In the configuration of high-temperature industrial furnace lining, not only castable integral furnace lining and refractory brick lining are needed, but also ceramic fiber cotton lining. They are used in different parts of the furnace lining according to the temperature conditions they can withstand. Rongsheng refractory material manufacturer has made a comparison between ceramic fiber … Read more
In order to solve the problem of slow hardening time of low-cement self-flowing castables in low-temperature environments such as winter, the effects of different types of accelerators on the setting time of low-cement self-flowing castables were studied. With the development of amorphous refractory castables, the proportion of castables used in heating furnace linings is increasing, … Read more
In steel rolling equipment, the heating furnace is a very important heating equipment. Plastic refractory for boiler. The quality of the heating furnace will have a great impact on the quantity and quality of steel rolling, and the refractory materials used in the heating furnace will largely affect the use of the heating furnace. Refractory … Read more
Burner, as the popular name of the combustion device on the industrial fuel furnace, can be understood as “fire nozzle”, and the burner brick is an indispensable and important part. The burner is generally equipped with a fuel inlet, an air inlet and an ejection hole, shouldering the important mission of distributing fuel and combustion … Read more
Under the erosion of flames and powder, the checker bricks in the regenerator are gradually melted into tumors, which blocks or even collapses the lattice body, reduces the heat storage capacity, and makes it difficult to discharge exhaust gas, affecting melting. At present, the regenerator checker bricks of large and medium-sized glass factories in China … Read more
The technical process of renovating the fire channel of a coke oven without removing the roof. The removal and reconstruction of the defect of one or more walls of one or more fire channels below the fire channel cover bricks is called fire channel digging and patching. Since the furnace head and fire channel partition … Read more
The construction process of glass melting furnace is generally to first lay the bottom flue and heat storage chamber, and then lay the bottom, wall and breast wall bricks of the large kiln. (1) Flue When laying the top layer of bricks at the bottom of the flue, it should be perpendicular to the airflow … Read more
Refractory materials for copper and nickel smelting. The main process of copper pyrometallurgy is very similar to that of nickel smelting, with only the following differences: the product of the copper smelting converter is crude copper, while the product of the nickel smelting converter is high-grade nickel matte (nickel matte with high nickel content); copper … Read more
Magnesium-aluminum dry vibrating materials can be used to line the melting grooves of power frequency induction furnaces used in foundry and nonferrous metal industries, and good results have been achieved. Dry vibrating materials and ramming materials are new types of amorphous refractory materials developed in the past 10 years, and are developed under the guidance … Read more
Phosphated high-alumina composite brick is a common type of new dry-process cement kiln brick, referred to as high-alumina phosphorus brick or phosphate brick. Phosphate brick products are high-alumina refractory products made of high-alumina bauxite clinker as the main raw material, phosphoric acid or aluminum phosphate as a binder, high-pressure molding, and heat treatment at 600°C. … Read more
