EAF Refractories

Neutral ramming mass is able to resist penetration & protrusion of cracks & pores into the refraction lining, thus providing safety from penetration of molten steel towards the heat sensitive crucible & neutral ramming mass also ensures easy removal while replacing the lining. With a specific ability of sintering only on the surface, that is in contact with the molten steel. Neutral ramming mass Neutral ramming mass has a series of advantages such as erosion resistance, strong stability, non-cracking, strong operability and high fire resistance.

Refractory brick The use of kilns is inseparable from refractory bricks, but if the details of refractory bricks are not properly handled during the masonry process, it will bring a lot of trouble to the later use. Therefore, when building refractory bricks, pay attention to the angle and also Pay attention to the location, as far as possible, choose refractory bricks with good refractory material performance, and there will be no thermal expansion and contraction and chemical reactions during use, as described in detail below. How to choose refractory brick: 1. Resist the effect of high temperature heat load, not softening or melting. Refractory bricks are required to have a fairly high degree of refractoriness. 2. Resist the effect of high temperature heat load, the volume does not shrink and only uniform expansion. It is required that the material has high volume stability, the residual shrinkage and residual expansion should be small, without crystal form transformation and
