The flying development of light simple fireproof stuff basically already satisfied the need of furnace of kiln of contemporary pottery and porcelain. Kiln aspect is changed gently character, makings of kiln car line is changed gently character, kiln is provided light-duty change make kiln furnace weight is reduced greatly, reduce the demand of pair of kiln furnace steel structure and fundamental foundation thereby, the carriage that is helpful for assembling type kiln furnace and build, also be helpful for automata. Additional, the harbour quantity of heat with light simple fireproof inferior stuff and good adiabatic performance, the environmental protection that is helpful for kiln furnace is energy-saving. In the design of worker of contemporary kiln furnace in kiln furnace besides should apply advanced full automatic control technology, still use new-style, have energy-saving model the material that build furnace, change in order to boost the small system of kiln furnace, energy-saving change.
1, brick of light qualitative clay
Argillaceous brick is the grog after reaching its calcination by saggar, via smashing, burden, shape and in 1300 ～ 1400 ℃ fall to contain ～ firingly 48% (after burning) siliceous aluminous simple fireproof stuff. Belong to weak acidity, thermal stability is better, its loading bate begins temperature not under 1250 ～ 1400 ℃ . Argillaceous brick workmanship is simple, the raw material that make a brick resourceful, crop big, price is low, reason applies extensively at furnace of kiln of pottery and porcelain. Brick of light qualitative clay is chosen to regard as in the design whole thin model the brick end the shop of kiln of bricky roller path (each Duan Jun lays a foundation with brick of light qualitative clay) , can satisfy the requirement that construct pit already, can reduce the cost that construct pit again, with smoke evacuation paragraph for exemple, if plan institute is shown.
2, light qualitative tall aluminous brick
Content > the siliceous aluminous qualitative refractory products of 48% calls tall aluminous brick. As a result of it fireproof degree, loading bate begins temperature to all compare argillaceous brick tall, gao Yun makes use temperature be 1650 ～ 1670 ℃ , multi-purpose the firebox at furnace of kiln of pottery and porcelain and firing the high temperature place of the belt. Light qualitative tall aluminous brick has taller porosity, bulk density is low, many coefficient of thermal conductivity is lower than relevant compact data, low-cost, apply in heat preservation of furnace of kiln of pottery and porcelain wider. This design is in firing take a large number of choosing to get together gently character light ball brick, include side wall brick and condole top brick, satisfied high temperature resistant requirement, reduced kiln body quality at the same time, realized kiln body to be changed gently character. Additional, the burner that contacts with blaze is in, chose Molaishi to combine tall aluminous qualitative brick.

3, fireproof fiber
Fireproof fiber shows use temperature is in commonly 1000 ～ the fiber material of 1100 ℃ above, its sort basically has: Fiber of tall aluminium of general and siliceous aluminous qualitative, much crystalloid, 2 zirconia fiber, carbon fiber. Be in at present pottery and porcelain is good, bulk density is small; OK also will come loose cotton suppress becomes felt, carpet, board wait for goods of other opposite sex, use in furnace of kiln of pottery and porcelain. Many fiber blanket, beaverboard and tall aluminium were used to come loose in this design cotton, referenced graph 4, graph 5.
Fireproof fiber pledges gently with its, tall fireproof degree, shake of low coefficient of thermal conductivity, low accumulation of heat, heat-resisting, anti-corrosive, fight machinery vibration and sound-absorbing performance is good wait for superior performance to get the favour of worker of broad kiln furnace. Felt of fiber of many application pottery and porcelain, blanket, board wait for furnace liner and kiln body, can improve the thermal efficiency of kiln furnace substantially. The data covers [3] : Some factory constructs pit of type of shuttle of liner of fiber of a pottery and porcelain, firing temperature is 1250 ℃ , temperature of kiln wall appearance is 50 ℃ , kiln carries temperature on the head to be 60 ℃ , the thermal efficiency of every tons of finished product is 13% , energy utilization rate is 48.1% . The accumulates heat and heat loss due to radiation to hold overall hear rate 20% ～ of original kiln car 25% , 8% ～ can be reduced after using fiber of pottery and porcelain 15% .
Zhengzhou flourish fills the fireproof material that serves as major to produce manufacturer, we have rich kiln to furnace is built and transform experience, if you have pertinent question and demand but department of market of our Rong Cheng has the incoming message seek advice, we can act on cordial attitude of attending to guests to offer professional conduit solution to you.
