Full-range refractory solutions for blast furnaces, hot blast stoves, iron runners, converters, EAFs and ladles.
Iron & steel is the largest downstream consumer of refractories. Henan Songrui New Refractory Materials Co., Ltd. supplies integrated packages — from high-alumina and corundum-SiC castables to precast trough channels and MgO-C bricks — for blast furnaces, hot blast stoves, casthouse runners, converters, EAFs and ladles. For main-trough washing, slag-line attack and ladle thermal cycling, the company recommends grade, thickness and lining design per service condition, with batch test reports.

Industry Kilns
Typical kilns in this industry — click each to see its specific problems and solutions
Blast Furnace1 problems
The blast furnace is the core ironmaking unit; linings face 1100–1500°C heat, slag/metal attack and alkali damage, with long campaigns relying on hearth ceramic cups and bosh cooling staves.
View Problems & Solutions →Hot Metal Ladle1 problems
The hot metal ladle transports and holds molten iron; its bottom suffers impact and its slag line suffers slag attack, making it one of the most frequently relined refractory zones.
View Problems & Solutions →Hot Blast Stove1 problems
The hot blast stove preheats blast air to 1150–1300°C via checker bricks; checker service life and hot-blast main lining integrity determine achievable wind temperatures.
View Problems & Solutions →Iron Runner1 problems
The iron runner guides blast-furnace hot metal to ladles; its slag line endures alternating metal/slag scouring, with Al2O3-SiC-C castable throughput being the key metric.
