Magnesite Dolomite brick offers good thermal resistance and anti-spalling performance purifying the steel by removing sulfur and phosphorus; while used in cement rotary kilns providing good coating protection to the kilns.
18-09-2020· Cement Rotary Kiln. First, let's take a look at the kiln mouth. It is best to use refractory materials resistant to thermal shock at the kiln mouth. Such as wear-resistant and heat-resistant high-alumina bricks or steel fiber reinforced castables and low-cement high-alumina castables. However, in large kilns with extremely high kiln mouth ...
Originally used in basic-practice steel converter vessels in Europe decades ago, burned dolomite brick was tar-impregnated to increase slag resistance and reduce penetration. Resin Bonded Dolomite Brick: In cement kilns, dead-burned dolomite brick provides optimum compatibility with the cement clinker in the burning zone.
In addition, dolomite bricks have advantages of forming stable kiln coating, because it is resistant to corrosion of the cement clinker, thus reducing thermal loss, saving energy, and improving economic benefit. Resistant to erosion of basic slags and iron slags. High refractoriness.
Dolomite bricks often compete with magnesia bricks and find application in the steel, cement, and lime industries with steel mills preferring pitch-bonded, tempered grades. On the other hand, sintered dolomite products are used in the manufacturing of the most important materials for the lining of converters and more and more for ladles. Fired ...
Fired Dolomite bricks are only used in the shaft and rotary kilns of the lime and cement industry. Dolomite is a double carbonate of calcium and magnesium with the chemical formula CaMg (CO3)2 and is used as primary raw material for dolomite bricks. Fired dolomite bricks are far less sensitive to hydration than pitch-bonded dolomite bricks ...

Therefore, they are suitable for use in cement rotary kilns. Bring it. 1. Dolomite Brick. Dolomite bricks are made of dolomite sand that is calcined from natural dolomite. Dolomite brick contains w (CaO) ≥ 40%, w (MgO) ≥ 35%, and also contains a small amount of SiO2, Al2O3, Fe2O3 and other impurities.
Dolomite Brick. Dolomite bricks are regarded as the substitute of magnesite-chrome bricks which are widely used in cement rotary kilns. The biggest characteristic of it is the price advantage and the stable kiln skin formed by it. However, this kind of brick has poor hydration resistance. It is easy to react with water vapor in the air during ...
Advantages of Using Dolomite Brick in Cement KilnsThe important component material of dolomite brick is dolomite. The theoretical composition of pure raw materials i
Dolomite bricks are refractory products made of calcined dolomite sand. Usually dolomite brick contains more than 40% CaO, more than 35% MgO. If the CaO/MgO ratio in the brick is less than 1.39, it is called magnesite dolomite brick.
18-03-2021· Dolomite bricks are mainly used in the burning zone of stainless steel refining furnaces and cement kilns. Only a few cement kilns in my country use imported dolomite bricks. Magnesia-calcium Brick. There are two types: one is a magnesia-calcium brick produced ...
Zhengzhou Rongsheng Kiln Refractory Co. Ltd, is a professional dolomite bricks manufacturer. It is located at the foot of Mount Song, a place fulling of natural refractory materials resources. Besides the natural advantages, it is neighboring Zhengshao Expressway and at the transportation hub, near Longhai and Jingguang railway lines.
When used in cement rotary kilns, these bricks provide good coating protection to the kilns. Application: Magnesite Dolomite brick is applied mainly in refining furnaces such as AOD, VOD, and ladles. Also applied in the burning zone of cement refractory kiln as an alternative to magnesite chrome brick.
Magnesia Dolomite Zirconia Bricks Description One of MgO-CaO series refractory material's shortcoming is weak thermal shock resistance. To improve thermal shock property of magnesia dolomite bricks, zirconia powder, zirconia grain, calcium zirconate and magnesia calcia zirconia composite are added into magnesia dolomite raw material. Various tests suggests that when 2% of ZrO2 is added into
04-06-2021· In the field of cement industry, due to some reasons, some enterprises in our country still use magnesia-chrome bricks in the firing zone and transition zone of cement rotary kilns, while dolomite bricks have excellent high temperature resistance, kiln …
Therefore, they are suitable for use in cement rotary kilns. Bring it. 1. Dolomite Brick. Dolomite bricks are made of dolomite sand that is calcined from natural dolomite. Dolomite brick contains w (CaO) ≥ 40%, w (MgO) ≥ 35%, and also contains a small amount of SiO2, Al2O3, Fe2O3 and other impurities.
Dolomite bricks were installed in the burning zone at the same time, but this brick grade exhibits sensibilities to CO 2, sulphur and ... brick for cement rotary kilns. Figs. 3 (rotary kiln with 4-stage preheater) and 4 (rotary kiln with 4-stage preheater and pre-calcination
