New curing kilns and lifting equipment raise precast monthly capacity by 50%, shortening supply lead times for overhauls and emergency repairs.
Songrui’s refractory precast production line expansion has been completed and put into operation. Two curing kilns and dedicated lifting equipment were added, raising monthly precast capacity by 50% and supporting multiple projects simultaneously.
With the expansion, precast business now covers BF troughs, reheating furnaces and boiler linings, with shorter lead times from drawing confirmation to shipment — better support for both planned and emergency maintenance.
CNC cutting and milling are fully online; arch, door and other custom shapes hit ±1 mm precision with fast small-batch delivery.
Supplied fused-cast AZS and silica bricks for tank walls and regenerators; the delivery passed third-party sampling with zero defects.
Mixing and pressing upgrades on the MgO-C line improve strength and consistency, serving ladle and converter customers.
