An induction melting furnace lining repairing material, characterized in that it is made of the following weight percentages of raw materials: waste glass powder
1% -7%, fused quartz 25% -55%, fused silica fine powder 15% -35%, chromium oxide fine powder 17.5% -27.5%, zirconia fine powder
Powder 5% -10%, boric anhydride 0.5% -1.5%. The fused quartz fineness is 20-325 mesh. The method for using the furnace lining repair material of the induction melting furnace is characterized in that, in the induction melting furnace, at a temperature of 1000-1200 ° C, a conventional spray gun is sprayed on the furnace wall to repair the furnace lining.
The basic principle and idea are: use the characteristics of glass powder medium temperature (450-600 degrees Celsius) sintering, with boric anhydride medium temperature (450 degrees Celsius) sintering performance, under the conditions of induction melting furnace temperature above 1000 degrees Celsius, spray coating on the furnace lining wall quickly The high-temperature performance and thermal shock stability of fused quartz are better than that of furnace lining quartz sand, which can be sintered into a ceramic layer during the smelting process, which meets the requirements for the lining of molten iron or molten steel working layers; zirconia and chromium oxide have strong resistance to slag erosion Performance, also has excellent high temperature performance, can prevent slag erosion of the furnace lining and molten iron / molten steel penetration of the furnace lining. Change spraying and refilling,
It maintains sufficient thickness of the working layer of the furnace lining, prolongs the furnace lining life of the induction melting furnace, and achieves the effect of long age.
detailed description
1) Proportion table of repair materials (unit: parts by weight)
2) The configuration of pristine materials: take all kinds of raw materials for implementation 1, 2 or 3, and dry mix them evenly.
3) How to use repairing materials: In an induction melting furnace at a temperature of 1000-12000C, use a conventional spray gun to the furnace wall
Spray on and repair the furnace lining.
