Abstract
The utility model relates to roller quenching devices and particularly relates to a quenching heater applicable to rollers. The quenching heater comprises a furnace body and a supporting platform which is arranged at the bottom of the internal cavity of the furnace body and is used for supporting a roller workpiece, wherein work frequency induction coils and infrared temperature measuring probes are mounted on the internal wall of the furnace body and are controlled by a PLC (Programmable Logic Controller) control chip. During use, acquired temperature signals are fed back to the PLC control chip by the infrared temperature measuring probes, and the PLC control chip controls the heating temperature and heating rate of the work frequency induction coils, so that the heat treatment on the roller workpiece placed on the supporting platform is realized. Due to the structure, the quenching heater has the advantages that the energy consumption is reduced, the heating is uniform, the roller workpiece is not subjected to decarbonization and has fine crystal grains, and the heat treatment processing quality for the rollers is improved.
Description
Technical field
The utility model relates to the roller quenching device, specifically a kind of tiny quenching heating device that is applicable to roll of energy consumption, homogeneous heating, not decarburization and crystal grain that reduces.
Background technology
Roll is widely used in the industry-by-industry that iron and steel is made, and its manufacturing processed generally is made of casting, thermal treatment (being commonly referred to quenching) and mechanical workout.Determine the principal element of roller performance except material and castability, mainly determined by thermal treatment.
Natural gas heating, two kinds of type of heating of heating by electric cooker are often adopted in the roll thermal treatment of prior art.For roll, no matter be monoblock type or built-up type, because roll weight is large, volume is large, and two kinds of type of heating often cause the heat treating faults such as heating inequality, decarburization, coarse grains.Cause the overheated burning defective at roller core position for the monoblock type roll is commonly used again, thereby cause roll that the roll breakage phenomenon in use occurs.
In sum, the roll thermal treatment of prior art is that the roll working lining is heated together with structure position, because the volume reason causes heating uneven; Adopt to extend the mode of process time, often cause structural part position coarse grains, roll breakage easily occurs; Adopt the natural gas heating often to cause the decarburization phenomenon; Plant efficiency is low, and energy consumption is high, and is seriously polluted, and maintenance cost is high.In a word, the roll thermal treatment of prior art heating is uneven, and decarburization and coarse grains cause roll that the roll breakage phenomenon in use occurs.
Summary of the invention
The purpose of this utility model is to provide a kind of tiny quenching heating device that is applicable to roll of energy consumption, homogeneous heating, not decarburization and crystal grain that reduces.
For realizing that the technical scheme that the utility model above-mentioned purpose adopts is: a kind of quenching heating device that is applicable to roll, comprise body of heater, be arranged on the brace table that is used for the back-up roll workpiece of body of heater intracavity bottom; Wherein: the inwall of described body of heater is equipped with line-frequency induction coil and infrared thermometry probe, described line-frequency induction coil and infrared thermometry probe are controlled by the PLC control strip, by the infrared thermometry probe, the temperature signal that gathers is fed back to the PLC control strip, the PLC control strip is controlled Heating temperature and the rate of heating of line-frequency induction coil according to the temperature signal that receives, and completes being placed on the thermal treatment of the roll workpiece on brace table.
Due to said structure, infrared thermometry probe breaker roll surface temperature Real-time Collection of the present utility model, the line-frequency induction coil of being controlled by the PLC control strip carries out real-time feed to the heat treated Heating temperature of breaker roll and rate of heating, make that roll is heated evenly, not decarburization and crystal grain tiny, and energy consumption is low.
Description of drawings
The utility model can further illustrate by the indefiniteness embodiment that accompanying drawing provides.
Fig. 1 is structural representation of the present utility model.
In figure: 1, body of heater; 2, line-frequency induction coil; 3, roll workpiece; 4, brace table; 5, infrared thermometry probe.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
Referring to accompanying drawing 1, a kind of quenching heating device that is applicable to roll comprises body of heater 1, is arranged on the brace table 4 that is used for back-up roll workpiece 3 of body of heater 1 intracavity bottom; Wherein: the inwall of described body of heater 1 is equipped with line-frequency induction coil 2 and infrared thermometry probe 5, and this line-frequency induction coil 2 and infrared thermometry probe 5 are controlled by the PLC control strip; During use, infrared thermometry probe 5 feeds back to the PLC control strip with the temperature signal that gathers, by the infrared thermometry probe, the temperature signal that gathers is fed back to the PLC control strip, the PLC control strip is controlled Heating temperature and the rate of heating of line-frequency induction coil 2 according to the temperature signal that receives, and completes being placed on the thermal treatment of the roll workpiece 3 on brace table 4.
In the present embodiment, after infrared thermometry probe 5 feeds back to the PLC control strip with the temperature signal that gathers, the PLC control strip calculates the actual temperature on workpiece (being roll 3) surface according to the temperature signal that receives, calculate effective heating thickness of workpiece according to the folding thermal conductivity again, thereby calculate workpiece actual required Heating temperature and two key factors of rate of heating; The PLC control strip is controlled Heating temperature and the rate of heating supply that line-frequency induction coil 2 breaker roll workpiece 3 are heat-treated again.In this process, infrared thermometry probe 5 breaker roll 3 surface temperature Real-time Collections, carry out real-time feed by 2 pairs of heat treated Heating temperatures of breaker roll 3 of line-frequency induction coil and rate of heating that the PLC control strip is controlled, make that roll 3 is heated evenly, not decarburization and crystal grain tiny, and energy consumption is low.Make roll 3 reduce the occurrence rate of roll breakage phenomenon in use procedure.
PLC control strip in said structure, line-frequency induction coil 2 and infrared thermometry probe 5 adopt the commercially available prod.
Obviously, all embodiment of foregoing description are a part of embodiment of the present utility model, rather than whole embodiment.Based on embodiment of the present utility model, those of ordinary skills are not making all other embodiment that obtain under the creative work prerequisite, all belong to the category of the utility model protection.
Due to described structure, the automatic adjusting that has realized Heating temperature and speed falls in the utility model, has reduced energy consumption, homogeneous heating, the 3 not decarburizations of roll workpiece and crystal grain tiny, has improved roll heat treatment process quality.
