Problems solved by technology

The flame temperature at the outlet of the conventional combustion device is very high, which is prone to local overheating, while the local overheating of the diffusion furnace is likely to cause steel wire spheroidization, so it is not suitable for use on the diffusion furnace

Embodiment Construction

[0017] The present invention will be described in further detail below through specific examples.

[0018] Such as figure 1 and figure 2 As shown, a combustion device of an electroplated brass steel wire diffusion furnace includes a burner and a mixed gas supply pipe connected to the burner, and the burner is installed on the side of the furnace body of the diffusion furnace.

[0019] The burner includes a burner body and an outer sleeve fixed on the outside of the burner body. A guide cooling channel is formed between the outer sleeve and the burner body. The diversion inlet nozzle connected with the flow pipeline; in order to facilitate better fixing with the furnace body, a connecting flange is welded on the outer sleeve. Such as figure 1 As shown, the diversion pipeline includes an upstream air inlet pipe section, a preheating pipe section and a downstream connecting pipe section connected in sequence, the upstream air inlet pipe section is used to communicate with the...

Abstract

The invention discloses a combustion device of an electroplating brass steel wire diffusion furnace. The combustion device comprises a combustor, and a mixed gas supply pipe connected with the combustor; the combustor comprises a combustor body, and an outer sleeve fixedly sleeving the combustor body; a guide cooling channel is formed between the outer sleeve and the combustor body; the outer sleeve is provided with a guide intake nozzle for communicating with a guide pipeline; one end of the combustor body is a mounting end, and a nozzle mounting hole is formed; the other end of the combustorbody is a spraying end, and a spraying hole is formed; a combustion chamber is formed in the combustor body, and comprises a flaring section and a shrinkage section connected with each other; a smallend of the flaring end communicates with the nozzle mounting hole through a communicating hole; a small end of the shrinkage section communicates with the spraying hole; a nozzle of the mixed gas supply pipe is fixed on the nozzle mounting hole; and the mixed gas supply pipe is provided with a spark plug. The combustion device can inhibit higher outlet temperature of the combustor to achieve uniform heating of the diffusion furnace.

Description

technical field [0001] The invention relates to a combustion device, in particular to a combustion device for an electroplated brass steel wire diffusion furnace. Background technique [0002] Electroplated brass steel wire diffusion furnace is the key equipment for the production of steel cord brass steel wire. The diffusion of the zinc-copper coating on the surface of the steel wire is realized when the zinc-copper coating is heated, and the zinc-copper atoms are mutually displaced and moderately mixed. The zinc-copper coating on the surface of the steel wire has been preheated, heated and kept warm to complete the potential energy activation, rapid diffusion and atom stabilization of the zinc-copper atoms to produce a brass alloy. The interdiffusion between zinc and copper atoms at different speeds is a kind of unstable diffusion. This is because the concentration, number and velocity of zinc and copper atoms vary with time during diffusion. Because the density of zinc...
