What is the alumina mortar?
High alumina refractory mortars VITSET ready mixed high alumina refractory cements / mortars are suitable for jointing, coating, and patching in all high temperature applications from 1450°C / 2640°F up to 1860°C / 3380°F. They are air-setting, with outstanding bonding properties at ambient and operating temperatures.
What is high alumina bricks?
A high alumina brick / refractory brick is a shape made from refractory ceramics. It is used in lining furnace kilns, fireboxes and fireplaces. Its primary purpose is to withstand high temperature and also to retain the heat for greater energy efficiency.
What is high alumina castable?
Basically, the high alumina castable refractory consists of monolithic refractory materials. Basically, they are made of high alumina aggregate and powder, mixed with a binder and water reducer. Moreover, the Aluminum Oxide or Al₂O₃ content in this refractory material is over 48%.
What is heat setting mortar?
The two general classes of refractory mortars are air-setting and heat-setting. Air-setting mortars take a rigid set upon air drying, while heat-setting mortars set at high temperatures by sintering, or developing a ceramic bond.
Which material is best for cold gunning in the ladle?
Ladle gunning mix choose high grade magnesia sand, bauxite and spinel stone as raw materials, adding the unique binder and additive, mixed by scientific rate.
How much heat can a fire brick take?
Fire bricks and masonary bricks are manufactured with different ingredients. Firebricks are blocks of refractory ceramic materials used to line fireplaces, fire boxes and furnaces. They are different from regular masonry bricks because of their ability to withstand temperatures up to 1,800 degrees Fahrenheit.
What mortar do I use with fire bricks?
OVERVIEW. Sakrete® High Heat Mortar is a dry, medium-duty mortar ideal for setting masonry units in fireplaces, fire pits or chimney applications such as setting clay flue liners and paring a smoke chimney chamber.
What is torpedo ladle?
Torpedo ladle cars are used to transfer molten iron from the iron-making section of the plant to the steel-making section. Under normal conditions, the residence time of the molten iron in the ladle is two to four hours, and the distance traveled is usually less than one-half mile.
What is ladle furnace slag?
Ladle slag is produced during the secondary refining of steel and is a valuable source of calcium oxide for the cement industry. Ladle furnace slag is produced through the addition of lime (CaO), and dolomitic limestone (CaO. MgO) in the electric furnace.
What is the use of high alumina cement?
Uses of High Alumina Concrete for Refractory Generally, this refractory product is widely used in sewer infrastructure and marine construction. Besides, it is also used in refractory concretes for furnaces, boilers, kilns, and chimneys.
What are the advantages of high alumina cement?
Advantages of High Alumina Cement: It can withstand high temperatures. In cold weather conditions, frost action is reduced due to heat evolved is more during setting. It is highly reactive and has a very high compressive strength. Good resistance to fire.
Can I use regular mortar for fire brick?
Domestic Fireplace Mortar is a premixed and ready to use regular mortar. It was developed for installation of firebrick in masonry fireplace installations. It also has many other uses such as in chimneys, boilers, incinerators, furnaces, kilns, etc.
Is there a special mortar for fireplaces?
QUIKRETE® Fireplace Mortar (No. 8620-21) is a silicate based refractory cement caulk for tuck-pointing damaged fireplace mortar joints and repairing cracked or chipped firebricks in fireplaces and wood-burning stoves.
