Abstract
The invention provides a method for manufacturing refractory clay for constructing refractory bricks of flame path walls of baking furnaces. Raw materials for manufacturing the refractory clay are obtained from mixing four or more than four of bauxite chamotte I, bauxite chamotte II, bauxite chamotte III, mullite chamotte, alumina powder and high-quality porcellanite, and adding mixture of two or more than two of sodium carboxymethylcellulose, sodium tripolyphosphate, sodium hexametaphosphate and yellow dextrin, wherein the bauxite chamotte I, the bauxite chamotte II and the bauxite chamotte III are different in finenesses and Al2O3 contents. The method includes the steps of weighing, stirring, sealing and packing the raw material mixture in bags; when in construction of the refractory bricks on the construction site, adding the mixture into a slurry mixer, weighing and adding 33-38 weight parts of clean tap water into every 100 weight parts of mixture, and fully stirring for at least 10 minutes. Thickness of the refractory clay is determined for the convenience of utilization. The method for manufacturing the refractory clay for constructing the refractory bricks of the flame path walls of the baking furnaces is simple in process and low in cost, the refractory clay manufactured is high in bonding strength and strong in fire retardance under the conditions of low temperature, middle temperature and high temperature, and the flame path walls constructed are firm, durable and long in service life.
