Description

Bottom ring of submerged arc furnace

Technical Field

The utility model relates to a hot stove part field in ore deposit especially relates to a hot stove bottom ring in ore deposit.

Background

The submerged arc furnace is also called electric arc furnace or resistance furnace. It is mainly used for reducing and smelting raw materials such as ore, carbonaceous reducing agent and solvent. When the temperature is too high during ore smelting, the pressure ring is easy to be lost, and the bottom ring is a cooling device for cooling the pressure ring, so that the service life of the pressure ring is prolonged. The existing bottom ring has poor cooling effect and short service life.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a bottom ring of a submerged arc furnace.

The innovation point of the utility model is that the arrangement area of the cooling pipes of the bottom ring is increased, the cooling efficiency is improved,

in order to realize the purpose of the utility model, the technical proposal of the utility model is that:

the utility model provides a hot stove bottom ring in ore deposit, including bottom ring body, bottom ring body comprises a plurality of arc rings, be equipped with a plurality of lugs that are used for fixed connection on the hot stove in ore deposit on the arc ring, a serial communication port, the arc ring include a plurality of sections arrange side by side circular-arc cooling tube and with cooling tube both ends fixed connection's connector, fixed connection between the cooling tube, be equipped with a plurality of discharge orifices in the connector, the intra-annular cooling tube of an arc relies on discharge orifice intercommunication to form a inflection shape pipeline, be equipped with the inlet tube on the connector of cooling tube one end, be equipped with the outlet pipe on the connector of the other end. The cooling water flows into to the outlet pipe from the inlet tube and flows out, has taken away the heat that absorbs on the cooling tube pipe wall, and the cooling area of the bottom ring of this kind of structure is big, the difficult scale deposit in the cooling tube, life cycle is long.

Further, the cooling pipe is a copper cooling pipe. The heat conductivity and the corrosion resistance of copper material are good, and the motor is surrounded at the bottom, and the bottom ring of iron material can produce a large amount of eddies, increases the consumption of hot stove in ore deposit, and the copper material can not produce the eddies.

Further, the arc ring is provided with two. The assembly with the pressure ring is convenient.

Further, the cooling pipes are connected in a welding mode. The welding connection is firm, and the cost is low.

Further, the inner wall of the cooling pipe is S-shaped. Turbulence is easily formed in the cooling pipe, the retention time of cooling water is prolonged, and the cooling effect is better.

Furthermore, a filtering device is arranged on the water inlet pipe. The filtering device effectively filters impurities in the cooling water and prevents the cooling pipe from being blocked by the impurities.

The utility model has the advantages that:

1. the utility model discloses the cooling area of bottom ring is big, the difficult scale deposit in the cooling tube, life cycle is long.

2. The utility model discloses well copper product's cooling tube heat conductivity is good with corrosion resistance, because the motor is surrounded to the bottom, the bottom ring of iron material can produce a large amount of vortexes, increases the consumption of the hot stove in ore deposit, and the copper product can not produce the vortex.
