技术领域
本发明涉及的是连铸耐火材料技术领域，具体的说是一种连铸用无硅无碳刚玉质水口塞棒制品及其制备工艺。
背景技术
随着炼钢工艺的技术发展，及其高强度、高性能的技术要求，对连铸过程中所用耐火材料也提出了更高的要求，不仅要求连铸用功能耐火材料使用寿命高，而且要求对钢不能造成二次污染。
目前连铸用功能水口塞棒的主要原料是鳞片石墨、刚玉、熔融石英、锆莫来石等，虽然鳞片石墨是很好的耐火原料，不仅有很好的导电导热性，而且具有很好的抗渣性以及钢水的抗侵蚀性能，但是由于鳞片石墨的主要化学成分是碳元素，对低碳优质钢的钢水造成一定程度的增碳；熔融石英虽然也是一种优质耐火原料，不仅具有很好的抗钢水、钢渣侵蚀性，而且热膨胀特别低，但炼优质合金钢时，由于钢水内合金锰元素易生成硅酸锰，严重污染钢水，致使钢材的性能质量降低。
发明内容
本发明的目的在于针对现有技术的缺陷和不足，提供了一种连铸用无硅无碳刚玉质水口塞棒制品及其制备工艺，有效解决连铸耐火原料在高温下使用出现的热膨胀高的问题，具有很好的使用性能。

一种连铸用无硅无碳刚玉质水口塞棒制品，按照材料的重量百分比，包含60～98％刚玉、0.5～20％轻烧氧化铝微粉、1～10％软质粘土。
作为本发明的进一步改善，它还包含结合剂，所述结合剂由磷酸、磷酸铝、氯化铝、氯化镁、硫酸铝、树脂、硅酸钠中的一种或者几种组成。
一种连铸用无硅无碳刚玉质水口塞棒制品的制备工艺，步骤如下：根据配方比例，取刚玉颗粒、轻烧氧化铝微粉以及粘合剂均匀混合后，依次成型，并进行干燥处理，干燥处理后进行热处理，热处理后在所获得的产品表面涂覆防透气抗侵蚀涂层，即可得到水口塞棒制品。
作为本发明的进一步改善，所述成型时采用的是等静压力机、油压机、或者摩擦压力机进行成型和干燥处理。
作为本发明的进一步改善，所述干燥处理后先进行了车床加工，在进行热处理，所述热处理的温度为200～800℃，常温～200℃，24小时，保温4小时。
作为本发明的进一步改善，所述防透气抗侵蚀涂层材料为轻烧氧化铝微粉、碳化硼、氧化铬、电熔氧化锆、碳化硅等水玻璃、磷酸铝几种。
本发明的有益效果为：有效解决连铸耐火材料在高温下使用出现的热膨胀高的问题，具有很好的使用性能和高气孔,采用中低温的热处理方法，节约了能源且有可靠的安全性，为社会创造了大量经济效益和社会效益。
