Abstract

The invention relates to a main spare part lined in a tower vessel apparatus, in particular to a toughened porzite seamless arc porcelain-lined brick and a manufacturing method thereof. The brick comprises porzite, bauxite, zirconite, zirconia, kaoline and feldspar. The manufacturing process comprises the following steps: combination of raw materials and subsidiary ingredients, ball milling, iron removing, sieving, spray particle drying, additive, mustiness, particle gradation, isostatic moulding, grading, fettling, rinsing, baking, checking, packaging and warehousing. The toughened porzite seamless arc porcelain-lined brick brings the excellent characteristics of porcelain such as ideal abrasion resistance, high rigidity, ideal acid and alkali resistance, no oxidation, high temperature resistance, light specific gravity and high compressive strength into full play, and also overcomes the fragile disadvantage of porcelain by means of the special crystal phase structure of zirconia-toughened porzite; therefore, the service life of the brick is longer than those of lining materials including ordinary porcelain, granite and marble tower adopted by the prior art, which ensures that the brick has strong market competitiveness and durability.

Description

technical field [0001] The invention relates to a main accessory of the inner lining of a tower container equipment device, a toughened mullite seamless arc-shaped porcelain lining brick and a manufacturing method thereof. Background technique [0002] Over the years, the original technology of ordinary ceramics, granite, marble, etc. has been used as special materials for the lining of tower equipment. Due to the high proportion of this product, it is easy to oxidize and corrode, easy to drop, large wear, large energy consumption, high replacement frequency, and long service life. Short, high cost, etc. cannot meet the equipment and product quality requirements. Toughened mullite seamless arc-shaped porcelain lining bricks are suitable for gas-liquid mass transfer tower container equipment that is indispensable in oil refining, chemical, fertilizer, coking, metallurgy, smelting, spices, pharmaceuticals and other industries. However, the general-purpose mullite seamless por...
