本发明涉及预制件生产技术领域,尤其涉及一种加入高温粘接剂、煨法烧结的新型脱硫枪生产方法。
背景技术
现有的脱硫枪的使用寿命严重不够,导致全国钢铁脱硫消耗的脱硫枪材料成本为0.6元/吨以上,而日本生产钢铁脱硫消耗的脱硫枪材料成本为0.4元/吨左右,说明国内现有的技术生产的脱硫枪使用寿命明显落后于国际先进水平。改进脱硫枪生产工艺技术,提高脱硫枪炉盖等预制件的使用寿命成为耐火材料生产领域的一项迫切需要。调查发现,现有企业生产的预制件生产工艺采用浇注法,以拉法基水泥加水做为粘接剂,在模套内凝结塑造成型,因为水凝物的存在,无法用外力时原料密实,加上焙烧时,内部水份从毛细管中排除,预制件的直径较大,一部分水份受热焙烧无法及时从毛细管有序排出,产生较大的应力,导致脱硫枪表面出炉前出现很多横向微裂纹,待冷却后,枪体收缩,微裂纹消失。产品验收是无法检查出来的。正是这些微裂纹的存在,当脱硫枪没入铁水使用时,枪体受热膨胀,微裂纹又出现,多次使用后形成裂缝,铁水渗入裂缝,两者膨胀系数不同,加速裂缝的扩大,从脱硫枪修补时裂口来看,修补脱硫枪只是对裂缝的铁水渗入的入口堵住,但内部残留铁水降低渗透速度,断了其后援,使用寿命能少量延长,但无法改变其总体使用寿命短的问题。使用水泥加水做粘接剂,可塑性好,工艺简单,投资少,技术含量低,门槛低等优势。但水泥中游离钙的存在,加水生成溶胶物,熔点低,耐冲刷能力差,即使没有早期裂纹出现,使用寿命也低。脱硫枪需要来回抽出和***铁水,枪体反复加热和冷却,需要枪体材料抗热震性能高;枪体结构密实,抗渗透性能强确保脱硫枪耐冲刷。
该高温粘接剂具有线变化率小、高温体变化率不明显、高温强度好、密实度高、防渗漏能力强的铝酸钙与尖晶石混合质特种耐火原料。高温粘接剂因有钙的成分存在,高温(>1700℃)条件下,钙原子呈游离态,活性高,极易与铁水中的二氧化硅迅速反应,生成熔点仅为1350℃左右的低熔物,所以产品的耐冲刷性能差,产品使用寿命低。该专利方法就避开用水泥和水做结合剂,改用树脂做结合剂,高温时煨法焙烧时,型材内不会产生大量气体排除使产品出现较大的热应力,加上原料体积变化小,避免前期微裂纹的出现。
高温粘接剂的耐火度高(>1800℃),1450℃左右的铁水和<1500℃的半钢都无法破坏该型材的结构,使脱硫枪、炉盖等耐火挤压件在没入熔体内使用时,不会出现裂纹。原料的抗热震性能好,加上高温煨法焙烧工艺,挤压件内部结构焙烧密实且稳定,未脱硫的铁水和半钢温度条件下,挤压成型的预制件不会产生裂纹。
因为前后没有裂纹出现,半钢低氧化性环境,在此温度范围内脱硫剂和铁水都不会对枪体产生大量熔蚀,由外而内的微量、缓慢熔蚀使脱硫枪和炉盖等耐材产品使用寿命成倍延长,产品售价高,但钢铁生产脱硫工序吨钢消耗的脱硫枪材料成本达到国际先进水平,及0.4元/吨左右。
本发明提出一种加入高温粘接剂、煨法烧结的新型脱硫枪生产方法。
