Q:Tunnel kiln firing refractory brick by 0 against the good rely on
Modern advanced kiln has high temperature strength and good thermal shock resistance, better environmental protection, is the most economical and efficient kiln. (3), good resistance to gas erosion, due to tunnel kiln's flue gas discharge temperature is generally not higher than 250℃. In order to guarantee the normal temperature system and pressure system of the kiln. Its firing temperature is at 1200-1900℃: (1) or even higher, the requirement for the firebrick, compared with the intermittent kiln, is an important thermal equipment in refractory industry. It is a kind of energy-saving kiln. Tunnel kiln is a kind of kiln that can continuously produce and has high degree of automation.
Q:What is the refractory brick of the electric furnace?
there is no problem if it can be dismantled. And refractory brick material of every place is not the same, life is not the same. Buy some for backup , and change it once it is broken, there is no standard, the lining can be hit, as long as the induction coil can be fixed
Q:how to distinguish the quality of high alumina refractory brick when you buy it ?
see the gap between the bricks and between kiln roof and kiln wall, etc.. 6, the pressure and the volume density of Pei brick and brick Pei size, appropreate matching of high alumina powder and high aluminous aggregate and other materials, the drying and time, and the mud trapped material humidity 1. 7, to reach the requirements of production. 4, the order of loading Pei brick into kiln . should prevent the lack of a scene , the requirement , mixing time, different procedure and the order of the adding of raw materials of high alumina brick. 3, drawing plan and lack of edge of high alumina brick . 5
Q:Is the quality of refractory brick influenced if it is soaked by water
No refractory brick is not afraid of water
Q:What refractory mortar is better if masonrying 4 meters height and 114 mm width of refractory brick
The selection of refractory mud should keep the principle of homogeneous phase with refractory bricks, that is to maintain the same material, according to the suitable temperature, choose appropriate binding agent compensation measuring forging Yao tic surprised boxing super man (phosphate, sodium silicate, or other organic combination), composite high performance admixture, it can be combined better in high temperature.
Q:Is the diameter of 2.5 meters of the calcium aluminate powder rotary kiln referred to the inner diameter of the refractory brick?
No, it should be outer diameter.
Q:what is consequence of high load and soft low of high alumina refractory brick ?
softening, if not up to the design requirements, may cause vicious incident like the collapse of the stove in use. the full name is softening temperature under a fixed load, as the name suggests, it is the softening temperature after adding the load.
Q:The shape and size of general used refractory brick
According to the national standard, the outline dimension of mechanism red brick is: length is 240mm, width is 115mm and thickness is 53mm. That is: 240mm * 115mm * 53mm. The shape and size of the ordinary refractory bricks are: Length is 230mm, width is 114mm and thickness is 65mm, that is: 230mm * 114mm * 65mm. The shape and size of special refractory bricks are: 345mm*328mm*97mm.
Q:What materials mix mortar to build walls (with bricks)? The more burned the harder
Refractory mortar
Q:The advantages of using alkalinty refractory brick?
Magnesia chrome and other spinel refractories alkalinity refractories; (2) the alkalescent chrome magnesite refractories, alkaline solvent resistance is strong, usually refers to the magnesia refractory material, dolomite brick and calcareous refractory materials, dolomite refractory materials and lime refractory materials, acid flux or acid refractory chemical reaction. Mainly used in alkaline steel furnace and non-ferrous smelting furnace. Alkaline refractory material at high temperature for alkaline slag. Mainly as the following categories, but the acid slag, forsterite refractories and magnalium: (1)strongly alkaline magnesia brick, magnesia carbon brick and cement kiln
