Operation of loading of kiln of kiln pouring blaze should make sure bricky battlements is smooth, firm, straight not only, and make goods be heated even, in order to give firing offer wanted precondition.
(1) should clear before loading of kiln kiln bottom, make kiln ground level, aperture suction internal heat is not jammed (outside dividing a for temperature adjustment aperture suction internal heat) , raise flue and advocate flue is expedite.
(2) planish by operating rules ground bake or dry by the heat of a fire, ground bake or dry by the heat of a fire spans aperture suction internal heat, undertake on ground bake or dry by the heat of a fire the brick works piling up. Aperture suction internal heat has how many, ground bake or dry by the heat of a fire hits how many. This platoon kang calls a line on fireproof material loading of kiln or approve. To make kang or bricky battlements smooth, often use kiln sand. Kiln sand should pledge according to goods sex and use not congenial kiln sand, the kiln sand that uses normally has: Argillaceous grog is qualitative, tall aluminous grog is qualitative, chromic magnesian silicon is qualitative, qualitative sand waiting for kiln and rice husk.
(3) the brick is listed (or batch) width can be decided according to the size of kiln and product measure, it is 880〜960mm commonly. The passageway is 120〜170mm between bricky row. A few span can adopt upper limit among round kiln pouring blaze, the span that stands by wicket can use floor level. Its purpose is with what differ resistance adjusts the air current inside kiln, reach the temperature inside kiln even.
(4) the height of kiln battlements is in make sure battlements of product quality, brick is mixed firm below the condition that puts on kiln safety, as far as possible some taller. Height is 0.9〜1.2m commonly, wear with kiln builds a heatable brick bed with the brick or be being built, continue to load a brick again. People build wear or build kang to call " pace kang " . Divide up from the bottom for one pace kang, 2 paces kang... . Upside is called " pointed " . The property of the height that particular branch pace wants to see kiln, goods, raw material reachs craft condition and decide. The Gaokeduo that be like kiln divides a pace, pit is small can divide a pace less; Bricky battlements is tall can divide a pace less, bricky pile is small but much pace. Bricky battlements is surely really highly decide according to product quality, appearance, dimension. If silica brick goods can be installed all the time from kiln bottom,support to kiln. But wear to build outfit is complex model goods or make whole batch and firm safety, bake or dry by the heat of a fire is drawn with ripe brick among. And argillaceous brick, tall aluminous brick, magnesian simple product, light qualitative brick is installed not easily exorbitantly, it is 700〜900mm commonly. 2, tall aluminous brick can hold third class some taller.
(5) adobe acts a way: Can divide install to establish outfit, paper-cover and side. General silica brick is used stand outfit; Argillaceous brick, tall aluminous brick, magnesia brick uses side outfit; Tall aluminous brick and magnesia brick also but paper-cover. Specific outfit law can be decided according to figure of respective craft condition and product. Should stay between the brick when piling up a brick and brick the hand is seamed (the goods with complex to appearance not easy durable outfit is crowded prison) , the upside hand of kiln seams a little bit small, somes bottom is big, the hand is seamed make an appointment with 5〜12mm. This is to improve heat to exchange a condition, make temperature even, it is more important to package the product that burn to those needs especially. Join combustible to make the adiabatic product that inserts a future life produces to using, make sure air current is expedite when loading of kiln, and as far as possible reduce the interface between brick and brick to accumulate.
(6) special and refractory products can use the method such as hoisting, thick packet, filling or coating to undertake loading of kiln. General products is in the loading of kiln of circle kiln, the method that can use circumjacent couplet to approve raises the temperature of quantity of loading of kiln and even periphery and kiln center, couplet approves width to be 1.5m left and right sides commonly. The products with large goods and sophisticated appearance often holds the bottom that a few batches are in among kiln " one pace kang " and " 2 paces kang " , because this place temperature is fluctuant not big, and slightly low, put on kiln to go to the lavatory.
(7) the kiln to headroom, to ensure every are approved firm, can use batch with batch between the method that takes post of exceeding lofty or great.
Standard type or the bricky outfit of brief monotype often are used to be in when loading of kiln bricky battlements is outside (common calls wrapping the brick) , interior holds large goods and figure sophisticated products, especially very important to the production of silica brick.
String together to prevent broken bits corrode and internal heat, stand by fire box place to want to be blocked with the bag that abandon a brick, bricky battlements brick of the kiln on coping lid.
(8) density of loading of kiln (show effective unit volume can hold goods weight inside kiln, t/m3) . Think commonly: Argillaceous brick 0.65〜1.0t/m3, 0.7〜0.9t/m3 of magnesian simple product, silica brick 0.75〜1.0t/m3, 0.6〜0.8t/m3 of tall aluminous brick.
(9) the central line in two wicket, place of 0.5〜0.7m of the bottom that be apart from kiln and 1.6〜1.7m place stay have measure place blandly measure Wen Zhui fire to. Kiln center measures lukewarm dot to be in up and down kiln is mid, want tower above two wicket place measures temperature to nod 110〜150mm, the both ends inside kiln measures Wen Zhui to be put in be apart from wicket 2〜2.2m to be in. Measure configuration of lukewarm awl number:
