Embodiment Construction
[0019] In this technical solution:
[0020] The present invention proposes a kind of production technique that utilizes cordierite to process and produce refractory brick, and described production technique comprises the following steps:
[0021] i. Raw material mixing, raw material supply, and automatic weighing: kaolin, talc, mullite, and zircon are separately pulverized by a ball mill, and fully stirred by a mixer respectively, and the kaolin powder, talc powder, and mullite are mixed by a conveyor belt The stone powder and zircon are directly fed into the weighing machine for weighing. The production of refractory bricks by cordierite is calculated on the basis of 1000g of raw materials, kaolin powder is 100.00-120.00g, talcum powder is 350.00-400.00g, mullite powder is 160.00- 200.00g, 40.00-60.00g of zircon, and weigh the rest 50.00-100.00g of binder, 140.00-280.00g of purified water, to be prepared;
[0022] ii. Mixing and stirring, press pressing: Put the prepared kao...

Abstract
The invention belongs to the technical field of refractory brick production, and particularly relates to a production process for producing refractory bricks by utilizing cordierite processing, whichsequentially comprises the following steps of: stirring raw materials, supplying the raw materials, automatically weighing, mixing and stirring, pressing by a pressing machine, carrying green bricks,inspecting the green bricks, tapping the green bricks, firing in a rotary kiln, cooling finished bricks and inspecting the finished bricks. The calcined kaolin is used for partially replacing raw clay, so that the shrinkage resistance and the thermal shock resistance of the refractory brick can be improved, zirconite powder can be decomposed into zirconium oxide in the firing process, so that thethermal shock stability of the refractory brick is improved, and the toughening effect is achieved, the kaolin powder, the talcum powder, the mullite powder and the zirconite are reasonably proportioned, so that the refractory brick has a stable structure, an ordered production process and a reasonable proportion are adopted, therefore, the effects of high production efficiency, uniform specification, stable proportioning structure and good quality are achieved.
Description
technical field [0001] The invention belongs to the technical field of refractory brick production, and in particular relates to a production process for producing refractory bricks by processing cordierite. Background technique [0002] The production of traditional refractory bricks is inefficient and the production environment is poor. Due to the manual operation, it is easy to cause low quality refractory bricks and different specifications, and the refractory bricks are generally synthetic cordierite. Both the ratio and the firing method have an impact on the overall quality of refractory bricks. Therefore, it is urgent to develop a production process that uses cordierite to process refractory bricks with high production efficiency, uniform specifications, stable proportioning structure, and good quality. Contents of the invention [0003] (1) Technical problems to be solved [0004] In order to overcome the low efficiency and poor production environment of the tradi...
