Embodiment 1
[0019] A lubricant for semi-continuous casting of brass, which consists of the following materials and parts by weight: 75 parts of dehydrated borax and 25 parts of dehydrated industrial salt.
[0020] The preparation method of above-mentioned semi-continuous casting brass lubricant is:
[0021] (a) Put 500kg of borax into an iron drum and put it into a well-type resistance furnace to heat up to 500°C, keep it warm and bake for 2 hours, continue to bake for 2 hours after power off, and take it out when the furnace temperature drops to 30°C to obtain dehydrated Borax, use a pulverizer to crush it into a powder with a particle diameter of 0.1 to 0.15 mm to obtain dehydrated borax powder;
[0022] (b) Put 100kg of industrial salt into an iron drum and put it into a well-type furnace to raise the temperature to 300°C, keep it warm and bake for 2 hours, continue to bake for 2 hours after the power is turned off, and take it out when the furnace temperature drops to 30°C to obtain d...
Embodiment 2
[0026] A lubricant for semi-continuous casting of brass, which consists of the following materials and parts by weight: 82 parts of dehydrated borax and 18 parts of dehydrated industrial salt.
[0027] The preparation method of above-mentioned semi-continuous casting brass lubricant is:
[0028] (a) Put 500kg of borax into an iron drum and put it into a well-type resistance furnace to raise the temperature to 600°C, keep it warm and bake for 1 hour, continue to bake for 4 hours after the power is turned off, and take it out when the furnace temperature drops to 50°C to obtain dehydrated Borax, use a pulverizer to crush it into a powder with a particle diameter of 0.1 to 0.15 mm to obtain dehydrated borax powder;
[0029] (b) Put 100kg of industrial salt into an iron drum and put it into a well-type furnace to heat up to 350°C, heat it up and bake for 1 hour, continue to bake for 4 hours after the power is turned off, and take it out when the furnace temperature drops to 50°C t...
Embodiment 3
[0033] A lubricant for semi-continuous casting of brass, which consists of the following materials and parts by weight: 88 parts of dehydrated borax and 12 parts of dehydrated industrial salt.
[0034] The preparation method of above-mentioned semi-continuous casting brass lubricant is:
[0035] (a) Put 500kg of borax into an iron bucket and put it into a well-type electric resistance furnace to raise the temperature to 550°C, heat and bake for 1.5 hours, continue to bake for 6 hours after the power is turned off, and take it out when the furnace temperature drops to 80°C to obtain dehydrated Borax, use a pulverizer to crush it into a powder with a particle diameter of 0.1 to 0.15 mm to obtain dehydrated borax powder;
[0036] (b) Put 100kg of industrial salt into an iron drum and put it in a well-type furnace to raise the temperature to 320°C, keep it warm and bake for 1.5 hours, continue to bake for 6 hours after the power is turned off, and take it out when the furnace temp...
