Abstract
The invention belongs to the field of roller production and relates to a roller cold-treatment technology. The roller cold-treatment technology comprises the following steps of putting a quenched roller into a treatment waiting tank, immersing the roller needing to be treated into water in a water cooling tank for 2-3 hours, simultaneously, feeding liquid carbon dioxide into a low-temperature treatment tank so that the liquid carbon dioxide and ethanol in the low-temperature treatment tank are mixed fully and a temperature of the low-temperature treatment tank is reduced to -70 DEG C, simultaneously, discharging cool gas produced in the low-temperature treatment tank and needing to be subjected to pressure reduction into the water cooling tank, cooling water in the water cooling tank, taking out the roller cooled in the water cooling tank, carrying out air drying, putting the dried roller into the low-temperature treatment tank, immersing the roller in the ethanol for 2-3 hours, taking out the roller from the low-temperature treatment tank, putting the roller into a water treatment tank so that the roller is heated fast, immersing the roller in water for 1-2 hours, taking out the roller from the water, and feeding the roller to a tempering unit. The roller cold-treatment technology shortens a production period and reduces energy waste.
Description
Technical field
The invention belongs to the production method of roll, particularly a kind of cold treatment process of roll.
Background technology
After roller quenching, air cooling carries out deepfreeze again to room temperature, and air cooling to room temperature by the unusual 1-2 days that needs in season, the production cycle is long; In actual production, for catching up with production schedule often just directly to put into the deepfreeze of-60 ° of deepfreeze grooves at roll air cooling to certain temperature (a little higher than room temperature), Liquid carbon dioxide is caused to waste.
Summary of the invention
The present invention is directed to the deficiency of existing production technique, the technique of breaker roll deepfreeze is improved, add the process of water-cooled process, effectively shorten the production cycle long, the defect that liquid carbon dioxide consumption is serious, rises again through water treatment trough after cold treatment simultaneously, effectively can shorten the temperature rising-time of roll, shorten the heat-up time of tempering stove, save electricity consumption.
The present invention is achieved through the following technical solutions:
1, Roller cold-treatment technology, is characterized in that: present treatment technique comprises the steps:
Pending groove put into by roll after A, quenching;
B, pending roll is put into water cooling tank, be immersed in water, keep 2-3 hour, liquid carbon dioxide is injected in subzero treatment groove simultaneously, and fully mix with the ethanol in subzero treatment groove, make the temperature of subzero treatment groove drop to-70 DEG C, the cold air of the needs decompression simultaneously produced in subzero treatment groove enters in water cooling tank, lowers the temperature to the water in water cooling tank;
C, the roll after cooled in water cooling tank to be taken out, dry up in atmosphere;
D, the roll dried up is put into subzero treatment groove, immerse in ethanol and keep 2-3 hour;
E, roll rushed in subzero treatment groove and takes out, put into water treatment trough, roll is rapidly heated, and immerses 1-2 hour in water;
F, roll to be taken out from water treatment trough, put into tempering stove, proceed to tempering process.
The present invention has following beneficial effect: the temperature that the present invention enters the temperature of subzero treatment groove and the roll after subzero treatment by water treatment trough breaker roll carries out pre-cooling and pre-intensification, effectively shorten the time required for whole production technique on the one hand, improve production efficiency, also the consumption of liquid carbon dioxide and the power consumption of tempering stove can be reduced on the other hand, save the energy, decrease the waste of the energy.
Embodiment
Roller cold-treatment technology, is characterized in that: present treatment technique comprises the steps:
Pending groove put into by roll after A, quenching;
B, pending roll is put into water cooling tank, be immersed in water, keep 2-3 hour, liquid carbon dioxide is injected in subzero treatment groove simultaneously, and fully mix with the ethanol in subzero treatment groove, make the temperature of subzero treatment groove drop to-70 DEG C, the cold air of the needs decompression simultaneously produced in subzero treatment groove enters in water cooling tank, lowers the temperature to the water in water cooling tank;
C, the roll after cooled in water cooling tank to be taken out, dry up in atmosphere;
D, the roll dried up is put into subzero treatment groove, immerse in ethanol and keep 2-3 hour;
E, roll rushed in subzero treatment groove and takes out, put into water treatment trough, roll is rapidly heated, and immerses 1-2 hour in water;
F, roll to be taken out from water treatment trough, put into tempering stove, proceed to tempering process.
The present invention has following beneficial effect: the temperature that the present invention enters the temperature of subzero treatment groove and the roll after subzero treatment by water treatment trough breaker roll carries out pre-cooling and pre-intensification, effectively shorten the time required for whole production technique on the one hand, improve production efficiency, also the consumption of liquid carbon dioxide and the power consumption of tempering stove can be reduced on the other hand, save the energy, decrease the waste of the energy.
