Efficient production method of refractory bricks
The invention discloses an efficient production method of refractory bricks, and belongs to the technical field of refractory bricks. The method comprises the following steps: S1, material selecting:taking high bauxite clinker as a main material, and taking pyrophyllite fine powder, binding clay and paper pulp; and S2, mixing: putting the raw materials in the S1 into a crusher in proportion, thenadding the crushed raw materials into a mixing mill, and mixing for 25-40 minutes to obtain the pug. According to the invention, when the materials need to be manufactured on the same day, the pressure in the forming process reaches 140 MPa, the porosity of a semi-finished product is less than or equal to 23%, and the refractory brick is dried before being fired, so that the participated moisturein the semi-finished product is less than 2%, and the qualification rate of the semi-finished product can be ensured; and inspection can be conducted after the semi-finished products are formed, so that the semi-finished products can be recycled in time, it can be guaranteed that the defective product rate in the refractory brick machining process is low to a certain extent, high efficiency of the refractory brick machining process can be guaranteed to a certain extent, and raw material waste can be reduced.
本发明公开了一种耐火砖的高效生产方法，属于耐火砖技术领域，其包括以下步骤：S1、选料，采用高铝矾土熟料做主料，叶腊石细粉，结合粘土和纸浆；S2、混练，将S1中原料按比例投入粉碎机中，然后将粉碎后原料加入混炼机中混练25‑40min得到泥料。该一种耐火砖的高效生产方法，当日用料需要当日制作，成型过程的压力达到140MPa，半成品气孔率应≤23％，在耐火砖烧制之前会先进行干燥，保证半成品中参与水分小于2％，可以保证半成品的合格率，同时在半成品成型后会进行检验，可以及时对半成品进行回收再利用，可以在一定程度上保证耐火砖加工过程的残品率较低，可以在一定程度上保证耐火砖加工过程的高效，同时可以降低对原料的浪费。
