Abstract

The utility model relates to an alloy baking device. A gas pipe and an air duct are fixed at the inner bottom of an alloy hopper, the air duct is communicated with the gas pipe, and burner nozzles are evenly distributed on the gas pipe. The gas pipe and the air duct stretches out of the alloy hopper, the gas pipe and the air duct stretching out of the alloy hopper are in series connection with a gas valve and an air compression wind valve respectively. The alloy baking device is simple in structure, high in heat efficiency, and sufficient and even in baking.

Description

Alloy baking device

Technical field

The utility model relates to the apparatus for baking of a kind of heater, particularly alloy.

Background technology

For reducing hydrogen source in molten steel, general steel mill all toasts the alloy adding in steelmaking process, auxiliary material, the alloy baking stove that most of producer adopts specialized factory to make, meet adding the temperature of alloy, accurately weighing and the requirement such as gas safety use, but in refining link, when molten steel composition is finely tuned, need to frequently feed in raw material, small lot is reinforced, this class alloy baking stove is wasted one's talent on a petty job with regard to some, uses very inconvenient.Solution is in primary alloy hopper, to insert a gas pipe of having lighted carry out edge heating or every steel plate, hopper heated below at alloy hopper at present, and these alloy baking devices often do not reach desired temperature, and heating effect is poor.

Summary of the invention

In order to overcome the shortcoming of prior art, the utility model provides a kind of alloy baking device, and it is simple in structure, and thermal effect is high, and baking fully, evenly.

The technical scheme in the invention for solving the technical problem is: the fixing gas pipe of inner bottom part and the airduct of alloy hopper, airduct communicates with gas pipe, uniform burner on gas pipe, gas pipe and airduct stretch out alloy hopper, and the gas pipe and the airduct that stretch out alloy hopper are connected in series respectively gas valve and pneumatics air valve.

The utility model alloy directly heats, and heat energy is fully used, and thermal effect is high; Alloy is Omnidirectional heating from top to bottom, and alloy baking fully, evenly; Light at alloy surface, facilitate ignition operation; Bassoon passes into pneumatics wind, ensures that coal gas does not extinguish on the one hand, on the other hand apparatus for baking is played to cooling effect, does not make high temperature alloy directly contact coal gas inner tube, ensures that coal gas uses safety.

Brief description of the drawings

Below in conjunction with drawings and Examples, this utility model is further illustrated.

Schematic diagram when Fig. 1 is the utility model.

Detailed description of the invention

As shown in Figure 1, the fixing gas pipe 2 of inner bottom part and the airduct 4 of alloy hopper 1, airduct 4 communicates with gas pipe 2, uniform burner 3 on gas pipe 2, gas pipe 2 and airduct 4 stretch out alloy hopper 1, and the gas pipe 2 and the airduct 4 that stretch out alloy hopper 1 are connected in series respectively gas valve 6 and pneumatics air valve 5.

Described burner 3 is horizontal direction, can prevent from stopping up.

Described gas pipe 2 and airduct 4 in alloy hopper 1 is concentric structure, i.e. the mode of large pipe box tubule, and tubule communicates with gas pipe 2, and bassoon communicates with airduct 4, uniform burner 3 on the tube wall of bassoon, burner 3 communicates with gas pipe 2 and airduct 4 simultaneously.

Described burner 3 is concentric structure, i.e. the mode of large borehole jack aperture, and aperture communicates with gas pipe 2, and macropore communicates with airduct 4.

In the time that alloy joins alloy hopper 1, first above alloy hopper, light combustible, in gas pipe 2 and airduct 4, pass into gas, gas can rise to alloy hopper 1 top by the gap of alloy block, and in the time running into the combustible of having lighted, coal gas will be lighted.Pass into pneumatics wind and can make coal gas just take fire at side opening mouth, and do not extinguish, so just can ensure alloy comprehensive heating from top to bottom, and in heating process, ensured the use safety of coal gas.If do not needed to heat time, first close coal gas, then close pneumatics wind, with the safety that ensures that coal gas uses.In whole production process, alloy heated baking always, post personnel are sustainable to finely tune molten steel from feeding in hopper, when alloy is few in hopper, can discontinuity add alloy to hopper.
