Embodiment 1
[0026] A method for making a 3-ton smelting furnace, comprising the following steps:
[0027] A: Ingredients
[0028] (1) Mix 50 kg of quartz sand with a size of 1-3 mm and 30 kg of borax, and rub it repeatedly by hand until the borax is completely powdered;
[0029] (2) Mix 200kg of quartz sand with a specification of 1-3mm and 100kg of quartz sand with a specification of 3-5mm and mix them repeatedly with a shovel until uniform, sprinkle the mixture in step (1), and then mix for 5- 8 times until uniform;
[0030] (3) Mix water glass, modified attapulgite and clear water in a weight ratio of 3:2:2, take 3 kg of the mixture in step (2), stir repeatedly, add 450 kg of quartz powder and then Stir repeatedly until evenly mixed, and hold the mixed mixture tightly with your hands to form a ball;
[0031] The preparation method of the modified attapulgite is as follows: the attapulgite is soaked with 15% hydrochloric acid for 4 hours, washed with deionized water, then soaked with...
