Aluminum Oxide 30 Or 40 Grit Suppliers South Korea

The main varieties are: refractory concrete, refractory plastic, refractory projective material, refractory spray coating and refractory coating material(60 grit aluminum oxide). Amorphous refractories will play an important role in prolonging lining life, increasing equipment operation rate, reducing labor intensity and simplifying refractory production process(80 grit aluminum oxide). Therefore, the amorphous refractories have a bright future, which are still in use after more than 4 years of operation.

In order to improve the service life of furnaces, spray repair, press in repair and bandage repair are widely used in many countries(100 grit aluminum oxide blast media). As we all know, in the early 1960s, Japan's Sanrong Iron Industry Co., Ltd. used refractory castable as lining on blast furnace for 2 years and 8 months, which reached the specified iron production and the residual lining was in good condition(fine grit aluminum oxide). The refractory concrete pouring and prefabricated components are used in the waist and above of 355m blast furnace.


In the past 10 years, the development of amorphous refractories at home and abroad is very rapid, and the varieties are increasing. Only some carbon deposition caused by CO was found(150 grit aluminum oxide); In China, all refractory concrete prefabricated components and cast-in-situ vibration are used on 19m and 21m small blast furnaces, which are still in use after more than 3 years of operation(180 grit aluminum oxide). In the process of gunning, it is generally carried out after the wind is shut down or the old village is removed.


Russia, China and other countries have also carried out gunning for the inner villages of blast furnace walls(brown fused alumina). According to the experience of blast furnace production in various countries, the high alumina clinker silicon carbide graphite ramming material (or castable) should be gradually used in the alignment of large-scale tapping ditch(220 grit aluminum oxide blast media). In addition, the blast furnace throat and the parts below the protection plate, the direct blowing temporary and the gas lifting pipe can be repaired by spraying.


The adhesion rate of the fire-resistant coating is about 70%(180 grit aluminum oxide blasting media). Cut the test block from the gunning layer, and the flexural strength is 3.5 ~ 4.3mpa after being burned at 1200 ℃(brown aluminum oxide). The inner village of blast furnace is a weak link in production, especially in the lower part of the bosh and shaft, which is often forced to stop large and medium-sized repair due to premature damage(240 grit aluminum oxide). The lining of dozens of blast furnaces in Britain was repaired by spraying when it was damaged.


Generally, high alumina cement or silicate alumina refractory gunning coating with water glass is adopted for semi dry operation(brown aluminium oxide). When the lining of American blast furnace wall is damaged, it is usually repaired by spraying. In general, when the inner seal of the furnace wall is damaged, the aluminum silicate material is also used for repairing(70 grit aluminum oxide blast media). Two new gunning technologies have been developed recently, and good results have been obtained.


After the gunning layer has been used for 3 months, there are still residual linings(220 grit aluminum oxide); Sumitomo Metal Company uses a dry gunning machine to Gunn the lining of the blast furnace wall, which is characterized by that the nozzle is made of refractory materials and inserted into the furnace from the original inspection port, which can be operated without wind(120 grit aluminum oxide harbor freight). The gunning can extend the long life by 3-6 months, and the cost is only one tenth of that of the old method.
