Magnesia-chrome brick for RH furnace vacuum chamber and preparation method
The invention relates to a magnesite-chrome brick for a vacuum chamber of an RH (Ruhrstahl Heraeus) furnace, the magnesite-chrome brick comprises an inner brick, two supporting strips are fixedly mounted at each of the top and the bottom of the inner brick, and an outer sleeve brick is arranged on the outer surface of the inner brick. According to the magnesite-chrome brick for the vacuum chamber of the RH furnace and the preparation method, the surface of the inner brick is sleeved with the outer sleeve brick, the inner brick is prepared by mixing coarse and fine raw materials and matching the mixture with the inorganic binding agent, the overall compactness is improved, the outer sleeve brick is prepared by matching aluminum oxide and high clay with the inorganic binding agent, and finally a double-layer brick body is prepared. The outer sleeve brick containing a large amount of aluminum oxide can enable the whole brick body to bear higher temperature, so that the product is greatly improved in thermal spalling resistance, meanwhile, the upper and lower surfaces of the inner brick are provided with the supporting strips, so that the thicknesses of the outer sleeve bricks on the upper and lower surfaces of the inner brick are consistent, the stability of the brick body is ensured, and finally, the service life of the brick body is prolonged. The side grooves and the surface grooves are formed in the outer sleeve brick, so that the whole brick body is more convenient to carry.
本发明涉及一种RH炉真空室用镁铬砖，包括内砖，所述内砖的顶部与底部均固定安装有数量为两个的支撑条，所述内砖的外表面设有外套砖。该RH炉真空室用镁铬砖及制备方法，在内砖表面套一层外套砖，其中，内砖采用粗细原料混合配合无机结合剂制备，整体致密性得到提升，而外套砖采用氧化铝、高黏土配合无机结合剂制备，最终制成双层砖体，相比现有的镁铬砖而言，含有大量氧化铝的外套砖可让整个砖体承受更高的温度，从而使得本产品在抗热剥落性上得到了大幅度提升，同时，在内砖上下两面均有支撑条，使得内砖上下两面的外套砖的厚度一致，保证了砖体的稳定性，最后，通过在外套砖上开设侧槽和面槽，使得整个砖体在搬运时更方便。
