What are the types of refractory bricks?
There are many types of refractory bricks available. Those are Andalusite Bricks, Dense Silica Brick for Glass Furnace, Corundum Mullite Brick, Corundum Brick, Fireclay Brick for Coke Oven, Fireclay Brick for Blast Furnace, Low Creep High Alumina Brick for Hot Stoves, High Alumina Bricks for Blast Furnaces, General Refractory Fireclay Brick, General High alumina refractory brick, Insulating firebrick, Silica bricks-coke oven refractories, Magnesia brick, Magnesia Bricks for Cement Industry, High Alumina Bricks For Cement Industry, Fused cast Bricks, Sillimanite Bottom Blocks, Low Porosity Fireclay Bricks, Zirconia Bricks, General fireclay brick for steel industry, Refractory insulating fire brick B&C series, Insulating bricks etc.
What is the Bulk density of refractory brick?
It will be around 25 to 35kN/cum depending on the type of contents in Refractory brick. Regards N. Suresh kumar
What do you need to note while laying refractory brick?
Notes about Fire Bricks Laying During Furnace Construction1. Construct the furnace either by one kind of refractory brick or by two kinds of brick, the required matching percentage of brick in theory may differ from the actual percentage affected by distortion of cylinder. So there is no need to use bricks totally as the theoretical required amount while constructing the furnace. It's a key point to lay the big side of brick close to the cylinder when doing the construction, and the bricks should be laid straightly and there had better no gaps between each two bricks. Fill the gaps and distortion with mortar, the repair seam line should not be too hard in case of breaking of bricks.2. Abandon the twisted refractory bricks which are out of distortion standard, making sure that the bricks are tightly bonded and no looseness. While construct the furnace by bricklaying machine, the upper brick especially alkaline brick can not be given too much pressure, because alkaline brick's strength at normal temperature is relatively lower. Avoid bricks broken by uneven compression, so that to avoid kiln body falling off while working.3. While laying alkaline refractory bricks, watering or grouting the brick upper surface is prohibited. The well up cement mortar should be cleaned before it hardens.4. Construct the furnace strictly according to each brick matching method to avoid distortion of brick block and kiln body working out of balance, furthermore to avoid affecting working cycle.5. During the construction, check carefully and immediately both annular flatness and axial flatness according to the datum line in every circle and section. Parallel vertical seam line with furnace axis, parallel annular seam lines with each other, and make the parallel annular seam line vertical with the furnace axis. If the furnace body distorts or the refractory bricks are irregular, adjust the body by steel plate and the bricks by cement mortar. The steel plates should just fit with the bricks (the length and height of steel plate should be 5mm smaller than those of brick).6. When finish semicircle construction of the furnace, firstly check the deviation of vertical seam line with datum line and annular seam line with datum line, then lay one tier or two tiers of bricks, set up the mandrel and turn the furnace by 900. Construct the left half furnace on the other side, set up another mandrel while finishing one section. Turn the furnace after the mortar hardens.For more information about refractories, go to yilongrefractory.com
How do you Seal brick fireplace?
Use refractory cement.... see above
What raw material are put into a blast furnace?
The blast furnace is a huge, steel stack lined with refractory brick, where iron ore, coke and limestone are dumped into the top, and preheated air is blown into the bottom. The raw materials require 6 to 8 hours to descend to the bottom of the furnace where they become the final product of liquid slag and liquid iron.
What are the chemical and physical indexes of magnesia carbon brick?
There are different grades of magnesia carbon brick. And it is usually used for the lining and tap hole of steelmaking converter, the sidewall and slag line of high power electric ARC furnace and ladle slag line.
How much does a house furnace weigh?
About 500 lbs for furnace and about 10,00 ibs for a brick house
What is linear change on reheating of refractory?
Linear change on reheating means that the size of refractory products is irreversible changed when the refractory products are heated to high temperature. A positive value indicates expansion which is called expansion of linear change on reheating; negative value indicates contraction which is called contraction of linear change on reheating. Zhengzhou Sunrise Refractory Co., Ltd. is mainly engaged in the research and development of refractory products.Sunrise can provide excellent quality refractory products which contain Fused cast AZS 33#,36#,41#, fused cast α-βalumina, fused cast high zirconia block, fused cast skid rail block, silica brick, glass mould brick, magnesia brick, zircon brick, zircon mullite brick, mullite brick, sillimanite brick, fused corundum brick, high chrome brick, chrome corundum brick, chrome AZS block.

Best Fireplaces are made of what?
Brick is my favorite, but the firebox will be made of firebrick, and not ordinary building brick. Some people prefer the appearance of cut stone or field stone, but the firebox will still be firebrick (refractory brick)
What is a refractory table?
A refractory table has leaves at ends, not in center....Expandable.The correct name is a refectory (dining hall) table. The answer is basically correct for that term. Refractory describes heat resistant and/or insulating materials used in kilns, furnaces, wood stoves, etc (e.g. refractory brick). I suppose you could make a table out of firebrick.
What is cold-crushing strength of refractory materials?
cold crushing strength of a refractory brick is gross compressive stress required to cause fracture. Maximum Structural load that a material can withstand without fracture
