【正文】 產(chǎn)品質(zhì)量和產(chǎn)量都會很低。拋光磚產(chǎn)品的形狀，吸水率，抗壓強度及存放滯變情況都受到窯爐燒成制度合理程度的影響。燒成在陶瓷生產(chǎn)中是非常重要的一道工序。產(chǎn)品單位能耗一般在2000～3500 KJ/Kg ，而傳統(tǒng)隧道窯則高達5500～9000 KJ/Kg 。另一種是連續(xù)式窯爐,比如輥道窯。因此正確選擇燒成窯爐是獲得性能良好制品的關(guān)鍵。 every two holes have a pair of temperature, temperature control, respectively, stretching from the furnace top and side, the side Temperature with the wrong hole layout is conducive to relatively close to full access to the internal furnace temperature data. In order to facilitate the work of masonry, masonry in the design, I will take into account the height of cut as much as possible the direction of brick, and the calculation has a single thickness of brick and mud into the design. This design will be out of the hot air part of the slow cooling for bustion, enhanced bustion and preheating, and the remaining waste heat and preheat with hot smoke smoking section out of water for the dry and can be a good energy saving and emission reduction. I designed the roller kiln, my kiln tends to light and small, design may be relatively conservative, but they find useful. All kiln with good air tight layout, cut off from the kiln internal and external environment as much as possible, promote cleaner production, optimize the working environment.

Using natural gas as fuel, highspeed pulse burner burner, plus a brick burner casing instead of the way, can effectively improve the bustion quality．Accident relatively dense arrangement of holes, relatively staggered layout．Exhaust port and pump hot air up and down in the roll were set, and in these sections before and after the retaining wall and the baffle has effectively strengthen the internal gas retention time, improve the exchange of hot and cold effect. Kiln to use more lightweight materials, guarantee the production and management of the environment outside the kiln under the premise of reducing the wall thickness of the kiln to enhance the insulation effect。 slow cooling section to set a longer conducive to control of product defects。陶瓷的發(fā)展與窯爐的改革密切相關(guān)，一定結(jié)構(gòu)特點的窯爐燒出一定品質(zhì)的陶瓷。陶瓷窯爐可分為兩種:一種是間歇式窯爐,比如梭式窯。輥道窯由于窯內(nèi)溫度場均勻，從而保證了產(chǎn)品質(zhì)量，也為快燒提供了條件；而輥道窯中空、裸燒的方式使窯內(nèi)傳熱速率與傳熱效率大，又保證了快燒的實現(xiàn)；而快燒又保證了產(chǎn)量，降低了能耗
