Toughened porzite seamless arc porcelain-lined brick

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
