Precast shapes
Custom precast refractory blocks and shapes
From duty and drawing to mix selection, mould, casting, vibration, curing, drying and dimensional inspection of custom precast blocks.
Direct answer
A precast refractory block is cast, cured and dried in advance to an approved drawing and duty. Precasting moves critical mixing, consolidation, curing and inspection from site into a controlled production process.
Development inputs
Provide a drawing or verified dimensions, position, temperature, atmosphere, loading, support, cycling, transport and installation conditions. Openings, channels, inserts and anchors must be resolved before mould production.
From mould to dry-out
The selected mix is prepared with specified water, placed and consolidated, then cured and dried under control. Geometry, mass and critical dimensions are checked to the agreed specification.
- drawing approval
- mix-system selection
- mould manufacture
- casting, vibration, curing and drying
- dimensional inspection and dispatch preparation
Installation is part of the design
Weight, lifting points, tolerances, expansion joints and installation sequence influence the shape. A precast part must match adjacent layers and its support method.
FAQ
Short answers
Can you manufacture a single piece or short run?
A single shape, prototype or series can be assessed. Feasibility depends on mould complexity, material, inspection and quantity.
Are anchors always cast into the block?
No. Inserts and anchors are included only when technically required and defined in the approved drawing and specification.
