Problems solved by technology

[0002] During the production process of traditional smelting furnaces, there will be charge splashing, which not only causes damage to the working environment, but also wastes resources. The slag of traditional smelting furnaces has a strong erosion of the furnace wall, and the capacity of charge is relatively small. The single output Not high, increasing production difficulty and cost

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...

Abstract

The invention discloses a bottom dropping method of a three-ton smelting furnace. The method comprises the following steps of: A, proportioning; B, building the furnace, (1) before bedding of the furnace, examining whether induction coil cement falls, repairing the fallen part and necessarily drying after repair, (2) ramming a furnace bottom, (3) ramming a furnace body and (4) ramming a furnace collar; and C, roasting the furnace, wherein the furnace roasting time is 10-18 hours. The smelting furnace produced by the invention is solid and stable and has high resistance and superior integral quality, the erosion to the furnace wall by slag is reduced, the capacity of the charge is large, one-time yield is high, and the production difficulty and the production cost are reduced.

Description

technical field [0001] The invention mainly relates to a method for making a 3-ton smelting furnace, which belongs to the field of manufacturing. Background technique [0002] During the production process of traditional smelting furnaces, there will be charge splashing, which not only causes damage to the working environment, but also wastes resources. The slag of traditional smelting furnaces has a strong erosion of the furnace wall, and the capacity of charge is relatively small. The single output It is not high, which increases the difficulty and cost of production. Contents of the invention [0003] The object of the invention is to provide a method for making a 3-ton smelting furnace in order to make up for the defects of the prior art. [0004] The present invention is achieved through the following technical solutions: [0005] A method for making a 3-ton smelting furnace, comprising the following steps: [0006] A: Ingredients [0007] (1) Mix 45-55 kg of quar...
