For caulking the lining of a ball mill, refractory mortar is generally recommended over refractory cement. The reasons are as follows: 1. Different bonding properties Refractory mortar is specifically designed for laying and caulking refractory bricks and linings. It has excellent plasticity and bonding properties, … Читать далее

Refractory slide gate bricks, also called sliding gate plates, are essential functional refractory materials in modern steel metallurgy. They are mainly used in ladle and tundish sliding gate systems to control the flow and direction of molten steel during steelmaking and continuous casting. Manufactured from … Читать далее

Refractory mud is also called refractory mortar. It is a high-temperature resistant bonding material primarily used for refractory brick masonry, bonding the bricks together, much like cement mortar used in conventional construction. Main Ingredients of Refractry Mud Refractory fine powder (high-alumina, silica, magnesia, etc., selected … Читать далее

Lightly calcined magnesia (light-burned magnesia) and dead burned magnesia are both produced from magnesite, but they differ significantly in calcination temperature, physical properties, chemical reactivity, and applications. 1. Definition & Calcination Temperature Item Lightly Calcined Magnesia (Light-burned MgO) Dead Burned Magnesia (DBM) Calcination Temperature 700–1000℃ … Читать далее

In refractory materials and specialized construction projects, the initial and final setting times of high-alumina cement are key performance indicators. Recently, with increasing demand for high-temperature kilns, metallurgical furnace linings, and chemical equipment linings, its setting properties have attracted increasing attention. The initial setting time … Читать далее
