How to choose a refractory stacking site?

Flat ground: The site for stacking refractory materials should be kept flat to prevent the materials from tilting or collapsing due to uneven ground.

Moisture-proof measures: Refractory materials should be stacked away from humid areas, and the stacking area should have good drainage facilities to prevent moisture from seeping in.

Good ventilation: The stacking yard needs to maintain good ventilation conditions to avoid moisture accumulation and cause the materials to get damp.

Refractory stacking techniques

Classification and stacking: According to the requirements of different parts of the kiln, the refractory materials are stacked separately and classified by composition, specifications and size.

Stack in construction order: stack the refractory materials for the first construction site as close to the transportation line as possible.

Stacking identification: All stacks should be marked with the model, quantity, main dimensions and usage location of the materials, and be affixed with detailed labels.

Aisle width between stacks: entrance aisle width shall not be less than 600mm; transport aisle length shall be 2000~3000mm; distance between stack and wall shall not be less than 500mm.

Requirements for stacking refractory materials

Neat and stable: Stacking must be neat and stable to facilitate secondary search, use and transportation.

Materials with unit weight less than 12kg: standard refractory bricks, thick wedge-shaped refractory bricks, right-angle refractory bricks, etc., with about 12, 16, or 20 bricks arranged in each layer, and the height shall not exceed 1.9m.

Materials with a unit weight exceeding 12kg: rectangular refractory bricks or special-shaped refractory bricks, with the same quantity and style in each layer, and the height shall not exceed 1.8m.

Standard refractory brick stacking method: If the brick stack uses 5 side bricks as a group, then four groups of side bricks are a square stack, with 20 bricks per layer and a height of 15 side bases. Each brick stack contains 300 bricks.

Stacking method: The stacking of refractory bricks can be placed flat or sideways. According to different specifications and sizes, refractory bricks are stacked into independent brick piles. At the same time, some refractory bricks with special shapes must be placed flat.

Stacking stability: Regardless of the stacking method used, the direction of the upper bricks must be opposite to that of the lower bricks to ensure the stability of the stack.
