Long lifespan, it is with good economic efficiency.
Description of the drawings
Fig. 1 is the utility model stereoscopic schematic diagram；
Fig. 2 is the utility model upward view；
Wherein, 1, cover board, 2, burner, 3, ventilation pipe, 4, circle convex platform, 5, blowing mouth.
Specific implementation mode
Below in conjunction with the accompanying drawings and specific embodiment is described in further details the utility model：
The utility model discloses a kind of pre-heated steel ladle roasters, for being toasted to steel ladle, to ensure
The performance of steel ladle.Here is the specific embodiment of the roaster：
Steel ladle roaster described in the utility model is pre-heated, and as shown in figure institute 1, Fig. 2, which includes cover board
1 and the burner 2 in 1 lower end of cover board is set.Burner 2 makes the lower face of cover board 1 be in the state of high temperature by burn gas fuel,
Then cover board 1 is directed at steel ladle, and then realizes the baking to steel ladle.Usual cover board 1 is circle, and the setting of burner 2 is being covered
The center of plate 1, convenient for comprehensively being heated to cover board 1.
Burner 2 is connected to ventilation pipe 3 in the utility model, ventilation pipe 3 also be arranged valvular gas pipeline and
Air pipeline is connected to.The gas of gas pipeline and air pipeline is passed through ventilation pipe and mix and then exist by ventilation pipe 3
Combustion heating is carried out at burner 2.Both valve on gas pipeline and air pipeline is capable of the flow of regulating gas and air, make
Between ratio be in range appropriate.Gas pipeline and air pipeline are typically to convey gas by air blower or air-introduced machine.
The utility model, which is provided with pulse-control system, to be opened and controls the mode of heating of burner, the particularly pulse
There is control system temperature and time control model, the pulse-control system to be heated using periodically pulsing formula.When adopting
When with temp-controled mode, set temperature section, when temperature is less than minimum temperature, burner 2 is in normal heating state, works as temperature
When degree is higher than maximum temperature, burner 2 stops heating and is kept the temperature.The temperature range set under typical temperature control model is 400
DEG C~800 DEG C.Between when employed when control model.Heating cycle and soak cycle are set, such as each period is 1 minute,
Middle 10s be heating cycle 50s be soak cycle.Under the control of pulse-control system, which can always be in more
Suitable state of temperature, temperature will not be too high and then can save the energy；Temperature will not be too low, can quickly reach when in use
To defined heating temperature.In the roaster course of work, cover board 1 is in the state of preheating always.The roaster makes cover board
Always it is in pre- Warm status, it is low from working efficiency caused by room temperature heating to solve the problems, such as that each use is required for.Together
When, cover board is in turn avoided for a long time in flimsy problem caused by the condition of high temperature by pulse-control system.By pulse
But control system improves the performance of the steel ladle roaster in the control of steel ladle roaster.
