For electric arc furnace, the key point effecting service life is working layer. Working layer would touch melton steel directly, where is of high thermal load, heavy chemical mechanical erosion. So high quality refractories should be adapted in working layer.

Regular lining method for EAF working layer is namely sintering, vibrating and brick-construction. For brick-construction method, asphalt binder magnesia brick is widely used. For sintering and vibrating method, magnesia sand with tar a

The covering agent mentioned in the title is a kind of refractories. It is a particulate carbonized rice husk covering agent, which includes 44-52% bran shell powder, 29-33% vermiculite, 9-11% cement clinker and 7.8-8.5% cassava flour, also includes 2.5-3.5% expanded graphite. It’s characterized to improve the thermal expansion coefficient of the covering agent.

The particulate carbonized rice husk covering agent is in ball shape, particle size is 3mm-10mm, to ensure the spreadability. This

Ladle shroud, also named as long nozzle, as a refractory product it is used as a connection nozzle between Ladle and Tundish. In order to keep the molten liquid from being oxidized and splattered when it flows from ladle to tundish, a shroud is needed to be installed underneath the ladle. One side is connected with lower nozzle, and the other side inserts into the tundish for casting in a sealed condition.

Ladle shroud function is stated as follows: Protect the molten liquid from oxidized, wh

Monoblock stopper?is formed by static pressing. The shape and size depend on the capacity of tundish, the height of steel surface, horn shape of tundish nozzle and aperture size. Monoblock stopper head is monoblock stopper hollow with argon blowing hole and air plug. The key point is fixing method. One type is fixed by metal pin. The other type is fixed by screw thread.

The main function of monoblock stopper is used for on-off of tundish. It can not only control the flow of the molten steel
