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 … 続きを読む

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 … 続きを読む

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℃ … 続きを読む

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 … 続きを読む

The following types of refractory bricks are primarily used in coke oven walls, depending on the location of the wall and operating conditions: 1. Silica Brick – Main Material ✅ Main Features: SiO₂ content ≥ 93% High refractoriness under load (>1650°C) Good high-temperature volume stability … 続きを読む

Introduction to Refractory Boiler Bed Material Refractory boiler bed material is a high-performance granular material used in fluidized bed boilers, particularly in circulating fluidized bed (CFB) and bubbling fluidized bed (BFB) systems. It forms the foundation of the fluidized bed, supporting the efficient combustion of … 続きを読む

As a key refractory structure in the steelmaking process, Refractory Materials For Cast Ladle Lining must have good erosion resistance, thermal shock resistance, slag resistance and high temperature strength. According to the structure of the working layer and the use position, the lining of the … 続きを読む

Ladle bricks are refractory bricks used for lining the ladle (steelmaking transfer container), mainly used to withstand the erosion and thermal shock of high-temperature molten steel. According to different parts, use environment and performance requirements, there are several common types of ladle bricks: Common Types of … 続きを読む

High-aluminum low-cement castable The main raw materials of high-aluminum low-cement castable are high-aluminum bauxite, with low-cement binder, refractory aggregate, powder and sodium tripolyphosphate and other additives. High-aluminum bauxite provides high alumina content to ensure fire resistance and wear resistance; low-cement binder reduces low melting phase … 続きを読む

What is Ladle Covering Agents: Ladle covering agents are functional materials used to cover the molten steel surface in ladles during steelmaking, with core functions including: Thermal insulation: Reducing heat loss to maintain pouring temperature stability; Anti-oxidation: Isolating air to prevent secondary oxidation of molten … 続きを読む
