Q:How much fireclay is needed per cube refractory bricks?
Normal refractory bricks need to use 70-80kg refractory mud each cubic . In fact, this can be calculated, because the volume of refractory bricks and refractory mud density can be measured. Of course, here is an important point, that is the size of the brick seam, 1mm brick seam and 3mm is significantly different. Sichuan brand refractory mud has many kinds, like high aluminum, clay, corundum, magnesia, insulation and so on, the dosage is different.
Q:What is the advantage for ceramic fiber material compared with refractory brick?
Heat capacity; excellent thermal shock resistance, good chemical stability, bearing sudden cooling and heating, without oven heating and cooling ,high speed, energy saving, is 1/8 of refractory brick, construction is simple. ceramic fiber materials and refractory brick belong to refractory insulation materials; low thermal conductivity: Low bulk density, ceramic fiber material is a new type of lightweight thermal insulation material, is one of the 10 points of lightweight refractory brick,
Q:The matching ratio of masonrying refractory bricks cement
Size of brickwork joint: Vertical and horizontal seam are 2 ~ 3 mm. The ratio of seam mud: Refractory clay mud 100%; per m3 dry, clean industrial water 400 ~ 600t/, no more than 3mm
Q:several refractory brick of rotary kiln several is damaged, how many refractory bricks should be replaced?
In general, if the brick inside the kiln break or loose core, the bricks of whole circle should be replaced, if only mend by replacing a damage part is also ok, but the service life is shorter.
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:How to built refractory bricks as fitting between square and circle ducts
Build a big mushroom, and build the legs as square
Q:What material is sk-34 on the refractory brick
Electric power; refractory bricks, castable refractory, building materials, chemical, glass, ferrous metals and other industries required refractory and insulation materials, all kinds of thermal insulation cotton products, thermal insulation brick, aluminous refractory cement, perlite and other unshaped refractory materials have been the best-selling products
Q:why the color of refractory brick is white after high temperature firing when the meteorite is black after the burning?
There are different reasons. Meteorolites can mainly be divided into three types, iron meteorites (iron nickel alloy): Stone meteorites (the main component is silicate), and stony iron meteorites(the mixture of iron and silicate)
Q:How to adjust the temperature in the 160 meter tunnel kiln?
Increase will reduce the amount of fuel added to the kiln, then the temperature will change.
Q:What is the raw material for the production of refractory bricks?
Refractory raw material, sodium silicate as a binder, and lightweight aggregate, magnesium sand, magnesia calcium. Magnesium Oxide, bauxite, and then lightly burn: Hard refractory clinker
