The invention relates to an industrial resistance furnace, in particular to an RTC-1000-12 industrial resistance furnace. The heating resistance tape of the resistance furnace is divided into ten zones in total, and each zone is of 100KW three-phase star-shaped connection; the resistance furnace is characterized in that ten A-phase heating resistors and ten B-phase heating resistors are arranged at the furnace side, while eight C-phase heating resistors are arranged on a trolley, one C-phase heating resistor is arranged on each furnace door, six C-phase heating resistors are arranged in the middle part of the trolley, and two C-phase heating resistors are arranged at the two end part of the trolley. The power partitioned allocation configuration method is used for solving the problem that heating sources are reduced due to lots of burning loss and breakage faults of the resistance tape caused by unreasonable resistance distribution of the RTC-1000-12 industrial resistance furnace at present.
Description
Technical field
The present invention relates to a kind of industrial resistance furnace, particularly a kind of RTC-1000-12 industrial resistance furnace.
Background technology
RTC-1000-12 industrial resistance furnace is a kind of key equipment of smelting steel, the main thermal treatment work of being responsible for clad steel plate, resistance furnace is mainly by body of heater, fire door, chassis forms, Heating element resistive band is distributed in respectively body of heater both sides, on fire door and chassis, resistive band circuit is divided into 10Ge district and controls, each district's resistive band is Y-connection, power is 100KW, every phase power is about 33KW, the body of heater both sides that are distributed as of resistive band integral body are 10 A heat phase resistance, 6 B heat phase resistance, two fire doors are 4 B heat phase resistance, chassis is 10 C heat phase resistance, in service at resistance furnace, often there is the fault that chassis resistive band and fire door resistive band are in operation and rupture, and can't hard stop (in stove, temperature also needs tape jam that this stove steel plate hot is handled when 700-800 spends) during operating resistance furnace tape jam, so just cause the heat treatment time of resistance furnace to strengthen that (fault causes heating electric stopband power reduction, thermal value reduces), and the heat treatment time of resistance furnace strengthens the working hour that has increased other resistive bands, the fault that causes resistance furnace increases and (is mainly resistive band over-heated fault, each district's supply lead and electrical connector over-heated fault), and the raising of failure rate has restricted the operation of 1000KW resistance furnace.Through the operation of resistance furnace and trouble analysis are summed up to following 2 inefficiencies that cause 2# resistance furnace stove:
1, the surperficial effective dimensions of chassis is long 10 meters wide 3 meters, at trolley surface resistive band, be arranged as 10 C phases, heating power accounts for 1/3 of total power, trolley surface heating power is larger, and resistive band arrangement is also compact, and chassis resistive band top also has heat-resisting cover plate, the heat that resistive band produces in approximate airtight space is larger, in resistance furnace operational process, the oxide skin that heat treated steel plate produces is in resistance trough of belt is infiltrated in protective cover plate gap,, the oxide skin in infiltrating resistance trough of belt can cause resistive band short circuit while reaching a certain amount of and blow resistive band;
2, the resistive band on fire door surface is hanging type, at fire door surface alignment, has two B phases, and arranging density is large, has reduced the stability of fire door resistive band in fire door moving process, often causes resistive band to come off producing over the ground or short trouble and scaling loss resistive band.
In a word, RTC-1000-12 resistance furnace heating resistor band configuration and chassis, fire door, side wall resistance unreasonable distribution cause resistive band scaling loss and fracture defect many and reduced pyrotoxin.
Summary of the invention
Technical problem to be solved by this invention is: how to solve current RTC-1000-12 industrial resistance furnace resistance unreasonable distribution and cause resistive band scaling loss and fracture defect many and reduced the problem of pyrotoxin.
The technical solution adopted in the present invention is: in the situation that total power is constant, increased the power of furnace side, reduced the power of chassis, fire door, be specially: a kind of RTC-1000-12 industrial resistance furnace power split collocation method, the heating resistor band of this resistance furnace is divided into Shi Ge district, and each district is 100KW three-phase Y-system, 10 A heat phase resistance of furnace side configuration, 10 B heat phase resistance, 8 C heat phase resistance of chassis configuration, two fire doors respectively configure 1 C heat phase resistance; 6 C heat phase resistance are arranged at chassis middle part, and 2 C heat phase resistance are arranged at chassis both ends.
The invention has the beneficial effects as follows: the present invention is in the situation that resistance furnace total power is constant, reduced the power of moving body chassis and fire door, increased the pitch of chassis and fire door resistive band, eliminated the design reasons that causes chassis and fire door resistive band fault, under the state that does not affect thermal treatment process and in the situation that total power is constant, increased the power of side wall, reduced chassis, the power of fire door, reduced the failure rate of resistive band, good (to present resistance wire over-heated fault through operating performance, each district's supply lead and electrical connector over-heated fault did not also occur, other electric elements fault also obviously reduces).Every furnace treatment reason time comes out of the stove than before in advance for about 2 hours.
Embodiment
1, the existing chassis resistive band of RTC-1000-12 industrial resistance furnace is arranged as 10 C phases, arrange compact, resistive band pitch is too close, when penetrating into around resistive band, steel plate oxide skin very easily causes resistive band short circuit over-heated fault, because steel plate oxide skin is inevitably in heat treatment process, so can only increase resistive band pitch
With the sealing of strengthening protection heat-resisting steel sheet and plate, the pitch that increases resistive band in the situation that every phase resistance band power is constant must increase the entire area of resistive band, and the area of trolley surface solidifies, through linking up and determine to arrange 8 C phases on chassis with relevant technologies personnel.Concrete arranged evenly for being 6 C phases at chassis middle part, at chassis both ends, be 2 C phases.
2, existing two fire doors of RTC-1000-12 industrial resistance furnace are arranged as 4 B phases, arranging density is large, in fire door moving process, reduced the stability of fire door resistive band, often cause resistive band to come off producing over the ground or short trouble and scaling loss resistive band fault, therefore reduce fire door resistive band arranging density, the stability that strengthens resistive band is crucial, so arranged respectively 1 C phase on two fire doors
3, the existing burner hearth of RTC-1000-12 industrial resistance furnace both sides are fixed body, and resistive band failure rate is starkly lower than chassis and fire door, so arranged respectively 5 A phases, 5 B phases in burner hearth both sides.
The present invention has carried out redesigning transformation to the heating resistor band of resistance furnace, transformation principle is in the situation that total power is constant, increased the power of side wall, reduced the power (reason: because fire door, chassis band are moving body of chassis, fire door, burner hearth side wall is fixed body, just resistive band has been carried out to layout again for these reasons, the former configuration principle of resistance furnace resistive band is: full stove resistive band is divided into Shi Ge district, each district is that 100KW three-phase is Y-system, furnace side is 10 A phases, 6 B phases; Chassis is 10 C phases; Two fire doors are 4 B phases.Improved configuration principle is: full stove resistive band is divided into Shi Ge district, and each district is that 100KW three-phase is Y-system, and furnace side is 10 A phases, 10 B phases; Chassis is 8 C phases; Two fire doors are 2 C phases).Good (to resistance wire over-heated fault, each district's supply lead and electrical connector over-heated fault did not also occur now through operating performance more than a year after transformation, other electric elements fault also obviously reduces), every furnace treatment reason time comes out of the stove than before in advance for about 2 hours.
