Tundish dry ramming mix material. Dry Ramming Material is an unshaped refractory material formed by vibration method without adding water or liquid binder. Under the action of vibration, the material can form a dense and uniform whole. When heated, thermosetting binders or ceramic sintering agents are used to create strength. Dry vibrating materials are composed … Read more
At present, the working layer of high-power and ultra-high-power electric furnaces is generally constructed with magnesia dry ramming material. The refractory materials used in the working layer are in direct contact with molten steel and slag. Directly withstand high-temperature heat load and erosion of molten slag, erosion of molten steel, mechanical impact of scrap steel, … Read more
Dry ramming materials can be constructed by direct vibration or direct vibration. The direct ramming method is to use a vibrator to directly ram the refractory material. After fully vibrating a layer of refractory material with a rammer, rake its surface, then fill it with a new layer of material, and then fully vibrate it … Read more

As the name suggests, low-cement castables are castables with low cement content, low cement dosage, and small calcium content. The lower the calcium content, the lower the pores and the stronger the erosion resistance. Low-cement castables are divided into low-cement castables such as aluminum silicate, mullite, corundum, magnesia-aluminum, fine stone, carbon, and silicon carbide. Low … Read more
