specific designs are custom made to fit individual steel shop ladle sizes and metallurgical conditions. Diverse Product Portfolio BARRICADE SLB 128 brick contains high-purity fused magnesium oxide, 12% carbon, and a unique dual-carbon antioxidant package. BARRICADE SLB 128 utilizes HWI's latest technology for high corrosion resistance for
Magnesia chrome bricks are mainly used in metallurgical industries, such as the construction of flat furnace tops, electric furnace tops, refining furnaces and various non-ferrous metal smelting furnaces. The refractory product for RH furnace is mainly magnesia chrome brick.
Magnesium carbon refractory brick is based on the high melting point alkaline oxide magnesium oxide (melting point 2800 ℃) and difficult to be infiltrated slag slag high carbon material as a raw material, add a variety of non-oxide additives.
Aluminum Magnesia Carbon Brick Introduction Aluminum magnesia carbon brick refers to a refractory product made of super high alumina bauxite or corundum sand, magnesia sand and flaky graphite. Aluminum magnesium carbon refractory brick is a lining fire product, refractory aluminum magnesia carbon brick is made of super high alumina bauxite or corundum sand, magnesi
the manufactures have a tendency to produce commodities (mainly MgO-C). In order to keep the existing market share as well as increase sales some producers have invested in R&D to improve refractory performance as well as to reduce the refractory specific cost. Very close relationship with the customers and a strong technical approach have

On the cut sample one can see the zonal infiltration of corrosive medium (Cu(CuO x)-Na 2 O-2SiO
Chromium-free refractory bricks are produced and preferred in the last 20 years in order to solve the environmental pollution caused by use of the magnesia-chrome brick in cement kiln . In recent years the production of MgO-spinel bricks and MgO-hercynite bricks as alternatives to MgO-chrome brick have become widespread .
: Development of Heat Treatment Refractory Bricks Using Local Nigerian Clays . crucibles, incinerators, insulation, and furnaces, particularly metallurgical furnaces. Therefore, a refractory is a material that will retan ts shape strengh and chemcal dentty when subjected to high temperatures and is used in applications
Compared with magnesium chrome bricks, it is featured with good thermal shock resistance, volume stability under high temperature, and high refractoriness under load. Chrome Refractory Bricks Applications. Magnesia chrome brick has a wide range of application. It can be used in the metallurgical industry, architectural material industry, and
These bricks may have high boron oxide content (more than 0.1 % B2O3). These bricks have good hydration resistance. These bricks are made with lower purity natural DBM with MgO content of 95 % or less. These bricks have lower refractoriness as compared to bricks made with very pure magnesites (MgO content more than 98 %).
Description : Magnesia Refractory Bricks,Basic refractory magnesium oxide content in more than 90%, the main crystalline phase to pericase. Magnesia brick have high refractoriness,alkali slag good performance, high load softening temperature, but poor thermal shock resistance.
The price of one refractory brick is $400-1300 per ton. Dolomite Refractory: Dolomite bricks are made up of MgO 25-45%, CaO 35-65%, and other materials. They have high refractoriness, Thermal stability at high temperature and slag resistance. They are more porous, more shrinkage softness and less strong.
Abstract. Microstructural analysis of MgO—MgAl 2 O 4 refractory bricks corroded at 1400-1450°C by calcium aluminosilicate slag reveals secondary spinel, monticellite, merwinite, and MgO as microscopic corrosion products, generally forming in this sequence as the brick is penetrated.

Magnesia bricks are basic refractory brick materials whose MgO content are more than 90% and adopt periclase as the principal crystalline phase. Magnesia bricks generally can be classified into sintered magnesia bricks (also known as fired magnesia bricks) and chemically bonded magnesia bricks (also known as non-fired magnesia bricks).
