water consumption, reduce the void content of prefabricated component, improve compressive strength, well as clay fines is made agglutinant, can prevent the internal organizational structure generation acute variation of prefabricated fire-resistant wallboard when the working temperature sintering, can improve its medium temperature intensity, the flint clay aggregate adopts three grades of gratings, bulk strength height.
The present invention is simple in structure, easily manufactured, economization 1400 ℃ calcination process of traditional refractory brick, can lift to the body of heater of graphitizing furnace after finishing maintenance, in use the working temperature by graphitizing furnace can reduce the labour intensity that the workman safeguards with its sintering, shortened maintenance cycle, improved the production capacity of graphitizing furnace, can reach 50 stoves work-ing life, has the characteristics of energy-saving and environmental protection, synergy.
