Description
Technical field
The invention belongs to blank heating technical fields, and in particular to a kind of blank heating method during Rolling Production.
Background technique
Currently, blank heating during Rolling Production is mainly in the following ways:
1, continuous-type furnace heats
Continuous-type furnace heating is most important blank heating mode during Rolling Production, and blank is sent into not by refueling facilities
With the continuous-type furnace of form.In Bar Wire Product production, mainly walking beam furnace, blank are moved by walking beam by entrance
It moves to outlet, realizes the purpose of heating.Since dynamic beam needs upwardly and forwardly to move in the state of bearing whole furnace charges, institute
To need to consume biggish energy.In addition, generating more heat loss, the thermal efficiency of heating furnace since furnace bottom space is larger
It is lower.In tubing production, mainly rotary heating furnace, blank are sent into furnace by manipulator, and furnace bottom rotates a station, then
It is sent into second blank, furnace bottom rotates a station again, until first blank reaches outlet, the base that will be heated by manipulator
Material takes out.
The shortcomings that this heating method is: (1) furnace bottom needs to move in the state of bearing whole furnace charges, bottom construction
Weight, operation consumption energy are more；(2) furnace bottom space is big, and furnace body gap is more, and heat loss is serious；(3) stove is run at high temperature,
When rolling has some setbacks, blank is detained in furnace or is pushed out outside furnace, and thermal loss and blank is caused to lose；(4) blank is in height
The temperature state time is long, and scaling loss is serious；(5) furnace body size is big, and yield per unit area is low；(6) stove positional distance milling train is remote, blank
Thermal loss is big.
2, chamber type electric resistance furnace heats
The heating method is packed into blank in furnace by batch, after reaching rolling temperature using various forms of chamber type electric resistance furnaces
Sequence is come out of the stove, and mill milling is sent into.
The shortcomings which is: (1) stove heating efficiency is limited, does not adapt to the rolling rhythm of high yield energy milling train；(2) it presses
Batch shove charge, energy consumption is big, and blank scaling loss is more；(3) hot blank long operational time outside furnace, thermal loss are big.
3. induction heating
The heating method is, quickly by blank heating, to be then fed into mill milling using medium frequency induction heater.
The shortcomings which is: (1) heating efficiency is limited, does not adapt to the rolling rhythm of high yield energy milling train；(2) it heats not
Uniformly, center portion and surface temperature difference are big, especially for major diameter blank, need further soaking；(3) material, size of blank,
Shape is restricted；(4) when the power supply quality fluctuation of power grid, heating temperature is unstable；(5), heating rate is too fast, and over control is difficult
With control.
Three of the above heating method uses a heating furnace, using different heating cycles, primary heating to rolling temperature
Degree.The preheating of heating cycle, heating, soaking stage are completed in a heating furnace.Such heating method is suitable for base
Expect the identical high volume production process of material, is unsuitable for the Rolling Production process of multi items, small lot.
Summary of the invention
In view of the above technical problems, the present invention provides a kind of blank heating method during Rolling Production, this method
Temperature is tentatively improved using waste heat, is heated to required temperature by preheating the temperature control chamber of temperature control heating furnace later, meets production institute
It needs.
In order to solve the above-mentioned technical problem, the technical solution adopted by the present invention are as follows:
A kind of blank heating method during Rolling Production, comprising the following steps:
The waste heat that S1, blank enter preheating temperature control heating furnace is intracavitary, is carried out by the waste heat in preheating temperature control heating furnace to blank
Preliminary heating；
Blank after S2, preliminary preheating is heated by primary heating furnace；
Blank after S3, preheating enter preheating temperature control heating furnace temperature control it is intracavitary heated, be heated to rolling temperature；
S4, S3 is heated after blank be sent into milling train roll.
Connection between the preheating cavity and temperature control chamber of temperature control heating furnace is preheated, wherein temperature control chamber temperature is higher than preheating cavity, by controlling
Warm chamber provides heat source for preheating cavity.
Preheating temperature control heating furnace is arranged on roll line, and blank is directly entered milling train and rolls after leaving preheating temperature control heating furnace
System.
The preheating temperature of S2 is lower than 100~300 DEG C of rolling temperature of S3.
In arranging up and down, waste heat chamber is located at the lower section of temperature control chamber for waste heat chamber and temperature control chamber.
Compared with prior art, the present invention having the beneficial effect that
The main heating process of blank is carried out in primary heating furnace, avoids the phenomenon that blank generates overheat, burning or even burns,
Efficiently reduce metal loss.The waste heat that blank passes through preheating temperature control heating furnace first tentatively promotes temperature, is effectively utilized
The waste heat generated in production process, to alleviate the burden of primary heating furnace.
The rolling temperature of blank is adjusted by preheating temperature control heating furnace, blank tapping temperature is accurate, can satisfy different
Requirement of the rolling mill practice to blank temperature.
Temperature control heating furnace is preheated close to inlet of rolling mill, temperature drop loss is few, and the head and tail temperature difference of blank is small.The time of primary heating
Can be very long, it can guarantee the thermal stress for eliminating blank, homogeneous heating；Primary heating furnace is run at a lower temperature, furnace body
Cost reduces, and the service life of stove extends；Tempus intercalare is rolled, primary heating furnace, which is in, to preheat temperature control with keeping warm mode
Heating furnace is in can be with blowing out state, and thermal loss is small.
