摘要： A refractory which is prepared by forming a refractory material composition comprising a refractory material comprising graphite particles having an average particle diameter of 500 nm or less or a refractory material comprising graphite particles obtained by graphitizing carbon black and a refractory aggregate; or a refractory which is prepared by forming a refractory material composition comprising a carbonaceous particles (A) having a DBP absorption (x) of 80 ml/100 g or more selected from carbon black and graphite particles obtained by graphitizing carbon black, a carbonaceous particles (B) having a DBP absorption (x) of less than 80 ml/100 g selected from carbon black and graphite particles obtained by graphitizing carbon black, and a refractory aggregate. The refractory provides a carbon-containing refractory, in particular, the one having a reduced content of carbon, which is excellent in the resistance to corrosion, oxidation and thermal shock.

摘要： Carbon-bond forming unshaped refractories excellent in workability and service life by solving the problems of the refractories used for the working or repair of various molten metal containers, such as bursting, lack of volume stability, low adhesion strength and low hot strength. An example of the refractories comprises 100 parts by weight of refractory material and 1-30 parts by weight of pitch having the fixed carbon content of 65-90 wt.% and the softening point of 250-350 °C, and another example thereof further contains 0.01-0.5 part by weight of carbon fibers. These refractories are applicable as any of gunning refractories, casting materials of particularly water-base type, baking materials, mortars, and stamping materials. The refractory materials usable herein include all of the basic, neutral and acidic materials. When the gunning refractories also contain high-molecular-weight thermosetting phenol resins, the effects of the refractories are further improved.

摘要： The object of the invention is to provide monolithic refractory capable of solving the drawbacks of the conventional monolithic refractories such as rupture, lack of low shrinkage, low bonding strength, low hot strength and having both superior strength and superior applicability.
The present invention provides monolithic refractory comprising 1 to 30 weight parts of pitch having 65 to 90 wt% of fixed carbon and a softening point of 250 to 350 °C to form carbon bond, relative to 100 weight parts of refractory material so as to form carbon bond.
The present invention also provides the monolithic refractory added with 0.01 to 0.5 weight part of carbon fiber. These may be used as any type of monolithic refractory such as gunning material, casting material, in particular, aqueous type casting material, burning type hot repairing mix, mortar, stamping material and any basic, neutral or acid refractory material may be used.
In the case of gunning material, if heat-hardening type type phenol resin having a high molecular weight is added to the above, the effect may be further enhanced.摘要翻译： 本发明的目的是提供能够解决传统的单片耐火材料的缺点的单片耐火材料，例如断裂，低收缩性，低粘结强度，低热强度，并具有优异的强度和优异的适用性。 本发明提供了相对于100重量份的耐火材料，包含1至30重量份的沥青，具有65至90重量％的固定碳和软化点为250至350℃以形成碳键，从而形成 碳键。 本发明还提供了加入0.01至0.5重量份碳纤维的整体耐火材料。 这些可以用作任何类型的整体耐火材料，例如喷枪材料，铸造材料，特别是水性铸造材料，燃烧型热修复混合物，砂浆，冲压材料和任何碱性，中性或酸性耐火材料。 在喷涂材料的情况下，如果加入高分子量的热硬化型酚醛树脂，则可以进一步提高效果。
