Different raw material sticks the thermal stability of earthy firebrick, and same raw material is different slop is fineness the thermal stability that sticks earthy firebrick. Exposition and argumentation base pink performance is quality to clay the influence of firebrick thermal stability.
The result shows feldspathic qualitative clay to pledge firebrick has taller thermal stability, of slop fineness control is in residue on sieve of 10 thousand aperture 0.38% ～ 0.76% , be helpful for sticking the progress of earthy firebrick thermal stability, apply moisture content to be 6.5% ～ 8.5% , base pink grain is given priority to with 0.25 ～ 0.125mm, be helpful for sticking the progress of earthy firebrick thermal stability.
Argillaceous brick firebrick forms composition content mediumly
Saggar brick is to show silicon pledges content is in the 30 one firebrick of 46% , it makes oxidizer by the grog with saggar place firing damask, make adhesive in order to combine clay be made. Argillaceous brick firebrick forms composition content mediumly to have want severe according to to ask to undertake.
Production knot is earthy the main raw material of firebrick is saggar. Clay is the mineral resources of earthy record, after adding water, can form but model mud is round, dry hind can maintain already some appearance, petrosal hardness is had after R of 9 high temperature is burned.
In addition, the mineral resources foreign matter that wants ration always is contained in clay, basically quartz, micaceous, pyrite, feldspar and organic matter wait. Foreign matter can drop the quality of saggar, it is harmful normally, especially iron qualitative impact is big.
Alkaline kind of Na20, k20 exists with micaceous state, can improve the sex that burn orange, when damask is burned, can get school for close finished product, add up to a quantity to be less than normally 2% when the harm is not severe.
The content like CaO- is less than 11.5, 00, and distributing contrast is equably, drop won't austerely so the fireproof sex of raw material.
Written guarantee the Ti02 that should decide an amount is contained in earth, its fertilizer exists with mineral resources of golden bar stone, contain dish be less than 1.5% when very big to writtening guarantee earthy mass is done not have impact, often decide its content from side not only in chemical analysis, and calculate in A1203+ TiO: ? Does earnestly ancienting name for a water catltrop read Song?
When gross of the impurity inside clay exceeds 6% , because fireproof degree drop to cannot serve as fireproof raw material.
The organic matter in saggar adds up to A to shake very big, tall can amount to 5% above. After the fireproof ties land that finished product of production ties land uses asks damask is burned A1z contains location not less than 30% , fireproof degree not under 1580 degrees. Annals of fireproof data limited company is in furnace of kiln of Zhengzhou Rong Cheng industrial dedicate oneself to the service of one's motherland, industry of service high temperature is oneself, we bear tens of year the technology is accumulated, active and before look up ground is high temperature industry will make tomorrow make brand-newly, become hard " boiler and expert of liner of furnace of hot project kiln " .
