        球狀瀝青屬于高溫煤瀝青的一種，是用煤焦油瀝青經(jīng)加熱溶解、噴淋、冷卻成型工藝而制成。瀝青分為煤焦油瀝青和石油瀝青兩大類，耐火材料用瀝青結(jié)合劑主要是煤焦油瀝青。將試驗(yàn)用原料瀝青加入瀝青溶解釜中加熱溶解，同時(shí)接通電熱圈電源，液態(tài)瀝青即從噴嘴噴出，由空氣霧化成細(xì)小顆粒，瀝青顆粒在冷卻塔內(nèi)用空氣自然冷卻成半成品，由冷卻塔底送入三次元振動(dòng)篩分過(guò)濾機(jī)分級(jí)，即得符合要求的球狀瀝青產(chǎn)品。

       球狀瀝青具有固定碳，甲苯不溶物，樹脂含量高，灰分低等特點(diǎn)；軟化點(diǎn)110℃，結(jié)焦值58%，灰分0.3%，揮發(fā)分57% ,碳45%。球狀瀝青產(chǎn)品有：高溫瀝青，高溫球狀瀝青，超高溫瀝青(軟化點(diǎn) > 180度)，改質(zhì)瀝青、軟瀝青等系列煤瀝青產(chǎn)品 ，用于生產(chǎn)鐵溝料，搗打料，補(bǔ)爐料，炮泥，以及鎂碳磚，以及其它耐火材料等。

球狀瀝青用途

       球狀瀝青用于生產(chǎn)鐵溝料，搗打料，補(bǔ)爐料，炮泥，以及鎂碳磚，以及其它耐火材料；廣泛用于高爐鐵鉤料、高爐噴補(bǔ)料、搗打料及澆注料和不定型耐火材料，碳素材料的添加劑，可起到粘結(jié)和增碳作用，調(diào)高產(chǎn)品的耐高溫，抗沖刷的能力。

Introduction of spherical asphalt

Ball belongs to a kind of high temperature coal tar, asphalt is dissolved in coal tar pitch by heating, spraying, cooling molding process and made. Divided into two major categories of coal tar, asphalt and petroleum asphalt, asphalt refractory with asphalt binder are mainly coal tar pitch. Dissolved the test materials asphalt adding asphalt heating to dissolve in the kettle. Turn on the electric heating circle power at the same time, the liquid asphalt from the nozzle, namely by the air atomization into tiny particles. Asphalt particles in the cooling tower with natural cooling air into semi-finished products, from the bottom of the cooling tower into three dimensional vibrating screen points grade of filter, a quick conform to the requirements of the spherical asphalt products.Spherical asphalt with fixed carbon, toluene insolubles, high resin content, low ash content. Softening point 110 ℃, coking value 58%, ash 0.3%, volatile 57%, 45% carbon.

Spherical asphalt products are: high temperature of asphalt, high temperature ball asphalt, ultra high temperature asphalt softening point (> 180 degree), modified asphalt, soft series, such as coal tar products and recarburizer products, coal tar products, used in the production of iron ditch, ramming material, charging and stemming, and magnesia carbon brick, and other refractory materials.

Spherical asphalt use

Spherical asphalt used in the production of iron ditch, ramming material, charging and stemming, and magnesia carbon brick, and other refractory materials. Is widely used in the blast furnace iron hook, blast furnace gunning material, ramming and castable and not stereotypes refractories, carbon materials, additives, bonding and a carbon effect, raise the product high temperature resistance, resistance to scour capability.
