Hot-Blast Stove Checker Bricks from China
Hot-blast stove grid bricks are listed in Sinosteel Luonai’s public iron-and-steel portfolio. Checker geometry, flow passages, material grade and dimensional tolerances must be matched to the stove design rather than selected from an image alone.
Published catalog reference. Final grade, dimensions, properties and availability are confirmed against the RFQ. Official source.

Procurement FAQ
Questions buyers often ask
Can the checker pattern be quoted from a photograph?+
No. A controlled drawing is required because hole pattern, dimensions, tolerances and assembly arrangement affect the complete checker structure.
Is one material grade used throughout the checker chamber?+
Not necessarily. The design may specify different materials by temperature and service zone.
Can pre-assembly or dimensional inspection be requested?+
Include the required scope, sampling plan and acceptance criteria in the RFQ so feasibility can be confirmed.
