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 to room temperature is carried out deepfreeze again, and air cooling unusual needs 1-2 days to room temperature by season, and the production cycle is long; In actual production, often just directly put into-60 ° of deepfreeze groove deepfreezes in roll air cooling to certain temperature (a little higher than room temperature) for catching up with production schedule, cause the Liquid carbon dioxide 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, increased the process that water-cooled is processed, effectively shortened the production cycle long, the defective that liquid carbon dioxide consumption is serious is risen again through water treatment trough after cold treatment simultaneously, can effectively shorten the temperature rise time of roll, shorten the heat-up time of tempering stove, saved electricity consumption.
The present invention is achieved through the following technical solutions:
1, roll cold treatment process, it is characterized in that: this treatment process comprises the steps:
Roll after A, quenching is put into pending groove;
B, pending roll is put into water cooling tank, be immersed in water, kept 2-3 hour, liquid carbon dioxide is injected in the subzero treatment groove simultaneously, and fully mix with ethanol in the subzero treatment groove, the temperature of subzero treatment groove is dropped to-70 ℃, the cold air of the needs decompression that produces in the subzero treatment groove simultaneously enters in water cooling tank, and the water in water cooling tank is lowered the temperature;
C, will be in water cooling tank cooling roll later take out, and dry up in air;
D, the roll that dries up is put into the subzero treatment groove, be immersed in ethanol and kept 2-3 hour;
E, roll is rushed in the subzero treatment groove take out, put into water treatment trough, roll is rapidly heated, and immerses 1-2 hour in water;
F, roll is taken out from water treatment trough, put into tempering stove, change tempering process over to.
The present invention has following beneficial effect: the present invention enters the temperature of subzero treatment groove and carries out pre-cooling and pre-the intensification through the temperature of subzero treatment roll later by the water treatment trough breaker roll, effectively shortened the needed time of whole production technique on the one hand, improved production efficiency, also can reduce on the other hand the consumption of liquid carbon dioxide and the power consumption of tempering stove, save the energy, reduced the waste of the energy.
Embodiment
The roll cold treatment process is characterized in that: this treatment process comprises the steps:
Roll after A, quenching is put into pending groove;
B, pending roll is put into water cooling tank, be immersed in water, kept 2-3 hour, liquid carbon dioxide is injected in the subzero treatment groove simultaneously, and fully mix with ethanol in the subzero treatment groove, the temperature of subzero treatment groove is dropped to-70 ℃, the cold air of the needs decompression that produces in the subzero treatment groove simultaneously enters in water cooling tank, and the water in water cooling tank is lowered the temperature;
C, will be in water cooling tank cooling roll later take out, and dry up in air;
D, the roll that dries up is put into the subzero treatment groove, be immersed in ethanol and kept 2-3 hour;
E, roll is rushed in the subzero treatment groove take out, put into water treatment trough, roll is rapidly heated, and immerses 1-2 hour in water;
F, roll is taken out from water treatment trough, put into tempering stove, change tempering process over to.
The present invention has following beneficial effect: the present invention enters the temperature of subzero treatment groove and carries out pre-cooling and pre-the intensification through the temperature of subzero treatment roll later by the water treatment trough breaker roll, effectively shortened the needed time of whole production technique on the one hand, improved production efficiency, also can reduce on the other hand the consumption of liquid carbon dioxide and the power consumption of tempering stove, save the energy, reduced the waste of the energy.
