In April 29, 2017, Baosteel Group Xinjiang Bayi Steel 2000m³ COREX direct reduction furnace and B#2500m³ blast furnace gas leakage out of iron notch project started installed by Allied Rongda. The main installation site was between the shell of the hearth and the cooling wall, Apply with the pressing installation, through the way of grouting to manage the gas leakage effective, iron slag splashing, lay a good foundation for the safe production of the blast furnace.
May 3rd, COREX direct reduction furnace ( Bagang said Europe Yelu ) pressed into the hearth successfully completed, effective control of the hearth gas serious leakage phenomenon, and realize the goal. This is an important practice of our company press in the non-blast furnace to effectively alleviate the gas leakage, will has the important guiding significanc when our company face to the similar smelting furnace plugging gas in the future.
Allied Rongda has the series of relining products with pressure in the blast furnace, mainly used for blast furnace lining grouting, hot blast stove, heat pipe and other smelting equipment lining, its main features: has good adhesion, expansibility, installation of good liquidity, low early strength, from low temperature to high temperature with high strength, the organization of installation body has a dense, and canbe storage.
There are four kinds of products to solve the needs of different parts lining respectively. RY-65 for cooling wall of blast furnace refractory lining repair made; RDT-55 for blast furnace tuyere and cooling plate of the press in; RYT-1 and RYT-2 for pressing maintenance of blast furnace hearth and the taphole; Pressing hard materials RAP for the pressure into the lining maintenance of shaft, belly and bosh.
Allied Rongda blast furnace lining pressing technology has been widely used in domestic blast furnace, with the accumulation of years of experience, with professional technology and engineering team, according to the existing problems of blast furnace and the demand of the customer, using appropriate technology, appropriate equipment and suitable materials, and ultimately solve customer needs and problems.
