Refractory Brick Production Process

Desicription: The refractory bricks production process from material ,mixing, pressing ,drying, burning ,cooling and packing and shipment.

Title: Refractory Brick Production Process

Keyword: Refractory bricks,  production , process

  • The production procedureof a refractory brick is divided into the raw material selection, calcining, forming, crushing, batching, mixing, placing material, molding, drying, burning, assessment and packing.

  • The rate of refractory brickand raw material price, physical and chemical index, and production procedure is quickly specified.

  • Raw material choice, beneficiation, and purification, High purity raw materials are the premise for producing high-quality refractories.

  • Natural mineral materials usually comprise lean ore and rich ore, with unequal composition and large-quality variations, sometimes directly usage of refractories will cause problemsand weak quality, even can not be utilized, therefore, mineral processing, enrichment, and category are essential.
  • Calcining, except for some raw materials, most of the raw materials utilized as refractory aggregatemust be calcined at great temperatures.

  • A series of physical and chemical reactionsare generated when the raw material is calcined, which plays a vital role in enhancing the composition, increasing mineral composition and structure of the refractories, and assuring the volume stability of the refractory and the precision of the apparent size.

  • The indexes of material sinteringcontain apparent porosity, bulk density, and water absorption, etc.
  • Sorting, crushing, and proportioning,the raw material requires to be screened after a crushing and grinding, because the semi-finished material is graded by various sizes of powder, and ensures received the dense body with the greatly compact.
  • Each variety of equipment can generate various fineness of finished powder by grinding, 80 mesh -425 mesh, 500 mesh -2000 mesh, the finest can achieve about2500 mesh.

  • Mixing, placing material, in order to homogenate the components and particles of raw meal and clinker, It is essential to mix and add binder at a similar time to improve the bonding strength of the semi-finished material.
  • After molding, drying, and press by great pressing equipment and molded, the green refractory bricks should be placed for a particular time to dry.
  • Burning, the complete product was sintered by high-temperature sintering at a high-temperature kiln.
  • Checking and packing.
