Description
Technical field
The utility model belongs to the control refrigerating unit in a kind of cold-rolled silicon steel tape heat-treatment production line.Be particularly related to a kind of novel silicon steel band heat-treatment production line and control refrigerating unit.
Background technology
Cold-rolled silicon steel tape thermal treatment cooling technology is to require in recent years more and more higher a kind of technology, especially for the higher specialty products of ask for something (silicon strip as name oriented in height or non-oriented silicon steel strip etc.), when controlling the speed of cooling of silicon strip is strict, along the temperature head of the width of silicon strip, in process of cooling, also there is strict demand.The conventional type of cooling has two kinds of modes of the cooling and direct gas flow of brief introduction radiation winding-up, radiation is cooling is applicable to that speed of cooling is slow, temperature is higher, need the process for cooling of accurate control speed, jet flow is cooling applicable fast with speed of cooling, and speed of cooling is controlled does not need too strict process for cooling.The cooling employing of traditional radiation " I " type cold emission pipe, with oriented silicon steel band traffic direction at right angle setting, total speed of cooling can be adjusted, but can not regulate along oriented silicon steel band width cooling power.This just causes oriented silicon steel band to lean on the cooling power of furnace wall side obviously fast than the cooling power at cooling room center, easily causes the buckling deformation of band steel.
Summary of the invention
The purpose of this utility model is to provide novel silicon steel band heat-treatment production line and controls refrigerating unit.Technical problem to be solved is: will become many identical cold emission pipes of even number to be divided into two groups, along silicon strip traffic direction and at band steel, be evenly arranged up and down, by being adjusted at one by one the cooling power of many groups cold emission pipe setting up and down on width, can adjust the speed of cooling of silicon strip broad ways, be reduced in the temperature head of silicon strip broad ways in process of cooling.
The technical solution of the utility model is:
Novel silicon steel band heat-treatment production line is controlled a refrigerating unit, it is characterized in that: row's cold emission pipe outer tube (2) is respectively housed up and down in refrigerating unit housing (1), has cold emission pipe inner tube (3) in cold emission pipe outer tube (2); Outside cold emission pipe inner tube (3) outside refrigerating unit housing (1), cooling airflow flowmeter (4) is housed, on cold emission pipe inner tube (2) outer end outside refrigerating unit housing (1), cooling airflow adjustable valve (5) is housed, cold emission pipe outer tube (2) outside refrigerating unit housing (1) is connected on cooling air header box (6), it is upper that cooling air header box (6) is connected to cooling air induced draft fan (7), and silicon strip support roll (8) is housed in refrigerating unit housing (1).
The cooling unit that many covers of one-tenth even number are comprised of cold emission pipe outer tube (2), cold emission pipe inner tube (3) is divided into upper and lower two groups, be arranged in upper and lower in refrigerating unit housing (1), cold emission pipe outer tube (2) is equidistant, parallel is placed in that silicon strip (9) is upper and lower, the trend of cold emission pipe outer tube (2) is consistent with silicon strip (9) traffic direction.
Effect of the present utility model is:
Be characterized in that two groups of cold emission pipes are parallel with heat-treatment production line traffic direction, at silicon strip, be evenly arranged up and down, can on silicon strip width, adjust cooling intensity, guarantee that silicon strip speed of cooling on cross section is even, avoid silicon strip because of cross section thermal stress deformation.Be particularly suitable for the control process of cooling of the smooth heat-treatment production line of oriented silicon steel hot drawing.Can be convenient, quantitative adjusting is along the cooling power of silicon strip width, according to processing requirement, controls silicon strip speed of cooling, prevents the buckling deformation because of inhomogeneous cooling on width, significantly improved the strip shape quality after silicon strip thermal treatment.

In figure:
(1) refrigerating unit housing, (2) cold emission pipe outer tube, (3) cold emission pipe inner tube, (4) cooling airflow flowmeter, (5) cooling airflow adjustable valve, (6) cooling air header box, (7) cooling air induced draft fan, (8) silicon strip support roll, (9) silicon strip.
Embodiment
A kind of novel silicon steel band heat-treatment production line is controlled refrigerating unit by refrigerating unit housing (1), cold emission pipe outer tube (2), cold emission pipe inner tube (3), cooling airflow flowmeter (4), cooling airflow adjustable valve (5), cooling air header box (6), cooling air induced draft fan (7) by being full of protective atmosphere as shown in the figure; silicon strip support roll (8), silicon strip (9) forms.
The utility model " novel silicon steel band heat-treatment production line is controlled refrigerating unit " is arranged on to the slow control cooling section of silicon strip continuous heat treatment production line.The cooling units that many covers are comprised of cold emission pipe outer tube (2), cold emission pipe inner tube (3) etc. divide two groups to be arranged in up and down in refrigerating unit housing (1), and equidistant, are parallelly placed in silicon strip (9) up and down.
The entrance outlet of refrigerating unit housing (1) is provided with respectively silicon strip support roll (8), and silicon strip (9) passes through " novel silicon steel band heat-treatment production line is controlled refrigerating unit " with process speed under the support of silicon strip support roll (8).
Under the effect of negative pressure, cooling air by cooling airflow flowmeter (4), cooling airflow adjustable valve (5), enter into cold emission pipe inner tube (3) and turn back in its end and enter into cold emission pipe outer tube (2).Cooling air along through the interlayer rapid flow between cold emission pipe inner tube (3) and cold emission pipe outer tube (2) and with high temperature silicon steel band (9) heat exchange after enter into cooling air header box (6), finally the wind induced draft fan (7) that is cooled enters atmosphere.
