| Production | Precast to drawing, cured and pre-fired |
Refractory precast blocks are pre-formed, cured and fired monolithic components made to drawings: tolerance ±2mm, covering castable, refractory castable and corundum materials. Factory-controlled quality with rapid on-site installation provides an integrated solution for complex furnaces. It is Henan Songrui's prefabrication solution for troughs, ladles, doors and cooler beams.
Precast suits repetitive, complex or site-constrained components; weigh schedule, quantity, transport and lifting. Design and installation schemes available.
Reserve expansion joints and seal joints to prevent gas penetration; avoid impact damage during lifting.
Henan Songrui New Refractory Materials Co., Ltd. (Xuanhua Town Industrial Park, Henan) is a 2024 Class A taxpayer and SRDI SME. For selection, quotation or prefabrication proposals, contact Manager Zheng (17513376789 / 17513376789@163.com).
Refractory precast blocks are factory-formed and fired for fast installation:
Factory quality and precision, pre-fired, fast installation—downtime cut by more than half.
Custom precasts made to drawing in any grade (high-alumina/corundum/mullite/SiC).
Typically 7-15 days including curing/firing; express available.

Cordierite-mullite kiln furniture (saggers, shelves, posts and beams) combines low thermal expansion with high refractoriness under load, offering excellent thermal shock resistance and long service life for ceramic, electronic ceramic and magnetic material kilns.
Slide gate plate is the core functional refractory of ladle and tundish slide gate systems, offering high strength, high density, excellent erosion and thermal shock resistance for precise molten steel flow control.
Ladle purge plug (corundum-spinel type) blowing argon at ladle bottom features high and stable permeability, high strength, excellent erosion and thermal shock resistance, homogenizing steel composition and removing inclusions in ladle refining.
Ladle shrouds and submerged entry nozzles are key functional refractories in continuous casting. They protect the steel stream against reoxidation and control mould flow. Alumina-carbon body with ZrO2 slag line resists slag, prevents clogging and sustains multi-heat sequences.
