Iron Brick of Kiln Head Is Important for Rotary Kiln
Posted Nov 05 2012 1:12am
The iron brick plays the protection role for the kiln head and the liner of the kiln head of the rotary kiln. At the same time, the iron brick should bear the downward tilting force of the shaft of the liner caused by the incline of the kiln body. The iron brick of the kiln end in this part should have both the resistance, high temperature resistance and abrasion resistance. Over the years, the iron bricks are made of the stainless board and the heat-resistant steel. The service life is only 3 months to 6 months, which seriously affect the operation cycle of the clinker kiln and the economic efficiency of the enterprises. How to seek and develop a kind of iron brick for the kiln head which is suitable for the operating conditions of the equipment has become a very important topic at home and abroad. In terms of the domestic high-temperature materials, we have the materials with the standard which can adapt to the antioxidant and heat resistant steel above 1100 ℃ heat-resistant steel, heat resistant steel above 500 ° C and the aeronautical materials, such as the nickel base alloy and the iron-base alloy. However, there is no special standard for the high-temperature resistant materials which can both have the high-temperature erosion, wear resistance and wear-resistant material. The study and development in this area is also small. Henan Hongxing is a professional mining machinery manufacturer. Henan Hongxing Mining Machinery has wide study and application in terms of the high-temperature materials. Since the promotion and use of the foreign materials is very inconvenient, Henan Hongxing Mining Machinery has done a lot of work on the development and research on the high-temperature materials depending on many years’ experience. The technology developed and researched by Henan Hongxing Mining Machinery has applied to the research project. From the actual use of the iron bricks for the kiln head of the rotary kiln, the high-temperature materials have reach the target of the operation cycle.
