Q:High alumina refractory bricks (Universal arc) weight for hot metal ladle

Climbing, C23B ladle generally use T3 ladle bottom brick, brick wall with C23 package, C231 Some permanent layers are built from high alumina bricks, and some are built from castable refractory, T82, T43. Specific size can be checked according to the type of brick

Q:Is fireclay brick acidproof? Does clay brick anti corrosion when it's used to build chimney lining?

Refractory bricks anti acid and alkali after high-temperature calcination, and anti-corrosion won't be a problem

Q:should clay or refractory cement be used to lay refractory bricks?

structure strength of this brick lining is not good, apply some refractory mud, only use some virgin clay and corundum, many of the traditional approaches are very simple, mullite and carbon slurry, the specific products are selected according to the selected material and water glass or organic binder. binding agent can choose phosphate, silica and high alumina, clay is one part of the refractory clay, there are many kinds of refractory slurry according to the material, clay-based mud does use refractory cement and corrosion resistance is low

Q:Are there any good improvement measures for the always collapse of the previous vaulted tunnel kiln built by refractory bricks?

refractory castable integrally casting

Q:What's the reason of cracks in refractory bricks?

The relative density is high, and high temperature heat treatment and increase the strength of qualitative brick, for 10 days, then only the shorter time for heating and drying and dehydrating, you can smash a brick if it's a long time! There will be a stress loose phenomenon making bricks now, the internal density of these crack bricks are not the same, in addition to the effective drying, dehydrating and heating treatment, the time distance is small, basic bricks and finished bricks adopt line production, when drying, the water is also evaporated at the same time, the central density should be high ! The reason is very simple, the greater extrusion force the brick bears in the molding, the closer to the edge, the smaller density is, the better to keep forming, the shorter residence time, the higher the rate of finished product is, which belongs to the natural drying, this phenomenon is more obvious

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:What raw materials are used for making refractory bricks

That is silicon aluminum refractory brick&#47, it can be divided into five types:thermal insulation refractory brick, alkaline series refractory brick, refractory brick containing zirconium, carbonaceous refractory brick&#47. Refractory bricks are divided according to the ingredient of refractory. Refractory bricks are generally made from refractory clay (kaolin) or other refractory materials.

Q:What kind of coal should be used to burn refractory brick? and how many calories smoke is suitable?

It can't be the surface of coal, at least it is coal seed.

Q:Can common cement mortar be used to build the lining of chimney refractory brick?

No. You have used fire bricks, which shows there is a certain temperature inside, you'd better use refractory cement
