A1: All products offered by OKorder.com are carefully selected from China's most reliable manufacturing enterprises. Through its ISO certifications, OKorder.com adheres to the highest standards and a commitment to supply chain safety and customer satisfaction.

Q2: How do we guarantee the quality of our products?

A2: We have established an advanced quality management system which conducts strict quality tests at every step, from raw materials to the final product. At the same time, we provide extensive follow-up service assurances as required.

Q3: What other products does OKorder offer?

A3: We offer a full range of refractory bricks, mortar, cement, ceramic fiber products, and more.

Q:Manufacture of various refractory magnesia brick mainly comes from Magnesium Oxide, what kind of ore?: Manufacture of various refractory magnesia brick Magnesium Oxide, mainly from magnesite.

Q:With different capacitance magnesia brick brick: Burnt magnesia brick is made of high quality sintered magnesia as main raw materials, paper pulp as binder. After mixing and high pressure molding, it is fired in a high temperature tunnel kiln over 1550 degrees celsius.

Q:What is the ratio of magnesia refractory bricks to brine? For example, what is the difference between the 97 and 95 with 92 brick brick brick material mixed with brine ratio?: In addition to the brine binder burned magnesia brick and sulfite pulp waste liquid, Magnesium Sulfate solution binder is generally around 3%

Q:Process for producing magnesia chrome brick: The fine powder compacts after calcination produced by magnesia - chrome ore grinding method, brick with magnesia coarse particles, are effective measures to eliminate the effect of loose. Compared with the common magnesia chrome brick, the magnesia chrome brick made by this method has lower porosity, higher compressive strength, higher softening temperature and higher flexural strength. Compacts with chrome magnesite powder, magnesia chrome brick by synthetic magnesia chrome sand made of high-temperature calcination, slag resistance and high temperature strength are better than other magnesite chrome brick.

Q:How to identify the fused magnesia brick and sintered magnesia brick: Magnesia brick have high refractoriness, alkali slag good performance, high load softening temperature, but poor thermal shock resistance. The sintering magnesia brick brick magnesite as raw material, crushing, proportioning, mixing, forming, in 1550 ~ 1600 degrees firing, high purity products firing temperature is over 1750 DEG C. Don't add chemical bond magnesia brick is appropriate in magnesia, through mixing, molding and drying.

Q:Magnesia brick: Mainly used for basic open hearth, furnace bottom and furnace wall oxygen converter steelmaking, the permanent lining of non-ferrous metal smelting furnace, high temperature tunnel kiln, calcined magnesia brick and cement rotary kiln, furnace bottom and furnace wall, glass furnace regenerator etc..

Q:The index of magnesia brick: Room temperature compressive strength≥（MPa）（15－25－）24.5－24.5－24.5－24.5－40－40－40

Q:High purity magnesia brick masonry mortar for what?: You try a mixture of aluminum phosphate. It itself is the main component of aluminum, which can not cause pollution. We use high temperature electric stove to bond with this.But this 800 degree won't be sintered. It won't sinter until more than 1000 degrees.

Q:How do you differentiate between the two clearly? Where is the key? Thank you: Magnesia brick (magnesite brick) basic refractories Magnesium Oxide content of more than 90%, with the main crystalline phase of periclaseGeneral can be divided into sintered magnesia brick (also called burnt magnesia brick) and chemically bonded magnesia brick (also known as the two major categories of not burned magnesia brick). Purity and high firing temperature of magnesia, due to the direct contact of periclase grains, known as direct bonded magnesite brick; made of fused magnesia bricks called electrically fused magnesite brick.

Q:Magnesite chrome brick, magnesia chrome brick indicators? What is the price?.: According to the actual situation, design the brick you need, and the price of brick is determined by the index.
