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
The aluminum smelting process mainly produces alumina, then electrolyzes the alumina into metallic aluminum and performs smelting, dehydrogenation and purification, and finally casts it into aluminum ingots. There are many types of kilns used for aluminum smelting, and the furnaces have lower operating temperatures and better use conditions. Generally, clay bricks and high-alumina bricks are … Read more
The fire baffle of brick kiln is an innovative product that can replace the traditional brick kiln hanging refractory bricks. It can improve the adjustment flexibility of the tunnel kiln and reduce the temperature difference in the kiln. In fact, this fire baffle is a rigid refractory material made of ceramic fiber, which belongs to … Read more
The life of the titanium slag electric furnace is one of the main factors affecting the production of titanium slag, especially because the production of titanium slag needs to complete the smelting process at a high temperature of 1600℃~1800℃. Since the titanium slag melt has extremely high chemical activity, it can react with almost all … Read more
What kind of material is used to paste acid-resistant bricks? Acid-resistant glue, epoxy resin glue? The material for pasting acid-resistant bricks needs to be based on the needs of the environment: If it is a general environment, then KP-1 type acid-resistant glue can be used, and the price is favorable. If it is in a … Read more
New environmentally friendly processes and reduced pollutant emissions are the new driving force in the steelmaking industry. Magnesia-chrome bricks fired at temperatures above 1700°C are used for permanent lining of ladles in the production of stainless steel, due to their high physical and mechanical properties and dimensional stability. Tempered refractory bricks use a special binder … Read more
